Reforma Agraria Wastewater Treatment Plant, Marqués de Comillas, Chiapas

Reforma Agraria is a wastewater treatment plant located in Marqués de Comillas, Chiapas, Mexico. It serves a small population of 18 people, reflecting its role in a rural community. The plant is situated inland, approximately 16.275° N, -90.869° W, in the southern region of Mexico near the border with Guatemala. The plant provides secondary treatment, which is a standard biological process that removes organic matter and suspended solids. It has a designed capacity of 518.40 cubic meters per day and currently discharges 259.20 cubic meters per day. As a small facility in Mexico, it operates under the national water quality regulations enforced by CONAGUA (Comisión Nacional del Agua), which sets discharge standards for municipal wastewater. The treated effluent from Reforma Agraria likely drains into local watercourses that feed into the Usumacinta River basin, one of the largest river systems in Mexico and Central America. This basin supports diverse aquatic ecosystems and ultimately flows into the Gulf of Mexico. The plant's secondary treatment helps protect downstream water quality in this ecologically significant region.

The plant's discharge enters local streams that are part of the Usumacinta River basin, which flows through the Lacandon Jungle, a region of high biodiversity. The Usumacinta River eventually reaches the Gulf of Mexico, supporting mangrove forests and coastal fisheries. Secondary treatment reduces organic pollution, helping to maintain water quality in this sensitive tropical watershed.
