Laguna de Lourdes Wastewater Treatment Plant, San Juan del Río, Querétaro

Laguna de Lourdes is a wastewater treatment plant located in San Juan del Río, Querétaro, Mexico. It serves a small population of 1,123 residents, reflecting its role in a localized community within the state's wastewater infrastructure. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 432 cubic meters per day and an actual discharge volume of 106.27 cubic meters per day, the plant operates well below its capacity. Mexican regulations under NOM-001-SEMARNAT-1996 set discharge limits for pollutants, and secondary treatment typically meets these standards for municipal wastewater. The treated effluent is discharged into the local watershed, which ultimately drains into the Pánuco River basin and flows toward the Gulf of Mexico. The plant's operation helps protect downstream water quality and aquatic ecosystems in the region.

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 agriculture and communities downstream. Proper treatment is essential to prevent nutrient pollution and maintain ecological balance in the river system.
