Drinking water quality standards describes the quality parameters set for drinking water. Water may contain many harmful constituents, yet there are no universally recognized and accepted international standards for drinking water. Even where standards do exist, the permitted concentration of individual constituents may vary by as much as ten ...
An adequate supply of fresh drinking water and the proper disposal of sewage was an early priority in Melbourne. In 1853, a Commission of Sewers and Water Supply was established to improve the provision of each. [15] The Yarra River above the falls was the main source of drinking water till the completion of the Yan Yean Reservoir. Construction ...
The addition of fluoride to a drinking water supply is generally governed by the Australian Drinking Water Guidelines. [6] The Guidelines recommend a health-related guideline value (maximum concentration) of 1.5 mg/L for fluoride, which mirrors the World Health Organization Guidelines for Drinking Water Quality 2006.

The Water Efficiency Labelling and Standard (WELS) scheme is an Australian Government urban water conservation program. [1] Its aim is to reduce demand for drinking water by informing consumers about water efficiency at the point of sale.
Australia now provides fluoridated water for 70% or more of the population in all states and territories. Many of Australia's drinking water supplies began fluoridation in the 1960s and 1970s. By 1984 almost 66% of the Australian population had access to fluoridated drinking water, represented by 850 towns and cities.
Sources where drinking water is commonly obtained include springs, hyporheic zones and aquifers (groundwater), from rainwater harvesting, surface water (from rivers, streams, glaciers), or desalinated seawater. For these water sources to be consumed safely, they must receive adequate water treatment and meet drinking water quality standards. [5]
The Sydney Desalination Plant is to be turned on when Sydney's drinking water level reaches 60% capacity, and water restrictions will be in place when drinking water reaches 50% capacity. [18] Sydney Water has imposed fines of $220 for violations [6] of the rules for individuals, $550 [6] for businesses, and $2,200 for water theft. [19]
The most common standards used to monitor and assess water quality convey the health of ecosystems, safety of human contact, extent of water pollution and condition of drinking water. Water quality has a significant impact on water supply and often determines supply options.
