UV disinfection

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.
