Technical Report 8 (translated)

Protection against the corrosionThe methods of protection against the corrosion are based on the material of the pipe andmedio.ambiente. The system of protection against the corrosion in the pipe must be effectiveduring the life of 75 years of the project. The alternatives of protection against the corrosionthey include passive or active systems of cathodic protection (current printed),effective dielectric covering, and a cement mortar armored deck.The protection against the corrosion for the TCR is satisfied generally by means of the provisionof concrete adapted on the steel surfaces. The steel reinforcement within the pipeit will be covered by a minimum of 40 to 50 mm with concrete, protecting effectively to the steelagainst the corrosion by the efluente or the water of sea in the course of the 75 years of life utility.In some emisarioes of TCR has been deterioration in the crown of the tubes, wherethe catched air can be accumulated. In order to eliminate the possibility of corrosion associated withhydrogen sulfide in the crown of the tubes, these will be had with PVC insuperior quadrant of 90 degrees. The vertical face of the meeting where the PVC cannot be appliedit will be protected by a epóxica coating to control corrosion problems.The main preoccupation with the steel pipe in a marine atmosphere, is the corrosion. steel pipe can be protected against the internal and external corrosion by means of onecombination of coatings, coverings and cathodic protection; nevertheless, thisit increases the cost of the material of the pipe. The coating of recommended steel pipeit consists of epóxica resin covered by cement mortar. The outside of the pipeit will protect with epóxica resin covered with a sprinkled shirt with concrete or concretereinforced drained in the site.The protection against the corrosion can be obtained or with a system of printed current orby means of sacrifice anodes (like zinc, aluminum or magnesium). During the final design,the two alternatives must be compared. The system of printed current, although is more expensive,it would have the advantage of being able to control and to monitorear the amount of required current month, that isproportional to the exposed naked metal area. Because a dielectric covering isvery effective when it is applied properly, it is assumed that most of the loss ofcurrent happens in punctures of the covering and zones of steel exposed duringPROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO91installation. On the base of technical considerations and cost, the optimal system of controlof corrosion in steel pipe it can be obtained using a system of sacrifice anodesjointly with a lining of concrete reinforced and a dielectric covering (it draws resin fromepóxica), surrounded by a sprinkled outer covering by concrete.Special StructuresThe purpose of the mailboxes in a submarine emissary is to provide access for inspection,maintenance and repair. In periodic inspection the state can be evaluated ofcoating of the tubes and the degree of corrosion.The mailboxes will settle at intervals of 300 ms approximately. The mailboxes will havediameter of 1,1 ms, sufficient size for the entrance of a diver with portable oxygen tankor one supplied from the surface, or of a vehicle to remote control (ROV by its abbreviations inEnglish) equipped with inspection instruments. The embedded ironworks will be of monel, andcovers of the mailboxes will have built-in piezometers.Structure of “Y” of the DiffuserGeometry of “Y”The diffuser system consists of two diffusing arms with multiorifices constructed onbottom of the ocean. Both diffusing arms form one “Y” with an angle of opening ofapproximately 150 degrees. This configuration allows a good dispersion duringmonths of winter, when the weak stratification of density and the coastal winds canto push the remainder water outcrop towards the coast. The union of “Y” it will have threesliding floodgates to control the flow and to facilitate the maintenance. Each floodgate isa slab of concrete that can retire. The great floodgate allows the diameter accesstotal to the main pipe, and could be used to clean the main line or for a possible oneextension of the emitter. During the normal operation of the emitter, this floodgate remainsclosed. The smallest floodgates allow that the efluente flow is directed aanyone of the diffusing arms, and allows the isolation of an arm for cleaning,inspection, or repair with a mini interruption of the flow. The increase of flow by the sidewithout blocking it will evacuate sediments. In normal operation, the sliding floodgates ofdiffuser is open and the valve groove is covered. A mailbox in the structure is providedof “Y” for inspection access.Materials of “Y”The structure of “Y” of the diffuser it would be a circular steel structure of approximately14 ms of diameter that makes in the coast, are engaged in to the site in hull and are carefullylowered to its place with a crane. Within “Y”, the flow will be lead through conduitshad with concrete, plate facts steel of 20 mm of thickness. The hatchways andaccess