Overview
Parres wastewater treatment plant serves 2,702 people in Parres El Guarda, Ciudad de México, Mexico. It provides secondary treatment and discharges 255.74 cubic meters per day.
Parres is a wastewater treatment plant located in the Tlalpan borough of Parres El Guarda, within Ciudad de México, Mexico. It serves a population of approximately 2,702 people, making it a small-scale municipal facility. The plant is situated in the southern part of the Mexico City metropolitan area, an inland region with significant urban and ecological pressures. The plant operates with secondary treatment, which is the standard biological treatment required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater before discharge. With a designed capacity of 648.00 cubic meters per day and an actual discharge volume of 255.74 cubic meters per day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local watercourses that eventually drain into the Balsas River basin, one of Mexico's major river systems. This basin supports diverse aquatic life and provides water for agriculture and communities downstream. The plant's secondary treatment helps reduce organic pollutants and suspended solids, protecting the ecological health of the receiving waters.
Environmental context
The plant's discharge flows into the Balsas River basin, which drains into the Pacific Ocean via the Balsas River. This watershed is ecologically significant, supporting a variety of fish and bird species. The region experiences a subtropical climate with seasonal rainfall, making consistent wastewater treatment crucial to prevent pollution during dry periods when dilution is limited.
