Overview
Villa de Cos wastewater treatment plant serves the town of Villa de Cos in Zacatecas, Mexico. It is an inland facility treating wastewater for a population of approximately 6,883.
The Villa de Cos wastewater treatment plant is located in the town of Villa de Cos, in the state of Zacatecas, Mexico. The facility serves a population of around 6,883 residents, making it a small-scale municipal treatment plant in an arid inland region. As a Mexican wastewater treatment plant, it operates under the national regulatory framework established by the Ley de Aguas Nacionales and Normas Oficiales Mexicanas (NOMs), which set discharge standards for municipal wastewater. For small agglomerations like Villa de Cos, secondary treatment is typically required to reduce organic matter and suspended solids before discharge. The plant discharges treated effluent into local watercourses that eventually drain into the endorheic basins of northern Mexico. The region's semi-arid climate means that water resources are scarce, and the plant plays a crucial role in protecting local groundwater and surface water quality, supporting agricultural reuse and ecosystem health.
Environmental context
The plant is located in the semi-arid Zacatecas region, where water is a limited resource. Treated effluent likely discharges into intermittent streams or arroyos that feed into the endorheic basins of the Mexican Plateau, such as the Bolson de Mapimi. These basins have no outlet to the sea, making water quality management critical for local ecosystems and agricultural reuse. The plant helps prevent contamination of shallow aquifers and supports the region's water sustainability.