floodgates will be constructed of concrete reinforced.After which the structure of “Y” is placed; of the diffuser, gravel would be put withinstructure like balastro. Like an alternative to a steel like balastro, onerock battery placed appropriately could be used.Covering and Cathodic Protection of “Y”The outside of the conduits serious protected with a sprinkled covering of concrete of 50mm, with a reinforcement of mesh of welded wire. Anodes of sacrifice will settle likeadditional protection against the marine corrosion.PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO92DiffusersConsiderations of design of diffusersThe initial dilution is the main criterion of used design to establish the configuration ofdiffuser, the length of the emitter, and the depth of unloading. The system will be designed stopsto provide a minimum initial dilution with 100:1. The rates of initial dilution generallythey diminish with the increase of the unitary flows of diffuser (expressed like rate of flow bymeter of diffuser pipe). The rates of initial dilution can be maximized reducingunitary flow of diffuser until the point in which the individual spurts of the diffuser orificesno longer they are mixed.When lowering the direction of the spurt of unloading below the horizontal, can be extendedfootpath of the buoyant scroll. The longest way at the same time takes more length of drag withthe water of dilution before arriving at the retention layer. Although normally they are obtainedbetter results with angles of unloading of spurt between 0o and -ö, for orifices withgreater diameters of 65 mm, the spurts can hit in the marine bed whenangle of the unloading spurt is below the horizontal. Therefore, the diffusersthey will orient horizontally.The increases in the speed of the diffuser spurt, generally increase the rates ofinitial dilution because there is more kinetic energy available for the new drag water.Having in consideration the losses of pressure associated with speeds of spurt moredischarges, the speed of the spurt will limit approximately 3,0 m/s during the flow averageof the dry station. In order to maximize the rate of initial dilution, it is necessary to optimizediameters of diffuser orifice. An average diameter of orifice of diffuser will be used ofapproximately 100 mm, and the diameters of diffuser orifice will vary between 94 and 132 mm.If the spurts of the emitter are not mixed, forming a “fuente in línea”, there would be a section oflength of wasted diffuser that does not contribute to the initial dilution. On the other hand, ifindividual spurts are mixed in a moment, they are interfered with to each other and that way they reducerate of initial dilution. The size of the spurt grows with the length of the trajectory of the spurt,reason why, for greater depth of unloading, greater espaciamiento is required. Based onthe preliminary results, the espaciamiento of the orifices will pay attention to approximately 7 ms,measured in the same side of the diffuser. This he is the same one that 3,5 ms measured by the axis of the tube.Design of diffuser orificesIn order to obtain a distribution of as uniform flow as it is possible, will be varieddimensions of orifice, being the smallest orifices next to the structure of “Y”.As the flow leaves by the orifices of the diffuser, the flow is reduced gradually inrest of the diffuser. In order to avoid the establishment in the pipe of the diffuser, the size of the diffuserit must be reduced to maintain greater speeds of 0,6 m/s.The orifices of unloading of efluente recommended for the Emitter of North Lima areround orifices, with snaped like a bwll mouth, that are used typically in modern diffusers noburied. This type of orifice is drained integrally in the wall of the tube of concrete ofpressure during the manufacture of the same one, making its construction economic. The orificesthey form to the evenness of the outside of the tube, eliminating the possibility of being hooked by an anchordragged or fishing networks, as it can happen with the diffusers of the type of vertical tube.The total number of orifices was determined by the analyses of initial dilution. The so large meanson orifice it will depend on the depth of unloading and the objective of initial dilution. Likeit describes above, would be used an average diameter of orifice of approximately 100 mm. orifices would be amused horizontally throughout each side of the diffuser. The orificesthey would place on the line of the bottom of the pipe, to avoid the interference of the rock ofbalastro, but sufficiently below the crown of the pipe to avoid difficulties ofconstruction due to the geometry of the orifice. The orifices would be put in to 3,6 ms aeach side of the diffuser.PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO932.5.2 Alternative 2: Plant of Preliminary Treatment Avanzado17 and Submarine Emisario(preliminary design)Plant of TreatmentThe propose alternative is the following one: the waters will happen through four (4) mechanical grates andlater they will cross eight (8) desarenadores and desgrasadores as one is in the drawings ofthe plant.

