San Pedro Tlamimilulpan is a municipal wastewater treatment plant located in the town of Tlalmimilulpan (San Pedro), within the municipality of Tetela del Volcán, Morelos, Mexico. The plant serves a population of approximately 1,643 residents, reflecting a small agglomeration typical of rural communities in central Mexico. The facility provides secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT) for municipal wastewater before discharge into inland water bodies. The plant has a design capacity of 518.40 cubic meters per day and currently treats an average of 155.52 m³/day, indicating a utilization rate of about 30%. This spare capacity suggests the plant is well-sized for future growth or seasonal fluctuations. The treated effluent is discharged into local waterways that ultimately drain into the Balsas River basin, one of Mexico's major hydrological systems. The Balsas River flows southwest to the Pacific Ocean, supporting diverse aquatic ecosystems and agricultural communities along its course. The plant's operation helps protect downstream water quality in this ecologically and economically important basin.
Environmental context
The plant discharges into the Balsas River basin, which drains into the Pacific Ocean via the Balsas River. This watershed supports a variety of freshwater habitats and is critical for irrigation and drinking water supplies in the region. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain the ecological health of downstream water bodies and prevent eutrophication.
