Smoke testing program

We are continuously working to improve the quality and reliability of our wastewater system. Inspections and maintenance are undertaken on an ongoing basis to help ensure a high quality service to customers.

When is smoke testing used?

Smoke testing may be used for routine maintenance, to investigate reported odours, and to identify where stormwater is entering the sewer system. We also use smoke testing to check if there are illegal stormwater connections on residential or business premises.

How we undertake smoke testing

We use smoke to test our above and below ground pipes and equipment. You may notice smoke rising from our structures in the street or in reserves near your home.

  • Smoke from our assets - Smoke escaping from our pipes, pumping stations, hatches and other structures helps identify where we need to make repairs to our system.
  • Smoke at a customer's property - Smoke escaping from drainage grates and gutters on a customer's property, or inside their home through drains in the kitchen, bathroom or laundry, may indicate the customer needs to make repairs to their plumbing.

If we are testing for stormwater connections in your street you will receive information about the project before work begins near your home.

We will have employees or contractors on site to undertake the testing. You do not need to take any action or report the smoke. The smoke does not indicate a fire.
