Capula Wastewater Treatment Plant, Ixmiquilpan, Hidalgo, Mexico

Capula is a wastewater treatment plant located in the community of Capula, within the municipality of Ixmiquilpan, Hidalgo, Mexico. The plant serves a population of 1,369 and operates with secondary treatment, a standard level for small communities in Mexico under national water quality regulations. The plant has a designed capacity of 172.80 m³/day and currently treats an average daily flow of 129.60 m³/day, indicating it is operating below its full capacity. As a secondary treatment facility, it typically employs biological processes to reduce organic matter and suspended solids before discharge. The treated effluent is discharged into local water bodies that eventually drain into the Gulf of Mexico via the Pánuco River basin. The plant plays a key role in protecting downstream aquatic ecosystems and water quality in the region, supporting both environmental health and community water resources.

The plant discharges into local streams that are part of the Pánuco River basin, which flows eastward to the Gulf of Mexico. This watershed supports diverse aquatic life and provides water for agriculture and communities downstream. The secondary treatment helps reduce nutrient and organic pollution, mitigating eutrophication risks in receiving waters.
