Diagnóstico del estado inicial y desarrollo de la metodología para la puesta en marcha de la planta de tratamiento de aguas residuales en la comunidad de San Pedro, cantón Azogues, Provincia del Cañar

Abstract

CONDITION FOR PUBLICATION OF PROJECT. Access to efficient wastewater treatment is essential for both public health and environmental protection. In the community of San Pedro, the wastewater treatment plant (WWTP), built in 2022, remains inoperative, leading to the direct discharge of wastewater into the Dudas River, which negatively impacts water quality and the local ecosystem. This project aims to assess the current condition of the WWTP and identify the factors preventing its operation, proposing an appropriate methodology for its commissioning, as well as a plan for its operation and maintenance. Conducting this assessment represents a crucial first step toward aligning with Sustainable Development Goal (SDG) 6, which aims to ensure access to safe drinking water, sanitation, and hygiene for all. To develop this study, various field inspections were conducted, community clean-up initiatives were organized, and laboratory tests (granulometric analysis), water quality assessments, and topographic surveys were carried out. These activities provided insight into the current state of the treatment unit. The results revealed both design and construction deficiencies, sludge accumulation, unit blockages, leaks and seepage in the upflow filter, inadequate filter material, and a complete lack of maintenance. Upon conclusion of this study, it was determined that the WWTP requires intervention to address the identified issues before its commissioning, along with the implementation of an operation and maintenance plan to ensure proper functionality and prevent future shutdowns.
