sanitary sewer overflow

20 days, 10 pumps and 448 million gallons of sewage-contaminated water flushed into Mississippi

For 20 days beginning May 27, Bettendorf continuously ran 10 pumps along its riverfront to flush 448 million gallons of sewage-contaminated water into the Mississippi River.

The latest Sanitary Sewer Overflow (SSO) "Event" was again the result of rain and flood water clogging the main sewer interceptor line to the Davenport Waste Water Treatment Plant.

To prevent the treatment plant was being inundated with the huge flows and avoid sewage back-ups to businesses and homes along the Bettendorf/Riverdale riverfront, gates to the main sewer line were closed May 27.
