Desarrollo de una propuesta de mejoras al sistema de abastecimiento de agua para la comuna Chilibulo Marcopamba la Raya.

Abstract

The purpose of this titling project is to establish the water quality of the Chupazuro 1 and 2, Luriyaku and Ashinituro springs of the Chilibulo-Marcopamba - La Raya Commune, which is in the southwestern area of Quito in the urban parishes of Chilibulo and La Mena. To determine the quality of water resources in the commune, two sampling points were selected: Catchment (P1) and storage tank (P2), where on-site characteristics were measured, and samples were collected for laboratory analysis. The parameters measured in the field were: temperature, pH, conductivity, dissolved oxygen, and turbidity, while laboratory analyses were carried out for: fecal and total coliforms, COD, BOD5, phosphates, iron, manganese, nitrites, nitrates, ammonium, sulfates, and solids content. The results were compared with the Unified Text of Secondary Environmental Legislation (TULSMA), which determined that the parameters analyzed met the criteria of the regulation. In addition, the Water Quality Index was determined, which verified the status of the water resource in the sites selected for sampling, with the result that the water is in acceptable condition throughout its journey from the catchment to the storage tank, but for the raw water to be potable it needs at least one disinfection process. The proposals to improve the quality of the Comuna's water resources are the implementation of a drip hypochlorinator with float, which is a technology that allows supplying small doses of chlorinated solution to the flow entering the storage tank; the maintenance and operation of the supply system; and the installation of a sedimentation tank. Based on the results, a technical report was made and will be delivered to the community so that they can analyze and implement the project.
