Optional Fields

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

Water conservation poster developed and displayed regularly in several locations per campus

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

Several rainwater tanks across the three Tasmanian campuses.
The Australian Maritime College cavitation tunnel tanks are use for demineralisation and storage of water for reuse in the cavitation tunnel experiments

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

UTAS has water efficiency infrastructure currently in place across its three campuses, such as dual-flush toilets and low flush urinals in many buildings (not yet across the board) and has been installing water efficient fittings in all new buildings since 2009. Over the coming years, it is envisaged that water efficiency will continue to improve through infrastructure upgrades and behaviour change initiatives

Data source(s) and notes about the submission:

Reticulated water and water from rivers data comes from invoices and submeters. Rainwater data was estimated based on water tanks capacity.
Area of vegetated grounds was estimated based on percentage of forest and planted vegetation areas calculated for GreenMetric in 2016, and applied to total areas in 2015 and 2018. From Google maps, and SISfm landscape and lawn layers. Includes sport fields and farms; excludes water absorption (non vegetated) areas
