Overview
Paredes wastewater treatment plant in Aguascalientes, Mexico, serves 1,506 people with secondary treatment. It discharges 142.56 thousand m³/year and has a designed capacity of 86.40 thousand m³/year.
Paredes is a municipal wastewater treatment plant located in the town of Paredes, within the municipality of San José de Gracia, Aguascalientes, Mexico. The facility serves a population of approximately 1,506 residents, reflecting its role in managing domestic wastewater for a small community in the central highlands of Mexico. The plant provides secondary treatment, which is the standard biological treatment process for removing organic matter and suspended solids. With a designed capacity of 86.40 thousand m³ per year and an actual discharge volume of 142.56 thousand m³ per year, the plant operates at a utilization rate exceeding its nominal capacity, indicating potential overloading. Mexican wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which set discharge limits for pollutants. The treated effluent is discharged into local watercourses that drain into the Rio Grande de Santiago basin, eventually reaching the Pacific Ocean. The plant's operation is critical for protecting local water quality in the semi-arid region of Aguascalientes, where water resources are scarce and sensitive to pollution.
Environmental context
The plant discharges into the Rio Grande de Santiago basin, which flows through the states of Aguascalientes, Jalisco, and Nayarit before emptying into the Pacific Ocean. This watershed supports agricultural irrigation and provides habitat for aquatic species. The semi-arid climate makes water quality management particularly important for downstream communities and ecosystems.
