Diseño de un sistema de alcantarillado combinado y estructuras especiales de descarga para el proyecto de urbanización “Balcones del Chamizal”, ubicado en el barrio Princesa Toa, parroquia Conocoto, cantón Quito, provincia Pichincha

Abstract

The “Balcones de Chamizal” urban development will be located in the El Chamizal sector of the parish of Conocoto, southwest of Quito. This area has all the basic services and a temperate climate. The project includes 17 blocks of buildings with 2 apartments per floor, a 2-story community house, and a guardhouse. The buildings will have between 5 and 8 stories, except for blocks 6 and 17, which will have 2 apartments per floor for the most part. The sewer system will be combined and will have to pass through a pipeline to discharge into the creek and connect to the public sewer system. The special design of the sewer system will overcome the challenge of the pipeline crossing, benefiting the 240 families in the project. A combined sewer network will be planned with special structures, complying with regulations for efficient hydraulic operation. A hydraulic analysis will be carried out taking into account hydrological conditions, land use and expected water flows. The design will be carried out using an Excel spreadsheet to determine depths, lengths, diameters and structures required to dissipate energy. In addition, complementary works such as flow separator, jump well, trapezoidal section with hydraulic tunnel option will be included to solve existing problems. Special structures such as the Type II Jump Well is the most suitable option for discharge into the P13 well, ensuring effective energy dissipation. This type of structure also controls the slopes and flow velocities within the pipelines in accordance with EMAAP-Q (2009). In addition, the efficiency of the design of the thin-walled submerged orifice for the flow separator is highlighted, as well as the practical approach used in the design of the sewer network using Excel, as described in Annex 4.
