Camalote Wastewater Treatment Plant, El Camalote, Sinaloa, Mexico

Camalote is a wastewater treatment plant located in El Camalote, a locality within the municipality of Culiacán, Sinaloa, Mexico. The plant serves a population of approximately 2,738 people, making it a small-scale facility in the region. It is situated inland, more than 10 km from the coast, and its operations are part of the municipal wastewater infrastructure for the area. The plant provides secondary treatment, which is the standard biological treatment required under Mexican regulations (NOM-001-SEMARNAT) for municipal wastewater. The designed capacity is 354.24 cubic meters per day, with a current discharge volume of 259.20 cubic meters per day, indicating it operates below its full capacity. As a secondary treatment facility, it effectively reduces organic matter and suspended solids before discharge. The treated effluent is discharged into the local watershed, which ultimately drains into the Pacific Ocean via the Culiacán River basin. The plant plays a key role in protecting downstream water quality and aquatic ecosystems in the region, supporting both environmental and public health objectives.

The plant discharges into the Culiacán River basin, which flows through the state of Sinaloa and empties into the Pacific Ocean. This watershed supports diverse aquatic life and is important for local agriculture and fisheries. The secondary treatment provided by the plant helps reduce nutrient and pollutant loads, mitigating eutrophication risks in downstream water bodies and coastal areas.
