Cabecera Municipal Wastewater Treatment Plant, Ciudad de Jocotitlán, Estado de México

Cabecera Municipal is a wastewater treatment plant located in Ciudad de Jocotitlán, within the Estado de México region of Mexico. It serves a population of approximately 22,880 residents, classifying it as a medium-sized agglomeration under Mexican wastewater regulations. The plant is situated inland, more than 50 km from the coast, and its operations are part of the municipal infrastructure managed by local authorities. As a plant serving a community of this scale, it is expected to comply with Mexico's national wastewater standards (NOM-001-SEMARNAT-1996 and subsequent updates), which mandate treatment levels based on the receiving water body's sensitivity. Typical plants in this region employ secondary treatment technologies such as activated sludge or stabilization ponds to meet discharge requirements. The treated effluent from Cabecera Municipal likely discharges into local watercourses that drain into the Lerma River basin, which flows westward into Lake Chapala, Mexico's largest freshwater lake. This watershed supports diverse aquatic life and provides water for agriculture and human consumption downstream. Proper treatment is essential to protect these ecological and water supply resources.

The plant's discharge likely enters the Lerma River basin, which flows into Lake Chapala, a critical freshwater resource for the region. The watershed supports diverse aquatic ecosystems and provides water for irrigation and drinking water for millions of people. Protecting water quality in this basin is vital for maintaining ecological balance and public health.
