Rancho Santa Monica Providencia Wastewater Treatment Plant, Aguascalientes, Mexico

Rancho Santa Monica Providencia is a wastewater treatment plant located in Aguascalientes, Mexico, serving a population of 5,476. The plant operates under Mexico's national water regulations, which set standards for wastewater treatment and discharge to protect water resources. The plant provides secondary treatment, a standard level for communities of this size in Mexico. With a designed capacity of 1,728.00 cubic meters per day and a current discharge volume of 518.40 cubic meters per day, the facility operates well below its capacity, indicating room for future growth. The treated effluent is discharged into the local watershed, which ultimately drains into the Rio San Pedro, a tributary of the Rio Grande de Santiago. This river system flows into the Pacific Ocean, supporting diverse aquatic life and providing water for agricultural and urban uses downstream.

The plant discharges into the Rio San Pedro basin, part of the larger Rio Grande de Santiago system that drains into the Pacific Ocean. This watershed supports agricultural irrigation and provides habitat for native fish species. The region's semi-arid climate makes water quality management critical for maintaining ecosystem health and downstream water availability.
