Yebavito Wastewater Treatment Plant, Sinaloa, Mexico

Yebavito wastewater treatment plant is located in the town of Yebavito, within the municipality of Navolato, Sinaloa, Mexico. The facility serves a population of about 1,825 people, reflecting a small-scale municipal wastewater operation typical of rural communities in the region. The plant provides secondary treatment, a standard level for small agglomerations under Mexican regulations (NOM-001-SEMARNAT-1996). It treats an average of 172.80 cubic meters per day, operating below its designed capacity of 190.08 m³/day, indicating adequate hydraulic capacity for current loads. The treated effluent is discharged into local watercourses that eventually drain into the Pacific Ocean via the Gulf of California. The plant plays a key role in protecting downstream aquatic ecosystems and coastal waters from untreated sewage, supporting water quality in the region's agricultural and estuarine environments.

The plant's discharge enters local drainage networks that flow into the Gulf of California, a biologically rich sea supporting diverse marine life including fisheries and migratory species. The region's watershed is influenced by agricultural runoff and seasonal rainfall, making effective wastewater treatment critical for maintaining water quality in downstream estuaries and coastal habitats.
