Delta WWTP discharges into a receiving water body within the Colorado River basin, which ultimately flows to the Gulf of California. The Colorado River is a vital water source for millions of people and supports diverse aquatic and riparian habitats.

The plant's effluent must meet state and federal standards to protect these resources.
