Bettendorf, Riverdale, Panorama Park sewage pumped into Mississippi River for 14 days

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).

Heavy rains prompt additional sewage overflows; sewage treatment plant once again over capacity

Heavy rain in November and December prompted yet another series of "sanitary sewer overflow (SSO) events" in Bettendorf, resulting in more than 17 million gallons of untreated sewage and storm water being pumped into the Mississippi River.

With the additional sewage bypasses in the last two months of the year, Bettendorf operated pumps along the riverfront a total of 15 days during 2015 and dumped a total of more than 46 million gallons of the storm water and raw sewage into the river.
