El Corazon Wastewater Treatment Plant, Miguel Valdez Quintero, Sinaloa

El Corazon is a wastewater treatment plant located in Miguel Valdez Quintero (El Corazón), a locality within the municipality of Culiacán, Sinaloa, Mexico. The plant serves a population of approximately 3,000 residents, providing secondary treatment to manage domestic wastewater from this small coastal community. With a designed capacity of 354.24 cubic meters per day, the plant operates at full capacity based on reported discharge volumes. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, meeting standard requirements for such facilities in Mexico under the national water quality regulations (NOM-001-SEMARNAT). The plant is situated within 10 kilometers of the Pacific coast, indicating that treated effluent likely discharges into a nearby watercourse that flows into the ocean. This proximity to the coast underscores the importance of effective treatment to protect marine ecosystems and coastal water quality in the Gulf of California region.

The plant discharges into a local watercourse that drains into the Pacific Ocean near the Gulf of California. This coastal region supports diverse marine life, including fish, crustaceans, and migratory birds. Effective secondary treatment is crucial to prevent nutrient loading and pathogen contamination that could harm nearshore habitats and fisheries.
