In addition it canto dedicate itself to other compatible, tie, connected and/or complementary activities to its objectsocial.The Enterprise objectives of SEDAPAL to year 2030 orient a:• To assure the sustainability the services of potable water and sewage system,• To improve the quality of the services,• To improve the economic and financial efficiency, and• To facilitate the access to the services of potable water and sewage system.Also, within its Environmental Plan 2006 – 2010, consider the Plan of ActionEnvironmental Residual Water Management must like objective “asegurar the suitable oneenvironmental handling of residual waters, from the increase in the treatment andquality of residual waters, the construction of Plants of Water TreatmentResidual and the disposition of the solid remainders of the systems of treatment ofwaters residuales”.1,3 CHARACTERISTIC OF THE LOCALITY1.3.1 Location and extensionPlanta de Tratamiento de Residual Aguas Taboada, will be located in a zoneadjacent to the Taboada beach, near the confluence of the avenues Néstor Gambeta,Faucett and freeway to Window, in the district and Province of the Callao, close to the AirportThe International Jorge Chávez. To see P-01 Figure.The area of influence of the project is limited by the superior part of the city and byinferior part with the sea, by the North by the river Chillón and the South by the avenues Stroll ofthe Republic, Grau and Nicholas Ayllón until the District of Santa Anita.The served areas are conformed by 8 areas of drainage, which include an areatotal of 37.176 hectares, according to is in Picture 1.1. The waters served asthese areas of drainage will come together towards the plant of treatment projected in the beachTaboada, for which it is counted on a land of property of SEDAPAL of 10hectares.Picture 1.1Areas served according to drainage areasof the Sub Taboada systemSource: Adapted of the Closing report Technical File “Interceptor Norte”Area of Drainage Area (It has)COSTANERO 1.929,50NAVY 2.505,69ARGENTINA 1.697,23Not 19 1.863,24CENTENARY 2.407,33Not 6 8.618,46BOCANEGRA 1.142,10COMMAS - CHILLON 17.012,60TOTAL 37.176,15PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO4Partnership Collectors of the Callao, 2004, with base in information of the EquipmentHarvesting and Final Disposition – SEDAPAL.PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO5Graph 1.1Lima metropolitanDistrict of the CallaoPTARTABOADAPROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO6P-01 PLANEPROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO71.3.2 ClimatologyThe districts involved in the project are located mainly in the zonenorth of Lima, where the climate is tempered, without great rains nor cold intense.The temperature average in the months of summer (of half-full of December to half-fullof March) it is of 25 degrees Celsius, whereas in the winter (of July to September)the days are gray, cloudy and with enough humidity. The temperature average fluctuatesbetween the 12 and 15 degrees Celsius.1.3.3 AltitudeMost of the area on watch smoothly descends towards the west and the south towardsRímac river and the ocean. The limits current above of the pick up river basins arehills that limit the city by the north and the east. To the north of the Rímac river, the landit elevates gradually from the level of the sea; towards the Southeast of the Callao, beachesthey finish in cliffs of about 30 to 50 meters of height. From the top of thesecliffs, the land rises inland in direction. In the zone where they will come togetherwater-drainages, towards the PTAR, the topography are flat, fluctuating between 3 and 7 m.s.n.m.1.3.4 Routes of CommunicationThe zone of the project is located to 1 km of the Slumses SaritaColony and Acapulco, adjacent to the freeway to Window by which it is acceded to the zone.Also the access through the avenues Néstor Gambeta is possible, Faucett, indistrict and Province of the Callao.1.3.5 Grounds, geology and sismicidad1The grounds in the area on watch are the result of the frequent flood and erosioncaused by the rivers Chillón and Rímac and they are affected by these. The superficial layerof the ground generally she is thin and underneath her are muddy sand layersand stony. Great areas with conglomerates of arenaceous such as hills existinteriors and the cliffs from the coast to the Southeast of the Callao.The zone costeña of Peru is a seismic area extremely associated with the subduction ofthe plate of Is born under all the coast the west of South America. The great earthquakes of1940, 1966, 1970 and 1974 caused enormous damages in the metropolitan area of Lima. sandy alluvial and deltaicos grounds under the coastal areas near Lima aresusceptible of liquefaction. During the earthquake of 1970 (of a approximate magnitudeof 8,7 degrees), many parts of the city experienced liquefaction.1.3.6 Pluvial PrecipitationIn the districts of Lima and Callao there is very little rain: the annual precipitation average isof less than 20 mm.1.3.7 Existing servicesPotable water and Sewage systemThe service of water and sewage system is administered by SEDAPAL. The zone ofstudy, conformed by 27 districts of Lima and Callao (some in its totality, otherspartially), it counts on a cover of potable water and Greater sewage system of 65 %.information on these services is provided in item 2.1.21 Emitter and Feasibility study PTAR Files North. Parsons, 2000PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO8Electrical EnergyOn the other hand, in the districts that conform Lima, the mains is partly undergroundand partly aerial, they have definitive character and in some cases in remote zones it isprovisional. The public service of electricity is provided by the following onesgenerating and distributing companies:Picture Not 1,2 Companies of ElectricitySEDAPAL has an Agreement with Company EDEGEL by the use of waters ofMarcapomacocha project - Mark III, also has to the date contracts of Purchase ofElectrical energy to Distributing Companies EDELNOR and LIGHT Of the SOUTH.It will be counted on energy available in the land destined for the plant of treatment atraverse of the extension of the line of 10 KV on the 50 ms to the east of the Av. NéstorGambetta and approximately 350 ms to the north of the intersection of the access road tolandTelecommunicationsIn the city of Lima four (4) companies of Fixed Telephony and Movable Telephony and 28 existcompanies of telephony to Long Distance. Between these companies we have to the CompanyTelephone, Movable Communications of Peru, Nextel and Tim.As far as fixed telephony in Lima and Callao to December of the 2005 58% of the populationit counts on this service, 23% with cellular telephone prepayment and cellular 7% with normal.To December 2005, the population has itself in the Zone of Lima that counts on othersservices like TV. Cable is 31% and with the service of connection to Internet 7%, beingLima Modern the one that presents/displays he but high percentage with 61% and 37%. In the Zone of Lima69% have some service and in Lima Modern single 5% of the population do not count onno service.1,4 ANTECEDENTSThe unloading of residual waters in the water bodies has been one ofmain problems in the city of Lima. In 1996 only the 1,5% of the water-drainagescollected, they were treated in treatment plants. In 2000 east percentageit increased today to 4,3 and thanks to the efforts made by SEDAPAL, the percentage oftreatment of water-drainages reaches 9%. Nevertheless, still 90% of residual watersthey have its final unloading in the sea without no type of treatment.In the Masterful Plan of SEDAPAL of 1998, they were identified both like high-prioritymore important subsystems as they are the Chira (South Lima) and Taboada (North Lima),considering in both cases the construction of a plant of treatment and an emissarysubmarine. Together these two projects would approximately deal with 90 % watersresidual of Lima Metropolitan, eliminating residual water unloadings the crudedirect to the ocean. At the moment this water remains near the end the Chira and tolength of the North coast of Lima.EDEGEL ETEVENSA EDELNOR LIGHT OF THE SOUTHCompany ofGeneration ofElectricityof LimaCompany ofGenerationOquendoCompany ofDistributionElectrical ofNorth of LimaCompany ofDistributionElectrical ofThe south of LimaPROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO9The Taboada project will substantially reduce the contamination of waters of the coastMetropolitan north of Lima particularly in the zones of the port of the Callao and ofOquendo beach.Studies related to the harvesting subject and final disposition of waters existresidual and the decontamination of the coast of Lima from year 1945 and has deserved inthis time a compatible series of evaluations and adjustments with the urban development ofNorth zone of Lima (area on watch of the Taboada