The surrounding watershed supports agricultural activities and diverse aquatic life, making proper wastewater treatment essential for protecting downstream ecosystems.

The plant is situated in the Sinaloa region, where water bodies drain into the Pacific Ocean via the Gulf of California. The local watershed supports agriculture and fisheries, and the treated effluent contributes to maintaining water quality in downstream rivers and coastal areas. Proper secondary treatment helps reduce nutrient loading and protects sensitive aquatic habitats from eutrophication.
