Davenport/Bettendorf get 4-month extension on sewage treatment plant's UV disinfection plans

Iowa environmental officials have okayed a four-month extension for the Davenport Wastewater Treatment Plant to finalize plans for ultraviolet (UV) disinfection of the facility's effluent.

Under terms of a 2014 administrative consent order, the treatment facility (which handles sewage from Davenport, Bettendorf, Riverdale and Panorama Park) agreed to add the UV treatment to kill bacteria before the effluent is pumped into the Mississippi River.

The UV disinfection plans were to be finalized and submitted to the Iowa Department of Natural Resources (IDNR) by August 31, but flooding delayed the pilot testing of the proposed equipment for the project, plant officials wrote the IDNR in early August.

Last week, the IDNR agreed to allow the deadline to be pushed back until Jan. 15 of next year.
