Ciudad de Los NiNos Wastewater Treatment Plant, Aguascalientes, Mexico

Ciudad de Los NiNos is a wastewater treatment plant located in Aguascalientes, Mexico, within the municipality of Aguascalientes. The plant serves a small population of 91 people and operates at a secondary treatment level, which is typical for small-scale facilities in the region. The plant has a designed capacity of 172.80 m³/day and currently discharges 8.64 m³/day of treated wastewater. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids. Mexican regulations for wastewater treatment, such as NOM-001-SEMARNAT, set discharge standards for pollutants, and plants of this scale are expected to comply with these norms. The treated effluent from the plant is discharged into the local environment, contributing to the water quality of the surrounding watershed. Aguascalientes is located in the semi-arid region of central Mexico, where water resources are limited and treatment plants play a crucial role in protecting local water bodies and supporting sustainable water use.

The plant discharges into the local watershed within the Aguascalientes region, which is part of the Lerma-Santiago-Pacific hydrological basin. This basin drains into the Pacific Ocean via the Santiago River. The area is semi-arid, making water quality management critical for downstream ecosystems and agricultural use. The treated effluent helps maintain the ecological balance of local streams and supports the region's water cycle.
