Cutting down on water

We know we use a lot of water, and we are setting tough targets to reduce our water use.
 
As part of Alcoa’s Water Conservation Strategy in Australia, we are focused on reducing our overall consumption of water, increasing water use efficiency and replacing high grade water sources, which are used by the broader community, with lower grade sources.
 
In 2007 Alcoa announced its support of a comprehensive study into rural water usage which aims to reshape water saving attitudes.  The innovative research study is a partnership between Wannon Water, Deakin University, the Alcoa Foundation, Portland Aluminium and the Victorian Government ‘SmartWater!’ Fund.
 
It will identify water usage behaviours in regional and rural settings and be an invaluable tool for water authorities in Victoria and Australia-wide in developing sustainable water use strategies.

The $US55000 Alcoa Foundation grant is vital support for sustainable water conservation activities in the Wannon Water region.
 
While the Wannon water region hasn’t had the same level of water scarcity that other regions in Australia have suffered, it will help to understand Australian attitudes to water in good times as well as bad.
 
The research will include in-depth interviews and surveys with both rural and regional water uses, culminating in the development and evaluation of a behaviour change strategy pilot program.
Our West Australian mining operations have also been successful, reducing total water use by 22 per cent since 2000 while also increasing waste water recycling and storm water capture.
 
In 2007 our McCoy Crusher Facility at the Huntly bauxite mine in Western Australia was awarded the Water Recycling Award by the Department of Water and the Water Corporation.
 
The McCoy facility was specifically designed to maximize water harvesting and recycling.
 
Storm water runoff and treated wastewater are collected in a purpose built reservoir and used for haul road dust suppression.  This leading edge design was created from a range of industry best practice engineering solutions and successful innovations.
 
Alcoa's Pinjarra refinery has for the last three years, taken the tertiary treated sewage effluent from the sewage treatment plant at that township. This 241ML of water annually allows the refinery to lessen the use of fresh water sources, while at the same time lessening the nutrient-rich input that would otherwise have made its way into the Peel-Harvey estuary system.
 
As one of Australia’s leading integrated resource producers and exporters, Alcoa is sharing its wealth of knowledge about sustainability with industry and the community with the introduction of a new online initiative – Our Sustainability Story.
 
Our Sustainability Story can be found at www.alcoa.com.au/sustainability.  It focuses on Alcoa’s performance in 2007 and provides direct transparent access to detailed information on how the company is leading, managing, responding and planning for the sustainability of the business.
