Colonia Higueras Wastewater Treatment Plant, Cuauhtémoc, Colima, Mexico

Colonia Higueras is a wastewater treatment plant located in Cuauhtémoc, within the state of Colima, Mexico. It serves a population of 1,369 and operates at a secondary treatment level, which is standard for small communities in the region. The plant has a designed capacity of 432.00 m³/day and currently discharges 129.60 m³/day of treated wastewater. As a secondary treatment facility, Colonia Higueras meets the basic requirements under Mexican water quality regulations (NOM-001-SEMARNAT-1996), which set discharge limits for conventional pollutants. The plant's capacity utilization suggests it has room for future growth or seasonal variations. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The treated effluent from Colonia Higueras is discharged into local water bodies that eventually drain into the Pacific Ocean via the Colima coastal basin. The region's hydrology includes rivers and arroyos that flow westward from the Sierra Madre del Sur. The plant plays a role in protecting downstream aquatic ecosystems and groundwater quality in this agricultural and tourist area.

Colonia Higueras is located in the Colima coastal basin, where treated wastewater flows into local streams and rivers that drain into the Pacific Ocean. The region supports diverse aquatic life and is important for migratory birds. The plant's secondary treatment helps reduce organic load and suspended solids, protecting downstream water quality in a semi-arid climate where water resources are seasonally stressed.
