Rochester Public Utilities recommends businesses flush internal water systems prior to re-opening

MN businesses are getting ready to re-open their doors after the statewide Stay-at-Home order concludes. 

The Centers for Disease Control and Prevention has released guidelines reminding business owners that internal water systems should be flushed prior to re-opening buildings and facilities after this period of prolonged shutdown.

Internal water system flushing is important maintenance that should be used any time a building has been closed for an extended period to maintain good water quality. Flushing water lines removes older water and ensures that you have the freshest, best quality water prior to re-opening.

Flushing an internal water system includes flushing hot and cold water through all points (e.g. showers, sink faucets) and flushing hot water until it reaches maximum temperature.

Rochester Public Utilities (RPU) is reminding area business owners to complete this system maintenance prior to re-opening their doors to maintain public health after this period of prolonged shutdown. RPU continues to flush the water distribution system throughout the city to make sure that when building owners flush their own buildings, they will get the freshest water possible from our water mains.
