The treated effluent from Garden City WWTP is discharged into a local water body, likely a tributary of the Arkansas River, which flows through western Kansas. The Arkansas River eventually drains into the Mississippi River system and ultimately the Gulf of Mexico. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from nutrient pollution and pathogens.

The plant discharges into a tributary of the Arkansas River, which flows through the semi-arid High Plains region of Kansas. The Arkansas River is a vital water source for agriculture and wildlife, supporting species such as the Arkansas River shiner. Downstream, the river joins the Mississippi River system, contributing to the Gulf of Mexico's nutrient load. The plant's operations help maintain water quality in this ecologically sensitive basin.
