Proclaiming public drinking water source areas
Western Australia's drinking water comes from both surface water andgroundwater sources.
The state proclaims public drinking water source areas under the Metropolitan Water Supply, Sewerage and Drainage Act 1909 or the Country Areas Water Supply Act 1947 as waterreserves, catchment areas or underground water pollution control areas.
These acts provide the powers necessary to legally define the boundaryof public drinking water source areas and also provide by-laws which are usedto help protect water quality of these sources and public health. Please note the Department of Water is running a consultation process with stakeholders to review the drafting instructionsfor the public drinking water source area by-laws, which propose to amend orrepeal the existing by-laws under both of these acts.
Water quality protection note no. 75: Gazetted public drinking water source areas provides alist of currently proclaimed public drinking water source areas in WesternAustralia, or you can find them in the Geographic Data Atlas.
