Promoting Conscious Water Usage on Campus

The University of Newcastle actively promotes conscious water usage across campuses. In 2025, the University communicated practical ways of conserving water on campus, while equipping its facilities and grounds teams with information to identify waste and make water-conscious operational decisions. This approach connects awareness of water conservation with visible action in the places where water is used.

Making water conservation visible

The Environmental Sustainability Policy operating in 2025 commits the University to actively promoting environmental sustainability initiatives to staff and students and building awareness and behaviour change. Its water provisions prioritise reducing mains water use, reusing water and considering water efficiency in campus development.

In its July 2025 article, “Smarter water use helping University save water”, the University explained to its community how rainwater harvesting, more efficient irrigation and monitoring reduce unnecessary demand for potable water. It also communicated a target to reduce mains water consumption per square metre by 15% by the end of 2025, compared with a 2015 baseline. Communicating both the purpose of these measures and how they work helps make water-conscious choices part of everyday campus operations.

Using water data to guide campus decisions

In 2024, the University worked with Hunter Water on a campus water-use audit and installed real-time water monitoring across its campuses. Meters and alerts inform facilities staff when consumption is unusually high or a possible leak is detected, allowing teams to investigate promptly. The audit identified previously undetected leaks and inefficiencies, and remediation work followed. This monitoring gives staff practical feedback about how water is used and where it can be saved.

These operational measures complement ongoing reporting and the University’s approach to incorporating water efficiency into building management, maintenance and landscape decisions.

Showing what water-conscious irrigation looks like

In 2025, the University described approximately 2.7 million litres of rainwater tank storage capacity used to reduce demand for mains water on the Callaghan sporting fields. Oval 3 is irrigated almost entirely with harvested rainwater. The irrigation systems draw from stored rainwater first and switch to mains supply only when necessary.

The University was also rolling out Hunter Hydrawise smart irrigation controllers across its sporting fields during 2025. These systems use weather information and leak alerts to avoid unnecessary irrigation. The University estimated that cancelling a watering cycle because of rain or wind in the forecast could save up to 50,000 litres of water for that cycle, rather than 50,000 litres as a confirmed annual total.

Monitoring annual water use

The original University water-management material includes the following annual potable-water-use chart for 2021–2025. Tracking annual consumption alongside operational monitoring helps identify changing patterns of use and guides further opportunities to conserve water.
