3.6.1 Analysis Costo/Efectividad de Residual AguasWith the purpose of evaluating the residual water component one has been useddenominated methodology Costo/Efectividad analysis, because it is not possibleto monetarily quantify the benefits attributable to this service.Therefore, this one methodology of evaluation allows us to express the benefits ofresidual waters in nonmonetary units (served population beneficiary) thatthey allow to measure the cost average by served inhabitant in order to obtain the objectives ofproject.For the economic evaluation by means of the method of Costo/Efectividad it is hadconsidered the total of costs of investment and operation and maintenance of watersresidual to social prices.The results of the social evaluation of the Costo/Efectividad throw the following oneresult in the raised alternatives:Picture No. 3.44To see picture no. 3.47Picture No. 3.45To see picture no. 3.48Picture No. 3.46To see picture no. 3.49Residual WatersCost ofInvestmentSocialCost ofOr & MSocialCostTotalSocialHOISTSOCIAL(S/./hab)Alternative No. 1 (Social) 308.689.448 999.340.693 1.308.030.141 82SOCIAL EVALUATION PLANT OF RESIDUAL WATER TREATMENT TABOADAResidual WatersCost ofInvestmentSocialCost ofOr & MSocialCostTotalSocialHOISTSOCIAL(S/./hab)Alternative No. 2 (Social) 196.979.454 330.590.090 527.569.544 39SOCIAL EVALUATION PLANT OF RESIDUAL WATER TREATMENT TABOADAResidual WatersCost ofInvestmentSocialCost ofOr & MSocialCostTotalSocialHOISTSOCIAL(S/./hab)Alternative no. 1 and 2 (Social) 748.739.758 2.769.053 751.508.811 93SOCIAL EVALUATION SUBMARINE EMISSARYPROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO146Picture No. 3.47Own ElaborationRECOMMENDATION OF THE FINAL EQUIPMENT OF DISPOCION OF SEDAPAL IN THE CASESIN WHICH THE OPTIMAL PERIOD OF DESIGN OF THE PLANT CONCLUDES BEFOREPERIOD OF EVALUATION Or HORIZON OF EVALUATION.It is necessary to explain that due to the magnitude of Planta de Tratamiento Taboada andSubmarine emissary and in diverse meetings of coordination with the personnel ofManagement of Production that works directly in the processes of treatment ofdiverse Plants located in Lima I determine that turned the period of optimal ofdesign of same the its cost of operation and maintenance is increased of 3% a5%, for the following reasons:1. The specialized workers (working) are personnel who becomes qualifiedconstantly and also he has benefits. On the other hand as it is Planta withconsiderable volume goes away to continue contracting personal and it goes away to continue applying newtechnologies which means variation in the costs.2. When finalizing the period of optimal design, the materials and insumos they cannotto stay the price constant always is increasing.3. The Equipment that is used in Planta has one limited life utility and hasto replace them inclusively when they fail before. The technological change does that noalways is the original equipment to be discontinued and isnecessary to replace them by other better and naturally most expensive ones.2005 - 2006 0 0 0 02006 - 2007 4.923.867 0 4.923.867 02007 - 2008 6.154.834 0 6.154.834 02008 - 2009 112.590.461 0 112.590.461 02009 - 2010 185.020.287 38.161.522 223.181.808 4,606,9462010 - 2011 0 55.952.346 55.952.346 4,679,2472011 - 2012 0 57.425.631 57.425.631 4,753,2702012 - 2013 0 58.936.022 58.936.022 4,829,0552013 - 2014 0 60.488.089 60.488.089 4,906,6432014 - 2015 0 62.079.769 62.079.769 4,986,0722015 - 2016 0 51.481.306 51.481.306 5,067,3862016 - 2017 0 53.157.133 53.157.133 5,150,6302017 - 2018 0 54.878.148 54.878.148 5,235,8442018 - 2019 0 56.645.354 56.645.354 5,323,0782019 - 2020 0 58.459.613 58.459.613 5,412,3742020 - 2021 0 60.322.460 60.322.460 5,503,7822021 - 2022 0 62.235.010 62.235.010 5,597,3492022 - 2023 0 64.198.472 64.198.472 5,693,1262023 - 2024 0 66.215.597 66.215.597 5,791,1622024 - 2025 0 68.287.764 68.287.764 5,891,5102025 - 2026 0 70.416.458 70.416.458 5,994,224308,689,448 999.340.693 1,308,030,141* VAC = 433,836,170* PROM Benef. population = (pob year 4 +pob year 20)/2 5.300.585 hab.* HOISTS 82 = VAC = benefitted S./pobladorpro, pob.
