Development Applications

Development Applications

The following key steps outline the process of submitting a development application (DA) in the Sydney drinking water catchment where all proposed developments need to have a neutral or beneficial effect (NorBE) on water quality.

If you have any questions about the process or your development application, you should contact your local council directly.

Steps to submit a DA

1. Contact your local council to discuss your proposal / development

Tip: To find out if your development is in the drinking water catchment, refer to the interactive catchment map.

2. Prepare your development application (DA)

Your DA must include a water cycle management study or equivalent information - this includes details on how your DA will deal with wastewater, stormwater, erosion and sediment control, and other information that will help to assess your DA.

The study must include a statement as to whether the development would have a NorBE. Your DA should also incorporate WaterNSW endorsed management practices or alternative management practices or standards to achieve outcomes not less than those achieved by Water NSW’s current recommended practices and standards.

Tips:

  1.
