Installing a pool or spa

Diving into a pool installation project? Find out what you need to get going.

Our main concern when you are installing a pool or spa is to check that it is not located too close to our water, wastewater or drainage services.

In most cases, water mains and drainage mains will not be located inside your property, but our sewer mains may be. 

We ask that you complete a self-assessment of the location and depth of the proposed pool or spa against our existing sewer mains. If you plan to build it too close, you may need to revise your plans.

Make sure your pool is waterwise!

Submitting your application

You need to submit a minor plan application when you are installing a pool on your property.

Step 1: Self-assessment

Before submitting your application online, we recommend you complete a self-assessment of your application by following these steps:

  1. Obtain plans from Dial Before You Dig.
  2. Determine the location of the sewer main.
  3. Determine the material and depth of the sewer main.
  4. Refer to the Residential guidelines for designers document for the appropriate protection of sewer main information.
  5. Self-assess your design with our requirements.

In some cases you may need to relocate your internal plumbing or sewer lines and you will need to contact a licensed plumber to carry this out.
