Abuya y Ceuta II Wastewater Treatment Plant, Culiacán, Sinaloa, Mexico

Abuya y Ceuta II is a wastewater treatment plant located in the community of Abuya y Ceuta Segunda (Ejido Echeverría), within the municipality of Culiacán, Sinaloa, Mexico. The plant serves a population of 1,303 and operates with secondary treatment, a standard level for small communities under Mexican regulations (NOM-001-SEMARNAT-1996). The plant has a designed capacity of 267.84 cubic meters per day and discharges a similar volume of treated wastewater. As a secondary treatment facility, it removes organic matter and suspended solids, meeting typical effluent quality standards for discharge into water bodies. The plant's operation is part of Mexico's national water infrastructure managed by CONAGUA. The treated effluent is discharged into local waterways that drain into the Pacific Ocean, given the plant's proximity to the coast (within 10 km). The surrounding region includes agricultural areas and coastal ecosystems, making proper wastewater treatment important for protecting downstream water quality and marine habitats.

The plant discharges into local streams that flow into the Pacific Ocean near the coast of Sinaloa. This coastal region supports diverse marine life and is part of the Gulf of California watershed, an ecologically productive area. Proper treatment helps prevent nutrient pollution and protects coastal ecosystems, including mangroves and estuaries that serve as nurseries for fish and migratory birds.
