There will be water in the roadway during flushing. Drivers are cautioned to take care when driving through these areas.

The flushing program is essential to the maintenance of the City’s water system and serves a variety of purposes. Flushing of the system each year helps to minimize iron floc build up in the distribution system, verifies the condition and proper operation of fire hydrants and valves, and verifies sufficient water flow for fire suppression.

Residents should complete the following steps after City flushing activities are completed: All residents are recommended to run cold water for 10–15 minutes to clear local lines.Following the cold water process, it is recommended to run hot water for several minutes to further ensure the lines are clear, especially before using washing machines.  Residents with water softeners or whole-house filters should perform a regular maintenance check after City flushing is complete. Residents who experience water discoloration and/or who do not see an improvement after running cold water should call the City of Moscow Water Department at (208) 882-3122, as this may require more localized flushing.  The City of Moscow appreciates and thanks citizens for their patience as this necessary maintenance process is completed. For questions, to report problems, or if water discoloration persists for an extended period, customers may call the Moscow Water Department between 7:00 A.M. and 3:30 P.M. Monday through Friday at (208) 882-3122.###
