Upgrading ageing water mains: When is it time to act?
Ageing water infrastructure can lead to leaks, service interruptions and rising maintenance costs. Learn the common warning signs and how timely renewal programs protect network reliability.
Read the Article
Much of South East Queensland’s water network was laid decades ago, and the region’s growth is asking more of those pipes every year. Knowing when to renew a water main, rather than continue repairing it, is one of the most valuable judgements an asset owner can make.
The warning signs
Rising break frequency is the clearest signal. A main that once failed every few years and now fails every few months is telling you something. Other indicators include declining water quality from internal corrosion, pressure complaints, visible corrosion on exposed sections and repair costs that begin to rival renewal costs.
Repair, reline or replace
Not every ageing main needs open trench replacement. Slip lining and pipeline relining can rehabilitate a structurally sound host pipe at lower cost and with minimal excavation. Trenchless methods like horizontal directional drilling allow new mains to be installed beneath roads, creeks and sensitive areas without surface disruption. The right answer depends on condition, criticality and constraints, which is why condition assessment should come first.
Keeping customers in water during renewal
The best renewal programs are the ones customers barely notice. Live connection techniques such as under pressure tapping and line stopping allow new mains to be tied in without shutting down the network. Temporary bypass systems maintain supply during construction, and careful shutdown planning keeps any interruptions short and well communicated.
