Diseño del sistema de alcantarillado sanitario para la comunidad “El Prado”, perteneciente al cantón Daule provincia del Guayas.

Abstract

This research work was carried out in the community "El Prado" belonging to the Cantón Daule Province of Guayas, through a mixed qualitative-quantitative approach, with the aim of designing, modeling the sanitary sewer system and proposing the treatment of the wastewater suitable for the community. With a design period of 25 years and a future population of 535 inhabitants, from the calculations provided by the Excel spreadsheet, a design flow of 9.70 l / s was obtained; in turn, the design of the primary network consists of 160- and 200-mm diameter pipes the secondary and tertiary network of 160 mm in diameter. The collectors of the adopted sanitary sewer system meet the criteria of the Ecuadorian standard CPE INEN 5 with slopes, speeds, hydraulic ratios Q/Qo and shear stresses. The proposed WWTP for the Prado community is composed of: a pretreatment that consists of an inlet channel and a screening system made up of 9 grids, a primary treatment that consists of two septic tanks with dimensions of 12 m2 of surface and a depth of 1.70 m and, finally, a secondary treatment consisting of two constructed wetlands. This proposed WWTP was designed to comply with the TULSMA standard, ANNEX1 BOOK VI and in this way obtain a correct removal of D.Q.O5, D.B.O, Total Phosphorus, Total Suspended Solids, Nitrogen and Fecal Coliforms; the total project budget is $ 169,708.45
