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.
