Tepuche Wastewater Treatment Plant, El Tepuche, Sinaloa, Mexico

The Tepuche wastewater treatment plant is located in El Tepuche, a locality within the municipality of Culiacán in the state of Sinaloa, Mexico. It serves a population of approximately 1,825 residents, providing secondary treatment to manage domestic wastewater from the community. The plant operates with a designed capacity of 345.60 cubic meters per day and currently treats an average discharge volume of 172.80 cubic meters per day, indicating a utilization rate of about 50%. As a secondary treatment facility, it meets the standard requirements for municipal wastewater treatment in Mexico, which are regulated under the national water law (Ley de Aguas Nacionales) and overseen by the National Water Commission (CONAGUA). The treated effluent from the plant is discharged into the local environment, ultimately contributing to the Culiacán River basin, which flows into the Pacific Ocean via the Gulf of California. The region's water resources support agriculture and local ecosystems, making proper wastewater treatment essential for protecting downstream water quality and aquatic life.

The plant discharges into the Culiacán River basin, which drains into the Gulf of California, a biologically rich marine ecosystem. The downstream environment includes agricultural areas and wetlands that depend on clean water. Proper treatment helps prevent nutrient loading and contamination that could harm fish populations and migratory bird habitats in the region.
