Ground temperature and water temperature can contribute
to water main breaks. Prolonged periods of below zero
temperatures can cause the soil to freeze quite deep
into the ground. This freezing can cause
expansion and contraction that creates force on the
Pressure Changes in the System
Changes in pressure can cause main breaks. This usually
occurs at points where there is a pre-existing weakness
in the pipe. Overall system demands (such as very hot,
dry days with high water use) can also cause changes in
pressure that lead to main breaks.
What is involved in repairing a water main?
When a call or customer request is received, our crew is dispatched to determine the location, impact and severity of the break. First the water main is "controlled", by closing nearby valves that control the mains. Depending on the type of leak, this will either reduce the flow of water to the affected water main or shut it off completely.
Once the general repair location has been identified and the water main is shut off, special equipment is used to find the precise location of the leak. Then, our plumbers are dispatched to the location to begin the repairs.
Once the problematic water main and the repair is completed. The pipes are then flushed and water is tested to ensure water quality before water service is restored.
After that, the damaged road, lane, sidewalk or lawn must be repaired to the match the existing surface features. This may take some time depending on the construction season, weather and the availability of equipment and materials.
