Corral Falso Wastewater Treatment Plant, Veracruz, Mexico

Corral Falso is a wastewater treatment plant located in the municipality of Emiliano Zapata, Veracruz, Mexico. Serving a population of 913, it is a small-scale facility that provides secondary treatment for municipal wastewater. The plant is situated inland, away from coastal areas, and its operations are part of the local sanitation infrastructure. The plant has a designed capacity of 86.40 cubic meters per day and discharges a similar volume of treated wastewater. As a secondary treatment facility, it meets the standard requirements for organic matter and solids removal. In Mexico, wastewater treatment plants are regulated under the National Water Law and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants into national waters. The treated effluent from Corral Falso likely flows into a local watercourse that drains into the Gulf of Mexico via the Jamapa River or other nearby rivers. The region's aquatic ecosystems benefit from the reduction of pollutants, supporting biodiversity in the lower basin and coastal areas.

The plant's discharge enters a local stream that is part of the Jamapa River basin, which flows into the Gulf of Mexico near the port of Veracruz. This watershed supports diverse aquatic life and is important for local fisheries. The secondary treatment helps protect downstream water quality and reduces nutrient loading that could otherwise contribute to eutrophication in coastal waters.