Subsystem) the main studiescarried out they are:1.4.1 Masterful plan of Water-drainages of 1945In the middle of the decade of the 40, the population in Lima was considered of 800.000 inhabitants,and in the that then urban development it was formed by isolated zones. To the southit developed the districts of Chorrillos, Barranco and Miraflores. To the Magdalena West, toThe Northwest The Callao. The Earth use was mainly agriculturist and it did not have oneurban continuity with the Central area of Lima. By the topography and the physical training conditionsescollectors delineated themselves who drain towards the south, the West and North anticipating themselves the unloadingin the sea, the ends of the South zone of Lima and another one in the North zone.The conception of the North Interceptor data of year 1945, in that year, under the direction ofIng. Alfonso Pons Musso, the Ministry of Public Works and the Economy and Public Works, of that then,he prepared a Masterful Plan of Water-drainages, in which two points of emission were designated ofwaters served in the sea of Lima, first located to the North of the Rímac river and the secondto the South of the city.1.4.2 Study of Feasibility for the best disposition of Waters Served as1966When the population of Lima approximately arrived at 2’000,000 inhabitants, it was plannedand a series of primary collectors for the city of Lima was constructed, to coverserved water requirements, between which they stand out Collector no. 6,Collector no. 19, Collector no. 10 and other that drained of This a the West. The designsit executed the Company Greeley & Hansen for the Public Work Supervision andthey were transferred later to the COSAL in charge of the administration ofservices of potable water and sewage system in Lima.In 1966 the company Greeley & Hansen presented/displayed a feasibility study for the best formof disposition of served waters, using the locations indicated in the PlanTeacher of 1945. In this study, the construction of treatment plants was recommendedand submarine emissaries as much for the North point as for the South point of Lima.Also, the construction of interceptors necessary was investigated to transferwaters served to the treatment places, recommending itself again with somesmaller modifications the North construction of 16 Collector no. and Interceptor. Althoughin that opportunity they did not execute any of works recommended in thisstudy, if the lands for the treatment plants were acquired, one in the EndConchán for the South sector and another front to the Hill the Rule, for the North sector.1.4.3 Report on the Disposition of Waters Served as Great the Lima of 1971The report of Binnie & Partners of 1971 on water disposition served in the AreaObject of the Study, reiterates the necessity to unload to the North and the South of Lima. Saidreport recommends that the place of North unloading moves one more to a positionnear the unloading point of the Callao Emitter. The treatment degree was reduced, oflevel recommended by Greeley & Hansen, to a simple separation and crushing ofsolids. In compensation the length was increased significantly of the emitterssubmarines. Also this study reiterates the convenience of the construction of a seriesof new interceptors.PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO10In the feasibility study of Binnie & Partners, the situation of the harvesting was evaluatedof the water-drainages and the final disposition of waters served as Lima. One divided Lima innine areas of drainage These last ones unloaded in different points from the coast towardssea, analyzing itself the unloadings of submarine emissary as much for the South zone as stopsthe North zone. This last one required of an Intercepting denominated fundamental workNorth, determine the proportions with a diameter of 102 inches, that would catch the volumes ofwater-drainages of the primary collectors, costanero, 10, 19 and 6, to lead it towards the beachof the zone of Oquendo2 for its future treatment. Projections became ofrequirements until year 2000.1.4.4 Masterful plan of Potable Water and Metropolitan Sewage system of Lima of1981In the Masterful Plan of 1981 the reinforcing of some primary collectors studied andone projected new primary collectors for the areas of urban expansion. One consideredalternatives to lower the sizing of the submarine emissaries seting outa set of plants of residual water treatments.In the scheme denominated To, 27 plants with small capacities considered;requiring an area of 3609 hectares for a volume of treatment of 2880 l/sIn scheme B a smaller amount of plants seted out, but with greater volumesof treatment.In 1981, it is developed to the Masterful Plan of Potable Water and Sewage system of LimaMetropolitan, developed by Engineering Science, in which the conduction is conceivedof waters served to the North of Lima.1.4.5 Study of Feasibility for the Relocation and Final Disposition of the EmitterCostanero of 1993In June of 1993 the Dr Caesar Ruddy Noriega Pissani develops “Estudio of Feasibilityfor the Relocation and Final Disposition of the Costanero” Emitter;, in which they analyzed themselvesthree alternatives of solution to the harvesting problem, final disposition and treatment ofthe residual waters in Metropolitan the North zone of Lima and three alternatives of outline ofNorth Interceptor. Within the solutions one seted out to project North Interceptor apressure in the section near the airport.1.4.6 Study of Pre-Factibilidad Residual Water Handling in LimaMetropolitan of 1996The Project “Manejo of Residual Waters in Metropolitana” Lima; developed byParsons Engineering Science Inc. International. - PROMAR - BIRF (1996); it developsfinal disposition of the water-drainages of North Lima towards a zone of unloading in the BeachOquendo.1.4.7 Study and Supervision of the Rehabilitation of the Systems of CollectorsPrimary of Lima and Callao and the North Intercepting System of 1998Already in 1998, the Study of Rehabilitation of the Systems is carried out ofPrimary collectors of Lima and Callao developed by the Haskoning Association – AlphaConsult S.A., in which the design of the North Interceptor is made and which Serbian of basefor the licitation of this project.2 Also call Taboada beachPROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO111.4.8 Study of Feasibility of Plant of Residual Water Treatment andEmitter of North Lima of the 2000Later, Parsons Engineering Science Inc. International - U.S. Trade andDevelopment Agency, elaborated the Feasibility study of Plant of Treatment ofResidual waters and Emitter of North Lima (June 2000), in technique was developed andeconomically the alternatives of treatment of the future plant of treatment inOquendo Beach.1.4.9 Integrated systems of Treatment and Residual Water Use in AmericaLatin: Reality and Potential – Study of Viability of San Agustín, Callao,Peru. CEPIS, 2002.In the 2002 Pan-American Center of Ingenieri'a Sanitaria (CEPIS) makes a studyin the zone of San Agustín, whose purpose is to take advantage of residual waters the CollectorNot 6 for irrigation of agricultural zones, considering the construction of lagoons ofstabilization and the use of a system of irrigation by aspersion. Withinmain obstacles identified for the viability of this project, are mentionedNorth Intercepting project, whose exposition considers the derivation of Collector Not 6towards the North Interceptor and its later treatment in Planta Taboada and dispositionend in the sea by means of a submarine emissary.1.4.10 Profile and Study of Feasibility of the Project Construction of the InterceptorMetropolitan north of Lima both of the 2004At beginnings of year 2004, SEDAPAL elaborated the Profile and the Feasibility study of the ProjectConstruction of the North Interceptor, under the criterion of the National System of InvestmentPublic (SNIP), within as the resaltante one it is the study of population and demand; alreadythat it makes projections of population with criteria more updated so much of the INEI, PlanTeacher of SEDAPAL (1998) and plans of urban development (My House), as welldata necessary makes an analysis of the demand of potable water (to obtainvolumes of contribution to the water-drainage) with updated information of SEDAPAL and the Ministryof Economy and Finances. It is possible to indicate, that although both studies were approved bythe OPI House, the project was not declared viable, finally being exonerated ofSNIP.1.4.11 Stage of Public Licitation National L.P. nonc0002-2003-co-sedapalIn February of the 2003 Service of Potable Water and Sewage system of Lima and Callao(SEDAPAL), it makes the first call to public licitation of the “Interceptor workNorte”. After a long process of selection, the 14 of November of the same year,SEDAPAL, carries out the call with which, the General Management by means of ResolutionNº 