Manantial Wastewater Treatment Plant, Tepojaco, Hidalgo, Mexico

Manantial is a wastewater treatment plant located in Tepojaco, within the municipality of Tizayuca, Hidalgo, Mexico. It serves a population of approximately 7,302 people, classifying it as a small to medium agglomeration under Mexican wastewater regulations. The plant is situated inland, away from coastal areas, and operates as part of the region's municipal sanitation infrastructure. The plant provides secondary treatment, which is the standard level required by Mexican environmental law (NOM-001-SEMARNAT-1996) for discharges into inland water bodies. With a designed capacity of 691.20 cubic meters per day and a matching discharge volume, the plant operates at full capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with national discharge standards. The treated effluent is discharged into local watercourses that eventually drain into the Gulf of Mexico via the Pánuco River basin. The surrounding region is semi-arid, making water quality management critical for downstream ecosystems and agricultural users. The plant's operation helps protect local streams and the larger hydrological network from untreated sewage pollution.

The plant discharges into the Pánuco River basin, which flows through central Mexico and empties into the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for irrigation and human consumption. The semi-arid climate of Hidalgo makes the receiving water bodies particularly sensitive to pollution, as low flow conditions can concentrate contaminants. Proper treatment at Manantial helps maintain ecological balance in downstream rivers and estuaries.
