Many properties in urban areas will have the option to join our sewer network. The primary requirement for a property is that it's fronted by one of our mains.  If you're property isn't currently fronted by a main, you may be eligible to apply to extend our network.

Homes in unsewered areas use a septic tank system that treats the wastewater on site.  Your local council regulates the use of septic tanks in unsewered areas.

Step 2:  Find out if your property is fronted by a main

To find out if your property is fronted by a main, use our interactive map of GWMWater assets or get in touch with us.


Step 3: Find a licensed plumber

Only a licensed plumber can connect you to a main. This is to ensure the safety of our system and the community.  You'll need to find a plumber before applying for permission to connect, as you're required to supply their details on the application form.


Step 4:  Apply to connect

If you're ready to connect to our sewerage services you'll need permission from us before you begin any works.
