La Despensa Wastewater Treatment Plant, Ahome, Sinaloa, Mexico

La Despensa wastewater treatment plant is located in the town of La Despensa, within the municipality of Ahome, Sinaloa, Mexico. The plant serves a population of 2,008 people, providing secondary treatment to municipal wastewater. It operates as part of the local water infrastructure managed by the state water authority. The plant has a designed capacity of 216.00 cubic meters per day and currently treats an average daily flow of 190.08 cubic meters, indicating it is operating below its full capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, meeting Mexican regulatory standards for wastewater discharge (NOM-001-SEMARNAT-1996). The treated effluent is discharged into the local watershed, which ultimately drains into the Gulf of California. The region's water bodies support diverse aquatic life and are important for local fisheries and agriculture. Proper treatment helps protect downstream ecosystems and public health.

The plant discharges into the local drainage network that flows into the Gulf of California, a biologically rich marine environment. The Gulf supports diverse species including fish, crustaceans, and migratory birds. Secondary treatment reduces organic pollutants and nutrients, helping to prevent eutrophication and maintain water quality in downstream coastal habitats.
