Jarillas Wastewater Treatment Plant, Aguascalientes, Mexico

Jarillas wastewater treatment plant is located in the town of Jarillas, within the municipality of Asientos, Aguascalientes, Mexico. The facility serves a population of approximately 1,643 residents, providing secondary treatment for municipal wastewater. It is situated in an inland region, over 10 kilometers from the coast but within 50 kilometers. The plant operates with a designed capacity of 86.40 cubic meters per day and currently discharges 155.52 cubic meters of treated wastewater daily, indicating it is handling a volume above its nominal capacity. As a secondary treatment facility, it meets the standard requirements for municipal wastewater treatment in Mexico, which are governed by the Federal Law for Water and the official Mexican standards (NOM-001-SEMARNAT) for effluent quality. The treated effluent from Jarillas is discharged into local water bodies that eventually drain into the Gulf of Mexico via the Panuco River basin. The plant plays a crucial role in protecting the local environment by reducing organic pollutants and pathogens before discharge, supporting the health of downstream aquatic ecosystems and communities.

The plant's discharge enters local streams that are part of the Panuco River basin, which flows eastward to the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for agricultural and domestic use in the region. Effective treatment at Jarillas helps prevent nutrient enrichment and contamination in downstream water bodies, preserving water quality for both ecological and human needs.
