The Ocotlán de Morelos wastewater treatment plant is a municipal facility serving the town of Ocotlán de Morelos in the state of Oaxaca, Mexico. With a population served of around 13,400, it is classified as a small to medium agglomeration under Mexican water management frameworks. The plant is situated in the Valles Centrales region, an area characterized by a semi-arid climate and significant agricultural activity. Mexican wastewater treatment plants of this scale typically employ secondary treatment technologies such as activated sludge or stabilization ponds, in line with national standards (NOM-001-SEMARNAT-1996). Its operational status and compliance with discharge limits are overseen by the National Water Commission (CONAGUA) and state authorities. The treated effluent from the plant is discharged into local water bodies that drain into the Atoyac River basin, which flows through the Central Valleys of Oaxaca. This river system is ecologically important, supporting diverse aquatic life and providing water for irrigation and domestic use downstream. The plant plays a key role in protecting water quality in this region, reducing pollution loads before they reach sensitive ecosystems.
Environmental context
The plant discharges into the Atoyac River basin, which flows through the Valles Centrales of Oaxaca and eventually drains into the Pacific Ocean via the Tehuantepec River. This watershed supports a variety of aquatic species and is critical for local agriculture and drinking water supplies. The region's semi-arid climate makes water quality management particularly important for maintaining ecological balance and human health.
