Wastewater is the water we flush down the drain after use in our homes and businesses. The wastewater travels through underground sanitary sewer pipes until it reaches the Wastewater Treatment Plant. When wastewater reaches the plant it goes through a series of processes to remove waste and harmful pathogens, so the water can be safely returned to the river environment. Downstream users will clean the water for drinking, cooking and bathing and then recycle it all over again.

The City of Davenport Water Pollution Control Plant is one of the largest Wastewater Treatment plants in the State of Iowa, serving the cities of Davenport, Bettendorf, Panorama Park and Riverdale.

As a Grade IV activated sludge plant, it consists of preliminary, primary and secondary treatment of wastewater with digestion and composting of the biosolids that are produced.

The annual average wastewater flow through the plant in 2015 was 26.8 million gallons per day (MGD); during heavy rains, or flooding situations, the flow can reach 60 MGD. The incoming wastewater in 2015 contained an average of 160 mg/l of BOD and 183 mg/l of TSS. The outgoing effluent averaged 6 mg/l of CBOD and 9 mg/l of TSS.
