Water Main Flushing Program

Water Main Flushing Program

This program is one of our most effective maintenance and water quality tools we use to provide safe, clean water to our customers. The City's Utility crews perform flushing activates during warm weather months, May to September. Cold weather effectively stops this program since icing can produce hazardous conditions.

Why do water mains need to be flushed?

The slow moving water in the water mains allows minerals and sediments to deposit and accumulate over time. These deposits can result in water color and water quality problems.

Flushing is a process by which water is moved through a water main at a high velocity so that a scouring action is created. The water is then discharged through a fire hydrant. The goal of this program is to ensure that water quality is maintained at its optimal level and to help with the proper maintenance of the City's water distribution lines. Flushing also enhances fire protection by ensuring that fire hydrants are in working order throughout the area we serve.

How will flushing affect my service?

Water service will not be interrupted when the pipes are flushed. Occasionally, after flushing work is done in your area, you may need to run your taps for a couple of minutes until the water is clear. If this does happen, we recommend that you run your front yard faucet first to clear any remaining sediment out of the service line to the house. Your water may appear dirty for a short period of time, but this is a temporary condition and not a health risk.

We want to assure our customers that any effect will be temporary. If there is a discoloration of your water that does not clear up quickly, please call the Water Division at 720-898-7760 (8 am to 5 pm, Monday to Friday) or 720-898-7820 after hours.
