PULASKI WWTP - Secondary Wastewater Treatment in Pulaski, Iowa

PULASKI WWTP is a municipal wastewater treatment facility located on Mill Street in Pulaski, Davis County, Iowa. It serves a small population of 221 residents, reflecting the rural character of the area. The plant operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. Its designed capacity is 98.42 volume units, with a current discharge volume matching that figure. As a small facility, it is subject to state-level NPDES permitting administered by the Iowa Department of Natural Resources, ensuring compliance with water quality standards. The treated effluent is discharged to a local water body that ultimately drains into the Mississippi River basin. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's operation helps protect local streams from nutrient pollution and pathogen contamination, contributing to the ecological health of the region.

The plant discharges into a tributary of the Des Moines River, which flows southeast to join the Mississippi River near Keokuk. This reach of the Mississippi River basin supports diverse fish populations and migratory birds. The plant's secondary treatment reduces organic load and suspended solids, helping maintain water quality in a region dominated by agriculture, where nutrient runoff is a concern.