938-2003-GG of the 05.12.2003 grants the Good Pro to the Contractor (Partnership Collectorsof the Callao, conformed by the companies Odebrecht Peru Engineering and Construction S.A.C.y Company Minera San Martín S.A.), being made the corresponding publication the 15 ofFebruary of the 2004 in the official newspaper “El Peruano”.Later the 27 of July of the 2004 the contract between the parts subscribes. At the momentthe work is in execution with a 90% of advance.1,5 PARTICIPATION OF INVOLVED ORGANIZATIONS And POPULATION BENEFICIARY1.5.1 SEDAPALIt executes the Project and it must by function administer the area under his jurisdiction and to take care ofthe technical aspects – normative in the matter of water and cleaning for LimaMetropolitan, for which:PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO12• It promotes, it facilitates and it finances the construction of the Systems of Supplying ofWater and of Cleaning• It approves, it supervises and recepciona works of the Systems of Supplying ofWater and of Cleaning• It supports and monitorea the executed projects and to execute, facilitating his transition adefinitive systems.The nature of the project registers in the objectives and policies of cleaning thatit prioritizes the company, which includes the treatment and the final disposition of watersresidual, as one needs in the Masterful Plan for the Potable Water Systems andSewage system for Lima and Callao.At the moment SEDAPAL, before the necessity to put into operation the first stage ofNorth interceptor, in agreement with the IMARPE, comes making a study from dispersionof polluting agents, with the purpose of demonstrating that the unloading of the North Interceptor, witha partial volume of the intercepted collectors, would not cause greater effects ofcontamination to the already existing one in the sea, within the limits conformed by the CollectorCommas – Chillón by the North, and the End by the South. In the Annexed F they appearpreliminary results of this study.1.5.2 Ministry of House Construction and CleaningIt promotes the execution of the Systems of Potable Water supply andCleaning to assure the maintenance and sustainability the services thatit offers the population, it promotes his extension and it assures the safe and sanitary dispositionof the water-drainages, without contaminating the medio.ambiente; in this sense:• It promotes the design and it foments policies that facilitate the application of systems ofcontrol and elimination of you excrete, with technologies that assure definitive solutionsin order to reduce and to eliminate the contamination that the waters generate residual.• It supports the application of treatment processes that guarantee an integral handling andefficient, for the removal of the originating polluting pourings of centerstowns.• It orients the application of solutions with appropriate technologies and competitive cost,considering the costs of investment, maintenance and reinvestment required byadopted solution, that guarantees the operation during the period of life ofProject.1.5.3 Regulating and Normative beingsMain directorate of Salud Ambiental (DIGESA)It is the technical-normative organ in the aspects related to the basic cleaning, healthoccupational, hygiene would feed, zoonosis and protection of the atmosphereIt coordinates the technical-normative frame with the Specialized Institutes, OrganismsDecentralized public of Health, and with Scientific Community National eThe International.In addition, one takes care of the Development of Norms in the scope of his competition, Attendanceand Technical Consultant's office to the external and internal user, Control of the Management, InterventionsSpecialized and Investigation.The Main directorate of Environmental Health, has like direct users to the Directionsof Health, to the companies that they ask for: sanitary rating, sanitary certificatesofficials of export, sanitary registry, sanitary authorization of the system ofindustrial and sanitary domestic residual water treatment and disposition, systemof treatment of potable water, sanitary authorization for the import of remainderschemical solids, substance disinfectants and plaguicidas, sanitary authorizationPROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO13disinfectants and plaguicidas of domestic, industrial use and in public health national econcerned and water disinfectant for human consumption.According to report nonc1158-2006/depa-aprh/digesa, one pronounces that by means ofResolution Directoral nonc0448-2001/digesa/sa, the DIGESA granted the AuthorizationToilet of the System of Domestic Residual Water Treatment by means of processchemical physicist, conformed by different units. This authorization has useuntil the 01.06.06. It is recommended to update this resolution.In Office nonc926-2006/dg/digesa, the necessity is pronounced to deepenstudies to assure the quality the project. Also they show that SEDAPAL does not havepresented/displayed to DIGESA the technical file asking for the SANITARY AUTHORIZATIONOF POURINGS for residual waters. They also reiterate that of not counting onthe due authorization would be transgressing the law. On the matter SEDAPAL, with LetterNonc763-2006-gg, mentions that “existe the possibility that this request of pouringsit is managed, accompanied of a study that demonstrates that the unloading of the InterceptorNorth, with the total volume of all the intercepted collectors or in its defect withpartial volume, would not cause greater effects of contamination to the already existing one in the sea,within the limits conformed by the Collector Commas – Chillón by the North and the Endby the Sur”, reason by which it comes making this study to come to carry outthis request.National council of Medio.ambiente (CONAM)• It proposes, it coordinates, it directs and it evaluates the Environmental National Policy and it approves the PlanNational of Environmental Action, guards by his fulfillment, and executes the actionsnecessary for its application.• He coordinates and he promotes the intersectorial character of the environmental management in charge oforganisms of the national, regional and local level with competitions and functionsenvironmental.The Code of the Medio.ambiente establishes the attributes that must have all pouring ofthe residual waters to the receiving bodies. Through these norms they are designatedframe and conditions that must fulfill the projects that establish the conduction anddisposition from the efluentes to the rivers and the marine coast.The present project adjusts to the requirements that in the matter of the disposition ofwater-drainages of Lima and Callao have formulated CONAM.According to letter nonc0942-2006-conam/pcd, the CONAM, it shows his conformitywith the objectives raised for the first stage of the project (Intercepting North)recommending that the put into operation of this work must be made in strictfulfillment of the effective normatividad. It raises that the institutions that will have to exertthe functions of control of the pouring of waters and the treatment of the remaindersdomestic liquids are the Main directorate of Environmental Health and of the Ministry of HouseConstruction and Cleaning and SUNASS respectively. Also it emphasizesfulfillment with the norms of protection of the marine atmosphere, in charge of the authoritymarine, the DICAPI of the Ministry of Defense. Also, it considers necessary to “incluirthe studies of environmental impact of treatment works and submarine emissary,impacts originated by the pourings of the new collector, for which he is essentialinformation that will be obtained on the behavior of the sea currents, work thatit comes making the IMARPE”.PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO14National institute of Recursos Naturales (INRENA)• It formulates, it proposes, concerta, it leads and it evaluates the policies, norms, strategies,plans and programs for the sustainable advantage of the resources water, ground,wild flora and genetic fauna, resources and for the conservation of the diversitybiological wild.• It permanently characterizes, it evaluates and it watches renewable the natural resources ofway that is viable their conservation, this is its sustainable advantage or hisprotection, according to is the case.The project is oriented to guarantee the environmental conditions average for the habitathuman and to cause the protection of the biodiversity of waters, ground, flora and faunaimmediate to the unloading areas.Institute of the Sea of Peru (IMARPE)• It makes scientific researches of the resources of the sea, the continental waters andthe ecological factors of interaction, and those that prohang the development ofacuicultura.• It makes oceanographic, limnológicas investigations and of the quality of the atmosphereaquatic.