A brief description of the institution's water-related behavior change initiatives:

UQ’s Water Management Program was implemented almost 2 decades ago, and was devised to ensure the efficient use of water resources across all University sites and campuses, increase the use of alternative water supplies and raise staff and student awareness about the importance of sustainable water management.

The Sustainability Office is responsible for the delivery of awareness programs through a number of initiatives. Online Sustainability General Training and Sustainability Laboratory Training modules havebeen developed for new staff to complete as part of the induction process. The Green Office and Green Lab Representative training also includes a section focused on water conservation.

A brief description of the institution's water recovery and reuse initiatives:

Measures include retrofitting kitchens with water-efficient taps and bathrooms with water-efficient toilets, showers and taps to reduce water consumption, installing water-monitoring systems across campuses, incorporating water conservation design and management principles in the University’s Landscape Management Plan, maximising the use of recycled water and undertaking water-efficiency audits.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

Water infrastructure, meters and fixtures are continually being audited to ensure optimal water efficiency, including checking leak prevention measures, installation of low flow devices, and the rolling out of the Automatic Metering Reading system.

On campus irrigation uses recycled water and dam water. This contributes to the difference between total water use and potable water use.
