Cofradía de la Loma Wastewater Treatment Plant, Sinaloa, Mexico

Cofradía de la Loma is a wastewater treatment plant located in the town of Cofradía de la Loma, within the municipality of Navolato, Sinaloa, Mexico. The plant serves a population of 1,825 residents, providing secondary treatment to manage domestic wastewater from this small agglomeration. As a secondary treatment facility, the plant meets the standard level of treatment required for municipal wastewater in Mexico under the national water law (Ley de Aguas Nacionales) and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. The plant has a designed capacity of 181.44 cubic meters per day and currently discharges 172.80 cubic meters per day, indicating it operates near its intended capacity. The treated effluent is discharged into the local environment, likely into a nearby watercourse that drains into the Pacific Ocean via the Gulf of California. The region's water resources support agriculture and local ecosystems, making proper wastewater treatment important for protecting downstream water quality and aquatic life.

The plant is located inland in Sinaloa, within 50 km of the coast, and its treated effluent likely flows into a tributary of the Río Culiacán or a similar coastal basin, eventually reaching the Gulf of California. This region supports diverse aquatic habitats, including mangrove estuaries and coastal lagoons, which are sensitive to nutrient loading and require effective wastewater treatment to maintain ecological balance.
