Shakopee Public Utilities uses the unidirectional flushing method. We control the direction of the water flowing through the mains by changing the valving in the street instead of just opening a hydrant and letting it flow. In this way we can scour the mains in two directions to remove the maximum amount of sediments and minerals. This method of flushing will use less water and remove more aesthetically undesirable minerals such as iron and manganese. Flushing can also save money on chemicals. Some of the minerals that cling to the walls of the watermains can also reduce the amount of chlorine in the water that is necessary to prevent harmful bacteria. By keeping our watermains clean we will not need to add additional chlorine to the system. Our flushing season is from April until November. We will place signs at the major entrances to a neighborhood a few days prior to flushing. Flushing will take place between 8:00am and Noon. While these signs are up it is advisable that you make sure your water is clear before washing any light-colored clothing. Simply run some water into a clear glass to see if there is any discoloration. If you have any questions about our flushing program please call 952-233-1503.
