Plant Operations

Operators


The Muscatine Water & Resource Recovery Facility (formerly the Water Pollution Control Plant) has five (5) certified operators that run and maintain the plant 12 hours a day. Operations, maintenance, and laboratory staff work together to keep the plant within state regulations of a National Pollutant Discharge Elimination System (NPDES) permit.

Treatment Processes


Originally, publicly owned treatment works (POTW) were designed to treat domestic sewage only. However, our POTW also receives wastewater from industrial (non-domestic) users. Muscatine is required by the U.S. Environmental Protection Agency and the Iowa Department of Natural Resources to implement a Pretreatment Program to control pollutants from the industrial users which may pass through or interfere with POTW treatment processes or which may contaminate biosolids.

Pretreatment Program


The pretreatment program helps the plant keep the water discharge within the regulations of the NPDES permit that is required by the EPA. The influent (incoming wastewater) and effluent (treated wastewater) is tested by the plant's certified laboratory. The Muscatine WRRF Laboratory works with Plant Operations to maintain the plant and keep the plant operating within the permit.

Pumping Stations


The WRRF maintains 21 pumping stations. Pumping stations pump the wastewater from the collection system to the WRRF. Pumping stations have electrical and mechanical controls that are maintained on a daily basis.