• It formulates, it directs, it coordinates, it executes, it supervises and it evaluates the policy of promotion ofinvolved sectors.The project causes the protection of the ictiológicas species in the surrounding sea inpresent unloading points.At the moment IMARPE in agreement with SEDAPAL, come making the study fromdispersion of polluting agents in the Bay of the Callao. The preliminary results of sayingstudy appears in the Annexed F.Direction of Captainships and Guardacostas (DICAPI)They are functions of the DICAPI, to exert the Naval administration, Fluvial and Lacustrine in the scopemarine, fluvial and lacustrine of its competition, through the Captainships and UnitsCoastguard vessel on:The waters of the Marine, Fluvial and Lacustrine Dominion of Peru in the form established byeffective legislation, as well as the islands and the continental socle; All the ships and devicesaquatic that is in the marine dominion, navigable rivers and lakes and those ofnational flag on the high seas or in waters or ports of other countries, without damage ofrespect to the internal laws of the local State and applicable norms of the RightThe International, the foreign ships when they are within waters ofI dominate marine, fluvial and lacustrine nationalTo protect the resources and wealth of aquatic means, establishing the norms and controlsfor the activities in the aquatic scope, considering the cases specially ofcontamination risks.It emits, it proposes and it applies to norms and devices according to agreements subscribed byPeru with international organismsNational supervision of Services of Saneamiento (SUNASS)SUNASS is the regulating and normative being for the Lending Companies of Services(EPS) which it has as a function to approve the Plans Masterful, to establish goals and objectivesin order to guarantee to the users the benefit of the services of cleaning inPROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO15better conditions of quality, contributing to improve the quality of life and health ofpopulation and the preservation of the atmosphere.The favorable opinion emitted by SUNASS when approving the Masterful Plan of Sedapal thatit includes and it prioritizes the sanitary and safe disposition of residual waters, when including in hiscontained the necessary investments for the development of the Taboada Subsystem(intercepting, plant of residual water treatment and submarine emitter), it indicates thatSUNASS has a favorable opinion for their execution.MunicipalitiesWithin the legal attributions of the local governments, she is the one to promote and to facilitatethe development of its communities. Its participation when facilitating is important and to supportexecution of Systems of Communal Water Supplying and Cleaning. Likeit shows later, this project would produce important economic benefits,social and environmental to the population of Lima and Callao in general and specifically toinhabitants of the districts near the area of the project, and therefore, anticipate themselves thatmunicipalities will support their implementation.In effect, the municipalities show to preoccupation and initiatives for conservation ofmedio.ambiente, like the Municipality of San Isidro that comes elaborating a projectof echo-forest park of the zones of the cliff under its jurisdiction, and which is possiblefrom being extended to the other districts.In the case of the Provincial Municipality of the Callao, within the framework of the project they showa great preoccupation due to the lack of information (affirms not to have receiveddocumentation referred to the project).

I CAPITULATE IIIDENTIFICATIONWith the purpose of obtaining updated data of first hand and, they have been madevisits from field to the zone that includes/understands the area of influence of the project thatbasically it is conformed by 27 districts of Lima and Callao (of which somethey take part totally, other partially) whose residual waters will unload toprojected plant of treatment. Visits to works of the “Interceptor have been madeNorte” that at the moment they are being made, as well as of collectors who at the momentthey spill without no treatment to the sea and the river, as they are the Costanero Collector and the CollectorNot 6; also, visits of recognition together with personnel have been made ofcompany contractor that executes the work of the North Interceptor in the zone of the beachTaboada, where one projects to construct the treatment plant.The commercial, operative and financial data has been obtained from the Managements ofNorth, South service, Center, Management of Human resources and Management of Finances ofSEDAPAL.2.1 I DIAGNOSE OF THE PRESENT SITUATIONThe present system of sewage system of the area of influence of the project, leads watersresidual domestic, commercial and as much industrial. Due to the topography, the greater onepart of residual waters is conducted by gravity, with the exception of the low partswhere pumping is required. The cover in residual water treatment is null.The system of residual water harvesting account with an area of total drainage of 22hectares and approximately an of great volume 10 average of m3/seg 3 of residual watersthey unload without no type from treatment to the ocean and the Rímac river, as well as for irrigationof cultures, in the agricultural zone San Agustín, adjacent to the Airport the International JorgeChávez.The primary collectors of the sewage system system who drain to the North of the City ofLima and Callao are the following ones: Costanero emitter (Costanero Collector and Navy),Emitter Commas (Collector Comas and Prol. Chillón), Emitter Nº 6 (Collector Av. Peru Cdra. 23,Av. Peru Cdra. 32 and Base Naval Aero), Centennial Emitter (Collector Moral Duárez,Argentina, Maranga and Ca'mara Unica) and Bocanegra Emitter. To see the Plane Nº 1 whereit shows the location of the present collectors.In the Bay of the Callao and San Miguel, the originating water-drainages are spilled ofCostanero collectors, Centenary (new and old), Bocanegra and Comas-Chillo'n,causing a permanent contamination in the coast. Also, the CollectorCentenary works near its limit which originates problems of atoros in the line.Part of residual waters of the collector Nº 6 at the moment is used byagriculturists of the Agricultural Zone San Agustín, and the other part is unloaded to the Rímac river.An illegal use of the water-drainages on the part of the agriculturists exists who occupy the partlater of the Airport the International Jorge Chávez, creating one of the vectors ofgreater contamination of the zone, in damage of the health of the population of Lima and Callao.According to studies made in this zone, it has been verified that the cultivated productsthey are contaminated, originating damages directly in the population thatit consumes.As it leaves from the solution for the integral cleaning of the North zone of Lima, they comeexecuting works of the North Interceptor, which will lead residual waters tosingle point (in the Taboada beach), where the treatment of waters will take placeresidual, improving the quality of the affluent.3 According to measurements conducted in the collectors, by the Equipment Harvesting and Final Disposition - SEDAPALPROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO20The plant of Taboada treatment will catch residual waters of the North Interceptor, ofComas–Chillón collector and of the Line of Sarita Impulsion Colony (the 3 conformsNorth Intercepting system), as one is in the following scheme.The area on watch of the plant of Taboada treatment, is the area of drainage of the SystemNorth interceptor, the influence area includes the following districts: Miraflores, SanIsidro, Lynx, Santa Anita, Tie, the Agustino, San Luis, Surrounded of Lima, the Victory, SanJuan de Lurigancho, Rímac, Scrub, Jesus Maria, Free Town, Magdalena of the Sea, SanMiguel, the Per it, the End, Bellavista, Carmen of the Legua, Callao, Carabayllo, Commas,Independence, San Martín de Porres and the Olive trees. The drainage area is of 22.08 Has.Altogether: the system of collectors who conform the areas on watch of the project andthe Taboada plant receives the name of “Subsistema Taboada”, which will serve more than 3million inhabitants.2.1.1 Socioeconómicas characteristics of the Populationa) Total and affected populationIn the last National Census of Population and House, has determined that the populationof Lima metropolitan it promotes to 7’765,151 inhabitants, located in 49 districts, ofas SEDAPAL it only administers to 43 districts, with a population of 7’620,000inhabitants.According to the data of the census, to the year 2005, the population in the 27 districts involved inproject promotes to 5’346,888 inhabitants. Of this population, it has been considered that4’334,214 inhabitants comprise of the area of influence of the project, which represents57% of the population administered by SEDAPAL.

