Baila Wastewater Treatment Plant, Culiacán, Sinaloa, Mexico

Baila wastewater treatment plant is located in the town of Baila, within the municipality of Culiacán, Sinaloa, Mexico. The plant serves a population of approximately 976 people, making it a small-scale facility in a rural or peri-urban setting. Its location near the Pacific coast places it in an environmentally sensitive zone where proper wastewater management is critical. The plant provides secondary treatment, which is the standard biological treatment required under Mexican regulations (NOM-001-SEMARNAT) for municipal wastewater. With a designed capacity of 129.60 m³/day and an actual discharge volume of 120.96 m³/day, the facility operates at high utilization. The treated effluent is discharged into the local environment, likely into a nearby watercourse that drains into the Pacific Ocean. Given the coastal proximity, the plant plays a key role in protecting downstream marine ecosystems, including estuaries and coastal waters that support diverse aquatic life and local fisheries.

The plant discharges into a local water body that ultimately flows into the Pacific Ocean near the coast of Sinaloa. This region features important coastal lagoons and mangrove ecosystems that provide nursery habitat for fish and shellfish. Proper treatment helps prevent nutrient pollution and pathogen contamination, safeguarding both ecological health and human uses such as fishing and recreation.
