The flushing program may cause periods of discolored water and reduced water pressure in localized areas where flushing is being conducted. The discoloration is due to particles and minerals that have settled in the water main being mobilized by the high velocity water before being discharged through the flowing fire hydrants. The water will remain safe to use and generally clears within a few hours after flushing has been completed. Residents should monitor their water prior to starting laundry, especially when washing white clothes. Due to temporary reductions in water pressure in the vicinity of flushing operations, the reduced pressures may cause low-pressure alarms to activate on automatic fire sprinkler systems for commercial properties.
