Estacion Rincon Wastewater Treatment Plant, Rincón de Romos, Aguascalientes, Mexico

Estacion Rincon is a municipal wastewater treatment facility located in Rincón de Romos, Aguascalientes, Mexico. The plant serves a small population of 913 residents, providing secondary treatment to manage local wastewater. It is situated in the semi-arid highlands of central Mexico, an area where water resources are critical for both agriculture and domestic use. The plant operates with a designed capacity of 86.40 cubic meters per day and discharges a similar volume, indicating full utilization. Under Mexican regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is the standard for municipal wastewater to meet discharge quality criteria. For small communities like this, the plant plays a key role in preventing untreated sewage from entering local waterways. The treated effluent is likely discharged into an intermittent stream or arroyo that drains into the Aguascalientes basin, eventually contributing to the Rio Verde or Rio Santiago system. This watershed is part of the larger Lerma-Santiago-Pacific hydrological region, which supports agriculture and provides water for downstream communities. Proper treatment helps protect local groundwater and surface water from contamination, preserving the ecological health of the region.

The plant discharges into the Aguascalientes basin, part of the Lerma-Santiago-Pacific hydrological region. The treated effluent likely flows into intermittent streams that feed the Rio Verde, which eventually reaches the Rio Santiago and the Pacific Ocean. This watershed supports irrigated agriculture and provides habitat for native fish and aquatic species. The semi-arid climate makes water quality management essential to prevent eutrophication and protect downstream water users.
