sewage treatment plant

Bettendorf, Riverdale and Panorama Park sewage was flushed into the Mississippi River between April 29 and May 9.

The City of Bettendorf pumped 179 million gallons of untreated sewage mixed with stormwater runoff into the river, according to reports filed with the Iowa Department of Natural Resources. Neither the city or the state estimate how much actual sewage is pumped directly into the river as a result of such "Sanitary Sewer Overflows" (SSO's).
