Find out about water source protection areas in the City of Stirling. These areas are defined to manage the risk of pollution of the water source where these sources co-exist with other land uses.

Drinking water sourced from aquifers is protected by the declaration of Underground Water Pollution Control Areas (UWPCAs) as a provision of the Metropolitan Water Supply, Sewerage and Drainage Act 1909.

Priority 3 source protection areas are defined to manage the risk of pollution of the water source and are declared over land where water supply sources need to co-exist with other land uses such as residential, commercial and light industrial developments, although there is some restriction on potentially highly polluting land uses.

The Department of Environment and Regulation has published a Water Quality Protection Note, which discusses the compatibility of land uses within the different priority source protection areas. The guidelines lists land uses which are compatible, incompatible, and conditional with or in regard to the management objectives of the priority source protection areas. Land uses and developments in all priority source protection areas that have the potential to impact detrimentally on the quality and quantity of public drinking water supplies should not be permitted unless it can be demonstrated, having regard to advice from the Department of Environment and Conservation, that such impacts can be satisfactorily managed.
