The hydrants are routinely flushed to clean the distribution system. Residents are advised to avoid or limit water usage during the flushing period and to check for discoloration prior to using water for laundry purposes. It is also recommended that residents shut water off at the meter to avoid drawing in rust, particles, or other debris being flushed from the lines. The flushing is done twice a year, spring and fall. Typically this will be done the last week in April and last week in September, between the hours of 7 p.m. and 5 a.m. Flushing is done by quadrants on 4 separate nights.
