It was finally admitted that demand was driven by mining and urban expansion, and would lead to a fresh water shortage, as WA contended with rainfall levels that have been dropping since the 1950's. The strategic planning manager commented that the annual water use has climbed more than half a trillion litres this century, in 2007-08 total state water use was 2426 billion litres compared with 1790 billion litres in 1999-2000. Yet we can't forget Water Corp's graphs from 2.1/2 years ago showing our rainfall hadn't altered since 1910, so which set are we to believe!
. So that leaves one asking, how good are the sustainability strategies government carries out each year, it always seems communities are told to cut back. Why is industry given a free reign, how many desalination plants or reclamation plants have they paid for. It was stated that Perth metropolitan area and the Pilbra would possible be hit the hardest by future shortages.
.With a growing population and an expected 15 per cent down turn in rainfall, meant urban areas could face a total annual shortfall of up to 75 billion litres. More mining in the Pilbra was likely to double water demand by 2030, Mr Hauck said it's not surprising we have a collective water crisis. Yet we still have water in dams that government prefer to pump out to sea than run through reverse osmosis and use in the metro dams.