According to the information that is in picture 3.3,greater domestic consumptions are registered in the area of Costanero drainage, which ispresumable, because this area of drainage concentrates the populations of the districts of stopssocioeconomic levels of Lima Metropolitan, as they are San Isidro, Miraflores and San Miguel.The lower domestic consumptions are registered in the area of drainage of the Collector Not 6, whoit concentrates the districts of Rímac. San Martín de Porres, San Juan de Lurigancho, Callao, Filesand Lurigancho, whose socioeconomic levels are between C and D.Consumptions without measurementFor the case of the not measured domestic consumptions, Plan Maestro Optimizado (PMO)2005, mention the following thing: “El consumption of the users who do not count on measurer and whoseinvoicing takes place by averages or Maxima allocation is difficult to need. Esteem thatits consumption is higher since they do not have way to control it but, on the other hand, suffercertain restriction to a greater consumption by the limitations that appear in the system ofdistribution.In the study of Yepes & Ringskog the consultants assume that the consumption per capita ofusers without micromeasurement are 30% greater than the one of the users with micromeasurement.Consulting Ing. Alexander Estrada indicates that the measured consumption cannot even get to bethe double of the measured consumption, is to say can be until the 100% greater one.In the Masterful Plan of Greeley & Hansen (1998) the consultants use unitary consumptions,as much measured as not measured, resulting of a carried out work of investigationspecially for this intention and whose result sample that the relation betweenmeasured and measured consumptions do not depend, as it is logical to suppose, on the level economic partnerof the user. The measured unitary consumption for the NSE To was not 44% greater than the consumptionmeasured Unitarian; 60% for NSE B, 83% for NSE C and 32% for NSE D.In this study (PMO) he considers himself that the percentage used in the Masterful Plan (1998)they have greater sustenance nevertheless since they are based on a real data summary,assuming that the population in general has come taking conscience in the last yearsof the necessity to save water, it is adopted preservative that the consumptions nonmeasuredthey are greater in a 40% than medidos”.In such sense, for the present study, at profile level, the same form has been considered ofestimation for the consumptions nonmeasured; that is to say, in the determination of the demand ofpotable water is considered that the measured consumptions are not greater in 40 % thatmeasured.PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO100Picture No. 3.4Levels of consumption in the zone of study (m3/mes/conexión)Source: Equipment Commercial Management3.1.5 Losses of WaterThe level of total losseses (physical and commercial losses) in year 0 is of the 38%19 ofagreement to the Masterful Plan of presented/displayed SEDAPAL 2005-2030 before the Ministry of HouseConstruction and Cleaning, a reduction of the losses is considered until 20% whichone stays throughout the years until the end of the horizon of the project. In addition, SEDAPALit counts on a Command team and Reduction of Flights that a program maintains preventiveof reduction and control of losses of potable water in the system.3.1.6 Cover of water and sewage systemIn the area of influence of the project, at the moment the water cover is 65%. This level ofcover would be increased gradually, until arriving with a cover of 95% at year 20of the horizon of the project as much for water as for sewage system.It is possible to stand out that the cover projections have been considered, consideringprojections of cover for the districts administered in Lima Metropolitan, according toMasterful plan Optimized 2005 of SEDAPAL.3.1.7 MicromediciónThe level of micromeasurement in the scope of the influence area of the project has been determinedby drainage area. For the case of the project part of this level until arriving at 95% towardsaim of the horizon of evaluation of the project.Next the information appears bases, parameters, cover, number of connectionsand consumptions to consider the total demand in the horizon of the project. Also,they present/display the results of the projection of the demand of potable water and sewage system bydrainage area.In the following pictures the information appears bases used for the calculation of demandin each