As the near marine coast were mentioned previously, in general, andthe Bay of the Callao, in individual, strongly is contaminated, and consequentlythe health of the settlers is affected who attend beaches. Also it is affecteddrastically the marine ecosystem and later the consumption of marine speciescontaminated it affects the population of smaller economic resources. Therefore,health of the population is in danger situation and the contaminated atmosphere.• With ProjectWith the Project the residual waters will be dealt that at the moment are spilleddirectly to the sea and the Rímac river. Planta de Tratamiento de Residual AguasTaboada will almost deal with all the volumes residual waters until year 2018 andthe Submarine Emissary will serve the of great volume tips until year 2030.• Benefits of the Project: With the treatment of residual waters, the benefitsof the project they include among others the following ones:􀀹 Elimination of the microbiological, chemical and aesthetic contamination ofbeaches of Lima and Callao, recovering them to be used like places ofrecreation for the population.􀀹 Reduction of the diseases related to the contact to residual watersor the originated ones by consumption of contaminated hidrobiológicos resources.􀀹 The atmosphere adapted for the accomplishment of future tourist projects.􀀹 Recovery of the marine ecosystem of the effects of the dispositioninadequate of residual waters.􀀹 To avoid conflicts of use of the marine coastal zones like the one of dispositionof waters served and zones as recreation simultaneously.The economic benefits of the project are generally the costs avoided forsociety and economy of the country. It has not been possible to quantify the benefitseconomic, but the following elements can give light to the costs that canto be avoided by the project:• In ten weeks of year 1991, the epidemic of the rage in Peru, it cost to the nationthan billion dollars in losses, by orders annulled more ofexports and cancellations of tourism trips.• Aside from the damages to the health of the town, the economic loss to the nation inthese ten weeks, it was more than three times of which the government of Peru hadinvested in the water sector in the ten previous years.PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO1443,6 Social EvaluationIn order to carry out the social evaluation of the component residual waters they will be groupedthe costs of investment, as well as the costs of operation and maintenance beingthese turned of prices deprived to social prices for all the period ofevaluation.For the case of the residual water component, it is not possible to quantifybenefits in monetary form for their evaluation, therefore, are only consideredinvestment costs and the costs of operation and maintenance, turning the pricesprevailed to social prices for all the period of evaluation.The social evaluation requires to define correction factors to fit the pricesprevailed to social prices. On the matter there are two great groups of these factors:Direct taxes (imposed to the rent), that will not be considered like costsadditional of the project, since although it is an exit of money for the institution,it is also a benefit for the State, then his effect is annulled.Distortions in the valuation of market of the goods and services, that cause that it isdifferent from the social valuation. Between these distortions are the taxesindirect (IGV, ISC and tariffs)Then: Social cost = (Factor of Corrección)*(Costo of Market)The factors of conversion or corrección24 vary according to the nature of the goods andservices that will be used in the project, for example are had:- Factor of correction of nontransables goods of national origin or: it must includeeffects in the collection of taxes; it is considered like the inverse one of one plus the IGV.FC = 1/(1+0.19)- Factor of correction of goods of concerned origin or transables: it must include the pricesocial of the currency, calculated by the MEF in 1.08 and also the effects of the IGV andtariffs, that stop the case of the materials and equipment of the projects ofcleaning is of 5.5%; the correction factor is considered like:FC = 1.08/(1+0.055)(1+0.19)- Factor of correction of the turned manual labor: it must include the tax onpersonal income (10% against the account of tax to the rent): FC = 1/(1+0.10)- Factor of correction of described and combustible manual labor is not applieddirectly. Finally, the resulting factors of correction of I calculate previousthey are the following ones:Picture 3.43Factors of Correction of Prices Deprived to Social PricesComponent FactorIt descries/Goods and services Transables or Importados (*) 0.8602Goods and services nonTransables or Nacionales 0.8403Manual labor nonDescribed 0.8600Described manual labor 0.9091Fuels 0.6600Own elaborationthe 24 factors of conversion have been determined by the Ministry of Economy and Finances inDirective no. 004-2002-EF/68.01 General directive of the National System of Public Investment, approved withAnnexed RD No. 012-2002-EF/6801- 9: Parameters of Evaluation.PROFILE: CONSTRUCTION OF THE PLANT OF RESIDUAL WATER TREATMENTTABOADA And SUBMARINE EMISSARY - DISTRICT And PROVINCE Of the CALLAO145The methodology of application of the factors of correction of deprived prices asocial prices can o'clock see it 3.4.1 Costs of Investment.The flow of total social costs is determined fitting the flow of costs to prices ofmarket, so that they reflect his social values.In function to these flows, the present value of total the social costs is considered ofeach alternative, considering that the social value of the money in the time is 14% (costof social opportunity of the capital)
