Huitussi y Anexos Wastewater Treatment Plant - El Huitussi y Anexos, Sinaloa, Mexico

Huitussi y Anexos is a wastewater treatment plant located in the locality of El Huitussi y Anexos (El Huitussito), within the municipality of Guasave, Sinaloa, Mexico. The plant serves a population of 1,369 and is part of the municipal wastewater infrastructure for this small community. The plant provides secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT-1996) for discharges into water bodies. With a designed capacity of 138.24 m³/day and an actual discharge volume of 129.60 m³/day, the plant operates at approximately 94% capacity. This indicates consistent operation to meet local wastewater treatment needs. The treated effluent is discharged into local watercourses that eventually drain into the Pacific Ocean via the Sinaloa River system. The region's semi-arid climate and agricultural activities make proper wastewater treatment essential for protecting downstream water quality and supporting local ecosystems.

The plant discharges into the Sinaloa River basin, which flows westward through the state of Sinaloa and empties into the Gulf of California (Sea of Cortez). This coastal ecosystem supports diverse marine life, including shrimp and fish species important for local fisheries. Secondary treatment helps reduce organic pollutants and suspended solids, mitigating impacts on the riverine and coastal environments.
