Lismore City Council's Water and Wastewater team has successfully completed the upgrade of about 1732 metres of ageing cast iron water pipes, replacing them with a modern polyethylene, fully welded system.
This project represents a major step forward in enhancing the reliability and sustainability of our city's water infrastructure.
The original cast iron pipes, many of which were over 100 years old, were prioritised for replacement due to age, increased risk of failure and suspected leakage at the joints. By transitioning to the new polyethylene system, Council is ensuring a more dependable and safe water supply for residents and businesses alike.
This upgrade was carried out using horizontal directional drilling, a technique that enabled faster installation, reduced costs and minimised disruptions to the community compared with traditional open-cut excavation methods.
All pressure tests were solid and independently verified by NATA-accredited third-party assessors, with bacterial and chemical testing confirming full compliance with Australian drinking water guidelines.
The completion of this project reaffirms Council's commitment to providing essential services efficiently and responsibly. This critical upgrade ensures the city's infrastructure remains robust and well-maintained, securing a reliable water supply for both current and future generations.
