Water System Flushing 

Drinking Water Main Flushing

The City of Monroe is committed to providing the very best drinking water possible. Each year the City conducts a thorough water main flushing program. The program is designed to scour water mains of sediment and mineral build up throughout the distribution system, as well as verify proper operation of the valves and hydrants within the Monroe water distribution system.

As a result of this flushing program, you may experience some of the following short-term minimal inconveniences:

  • Fluctuating water pressure
  • Air in the lines
  • Cloudy water or turbidity

The following link shows the flushing map for 2022 with anticipated months of impact.

To stop these disturbances you may be required to run your water for a few minutes in order to clear your lines. If this procedure fails, and you continue to experience the listed disturbances, please visit Monroe Listens or call 360-794-7400 during normal business hours.
