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).
