Las Tinas Wastewater Treatment Plant, Sinaloa, Mexico

Las Tinas wastewater treatment plant is located in the small community of Las Tinas, within the municipality of Elota, Sinaloa, Mexico. The plant serves a population of 183, reflecting its role in a rural or peri-urban setting. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant operates with a designed capacity of 69.12 volume units and currently treats a daily volume of 17.28, indicating it is operating well below its capacity. Under Mexican regulations (NOM-001-SEMARNAT-1996), secondary treatment is the standard for municipal wastewater, ensuring compliance with discharge limits for biochemical oxygen demand and total suspended solids. The plant's small scale aligns with the needs of a localized community. The treated effluent is likely discharged into a local watercourse or used for irrigation, contributing to the protection of downstream water bodies. The region's hydrology drains toward the Pacific Ocean, and the plant's operation helps safeguard local water quality and aquatic habitats in the surrounding area.

The plant is located inland in Sinaloa, a state along Mexico's Pacific coast. The treated wastewater likely enters a local stream or arroyo that eventually flows into the Pacific Ocean via the region's river systems. This discharge supports the ecological health of downstream water bodies, including estuaries and coastal zones that host diverse marine life and migratory birds.
