Complex Water Leak and Pipe Replacement on Mandible Street, Alexandria
Our plumbers were called to a major water leak beneath Mandible Street in Alexandria. There was water all over the centre of the road and Sydney Water had advised us that it was likely coming from a fire service pipe. Since these pipes are used only for firefighting and rarely inspected, they tend to corrode over time, leading to underground failures and leaks with little to no warning.
As Mandile Street is a busy road and is a mix of residential and commercial areas, the local council required us to complete all work at night to manage safety and traffic flow.
What Our Plumbers Found
Once our plumbers shut down the water supply and exposed the leaking pipe using their non-destructive digging techniques, they discovered that the pipe was severely corroded. The corrosion was so severe that repairs would be impractical, so a full replacement was needed.
Our plumbers got to work, replacing 25 metres of steel pipe from the connection point on the opposite side of the road to the building. We also upsized the copper pipe to allow for a higher rate of water flow in the future as the area grows.
How the Work Was Completed
Works were carried out over multiple nights and included:
- Saw cutting and excavation
- Removing the damaged pipe
- Installing new copper pipework
- Installing hydrants and backflow devices
- Backfilling and restoring the roadway
