Purpose

The purpose of the flushing program is to provide better water quality to our customers.

Flushing water mains removes sediment that may have accumulated in the water main pipes. The City of Aurora has used computer modeling of the water system to develop a program that combines unidirectional and conventional flushing methods.

Unidirectional water main flushing uses a systematic method of closing water main valves and opening hydrants to direct water through targeted segments of pipe at a high water flow velocity. This method uses less water and is more effective at removing sediments than conventional flushing procedures, but can take more time and be more costly.

Conventional water main flushing uses a sequential method of opening each hydrant along a section of water main without closing water main valves. This method can be completed more quickly than unidirectional flushing but may use more water and is less effective on larger size pipes.

The water main flushing program accomplishes different goals than the yearly fire hydrant flow testing performed by the Aurora Fire Department.

The following should help minimize problems:

  • Watch for signs placed a few days before flushing occurs in your area.

  • If water discoloration is noticed, stop all water use and wait, several hours may be required to rid the cloudiness from the water mains that serve your home or business.

  • Turn on outside spigots, cold water bathtub faucets, flush toilets, and run a cycle through the washing machine to clear the water in your service line.

  • Be certain discolored water is out of your water service line before using large amounts of water or doing laundry.

  • Do not wash clothes or run a dishwasher during or immediately after flushing takes place. Washing clothes with discolored water can cause laundry stains.

  • If laundry does become stained, do not dry it; request a free bottle of liquid polymer laundry aide (poly) from the City of Aurora Water Production Division at (630) 256-3250 which may remove the stains.

  • Discolored water poses no threat to your health. You may wish to avoid drinking or cooking with the water.
