Special requirements for boundary traps
A boundary trap is a pipe that runs from your property, all the way to the main sewer line. It plays an important role in sewer networks by preventing the build-up of harmful sewer gasses that can accumulate within drains.
If you want to build a new boundary trap, it must be within your property boundary.
Existing boundary traps should be moved inside your property boundary where possible.
Where a building is being refurbished and the shell is intact, a boundary trap can be in the road reserve outside the property boundary.
Traps allowed outside the property boundary
Where a boundary trap is allowed within the road reserve, the shaft must terminate 300 mm below the finished pavement level.
The trap position and depth must be clearly marked on an adjacent wall. The cover must be fabricated from cast iron.
If a building covers the entire site, a recess must be provided on the site so the boundary trap can be accessed at all times.
Connect a fire service
If you choose to connect a fire service on your property, it must comply with regulations.
A fire service is a privately owned asset to put out fires. This includes:
- hydrants
- sprinkler systems
- hose reels.
If you install a fire service, only isolating stop valves are permitted on the road reserve outside the property boundary.
All other valves, branches and metres must be located within the property boundary.
This applies to all new buildings and, where reasonably practicable, new services are installed in existing buildings.
If you want to install a fire service, contact your water provider. Refer to the National Construction Code for standards that apply to fire services.
