Why We Flush Hydrants
Under our flushing program, fire hydrants are opened in order to remove any sediments that may have collected within our pipes to ensure that you always have the highest quality water. The program also allows us to check to make sure that hydrants function properly and that a sufficient water supply is available for fire protection.
Notice Regarding Discolored Water Flushing operations close to your home may be responsible for temporary lower water pressure, discolored water and/or water collecting in the street. Rusty or discolored water is a result of natural iron and other solid matter being stirred up—it is not harmful to your health and typically lasts only for the day work is conducted.
If you experience discolored water and your laundry is stained as a result, try rewashing the clothes using more detergent and add rust remover. It is not advisable to attempt to bleach clothes or put them in the dryer.
