Colonia Agrícola Sinaloa Wastewater Treatment Plant, Sinaloa, Mexico

Colonia Agrícola Sinaloa is a wastewater treatment plant located in the town of Colonia Agrícola Sinaloa, within the municipality of Angostura, Sinaloa, Mexico. The plant serves a population of approximately 1,095 residents, making it a small-scale facility in the region. Its location near the Pacific coast places it in an environmentally sensitive area where proper wastewater management is critical. The plant provides secondary treatment, which is the standard biological treatment process that removes organic matter and suspended solids. With a designed capacity of 112.32 cubic meters per day and a discharge volume of 103.68 cubic meters per day, it operates at a high utilization rate. Under Mexico's national water regulations (NOM-001-SEMARNAT), secondary treatment is required for discharges into coastal waters, ensuring compliance with environmental standards. The treated effluent is discharged into the local environment, likely reaching the Pacific Ocean via nearby estuaries or coastal lagoons. The region's coastal ecosystems, including mangroves and marine habitats, depend on controlled discharges to prevent nutrient overload and protect biodiversity. The plant plays a key role in safeguarding water quality in this agricultural and coastal area.

The plant discharges treated wastewater into the coastal zone of Sinaloa, which ultimately drains into the Pacific Ocean. This area supports diverse marine life and is part of a larger coastal ecosystem that includes estuaries and wetlands. Proper treatment is essential to prevent eutrophication and protect fisheries and tourism in the region.
