Paticajo Wastewater Treatment Plant, Colima, Mexico

Paticajo wastewater treatment plant is located in the town of Paticajo, within the municipality of Minatitlán, Colima, Mexico. The plant serves a small population of 638 residents, providing essential sanitation services to this rural community. The plant operates with secondary treatment, which is appropriate for its scale. With a designed capacity of 432.00 m³/day and an actual discharge volume of 259.20 m³/day, the facility operates below its capacity. In Mexico, wastewater treatment plants are regulated under the National Water Law and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. The treated effluent is likely discharged into a local watercourse that drains towards the Pacific Ocean, given Colima's coastal location. The plant plays a key role in protecting local water quality and downstream ecosystems, including the coastal waters of the Mexican Pacific.

The plant is located inland in Colima, a state on Mexico's Pacific coast. Treated wastewater likely flows into a local stream or river that eventually reaches the Pacific Ocean. The region supports diverse aquatic life and is part of a broader watershed that includes agricultural and natural areas. Proper treatment helps prevent nutrient pollution and protects coastal ecosystems.