The recognition of contamination factors notit accompanies by positive changes in the intrafamiliar sanitary practices. evidence that the knowledge still does not obtain a sufficient internalization ofrisks in the health, which affects the incorporation of practices unfavorablyadapted of hygiene.• Positive the previous experiences influence in considering the hygiene like a valueindependent of the poverty. In these cases, the care of the hygiene isrelated to an increase of the personal and familiar self-esteem.• The hygiene practices are seen remarkably affected by the high costs thatit demands the use of nonconventional water systems and cleaning. To have waterhe is more expensive for the poor and extremely poor families whom they do not haveservice of SEDAPAL for which yes they have it.• The practices of hygiene in the use of the latrine are in favor conditional of hisinadequate construction and little preparation. The preparation as wellit is determined by the little access to information, by the levelssocioeconomic of poverty and it carries far poverty and by the little commitment ofmen in the development of adapted practical of familiar hygiene (they are those thatthey assume the tasks of construction and repair of buildings)• The use of open field is explained by the expectation to count soon on the systemconventional, with the cost of materials, with time that requires the constructionof the latrine and with the rejection to “suciedad” by the presence of lees and latrine tointerior of the house.• The practice of the washing of hands is inadequate by the ignorance of the techniquecorrect and by the little and superficial use of the soap. The found conditions nothey favor the washing of hands. The majority has a single preparationfor it, for the washing of the familiar menaje, the washing of clothes and the place where it receivesthe water. The limited water availability, the time that implies the spare part of thisresource and the little presence of the soap and the towel, is considered conditionsunfavorable.4 the study was made in Slumses and Young Towns of the different districts from Lima.PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO23• The practices of hygiene related to the contamination are unsuitable. One ofthe few suitable practices of the population are the water boiled one.• The suitable practices of hygiene that avoid the food contamination arelittle incorporated in the population. Were uncertain, accessible devicesto the vectors and domestic animals. The washing of the familiar menaje becomesusually single with water.• The factors that influence in the contamination are the free animal raisingdomestic, the presence of flies, the little proportion of knowledge onwashing of hands, the food consumption without washing, the clean water nonuse,lack of hygiene in the latrines, among others.• The population does not perceive the tie aspects with the hygiene water (practical,lack of hygiene, lacks of the washing of hands at key moments) like the factormain associated to the infantile diarrea.d) HouseBeing that the influence area represents 60 % of the population of Lima almostmetropolitan, for the present study the characteristics of the city will be considered ofLima.In the city of Lima, of the total of houses, 79% correspond to independent houses,10% to departments in buildings and 5% to house improvisada/choza; In the same onelayer, the houses in the fifth and houses in vicinity are of 4% and 2%respectively.

Parsons, 1999 – 2000PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO29According to analyses made by the Equipment Evaluation of Quality of SEDAPAL, in Octoberof the 2004, the DBO concentrations have increased significantly, liketotal coliformes, had mainly to the increase of the population. In the Annexed Bit shows the document with which the Equipment Evaluation of Quality emits the results ofthe respective analyses.In picture 2.11 the results of the made analyses are the water-drainages ofthe main collectors of the Taboada subsystem.Picture 2.11Results of analysis of water-drainages of the main collectorsTaboada Subsystem, 2004Source: Equipment Evaluation of Quality – SEDAPAL, 2004Although probably the points of sampling of the work made by SEDPAL in the year2004 they have not been such that those of Parsons in 2000, could be asserted, thatthe laid-down load in the water-drainages has been increased, this is related directly tothe growth of the population and the consumption restricted in some zones, speciallyat the time of low water. The DBO, for example, was in average in 2000 of 230 mg/l,having itself elevated to more than 300 mg/l in 2004. Also, the total coliformesthey have been increased in the water-drainages of each one of the analyzed collectors.According to the first characterization of residual waters in each collectormade by Parsons (2000), we could say that according to the average concentrationof Total DBO and Coliformes, these water-drainages could be considered of concentrationAverage, according to the categorización Metcalf & Eddy, whereas in the second case, withSEDAPAL results (2004), the categorización would be of Average - High. To see Annexed C.d) Investigations of the quality of the water of seaAccording to the Feasibility study of PTAR and emitter of North Lima made byPARSONS, in the spring of 1996 and summer of 1997, took place an extensive study ofquality of the water of sea in front of Lima. Samples in 58 stations took shelter, wherethe depths of the water varied until the 65 ms. Altogether near 8000 samples ofwater of sea was gathered and analyzed. The following parameters were analyzed:Physical parametersTemperatureSalinityTransparencypHChemical Parameters:Dissolved oxygen (in the water column)Phosphates (in the water column)Sulphates (in the water column)Parameters Unit ofmeasurementHour 11:30 a.m.Costanero CollectorHour 12:25 a.m.Centennial CollectorHour 12:40 a.m.Collector CommasHour 1:00 p.m.CollectorBocanegraHour 2:35 p.m.Collector Not 6pH Without unit 7.83 7.59 7.62 7.96 7,67DBO mg/l 340 305 340 380 380Coliformes total NMP/100 mililiter 1.7 xs 108 1.1 xs 108 8 xs 107 1.7 xs 107 1.7 xs 108Coliformes termotolerantes NMP/100 mililiter 1.3 xs 108 3 xs 107 8 xs 106 2.7 xs 106 3 xs 107PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO30Hydrocarbons (in sediments)Heavy metals (in sediments)Biological Parameters:Coliformes totalColiformes fecalesSalmonelasVibrio RagePhytoplanktonZooplanctonThe study revealed the following conditions:The temperatures of the superficial water varied from 16,6 to 22,5 oC. The superficial salinityit fluctuated between 34,75 and 34,90 parts by thousand.The solids suspended in half of the Bay of Miraflores showed values of up to 34 mg/l.In comparison, the water of typical sea has a solid level suspended of near 20 mg/l.The transparency of the water was below the normal thing in all the coastal areas, withlower transparency of 0,3 m (according to obtained measurement using a Secchi disc) nearmain unloading points of the Chira and Comas. This condition affects seriouslyprimary production of phytoplankton and can have adverse consequences for the marine life ingeneral.The concentrations of Biochemical Demand of Oxi'geno (DBO), fluctuated between 1,7 and 1,9 mg/l,as he is higher than the water found thing typically of sea noncontaminated, and is indicative ofexternal income of organic matter of the water-drainage.The dissolved oxygen concentrations superficial fluctuated between 1,4 and 8,3 mg/l.Near the mouths of the rivers, as high values of pH were registered as 10,27,as he is hostile for the marine life.The superficial phosphate concentrations fluctuated between 0,53 and 11,8?g-at/l, whereasnitrate reached 6,55?g-at/l. Sulfur fluctuated between 0,27 and 22,8?g-at/l.The organic matter in sediments fluctuated between 1,38 and 14.4%.High levels of copper, lead and mercury through all the North portion were found ofstudy area, particularly in sediments. The copper was measured in levels of up to 230mg/kg, and the hydrocarbons reached up to 26,2 mg/kg of dry weight.Of particular interest they are the results of analysis of total and coliformes coliformesfecales in superficial waters front to Lima. The information, summarized in the PicturesC1 and C3 of the Annexed C, and