Diseño de una PTAR para la Mancomuna Monteverde-Jambelí de la Parroquia Colonche, provincia Santa Elena

Abstract

The project involves designing a Wastewater Treatment Plant (WWTP) for the Monteverde–Jambelí association to replace a deficient oxidation pond system. The objective is to propose a technically and economically viable alternative using nature-based solutions that comply with TULSMA VI regulations. This is justified by the need to prevent water pollution and protect regional public health. The methodology employed for the design was scientific research, accompanied by a technical visit and collection of samples for the characterization of wastewater through laboratory analysis. The design included the use of manual screens, a horizontal flow sand trap with a Parshall flume, an existing oxidation pond, and horizontal subsurface flow wetlands. The system was designed using CONAGUA international standards, and materials such as 0.75 mm HDPE membrane and filter gravel were specified for the rehabilitation of the existing pond and artificial wetland. For rural communities, decentralized systems are an ideal option due to their low complexity and low operating and construction costs, as well as their adaptability to local conditions. Finally, community participation is essential for the success and proper functioning of the proposed system.
