What is Watermain Flushing?
Watermain flushing is the process of cleaning and clearing newly installed, repaired, or existing watermains by moving water through the pipe at a controlled velocity. This helps remove sediment, debris, construction materials, stagnant water, and other unwanted materials before the watermain is placed into service.
Watermain flushing is commonly required for:
- New watermain installation
- Watermain repairs and tie-ins
- Subdivision and municipal infrastructure projects
- Fire hydrant and distribution system flushing
- Pre-disinfection and post-disinfection flushing
- Water quality improvement programs
- Commissioning and close-out documentation