illustrated in Figures 1,1 and 1,2, reveal that they wereparticularly high levels of coliformes next to the mouths of the Rímac River andin End the Chira.According to the obtained results, it can be observed that in many of the casesparameters exceed the Peruvian norms, as much in waters Class IV like class V.These norms appear in the Annexed C1PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO31Figure 1.1Space distribution of total coliformes in superficial waters of the Pacific Ocean duringthe Spring of 1996, expressed in MPN/100 mililiterPROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO32Figure 1.2Space distribution of fecales coliformes in superficial waters of the Pacific Ocean duringthe Spring of 1996, expressed in MPN/100 mililiterPROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO33e) Potable water coverThe potable water cover of the population in the area of influence of the project thatit counts on domiciliary connection is approximately 61.3%.In the zones where the population lacks the service of potable water throughdomiciliary connections, the supplying takes place generally by means of truckscistern which they distribute to the water to the houses, storing itself this one in deposits orcisterns located in frontis of property. Also, zones exist thatpublic embastecen through pylons.f) Cover of sewage systemThe cover of the sewage system, related to the population that counts on connectiondomiciliary, it includes/understands approximately to the 61,3% of the population of the 27 districts thatthey conform the project. The rest of the population corresponds to those without no serviceof sewage system or that uses sépticos latrines or tanks.g) Treatment and disposition of residual watersThe present system of sewage system of the area of influence of the project, has been designedin order to lead as much domestic residual waters as industrialists. Due totopography, most of residual waters is conducted by gravity, with exceptionof the low parts where pumping is required. The cover in water treatmentresidual she is null.The residual water system account with an area of total drainage of 22 hectares andapproximately an of great volume average of 10,4 m3/seg of waters residuales5 unloadswithout no type from treatment to the ocean and the Rímac river, as well as for irrigation ofcultures, in the agricultural zone San Agustín, adjacent to the Airport the International JorgeChávez.The primary collectors of the sewage system system who drain to the North of the City ofLima and Callao are the following ones: Costanero emitter (Costanero Collector and Navy),Emitter Commas (Collector Comas and Prol. Chillón), Emitter Nº 6 (Collector Av. Peru cdra 23,Av. 32 Peru cdra and Naval Aero Base), Centennial Emitter (Collector Moral Duárez,Argentina, Maranga and Ca'mara Unica) and Bocanegra Emitter. To see the Plane Nº 1 whereit shows the location of the present collectors.In Picture 2.13 one is to information on the emitters and the present disposition thatit corresponds to each one of them.Unloadings without treatment to the sea and the Rímac riverAt the moment, great part of the water-drainages generated in the North zone of Lima,they unload without no treatment in different points from beaches of the Bay of the Callaoand in the Rímac river, causing a permanent contamination in the coast. Also,Centennial collector works near his limit which originates problems of atoros inline.The collectors Commas, Costanero, Centenario and Bocanegra unload directly tosea without any type of treatment. Also, Collector Not 6 unloading directly inthe Rímac. river (to see photos 2,1 and 2,2).5 According to measurements made by the Equipment Harvesting and Final Disposition of SEDAPAL.PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO34Derivation of water-drainages towards Agricultural ZonesAn illegal use of the water-drainages on the part of the agriculturists exists who occupy the partlater of the Airport the International Jorge Chávez, creating one of the vectors ofgreater contamination of the zone, in damage of the health of the population of Lima and Callao.Also, from the point of view of security, the aerial transport is affected bypresence of birds in the Airport the International of the Callao, the same ones that are attractedby the nutrients that are in the free unloading that it makes in the environs.Picture 2.12Area of Drainage, Lengths and Final Disposition of the Main onesPrimary collectors in the Area of Influence of the ProjectSource: Management of Production - Equipment harvesting and Final Disposition – SEDAPAL, May 2006The unloading of the collectors in the cliff produces erosions that make be in dangerhouses located in the Av.

Although a new one has been constructed alreadysystem from unloading to the sea, located 300 ms towards the Callao, this one does not work by oppositionof the settlers, afraid of which the bad scents affect them.Photo 2.1Unloading of the Collector Nº 6 to the Rimac RiverNOTE: IT IS OBSERVED CHILDREN BATHING IN WATERSRESIDUAL WITHOUT MEASURING RISKSEMITTING disposition Type of Disposition Length (km)Projected End Present Treatment 2005COMMAS No Sea - Callao 89,730COSTANERO No Sea - San Miguel 79,185Nº 6/1 No Rímac River/channel of irrigated land 62,870CENTENARY No Sea - Callao 87,686BOCANEGRA No Sea - Callao 5,042CONDEVILLA (*) No River Rímac 9,443* Incluído in the area of drainage of the Nº6 emitterINTERCEPTORNORTHPROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO35At the moment, for this susbsistema, one comes executing the “Interceptor work Norte” thatas its name indicates it intercepts the Costanero collectors, Argentina, N° 19, N° 06and Bocanegra to lead its water-drainages towards the future plant of treatment located inthe ex- ones I found Taboada, and thus to avoid the contamination of the medio.ambiente andconsequences that this implies on the human health and the natural surroundings.The water-drainages of the collector Commas will be joined in the camera of union located beforepresent unloading of the collector Commas and will be turned aside towards the plant of Taboada. Forcase of the Centennial collector, the water-drainages will be taken towards a future station ofdenominated pumping Sarita Colony that will be located near the present unloading pointof this collector, later to be impelled until the treatment plantTaboada water-drainages.h) Effects of residual waters in the receiving bodyEffects on the human healthThe human contact with residual waters not treated as in the case in the CoastSailor mainly of the Callao can be in diseases such asgastroenteritis, rage, tuberculosis and others enfermedades6. The causes of thesepathogenic diseases include the bacterium or virus whose presence is detected fromthe indicators such as the bacterium commonly found in the intestinal region ofmammals such as the fecales coliformes, fecales Escherichia coli, estreptococos,bacteriophage, Giardia lamblia, and intestinal eggs of Escherichia coli, estreptococosfecales, bacteriophage, Giardia lamblia, and intestinal eggs of helmintos.The problem of the contamination of the Peruvian sea has been matter of study and someinvestigations. In an article of the Caretas7 magazine, “el sea of the Callao is, of distant spot,more contaminated of the Peruvian Coast, due to the drainage of the collectors Commas,Centenary and San Agustín. According to the Institute of the Sea of Peru (IMARPE) in its watersheavy amount of fecales coliformes, metals, oils and hydrocarbons of petroleumthey surpass the limits established by the General Water Law. On the matter, the present onedirector of Oceanography of the IMARPE, Ing. Guadalupe Sanchez, notices that betweencenter and the north of the bay, has registered anoxia or low levels of oxygen, which isdiminished the temperature in that zone with relation to the rest of the bay, affectingseriously the ecosystem marino”. The same article indicates that the limits of the district “enof the Per it with San Miguel, to the height of the Military School Leoncio Prado, the collectorCostanero appears in the low part of the inhospitable cliff and expels to the beach a spurtfrothy. Also, it informs that this nauseous place is visited by fishermenartisan, therefore, some of the fish that arrive at the table from the