Village of Pewaukee Water Main Flushing
The Village of Pewaukee routinely flushes the water main distribution system within the Village to help improve and maintain long-term water quality and to minimize discoloration and odors. Historically the flushing of mains has been scheduled in late summer/early fall.
Why Water Main Flushing is Important
Although the water within the Village distribution system is of very high quality, the aesthetic quality can deteriorate over time if the mains are not properly managed. The flushing process removes sediment and mineral deposits which naturally begin to build up in the mains over time. The removal is accomplished by “scouring” the mains by running water through them at high velocity and discharging it through fire hydrants.
What Residents Should Know
As a result of water main flushing, residents may experience a reduction in water pressure when the crew is flushing the main immediately adjacent to their home or business. The pressure will return to normal once the flushing in the immediate area is completed.
While the vast majority of mineral deposits are discharged through the fire hydrants during the flushing process, small amounts can remain within the system once the work is completed. As a result, residents may also experience cloudy or rusty-colored water when they first turn on their faucet. Although the discolored water is safe and does not pose a health concern, residents are strongly encouraged to check their water prior to doing laundry or other projects in which discolored water could be a problem. Residents who experience discolored water are advised to run cold water through a non-aerated faucet, such as a bathtub or exterior water spigot, for 5 to 10 minutes until the water becomes clear. Residents are also advised to avoid using hot water before checking the cold water to prevent discolored water from entering their hot water heater.
