Zavala is a municipal wastewater treatment plant located in the town of Zavala, within the municipality of Concordia, Sinaloa, Mexico. The facility serves a population of approximately 1,460 residents, classifying it as a small-scale treatment plant typical of rural communities in the region. The plant provides secondary treatment, which is the standard biological treatment process required under Mexican regulations (NOM-001-SEMARNAT-1996) for municipal wastewater before discharge. With a design capacity of 164.16 cubic meters per day and an actual discharge volume of 138.24 m³/day, the plant operates at about 84% capacity, indicating it is functioning within its designed load. The treated effluent is discharged into a local watercourse that eventually drains into the Pacific Ocean via the Presidio River basin. The plant's location more than 10 km from the coast reduces direct marine impact, but its proximity to the river system means proper treatment is essential to protect downstream aquatic ecosystems and coastal water quality.
Environmental context
The plant discharges into the Presidio River basin, which flows westward through Sinaloa and empties into the Pacific Ocean near Mazatlán. This watershed supports diverse aquatic life and is important for local fisheries and agriculture. The secondary treatment provided helps reduce organic pollutants and suspended solids, protecting the river's ecological health and the coastal zone from nutrient enrichment.
