Description: As part of Public Drinking Water Source Areas (PDWSA) and in addition to priority classification areas, wellhead protection zones (WHPZ) and reservoir protection zones (RPZ) are defined to protect the drinking water source from contamination in the immediate vicinity of production wells and reservoirs. Statutes under the Country Areas Water Supply Act, 1947 (CAWS Act), the Metropolitan Drinking Water Supply, Sewerage and Drainage Act, 1909 (MWSSD Act) and the Planning and Development Act (2005) provide for defined land uses and activities within these zones that are prohibited, restricted or subject to agency conditions so that contamination of the water source is prevented. Special conditions, such as restrictions on storage and use of chemicals, may be applied within these zones. WHPZ are usually circular, with a radius of 500 metres in P1 areas and 300 metres in P2 and P3 areas. WHPZ do not extend outside PDWSA boundaries. RPZ consist of a 2 kilometre buffer area around the top water level of storage reservoirs and include the reservoir itself. A reduced buffer area may be applied where the reservoir is designed only for short-term storage of collected water (eg. pipehead or pumpback dams)before transfer to a main storage reservoir. Reservoir protection zones are normally only designated over Crown land and generally prohibit public access to prevent contamination (physical, chemical and biological) of the source. Reservoir protection zones do not extend outside PDWSA boundaries (eg. down stream of dam wall). New bylaws are currently being developed to allow RPZ and WHPZ to be established using uniform conditions in both country and metropolitan catchment areas.Data update: 14/10/2016
