YUMA WWTP - Secondary Treatment Plant in Yuma, Colorado

YUMA WWTP is a municipal wastewater treatment facility located in Yuma, Colorado, United States. The plant serves a population of approximately 3,500 residents and operates as part of the local infrastructure managed by the city. Its location in the High Plains region of eastern Colorado places it in a semi-arid climate with agricultural surroundings. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater facilities. Under the National Pollutant Discharge Elimination System (NPDES) permitting program, plants of this scale typically must meet effluent limits for biochemical oxygen demand, total suspended solids, and other parameters. The designed capacity of 757.08 megaliters per year indicates the plant's ability to handle peak flows, while the current discharge volume of 567.81 megaliters suggests operational capacity below design. The treated effluent is discharged into a receiving water body, likely a local stream or irrigation canal that drains into the Republican River basin. This waterway ultimately flows into the Mississippi River system and the Gulf of Mexico. The plant plays a key role in protecting local water quality and supporting agricultural reuse in the region.

YUMA WWTP discharges into a watercourse within the Republican River basin, which flows eastward through Nebraska and Kansas before joining the Mississippi River system and eventually the Gulf of Mexico. The local watershed supports agricultural irrigation and provides habitat for aquatic species. The plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to downstream eutrophication in reservoirs and the Gulf of Mexico hypoxic zone.
