Current recommended practices and performance standards

Best practices endorsed by WaterNSW are referred to as current recommended practices (CRPs) and performance standards.

The aim of CRPs and standards is to provide best practice solutions to manage the water quality impacts from a range of land uses, developments and activities including rural subdivisions, agriculture, industrial developments, and stormwater and wastewater management. The State Environmental Planning Policy (Sydney Drinking Water Catchment) 2011 (SEPP) requires all proposed development in the Sydney drinking water catchment to have a neutral or beneficial effect on water quality (NorBE). Therefore, to achieve compliance with the Sydney Drinking Water SEPP, CRPs and standards are to be used by developers and consultants to design and prepare proposals for new development in the Sydney drinking water catchment. They are not intended for ongoing land management or existing land use management.

Note: Developers and consultants must demonstrate compliance with CRPs and standards in their applications. Where different management practices are incorporated (outside of CRPs), it must be demonstrated that these practices achieve an equivalent or better outcome for water quality in the Sydney Drinking Water Catchment.

For some land uses, such as stormwater management and roads, more than one CRP document has been endorsed as the documents focus on different aspects of the development and approval process. This ensures the best coverage of the subject and allows some flexibility to adopt the most appropriate practices for the specific circumstances of each development and site. It should be noted that CRPs published by WaterNSW may include specific requirements (for instance minimum buffer distances to watercourses) that prevail over other CRPs or standards.

The list of CRPs and standards will change as more CRPs are endorsed and updated, or management practices and technology change.

*Guidelines that do not fully meet the endorsement criteria but nevertheless contain useful information or pertain to a less common land use in the catchment are listed here as an Additional Reference.
