Estimated water supply

The objectives of the current study are to develop a methodology to estimate the optimal size of the rainwater tank at a particular location considering the local rainfall, roof area, demand for water and the reliability of supply (supply security) required; to quantify the rainwater volume that could be harvested at site using domestic rainwater tanks to minimise pressure on the potable water supply secured from traditional catchment sources until the desalination plant is commissioned in 2013; to analyse the efficacy of rainwater tanks to reduce the stormwater runoff and improve the quali...

The earth’s surface is two-thirds water, yet most of this is undrinkable or unusable because it is either seawater or ice. Of the 1% that is available as fresh water, most is used for farming or industry. Fresh water pollution is the major problem because many rivers and streams are being polluted with pesticides, industrial waste, and sewage. In poor and developing countries, the addition of sewage to the sources of water leads to diseases, and even death. A United Nations’ report estimates that more than 78% of people drink from polluted water supplies.
