Tinajas Wastewater Treatment Plant | Colima, Mexico

Tinajas is a municipal wastewater treatment plant located in the town of Tinajas, within the municipality of Colima, Colima, Mexico. The facility serves a small population of 456 residents, reflecting its role in a rural or peri-urban setting. As a secondary treatment plant, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant has a designed capacity of 86.40 volume units and currently treats 43.20 volume units daily, indicating a utilization rate of 50%. Under Mexican water regulations (NOM-001-SEMARNAT-1996 and subsequent updates), secondary treatment is the standard for municipal wastewater, ensuring compliance with discharge limits for biochemical oxygen demand and total suspended solids. Its active discharge volume suggests ongoing operation. Treated effluent from Tinajas likely discharges into a local watercourse that drains into the Pacific Ocean via the Armería River basin or nearby coastal lagoons. The region's tropical climate and agricultural activity make proper wastewater treatment essential for protecting downstream water quality and aquatic ecosystems. The plant contributes to reducing pollution loads in the Colima watershed, supporting both environmental health and community well-being.

Tinajas lies in the state of Colima, within the Pacific coastal watershed of western Mexico. The nearest major river is the Armería River, which flows into the Pacific Ocean near the city of Tecomán. The receiving water body for the plant's effluent is likely a small stream or arroyo that feeds into the Armería basin. This region supports diverse aquatic life, including fish and migratory birds, and the coastal zone features important mangrove and estuary habitats. Proper treatment helps prevent eutrophication and protects downstream ecosystems from untreated sewage.
