Crescent WWTP is a municipal wastewater treatment plant located in Crescent, Iowa, United States. The facility serves a small population of 617 residents in this rural community within Pottawattamie County. The plant provides secondary treatment, which is the standard level required under the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 219.55 thousand cubic meters per year and an average discharge volume of 124.92 thousand cubic meters per year, the plant operates below its capacity, indicating room for future growth. The treated effluent is discharged into local waterways that ultimately drain into the Missouri River, a major tributary of the Mississippi River. This downstream connection links the plant to the larger Mississippi River Basin, which supports diverse aquatic ecosystems and provides drinking water for millions of people.

Crescent WWTP discharges into local streams that flow into the Missouri River, which then joins the Mississippi River. The Missouri River supports a variety of fish species and migratory birds, and its water quality is critical for downstream communities. The plant's secondary treatment helps reduce organic pollutants and suspended solids, protecting aquatic life in the receiving waters.
