The Burlington Municipal Waterworks will begin their annual flushing of city fire hydrants beginning the first week of September and will continue for approximately 5-6 weeks. During this time residents may experience temporary low pressures 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.
