Overview
Coyotitan wastewater treatment plant in Sinaloa, Mexico, serves 1,660 people with secondary treatment. It discharges 328.32 cubic meters of treated wastewater daily.
Coyotitan wastewater treatment plant is located in the town of Coyotitan, within the municipality of San Ignacio, Sinaloa, Mexico. The facility serves a population of approximately 1,660 residents, reflecting its role as a small-scale municipal treatment system in a rural coastal region. The plant provides secondary treatment, which is the standard biological treatment level required under Mexican regulations (NOM-001-SEMARNAT) for municipal wastewater. It has a designed capacity of 328.32 cubic meters per day and discharges a similar volume, indicating full utilization. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local water bodies that ultimately drain into the Pacific Ocean via the Sinaloa coastal watershed. The region's semi-arid climate and proximity to the coast make proper wastewater treatment essential for protecting downstream aquatic ecosystems and coastal water quality.
Environmental context
The plant discharges into the Sinaloa coastal basin, which drains into the Pacific Ocean. This watershed supports diverse aquatic life and is important for local fisheries. Proper treatment helps prevent nutrient enrichment and pathogen contamination in downstream estuaries and coastal waters, which are ecologically sensitive areas.
