Water Main Failures in Kew
Kew's established streets are lined with mature trees whose root systems extend well beyond the canopy — and often directly into or alongside underground water mains. Many Kew properties still have original copper or galvanised supply lines running from the meter to the house, some installed 50 or more years ago. Root intrusion, soil movement during Melbourne's wet/dry seasonal cycles, and simple age all contribute to main failures in the area.
A full water main replacement is needed when the existing line has failed at multiple points, has been compromised by root intrusion along its length, or is so corroded internally that repair is not cost-effective. We assess the existing main before recommending replacement versus spot repair — if a single isolated section has failed, a targeted repair is usually the better option.
What This Job Involved
The photo shows the new copper supply line laid in the open trench before backfilling. The pipe runs from the meter at the boundary to the property's entry point — a straight run through the garden that was cleared, trenched, piped, and reinstated in a single day. The pipe is laid at the correct depth for Melbourne conditions and will be fully enclosed by soil once backfilled and compacted.
We called Dial Before You Dig prior to excavation to confirm the location of any other services in the trench path. All copper joints were silver-soldered and pressure-tested before the trench was closed. The garden was reinstated to its original condition on completion.
What's Involved in a Water Main Replacement
- Dial Before You Dig service check to locate underground utilities in the trench path
- Isolation of property water supply at the meter
- Trenching along the new or existing pipe route
- Installation of new copper supply line at correct depth and fall
- Silver-soldered joints throughout, pressure tested before backfill
- Backfill, compact, and reinstate garden or lawn surface
- Notify Yarra Valley Water if connection point at meter was disturbed
