Water System Flushing Program - FAQ

What if flushing?

Answer: Flushing is the opening of a fire hydrant/blow-off valve allowing water to discharge at a higher velocity than normal from main lines and dead-end lines.

Why is flushing important?

Answer: Flushing enhances water quality and system operation by:

  • Flushing sediment from distribution lines;
  • Checking for weak flows in distribution lines;
  • Verifying proper operation of hydrants and valves; and
  • Ensuring firefighting capability.

When does flushing occur?

Answer: Flushing activities are scheduled annually typically during winter/spring months.  The flushing season can be extended depending on the water year.

Can I find out where flushing is occurring?

Answer: Call the main office to determine if flushing is occurring in your area.

What should I do when I see the District crew flushing in my area?

Answer: If you see District staff flushing please drive carefully and treat them like any other road construction crew.

How will my water supply be affected?

Answer: There may be a slight drop in pressure or noticeable discoloration of your water from the minerals and sediments that are being flushed out.  Water service should not be disrupted during the flushing process.  If discoloration is observed, operate outside spiget or cold water tap for a few minutes or until water clears.

What about water pressure and safety?

Answer: Flushing may cause short-term pressure fluctuation along with sediments in your water.  Try not to use water during this time.  However, your water remains safe, meeting or exceeding all water quality standards.

Is flushing a waste of water?

Answer: This is a normal and necessary part of maintaining a safe and reliable drinking water supply for District customers.

Do other water suppliers have a similar program?

Answer: Many water suppliers have some type of flushing program to clean their water pipes to ensure clean and reliable drinking water for their customers.
