During this time residents may experience temporary low pressures and/or discolored water. If discolored water is experienced, the Waterworks suggests residents let their cold water run in a sink or bathtub, capable of draining the flow, for up to 20 minutes. If the problem still persists, please notify the Waterworks Office at (319)754-6501, or after hours, notify the Water Treatment Plant at (319)752-7611. For those customers with a water meter, letting the water run will increase the amount of your bill. Additionally, customers may notice a slight chlorine odor as the Waterworks will be disinfecting with free chlorine during the flushing process and returning to chloramines for disinfecting when finished.
