Cut in Junctions

Cut-in Junctions Services - Zaoud Plumbing, Sydney Water Accredited

What Is a Cut-in Junction?

A cut-in junction, sometimes called a junction cut-in or property connection point (PCP), is the process of creating a new connection point from a building’s plumbing or sewer sideline into an existing sewer main. This junction allows wastewater from your property to safely and legally discharge into the public sewer network.

While the main sewer is maintained by Sydney Water, cut-in junctions fall under the works required by developers, builders or property owners as part of new builds, subdivisions or alteration projects.

In Sydney’s Minor Works Sewer regime, accredited constructors (like Zaoud Plumbing) are permitted to insert junctions into existing VC or PVC sewers under certain size and depth limits.

Why a Cut-in Junction May Be Required?

You are building a new house, granny flat or duplex and need a legal sewer connection to the main line.
Your subdivision or development requires additional connection points to the main sewer.
Your existing plumbing is being altered or extended, requiring a new junction location.
Your site plans or setbacks conflict with current connection points, so you must relocate or create a new junction.
Sydney Water or a Water Servicing Coordinator (WSC) mandates a new junction or cut-in as a condition of approval (for DA, Section 73 works, or minor works).

4. Trench works & exposure

Excavation to expose the existing sewer main in a controlled manner
Use shoring or trench safety measures where needed, especially in deep excavations or near adjacent infrastructure

5. Junction cutting & insertion

Carefully cut into the sewer main per approved design. Use proper tools (e.g., saws, core drills) to avoid damage or debris falling into the pipe.
Install the junction fitting (e.g. saddle, T-piece), ensuring watertight seal and alignment.
Connect your sideline or property connection to the new junction using approved pipes, joints and gradient

6. Inspection

Coordinate with WSC or Sydney Water to inspect the junction and approve the works.
Provide as-constructed plans, test reports, and compliance documentation.

7. Backfill & surface restoration

Backfill carefully in layers (lifts), compacting per specification.
Temporary restoration services surface finishes such as paving, lawn, driveway, or landscaping.

Accessibility — tight sites, adjacent structures, limited working room
Safety and shoring requirements for deep trenches
Volume of backfill and reinstatement work
Permit, inspection, design or coordination overheads
