The treated effluent from ALLENDALE WWTF is discharged into local waterways that drain into the Missouri River watershed, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting downstream aquatic ecosystems from nutrient pollution and pathogens, supporting the ecological health of the region's rivers and streams.

The plant discharges into local tributaries of the Missouri River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. This watershed supports diverse aquatic life, including fish and macroinvertebrates, and is an important migratory corridor for birds. Secondary treatment reduces organic load and nutrients, helping to prevent eutrophication in downstream waters.
