Coronavirus update 13 March 2020

COVID-19 restrictions: what's closed and what's open.


  • You must have approval to discharge stormwater into Council's drain system.
  • Allow at least 10 weeks to complete the approval process.
  • Up to 3 fees may apply.
  • Sewage or groundwater are not discharged into our drain system.

Follow these steps to connect your private property to Council's stormwater drainage system.

To learn about the difference between private and Council drainage, see Drains and stormwater.

Step 1: Apply for an approved point of discharge

To apply for an approved point of discharge, download and complete the Application and payment form.

With your application, you'll need to include:

  • information on your site's location
  • floor plans
  • Planning Permit(s) if applicable for the work you are doing. Check Do I need a permit if you are not sure.
  • $144.70 application fee.

Applications take 10 working days to process.

Once your application is approved, we'll send you a certificate showing the point of discharge you're allowed to use.

You only need to continue to steps 2 and 3 if your development needs on-site detention or external draining works. This will be detailed on the certificate we send you.

Step 2: Apply for an Onsite Detention System Assessment

Refer to the Standard Drawings for design and connection requirements:

The approved point of discharge advice should contain drainage connection requirements for your site. For clarification of this advice please contact the Drainage Team on 9278 4444 or email us.

If Council has advised that onsite stormwater detention and/or outfall drainage is required, engineering drawings must be prepared and submitted to Council along with an application for Onsite Detention System Assessment.

With your application, you'll need to include:

  • a completed OSD design checklist
  • drainage design drawings (hardcopy A1 drawings may be requested later)
  • drainage computations
  • hydraulic grade line
  • copy of the current property title.
  • fee for assessment of your plans: $138 (1-3 units); $276 (4-10 units); $552 (11+ units)
  • $143 fee for a drain inspection.

Applications take 4 to 6 weeks to process.

To request a stormwater connection within a road reserve, you'll also need a Works within a Road Reserve Permit.

Step 3: Book a stormwater drain inspection

Once your stormwater drainage connection has been approved, you can then book a drain inspection.

Book a drain inspection

When you book, you'll be asked to provide:

  • a Council-approved letter
  • photos of the orifice plate (for controlling water flow) and trash grate (for filtering stormwater).

We'll contact you to arrange an inspection time within 5 working days.
