Cochoapa Wastewater Treatment Plant, Ometepec, Guerrero, Mexico

Cochoapa is a municipal wastewater treatment plant located in Ometepec, Guerrero, Mexico. It serves a population of approximately 9,127 people, classifying it as a small to medium agglomeration. The plant is situated inland, away from coastal areas, and operates under Mexico's national water regulations. The plant provides secondary treatment, which is the standard level required for urban wastewater in Mexico under NOM-001-SEMARNAT-1996. With a designed capacity of 1,209.6 m³/day and a current discharge volume of 864 m³/day, it operates at about 71% capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that eventually drain into the Pacific Ocean via the region's river systems. The plant plays a key role in protecting downstream water quality and public health in the Ometepec area, supporting the ecological health of the surrounding watershed.

The plant discharges into local streams that are part of the Costa Chica region of Guerrero, ultimately flowing into the Pacific Ocean. This coastal watershed supports diverse aquatic life and is important for local fisheries and agriculture. Proper treatment helps prevent nutrient pollution and protects downstream ecosystems.
