Sewer chokes

A sewer choke is a blockage in a wastewater pipe. They occur when there's something inside the pipe that stops it working properly. 

Sewer chokes are usually caused:

  • by tree roots that have found a way into the pipes
  • when someone puts something down the toilet that it's not designed for. For example, children sometimes put soft toys down the toilet.

If you have a sewer choke in the private wastewater pipes on your property, call a licensed plumber.

If you think the sewer choke is in our pipes, call us on 13 20 90. We'll ask you some questions, so we can work out:

  • what's causing the problem
  • where the problem is.


If we think the problem is in our pipes, we'll send someone out to have a look. We should be there within three hours. If the problem is in our wastewater system, we'll fix it. 

If we think the problem is in your pipes, we'll advise you to hire a licensed plumber to investigate the problem.

You can find out where our pipes are by buying a Service Location Diagram. You can also find out where your pipes are by buying a Sewerage Service Diagram. 

You can buy these diagrams at Sydney Water Tap in™ or through one of our Property Link brokers

If your licensed plumber finds that your private wastewater pipes are collapsed under a public road or public footpath and we verify that the collapse can’t be repaired without excavating, we'd like to help.

From 1 July 2015, we may offer to repair the collapsed section of pipe at our cost if you meet the criteria (conditions apply). 

We can't reimburse you or your plumber for any plumbing costs related to this work.
