Hydrant Flushing to Begin Monday

Post Date:05/15/2018 10:37 AM

The Utilities Division of the City of Sioux City will begin flushing fire hydrants beginning Monday, May 21, 2018. This program is a necessary distribution system maintenance function in which sediment is expelled from the distribution system by opening fire hydrants and allowing them to flow until the water appears clear. The Utilities Division is starting a source point flushing, which will start at the water plants and work out. This will be starting on Gordon Drive going North, with work between Lewis Blvd. and Hwy. 75.  Additional press releases will be shared for new areas as work continues.

Hydrants are flushed for several reasons:

  • Even the best water can get stale if not used enough and by flushing the City maintains a fresh water supply
  • To help maintain the water quality in the mainlines by removing fine sediment that comes from our water supply and may have settled
  • Flushing will also help the City to use less chlorine but still maintain small amounts in the water system as required by State and EPA regulations
  • To make sure the hydrants are in proper working condition for fire protection

Your water is safe to drink. Fire hydrant flushing is preventative maintenance. There may be a temporary drop in water pressure during testing periods. Occasionally, water becomes discolored after hydrant flushing. City personnel will do everything in their power to keep these conditions to a minimum.  If you notice discolored water, run your cold water tap for a few minutes until the water clears. If it does not clear the first time, wait a few minutes and run the water again. If the water has not cleared after several hours, call the Utilities Division at 279-6164. You should avoid washing clothes until the water clears.