Limeans, are hadfed with proteins on the coliformes fecales”.Of another side, in 1995, the OPS/CEPIS publishes the study “Impacto of the Atmosphere in the Healthof the Population Involved in the Treatment and Use of Residual Waters in Lima andCallao”. It must like objective identify the environmental risks and the effects in the health ofthe people involved in the use and handling of residual waters in Lima and Callao.With regard to the agricultural zone of San Agustín, the Environmental Evaluation foundthe following results: The bacteriological quality of the irrigation water presents/displays a stopnumber of fecales and total coliformes 1,6x108, 3,8x108, respectively; it existspresence of Salmonella, also presents/displays a high concentration of parasites.As far as the bacteriological and parasitológica quality of the cultures, the fecales coliformesthey exceed the maximum limit of less than three units stipulated by the normsnationals; the amount of parasites in products exceeds the quality demanded byconsumption norms. In general, one concludes that no evaluated vegetable must beconsidered apt for the consumption.6 Project of Handling of Residual Waters of Lima Metropolitan: Norms of Environmental Quality, by Parsons, Julio19967 Magazine Masks “Las Cataracts of Lima: Veraneantes and marine habitat in danger. It is urgent to stop the contaminationcaused by the eight collectors in charge to spill the water-drainages from Lima to mar”. Lima, 25 of January of 2001PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO36Hidrobiológicos effects on the medio.ambiente and resourcesThe pouring of residual waters without treatment has lead to the physical deterioration andecological of the marine coast that has a considerable importance within the development ofmany human and economic activities such as recreational activities and ofecoturismo, the acuicultura, and fishes artisan or commercial.In the Peruvian Sea two main ecological dominions exist: pelago and the bentos. bentos are the part that is on the bottom of the seas, there exist diverseorganisms that depend on him to introduce themselves, to pay attention, to walk or nothing on him andmainly to find its food. Pelago is constituted by all the beingsliving of the free water where they float and they swim. The pouring of residual waters withouttreatment affects of negative way the ecological resources.The contamination of the marine coast deteriorates the alive resources, increases the risk stopsthe human health and such are an obstacle for the development of the marine activitiesas the fishing and the recreation. Also the contamination destroys the coastal bottoms ofreproduction and along with the excessive fishing reduces to many species comerciales8.Area of recreationThe Direction of Environmental Health of the Ministry of Health comes analyzedpermanently the levels of contamination of the Peruvian sea. Thus, for the period1997-2001, are reported that the levels of contamination of some beaches of the scope ofproject (Beaches: Marquess, Oquendo, Acapulco, Carpayo 1, Carpayo 2, Brave Sea -Per it, San Judas Tadeo and Marbella) they present/display important signs of contamination ofits waters, being described like very bad (over 4000 coliformesfecales/100ml), with the consequent danger for the human health. Of the information ofannexed it is deduced that in Lima Metropolitan, a 8% of beaches present/display a qualityvery bad, a bad 18% (over 1000 to 4000 coliformes fecales/100ml) and 45%to regulate (over 500 to 1000 coliformes fecales/100ml).Devaluation of the estatesAccording to study PROMAR9, the unloading of residual waters without treatment it hitsof negative way in the value of the estates located until at least 300 meters ofthe coast and throughout the affected coast. This devaluation is from the impactsnegatives discussed previously on beaches, the natural resources of the sea, andhuman health. Consequently, the economic use of the estates lowers or it is reducedcompletely and therefore they devalue.The estates can be used by commercial aims (i), such as businesses forpeople who frequent beaches, (ii) productive, such as the fishing, (iii) tourist, suchlike the hotels and restaurants and other businesses oriented to the tourists, (IV)residential, for house, (v) public, like maintenances and areas of recreation forpeople who frequent the area. As the contamination of the coast limits or paralyzescompletely the activities, the value of the estates diminuye drastically due toreduction of its economic use.i) Effects of residual waters in the irrigation of agricultural zonesThe watered agricultural products with residual waters without treatment see affectedsignificantly its sanitary quality, with the consequent danger of contamination ofpopulation by the consumption of these products, mainly if they are consumed crude and withlittle hygiene.8 Project of Handling of Residual Waters of Lima metropolitan: Norms of Environmental Quality, by Parsons, Julio19969 Study of Environmental Impact of the PROMAR, by Nippon, Joseguido Sekkei-Parsons, March of 1998PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO37The OPS/CEPIS/IDRC (1990) “Evaluación of Risks for the Health by Uso de Aguasresidual in the Agricultura”, it investigated microbiological and toxicológicos aspects of reusoof residual waters in four zones of study: Cieneguilla, San Juan de Miraflores, SanMartín de Porres and San Agustín. In these zones samples for the respective ones were takenanalysis. The different vegetal products, in their great majority vegetables, were classifiedin agreement with the position of the eatable part in: under earth, earth flower and high stem.The bacteriological results of this investigation showed that the products thatthey grow to earth flower, more were contaminated with fecales coliformes, becausemicrobial density is greater in the surface and diminishes with the depth of the Earth.They follow the vegetables to him that grow under earth and finally, those of high stem, that they receivesolar radiation. The differences in the bacterial population density between productsirrigated with different type from water, it was demonstrated in the smaller sanitary quality thanthey presented/displayed originating vegetables of the zone of San Martín de Porres and the Callao.San Agustín sp. presented/displayed the greater percentage of presence of Salmonella was registered91.1% of samples contaminated by protozoarios and helmintos of sanitary interest invegetables irrigated with crude residual waters, whereas the irrigated ones with waterstreated (lagoons of San Juan) they reported 31.1%. in addition, was verified that of allanalyzed species, the lettuce irrigated with crude waters presents/displays the highest rate ofparasitic contamination (100% of the samples), in contrast to reported 50% withtreated water irrigation. Also it was observed that of the three zones, San Agustín reportedthe greater percentage of parasitic contamination in vegetables.In 1996 the OPS/CEPIS/IDRC published “Estudio of the Atmosphere in the Health of the PopulationInvolved in the treatment and residual water use in Lima and Callao” for whichthey selected three areas of study: the lagoons of stabilization of San Juan ofMiraflores, the agricultural zone of San Juan de Miraflores (bordering to the lagoons) and the areaagriculturist of San Agustín. The study had like objective to identify the environmental risks andthe effects in the health of the people involved in the use and handling of watersresidual of Lima and Callao. The smaller sanitary quality of products was confirmedoriginating of San Agustín in relation to the irrigated ones with treated residual watersin the plant of San Juan. The medical clinical result determined rates average ofaffectation to the health in parasitism (15.1%), diarreas (9.5%), hepatitis (8.7%), tifoidea(18.7%) and rage (6.8%) substantially greater in San Agustín for the two decadesanalyzed (1978 – 1987 and 1986 – 1996). concluded in addition that the manipulation ofresidual waters, the nonpotable water consumption and the inadequate disposition of you excretethey are the main factors involved in the pathological and indicating antecedentsepidemiologists of the studied population.Source: Study of Viability of San Agustín, Peru.

