SUchil Wastewater Treatment Plant, Técpan de Galeana, Guerrero, Mexico

SUchil is a wastewater treatment plant located in Técpan de Galeana, Guerrero, Mexico, serving a population of approximately 4,564 residents. The plant operates with secondary treatment, a standard level for municipal facilities in Mexico, and processes an average daily flow of 432 cubic meters against a designed capacity of 864 cubic meters. As a secondary treatment facility, SUchil provides biological treatment to reduce organic matter and suspended solids. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. Plants of this scale are typically required to meet secondary treatment standards to protect receiving waters. The plant is situated within 10 kilometers of the Pacific Ocean, making its discharge environmentally significant. Treated effluent likely reaches the ocean via local streams or direct outfall, impacting coastal water quality and marine ecosystems. The region's tropical climate and proximity to tourist areas underscore the importance of effective wastewater management to prevent nutrient pollution and protect coastal habitats.

The plant discharges treated wastewater into the Pacific Ocean near Técpan de Galeana, part of the Guerrero coastal watershed. This area supports diverse marine life, including fish and crustaceans, and is important for local fisheries and tourism. Effective secondary treatment helps reduce nutrient loads that could otherwise contribute to algal blooms and degrade nearshore water quality.
