storm water runoff

Bettendorf pumped 18.4 million gallons of untreated sewage mixed with storm water into the Mississippi River over a four-day period earlier this month after heavy rain and high water clogged the main interceptor along the riverfront and flows overwhelmed the treatment capacity of the Davenport/Bettendorf sewage treatment plant.

Pumps along the riverfront operated from June 14 through June 18, transferring back-up in the sewer lines into storm water pipes that empty into the river.
