The City’s annual watermain flushing program began February 19, 2024 and ran for 12 weeks. All residents and businesses in the following areas (shown in the map) were part of the watermain flushing zone:
- South of Lougheed Hwy to the southern edge of the City (Argue Street)
- West of Broadway Street to the western edge of the City (Westwood Street)
What is flushing?
Flushing is a process that rapidly moves water through the piping system using water velocity to scour out materials that accumulate in the City’s pipes.Flushing is an important part of the City’s ongoing maintenance program to ensure the integrity of the water supply system. The City of Port Coquitlam flushes one third of the City’s watermains each year in order to minimize sediment deposits in the City’s water system that can deteriorate water quality.
Flushing generally takes place between the hours of 7am and 5pm, Monday through Friday (some exceptions may apply). During these times, residents and businesses can expect some discolouration of water and intermittent drops in water pressure. While some discolouration or sediment in the water may occur, it is a temporary condition and is not a health concern.
Steps To Take After Flushing
Please follow these guidelines during the watermain flushing program to clear your water:
- You can clear the water by running an indoor cold water tap for 20-30 minutes after the flushing period
- Avoid doing laundry while your water is discoloured
- Avoid using your hot water if the water is discoloured to prevent sediment from entering into your water tank
- Please note that water can take up to two hours to clear.
