Smarter water use helping University save water

As part of its broader sustainability strategy, the University has implemented a range of water-saving initiatives across its campuses.

These initiatives include large-scale on-site tanks and stormwater retention dams that prioritise the use of captured rainwater for irrigation. The systems are designed to automatically draw from stored rainwater, switching to potable water only when necessary, dramatically reducing reliance on drinking water for outdoor use.

Currently, the University captures and stores approximately 2.7 million litres of water in rainwater tanks. The water is used to irrigate its sporting fields across the Callaghan campus, with its Oval 3 irrigated almost entirely with harvested rainwater.

The University is also rolling out Hunter Hydrawise smart irrigation controllers across its sporting fields. These advanced systems offer live weather integration and leak detection.

By avoiding unnecessary watering, these smart irrigation systems are expected to save up to 50,000 litres of water*, contributing significantly to the University’s conservation efforts.

These upgrades are part of a broader commitment to sustainable campus operations and delivering better environmental outcomes for the University and wider community.

This initiative supports United Nations Sustainable Development Goal (SDG) 6: Clean Water and Sanitation - by promoting efficient and sustainable water management on campus.