Also at times of avenue the broken Jicamarca (right margin) andbroken Appearance (left margin) they contribute in the increase of the volume of the Rímac river.The pick up of waters of the Rímac river is made through a system of: 01 BarrageMoving body and 02 Bocatomas, in which they conduct the operation of roughdressing, that consists ofpresent elimination of shrubs and diverse materials in the water those that are retainedin the grids by where the water for its treatment enters.The Bocatomas m.s.n.m is to 265.21.The movable barrage consists of 5 sliding floodgates that move on rollers of 9.15m. of high length by 2.74m of each one. This infrastructure was constructed between the years1965 and 1967.The capacity of pick up of Bocatoma 1 is not of 15 m3/s and the pick up capacityof Bocatoma 2 m3/s is not of 20The Bocatoma Not 1fue constructed between years 1965 and 1967, whereas the Bocatoma2 were not constructed between years 1993 and 1994.Plant of treatment Chillón waterPlanta de Tratamiento “Chillón” it is part of the system Optimal “Aprovechamiento ofSuperficial and Underground waters of the Chillón” River;, also denominated ProjectChillón, which was constructed, and at the moment operated by Consorcio AGUA AZUL S.A.,under system BOT, according to the Contract of Concession subscribed with the Ministry ofPresidency, today Ministry of House, Construction and Cleaning, in its quality ofConcedente.The period of the Concession is of 25 years and has the commitment to provide 1 m3/s intime of low water of the river Chillón and 2 m3/s at time of avenues.The water produced by the Concessionaire, is sold in block to SEDAPAL to a tariffdefined proposal and in its economic supply with which it was winning in the process fromselection. This water later is distributed by SEDAPAL to the users of the conenorth.The plant is located in the Punchauca sector, district of Carabayllo, province anddepartment of Lima (height of km 27 of wagon Lima to Sings)Underground WatersIn the 24 districts that comprise of the project it distributes to a total of 8’675,305 m3 ofpotable water to the month. It is counted on 152 wells in operation, 14 in repair, 38in reserve and 51 wells that correspond to conjuntivo use. The complete information onvolumes, number of hours of pumping, etc. D1 Picture is in Annexed the D -.System of primary DistributionThe city of Lima is supplied by means of first pipes with diameters between 72” and14”, it includes/understands the Return of the System of Distribution which implies the separationof the system in isolated zones denominated Sectors within which it canto control the level of the service to the user through the regulation of the entrance volume andlevel of the pressures by means of system SCADA, according to pre-established plans of operation,or at level of sector or sectors that conform a district.The System of Primary Distribution, counts on 5 main main lines thatthey when coming out initiate of Planta the Culvert:PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO39- First Culvert – Commas, complemented with Planta de Tratamiento Chillón.- First Culvert – Villa El Salvador- First Culvert – Center- First Culvert – The Menacho- First Culvert – The MolinaFirst Culvert – Commas:The Line of First conduction Culvert – Commas supply to the districts of the North zoneof Lima: Independence, the Olive trees, leaves from the district of Commas, Rímac, San Martín ofClubs and Bridge Stone, complemented with waters originating of Planta ofChillón Treatment. This matrix begins in Planta de Tratamiento the Culvert (PlantN° 2) located in the district the Agustino and arrives until the Camera of Rebombeo CR-115 inthe district of Commas, with a length overall of 22 km and with intermediate diameters between64” and 24”; the line is of Prestressed Ductile and Concrete Iron, leading at the momentapproximated volume of 5 m3/s in its section of 64”.It has a storage unit, reservorio R5 of 50.000 m3 of capacity, thatit supplies to the indicated matrix exclusively.It gives service to the matrix of Rímac reinforcement that begins in the crossing of the AvenuesPalace and Tarapacá until the crossing of the Habich Avenue and the Pan-American North, with oneinterconnection to the line Commas in the corner of the avenues Habich and Tupac Amaru; toend of this matrix is branched off in two great lines:Matrix The Olive trees: that it supplies to the 86 sectors of the 79 to corresponding to the districtsof the Olive trees and part of San Martín de Porres and to the corresponding sectors inFirst Takings Valley.Habich-Callao Matrix: that it supplies to part of San Martín de Porres and reservorioPark the International, as well as directly to the sectors of high pressure (100,101, 102 and 103), and to the First line Culvert – Center, waters under the ERP Argentina.From the beginning of theAtarjea-Comas line to Station CR-115 they existmain being but important derivations the derivation of Zarate – SongGreat 36” that it supplies to the district of San Juan de Lurigancho and the Habich derivation 36”that it supplies to the district of San Martín de Porres. The 90 pressures vary from 110 to mcain the sections of Habich – Commas for a normal supplying towards the zonessupplied by the other derivations. This system distributes by gravity to severalsupported reservorios from 750 to 1600 m3, in the 10 remaining derivations (8” to 12”) tolength of the Habich section – Commas. In this passage the zones of Urb. Palao are supplied,Engineering, Tahuantinsuyo, Independence, etc., in addition to several EstablishmentsYoung humans and Towns.The supplying to the North zone is complemented, from year 2002, with watersof Planta de Tratamiento Chillón (administered by the partnership Blue Water undercontract BOOT), that in one 1° Stage supplies by means of a well battery to the MatrixChillón – Commas, benefitting directly to the districts of Carabayllo and Comas,holding a concealed knife to the existing matrix (Habich - Commas) to the height of the CR-115. 2° Stageit supplies to the districts of Bridge Stone, Cove and Santa Rosa.First Culvert – Villa El Salvador:The line of First conduction Culvert – Villa El Salvador supplies to the districts ofSouth zone of Lima. Part of Planta de Tratamiento the Culvert (Plant 2) located indistrict the Agustino and arrives until Villa El Salvador with intermediate diameters between 72” and24”; it has an approximated length of 20 km, is of concrete prestressed and it leadsat the moment an approximated volume of 5 m3/seg. in its initial section of 72”.PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO40Throughout the old matrix 4 valves of main line exist, San Francisco of56”, Race course of 40”, Spring of 42” and Próceres of 36” respectively.A derivation to the height of the Av exists. The Quechuas (district of Ties) where beginsCanada Matrix – San Luis who supplies to the sectors included/understood partly of Ties, SanBorja, San Luis, part of Surco and Surquillo. This Matrix feeds the reservorios Heroesof La Paz (30.000 m3 which supplies to the districts of Barranco and Chorrillos as well) andSan Borja (15.000 m3 which supplies to part of Miraflores), also feeds the lineFirst Average Furrow supplying to the sectors included/understood in the district of Santiagoof Furrow.A line of reinforcement exists that leaves from a joint for the height of the Ford/Vía streetEvitamiento (district of Ties) and follows compares to the Old Line until the height of the bridgeSpring, line of ductile iron with diameters between 72” and 64” without derivations; to the heightof the bridge Spring (street Cristóbal de Peralta) it is interconnected by means of a valve of36” to the Old and simultaneously continuous Line the following section of the First Culvert – YOU SEE 2°Ductile iron stage with diameters that vary between 64” and 36” that it supplies by means ofderivations to the following reservorios: RÅ, R3 (Pamplona), R2000, R10A, R10C, RTN,R9, CR9 and to reservorio the Tablada (16.000 m3) that supplies to the sectors of the district ofVilla El Salvador.From the beginning of the Old Line to the Próceres Station 10 derivations existmain being but important the derivation of Spring 24” that it supplies asome sectors of Santiago de Surco, part of San Borja and Surquillo with a volumeapproximated of 1,05 m3/s. The pressure for a normal supplying for this line is of28 mca.The volume of arrival to the Station Próceres (km 12 old the Pan-American South, Urb.Amauta in San Juan de Miraflores) is of 0,60 m3/seg..
