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.

Note that there has been a significant increase in gross floor area of building space because of the current Transformation Programs at UTAS. The University is well-advanced on a major transformation that involves the relocation of Tasmanian campuses to the three major regional cities as well as major building upgrades to our Sydney campus. The transformation involves an increase in construction and acquisition of buildings, while maintaining former buildings until the programs are completed.

Area of vegetated grounds was estimated using GIS and provided by the University's Contracted Services Administrator (Grounds and Maintenance).
