Description: The Public Drinking Water Source Area (PDWSA) dataset is currently used by the Department of Environment and Conservation and the Department of Water in policy decision making and for providing advice.These areas require protection to maintain the quality of raw water used to supply public drinking water schemes. The quality of declared water sources in Western Australia is protected by declaring PDWSA under the Country Areas Water Supply Act, 1947 (CAWS Act)and the Metropolitan Water Supply Sewerage and Drainage Act, 1909, (MWSSD Act). By-laws under both the CAWS Act and the MWSSD Act enable the Department of Environment to control potential polluting activities, to regulate landuse, inspect premises and take necessary steps to prevent or ameliorate pollution.PRIORITY CLASSIFIED AREAS Land use regulation and control is achieved through the classification of land into one of three management categories referred to as 'priority classification areas' Priority 1 (P1) classification areas are defined to ensure that there is no degradation of the water source. P1 areas are declared over land where the provision pf the highest quality public drinking water is the prime beneficial land use. P1 areas would typically include land under Public ownership. P1 areas are managed in accordance with the principal of risk avoidance and so land development is generally not permitted. Priority 2 (P2) classification areas are defined to ensure that there is no increased risk of pollution to the water source. P2 areas are declared over land where low intensity development (such as rural) already exists. Protection of public water supply sources is a high priority in these areas. P2 areas are managed in accordance with the principle of risk minimisation and so some development is allowed under specific guidelines. Priority 3 (P3) classification areas are defined to manage the risk of pollution to the water source. P3 areas are declared over land where water supply sources need to co-exist with other land uses such as residential, commercial and light industrial developments. Protection of P3 areas is achieved through management guidelines rather than restrictions on land use. If the water source does become contaminated, then water may need to be treated or an alternative water source found.Data updated: August 2018
