Tapias Viejas Wastewater Treatment Plant, Aguascalientes, Mexico

Tapias Viejas is a secondary-level wastewater treatment plant located in the community of Tapias Viejas, within the municipality of Jesús María, Aguascalientes, Mexico. Serving a population of approximately 986 residents, this facility is part of the local municipal wastewater infrastructure managed under Mexican environmental regulations. The plant employs secondary treatment processes, which typically involve biological degradation of organic matter, meeting the standard requirements for inland communities of this scale. With a designed capacity of 172.80 cubic meters per day and an average daily discharge of 93.31 cubic meters, the facility operates below its full capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain into the Rio Grande de Santiago basin, which flows westward through Jalisco and into the Pacific Ocean. This watershed supports agricultural activities and provides habitat for diverse aquatic species, making proper treatment essential for maintaining downstream water quality and ecosystem health.

The plant discharges into the Rio Grande de Santiago basin, which flows through central Mexico and eventually reaches the Pacific Ocean. This watershed supports agricultural irrigation and sustains aquatic ecosystems, including fish and migratory bird populations. Effective secondary treatment helps protect these downstream environments from nutrient pollution and organic loading.
