Evaluación de la planta de tratamiento de aguas residuales de la comunidad Gamboa perteneciente al cantón Pelileo, provincia de Tungurahua

Abstract

The location of the wastewater purification system in the tourist area of Gamboa, in the Pelileo canton of Tungurahua province, has raised concerns about public health safeguards and environmental preservation. Thus, an examination was conducted to verify whether the cleaning procedures were functioning properly and fulfilling their purpose of purifying the wastewater. To carry out this examination, a topographic study was conducted to facilitate the measurement of the functional units of the treatment plant and the development of a general building design with "as-built" plans. Data on inflow and outflow rates were also collected using the volumetric method to determine the maximum flow and perform laboratory analysis based on a composite sample to evaluate the physicochemical parameters of the untreated wastewater (influent) and the treated wastewater (effluent), comparing the obtained values with those established by the TULSMA 2015 regulations. The analysis confirmed that the operational effectiveness of the wastewater treatment system was within acceptable limits. However, an opportunity to improve the efficiency of sludge treatment was identified, leading to the need to install a cover to facilitate proper dehydration of the solid waste produced in the septic tank. Additionally, an operation and maintenance manual was developed to ensure the longterm optimal performance of the plant and secure the service life of the hydraulic infrastructure.
