When critical underground infrastructure begins to fail, the impact can be far-reaching—especially in high-traffic or environmentally sensitive areas. In early 2025, SA Water faced a challenge in Myponga where a damaged 150mm earthenware sewer main was causing ongoing maintenance issues due to root intrusion and water infiltration. To avoid future disruption and ensure the longevity of the asset, a long-term, minimally invasive solution was needed. That’s where Plumbing & Pipeline Solutions stepped in.
SA Water identified significant root intrusion and water infiltration affecting a 150mm earthenware sewer main in Myponga. The section of main was located adjacent to Main South Road—a high-traffic thoroughfare—making the issue more complex. With ongoing disruptions and the potential for long-term failure, SA Water needed a durable solution that would eliminate the root infiltration issue while causing minimal disruption to traffic and local residents.
Plumbing & Pipeline Solutions (PPS) proposed a Cured-In-Place Pipe (CIPP) lining solution—an advanced, trenchless technology that creates a seamless, jointless liner within the existing pipe. This method completely seals the pipe bore, preventing future root ingress and eliminating weak points caused by traditional joins or cracks.
The CIPP method was chosen for its longevity, cost-efficiency, and minimal surface disruption, making it ideal for high-traffic and environmentally sensitive areas.
PPS delivered the sewer main repair with minimal impact to surrounding residents and traffic flow, completing the project efficiently and on time. The new CIPP liner is expected to extend the service life of the sewer main by up to 50 years, providing SA Water with a long-term, low-maintenance solution that meets their infrastructure and operational standards.
Think long-term infrastructure resilience. Think PPS.
