Felipe Angeles Wastewater Treatment Plant, Sinaloa, Mexico

The Felipe Angeles wastewater treatment plant is located in the town of Felipe Angeles, within the municipality of Ahome, Sinaloa, Mexico. This facility serves a population of 1,917 residents, providing secondary treatment for municipal wastewater. The plant has a designed capacity of 216.00 m³/day and currently discharges 181.44 m³/day of treated effluent. As a secondary treatment plant, it meets the standard level of treatment required for municipal wastewater in Mexico under the national water quality regulations (NOM-001-SEMARNAT). For a small agglomeration of under 2,000 people, secondary treatment is appropriate to reduce organic matter and suspended solids before discharge. It functions as part of the local sanitation infrastructure. The treated effluent from the plant is discharged into the local environment, likely into a nearby watercourse or drainage system that eventually flows into the Gulf of California. The region is part of the Pacific coastal watershed, and the discharge contributes to the water quality of downstream ecosystems. Proper treatment helps protect aquatic life and supports the ecological health of the receiving waters.

The plant discharges into a local watercourse that drains into the Gulf of California, a biologically rich marine environment. The Gulf supports diverse fisheries and migratory species. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in the downstream ecosystem. The region's arid climate means water resources are limited, making effective treatment important for both human use and ecological balance.
