Campo Eureka Wastewater Treatment Plant, Sinaloa, Mexico

Campo Eureka is a municipal wastewater treatment plant located in the town of Campo Eureka, within the municipality of Culiacán, Sinaloa, Mexico. The plant serves a small population of approximately 1,004 residents, reflecting its role in a rural or peri-urban community. Its coastal proximity places it within a sensitive environmental zone where treated effluent management is critical. The plant operates with secondary treatment, which is the standard level required under Mexican regulations (NOM-001-SEMARNAT-1996) for discharge into coastal waters. It has a designed capacity of 95.04 cubic meters per day, matching the reported discharge volume, indicating full utilization. As a small facility, it is part of Mexico's decentralized wastewater infrastructure, often managed by local water utilities or municipal governments. The treated effluent from Campo Eureka likely discharges into a nearby watercourse or directly into the Pacific Ocean via the coastal drainage system of Sinaloa. The region's watershed includes the Culiacán River basin, which supports agriculture and estuarine habitats. Proper treatment helps protect coastal ecosystems and public health in this area of northwestern Mexico.

Campo Eureka lies within the coastal plain of Sinaloa, near the Pacific Ocean. The local watershed drains through the Culiacán River basin, which empties into the Gulf of California. This coastal zone supports diverse marine life, including fisheries and migratory birds. Secondary treatment reduces organic pollutants and suspended solids, mitigating eutrophication risks in the receiving waters. The plant's proximity to the coast underscores the importance of effective nutrient removal to protect downstream ecosystems.
