A brief description of the institution's water-related behavior change initiatives:
In 2019 the University signed up to the Irish Water Stewardship Program and underwent a water mapping program to determine the significant users of water across the estate. From the mapping exercise a water charter was developed to implement a number of water conservation measures across the Estate. Measures included the fitting of water meters to actively monitor the esates consumption and identify any underground leaks, installation of low flow and flushing devices as well as the installation of auto shut off systems to shut down water supplies when the buildings are closed.

A brief description of the institution's water recovery and reuse initiatives:
The existing drinking fountains across the University were upgraded to auto bottle filling units to minimise the water waste. Signage installed in toilets and labs to turn off taps and report leaks to the B&E office to conserve water use.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
The water flows from taps were checked and reduced where possible and resulted in significant savings. Automatic presence sensors were installed in the Boole Library to eliminate the requirement for a time flushing.
