Defence used over 9.2 gigalitres in 2005: had identified 45 high-water-use sites; plans use of rainwater, stormwater, recycling

Brendan Nelson, Member for Bradfield, and Minister for Defence, Australia Liberal Party, speaking to the Commonwealth House of Representatives on 20 September 2007, said Defence water usage was monitored locally at Defence sites. Data was not aggregated nationally. Water usage across the whole of Defence was in the order of 9.2 gigalitres in 2005 (based on a water use and consumption profile study of Defence facilities).

Water conservation plans: Defence plans were described in its ;

• Environmental Management System;

• site environmental management plans; and the

• Defence Sustainable Water Management Strategy.

The objectives of the strategy were to:

• maximise efficiency of water use;

• eliminate losses through leakage and waste; and

• reduce potable water-use, by substituting lower grade sources of water where they remain fit for purpose (for example the collection and use of rainwater and stormwater, recycling of grey water and waste water).

The grand plan, for 45 sites: Defence had;

• identified 45 high-water-use sites across the Defence estate;

• looked for opportunities at these sites for reducing potable water consumption and increasing the use of rainwater and stormwater, and the recycling of grey water and waste water;

• set a 30 per cent water saving target in potable water in new buildings and major refurbishments;

• specified water efficient fittings, fixtures and appliances which had a minimum AAA rating or equivalent water efficiency labelling and standards scheme star rating; and

• developed regional and site water management plans for the Defence Estate.

Examples of water efficiency projects: Examples of water efficiency projects implemented across the Defence Estate included:

• waste water recycling for irrigation of the sports ground at the Royal Military College Duntroon and the Australian Defence Force Academy;

• recycled water washpoint facilities at Gallipoli Barracks and Lavarack Barracks;

• rainwater harvesting for HMAS Cairns redevelopment and Oakey Army Aviation Centre;

• waterless urinals at RAAF Richmond and Enoggera Army Barracks; and the

• dual flush toilets in various facilities.
