Reciclagua Wastewater Treatment Plant, Lerma de Villada, Estado de México

Reciclagua is a municipal wastewater treatment plant located in Lerma de Villada, within the Estado de México, Mexico. It serves a population of 424,810, classifying it as a large agglomeration under Mexican water management standards. The plant is situated inland, approximately 50 km from the coast, and its operations are integral to the region's sanitation infrastructure. As a large-scale facility, Reciclagua is expected to comply with Mexico's official standards for wastewater treatment, which typically require secondary treatment or higher for such population tiers. Regulatory frameworks for this scale often mandate advanced treatment to protect receiving water bodies. The plant discharges treated wastewater into local watercourses that ultimately drain into the Lerma River basin, a critical hydrological system in central Mexico. The Lerma River flows into Lake Chapala, Mexico's largest freshwater lake, which supports diverse aquatic life and provides water for agriculture and human consumption. Proper treatment at Reciclagua is essential to prevent nutrient loading and contamination in this ecologically sensitive watershed.

Reciclagua's treated effluent enters the Lerma River basin, which flows into Lake Chapala, the largest freshwater lake in Mexico. This watershed supports a rich diversity of aquatic species and is a vital resource for regional agriculture and drinking water. The lake's ecological health depends on controlling nutrient inputs and pollutants from upstream sources, making effective wastewater treatment at plants like Reciclagua crucial for maintaining water quality and ecosystem balance.
