Tacuichamona Wastewater Treatment Plant, San Francisco de Tacuichamona, Sinaloa

Tacuichamona is a wastewater treatment plant located in San Francisco de Tacuichamona, a locality in the municipality of Culiacán, Sinaloa, Mexico. The plant serves a population of approximately 1,719 people, reflecting its role in managing domestic wastewater for a small community in northwestern Mexico. The plant provides secondary treatment, a standard level for municipal wastewater in Mexico, which typically involves biological processes to reduce organic matter and suspended solids. With a designed capacity of 354.24 cubic meters per day and a current discharge volume of 345.60 cubic meters per day, the facility operates near its capacity. Mexican wastewater treatment plants are regulated under the Federal Law for Water and the National Water Commission (CONAGUA), which sets discharge standards to protect water quality. The treated effluent is discharged into the local watershed, which ultimately drains into the Pacific Ocean via the Culiacán River system. This region supports diverse aquatic life and agricultural activities, making proper wastewater treatment essential for maintaining downstream water quality and ecosystem health.

The plant's discharge enters the Culiacán River basin, which flows through the state of Sinaloa and empties into the Pacific Ocean near the city of Culiacán. This watershed supports irrigated agriculture and estuarine habitats that are important for migratory birds and marine species. Effective secondary treatment helps reduce nutrient loading and organic pollution, protecting downstream water quality and the ecological balance of the coastal zone.
