Análisis comparativo de los criterios de diseño de redes de alcantarillado entre normas latinoamericanas y su contraste con la ecuatoriana

Abstract

Population growth brings with it numerous problems, including the need to evacuate wastewater, which is why it is increasingly important to have lower-cost sanitary sewer designs, which satisfy hydraulic restrictions, and obtain more efficient and safe projects. and economical. Despite the fact that over time the concept and practice of sanitary engineering has improved in favor of an adequate drainage and evacuation of wastewater, there are still places in Latin American countries that lack sanitation facilities, due to the scarcity resources and the high cost of conventional solutions. The objective of this qualification work is to develop a comparative analysis of the technical criteria for the design of sewage collection networks currently in force among the Latin American standards such as: Norma Argentina AySA, Norma Boliviana, Norma Brasileña NBT, Norma Chilena, Norma Colombiana RAS, Mexican Norm MAPAS, Peruvian Norm, in contrast to the Ecuadorian Norm CPE INEN 5 to study the feasibility of applying them in Ecuador, given that the national design norms have not been updated since 1992. According to the context of the problem, it is intended to optimize the design parameters and hydraulic restrictions of wastewater collection networks such as: minimum diameter, slopes, speeds, hydraulic flow depth, among others, which prevent reducing construction costs and maintenance. In addition, bibliographic research is used to know the sanitary sewer alternatives currently applied.
