San Juan Tecomatlán wastewater treatment plant is located in the town of San Juan Tecomatlán, within the municipality of Poncitlán in the Región Ciénega of Jalisco, Mexico. The plant serves a population of 2,669 and operates with secondary treatment, a standard level for communities of this size in Mexico. The plant has a designed capacity of 345.60 cubic meters per day and discharges a similar volume of treated wastewater. Under Mexican regulations (NOM-001-SEMARNAT), secondary treatment is required to meet discharge standards for organic matter and suspended solids. The plant's coastal proximity means it must also comply with additional standards for marine discharge. The treated effluent likely drains into the Lerma-Chapala basin, which feeds Lake Chapala, Mexico's largest freshwater lake. This watershed supports diverse aquatic life and provides water for irrigation and drinking. Proper treatment is critical to prevent nutrient pollution and protect the lake's ecological health.
Environmental context
The plant discharges into the Lerma-Chapala watershed, which ultimately drains into Lake Chapala, a vital freshwater resource in western Mexico. Lake Chapala supports a rich ecosystem of fish and migratory birds and is a key water source for the Guadalajara metropolitan area. The plant's coastal proximity (within 10 km) means its discharge may also affect coastal lagoons and the Pacific Ocean via the Santiago River system. Effective secondary treatment helps control nutrient loads and protects downstream aquatic habitats.
