Harpers Hill Reservoir and Lochinvar trunk main upgrade
We are replacing the ageing water reservoir at Harpers Hill with a higher volume structure to provide a more reliable water service for the area’s growing population.
We are also building an additional pipeline to transfer more water to the new reservoir.
This project is part Hunter Water’s program to improve the reliability of our system by upgrading ageing assets.
Project benefits
Once the reservoir has been built and connected to the completed pipeline, customers will experience improved water pressure and a more reliable water supply at times of peak demand.
Additionally, the new reservoir and pipeline will provide a reliable and adequate water supply for residential and commercial growth in the area for at least the next 15 to 20 years.