area of drainage.19 According to Report of Management April 2006 - SEDAPALCM SM CM SM CM SM CM SM CM SM44,89 62.84 99.00 138.60 108.36 151.70 425.74 596.04 535.00 748,9935,10 49.14 66.65 93.31 119.16 166.83 556.36 778.90 446.11 624,5529,06 40.68 64.04 89.65 168.33 235.66 462.50 647.50 587.46 822,4530,66 42.93 80.36 112.50 246.09 344.53 474.54 664.36 432.35 605,2824,25 33.95 69.89 97.84 218.91 306.48 393.57 551.00 181.53 254,1421,65 30.30 80.06 112.09 158.64 222.09 420.66 588.93 153.97 215,5622,98 32.17 85.82 120.14 225.48 315.67 367.94 515.11 149.75 209,6523,39 32.74 98.57 138.00 242.96 340.14 367.65 514.70 137.94 193,12Cm = With measurementSM = Without measurement (adopting preservative that the measured consumptions are not greater in a 40% than the measured ones)BocanegraCommas - ChillónCOMMERCIAL DOMESTIC SERVANTCentenerioCollector Not 6CONSUMPTIONS(m3/mes/cnx)CostaneroNavyArgentinaCollector Not 19SOCIAL STATE INDUSTRIALISTPROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO101Picture No. 3.5Information bases and projection parameters, year 2005Area of Costanero Drainage(*) The population with project corresponds to the population considered for year 20Picture No. 3.äInformation bases and projection parameters on the horizon of the projectArea of Costanero DrainageLOCALITY Without Project With ProjectPRESENT POPULATION (inhabitants) (1) 181,612 178.534RATE POPULATION ANNUAL GROWTH OF (%) (2) -0,09% -0,09%DENSITY BY LOT (hab/lote) (3) 3.77 3,77PERCENTAGE OF LOSSES (4) 38,0%RESIDUAL WATER CONTRIBUTION (5) 80% 80%PRESENT POPULATION WITH CONNECTIONS WATER (public network) 121.297PRESENT POPULATION WITH CONNECTIONS WATER-DRAINAGE (public network) 121.2970District and Province of the CallaoPRESENT SUPPLY OF DESAGUES TREATMENT (capacity oftreatment of the system) (lt/sg)2005 - 2006 66,8% 66,8% 38,0% 90.8%2006 - 2007 67,00% 67,00% 20,0% 91.0%2007 - 2008 68,00% 68,00% 20,0% 92.0%2008 - 2009 69,00% 69,00% 20,0% 93.0%2009 - 2010 70,00% 70,00% 20,0% 94.0%2010 - 2011 71,00% 71,00% 20,0% 95.0%2011 - 2012 72,00% 72,00% 20,0% 96.0%2012 - 2013 73,00% 73,00% 20,0% 97.0%2013 - 2014 74,00% 74,00% 20,0% 98.0%2014 - 2015 75,00% 75,00% 20,0% 98.0%2015 - 2016 76,00% 76,00% 20,0% 98.0%2016 - 2017 77,00% 77,00% 20,0% 98.0%2017 - 2018 78,00% 78,00% 20,0% 98.0%2018 - 2019 79,00% 79,00% 20,0% 98.0%2019 - 2020 80,00% 80,00% 20,0% 98.0%2020 - 2021 81,00% 81,00% 20,0% 98.0%2021 - 2022 82,00% 82,00% 20,0% 98.0%2022 - 2023 83,00% 83,00% 20,0% 98.0%2023 - 2024 84,00% 84,00% 20,0% 98.0%2024 - 2025 85,00% 85,00% 20,0% 98.0%2025 - 2026 86,00% 86,00% 20,0% 98.0%Notes:They correspond to values projected by the UFMICROMEDIAÑOCOVER CION (%)WATER (%)COVERSEWAGE SYSTEM(%)LOSSES OFWATER (%)PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO102Picture No. 3.6Information bases and projection parameters, year 2005Area of Drainage Navy(*) The population with project corresponds to the population considered for year 20Picture No. 3.ãInformation bases and projection parameters on the horizon of the projectArea of Drainage NavyLOCALITY Without Project With ProjectPRESENT POPULATION (inhabitants) (1) 379,882 334.219RATE POPULATION ANNUAL GROWTH OF (%) (2) -0,64% -0,64%DENSITY BY LOT (hab/lote) (3) 4.00 4,00PERCENTAGE OF LOSSES (4) 38,0%RESIDUAL WATER CONTRIBUTION (5) 80% 80%PRESENT POPULATION WITH CONNECTIONS WATER (public network) 246.554PRESENT POPULATION WITH CONNECTIONS WATER-DRAINAGE (public network) 246.5540District and Province of the CallaoPRESENT SUPPLY OF DESAGUES TREATMENT (capacity oftreatment of the system) (lt/sg)2005 - 2006 64,9% 64,9% 38,0% 87.3%2006 - 2007 67,00% 67,00% 20,0% 89.0%2007 - 2008 68,00% 68,00% 20,0% 90.0%2008 - 2009 69,00% 69,00% 20,0% 91.0%2009 - 2010 70,00% 70,00% 20,0% 92.0%2010 - 2011 71,00% 71,00% 20,0% 93.0%2011 - 2012 72,00% 72,00% 20,0% 94.0%2012 - 2013 73,00% 73,00% 20,0% 95.0%2013 - 2014 74,00% 74,00% 20,0% 96.0%2014 - 2015 75,00% 75,00% 20,0% 97.0%2015 - 2016 76,00% 76,00% 20,0% 98.0%2016 - 2017 77,00% 77,00% 20,0% 98.0%2017 - 2018 78,00% 78,00% 20,0% 98.0%2018 - 2019 79,00% 79,00% 20,0% 98.0%2019 - 2020 80,00% 80,00% 20,0% 98.0%2020 - 2021 81,00% 81,00% 20,0% 98.0%2021 - 2022 82,00% 82,00% 20,0% 98.0%2022 - 2023 83,00% 83,00% 20,0% 98.0%2023 - 2024 84,00% 84,00% 20,0% 98.0%2024 - 2025 85,00% 85,00% 20,0% 98.0%2025 - 2026 86,00% 86,00% 20,0% 98.0%Notes:They correspond to values projected by the UFYEAR COVERWATER (%)COVERSEWAGE SYSTEM(%)LOSSES OFWATER (%)MICROMEDICION(%)PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO103
