Sewage from Bettendorf and Davenport will undergo enhanced treatment beginning early next year under revised terms of a consent order signed in February with the Iowa Department of Natural Resources (IDNR).

The revised agreement establishes Feb. 28, 2022 as the deadline for adding disinfection treatment, using ultraviolet light, at the Davenport Wastewater Treatment Plant, which handles sewage from Davenport, Bettendorf, Riverdale and Panorama Park.

Bettendorf, Davenport likely to avoid multi-million dollar overflow basin for sewage treatment plant; upgrades have led to lower stormwater infiltration

Owners of the Davenport Waste Water Treatment Plant – the cities of Davenport, Bettendorf, Riverdale and Panorama Park – now appear likely to avoid building a multi-million holding basin designed to handle overflows of sewage and stormwater to the plant during flooding and after heavy rains.

The equalization basin – estimated to cost $25 million back in 2012 – was the most expensive requirement of a 2013 consent agreement between the Iowa Department of Natural Resources (IDNR) and the cities, which jointly operate the treatment facility along the Mississippi River on Concord Street, Davennport.

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.
