Sewer Connections in Brisbane
Connecting to the sewer, extending a line or diverting an existing one is a significant step for a property or development in Brisbane. The work depends on knowing where the connection point is, how deep it sits and what the surrounding levels allow, which can be challenging on sloping blocks. Good information makes planning easier.
Early planning helps avoid delays once excavation begins. If you are considering a sewer connection, extension or cut-in, share your plans and site details with us, and we can help you understand the scope of work involved. Understanding who is responsible for each stage early helps avoid unexpected delays.

What we handle
Sewer Connection Services in Brisbane
House Drain Installation
We install internal and external house drains for new builds, extensions and renovations, connecting all fixtures to the sewer correctly so wastewater flows freely and complies with Queensland plumbing regulations.
Sewer Relocations and Alterations
Building over or near an existing sewer can require relocation. We divert and reconnect sewer lines carefully, coordinating with the authority so your project can proceed without delays or defects.
Inspection Openings and Junctions
We install inspection openings, boundary traps and junctions in the right locations, making future maintenance, drain clearing and CCTV inspection easier and keeping your system fully compliant with local requirements.
Excavation and Reinstatement
We excavate around existing services, lay pipe on proper bedding and reinstate driveways, lawns, gardens and paving, so the connection is durable and your property looks tidy after the work.
Approvals and Compliance
We help coordinate inspections and documentation with authorities and builders, making sure your sewer connection is signed off correctly and your project keeps moving without costly rework or unexpected delays.
Connection point
Locating the sewer connection point on your block
Every sewer connection starts with knowing where the authority main or house connection branch actually sits. On older Brisbane lots the records can be incomplete, so on-site checks matter before design decisions are locked.
Start with the property’s available sewer plans from Queensland Urban Utilities, then compare them with what you can see on site. Inspection openings, raised risers and marked pavement can hint at the line’s direction. Records are sometimes approximate, particularly for older streets, so treat any plan as a starting point and confirm the position and depth physically before committing to a route.
- Check available plans
- Request the sewer plans for your lot and note any property connection branch, manhole positions and the stated depth of the main.
- Walk the boundary
- Look for inspection openings, risers and patched concrete near the front or rear boundary, and photograph each one with a reference point.
- Mark suspected routes
- Spray paint or pegs help everyone see the assumed line, and they stop other trades from excavating over it by mistake.
- Confirm before design
- Physical confirmation of position and depth can change fall, pipe length and cost, so it is worth doing before final layouts are fixed.
Cut-in works
Cutting a junction into a live sewer
A junction cut-in joins new pipework into an existing sewer line without replacing the whole run. It needs planning because the line may still be in service and the surrounding ground can be unstable.
Cut-in work usually means excavating down to the existing pipe, preparing the connection and supporting the surrounding soil, particularly in wet weather. Shoring may be needed in deeper trenches. Ask who will notify Queensland Urban Utilities or confirm approvals, how any flow is managed during the works and what inspection, if any, is needed before backfilling.
- Approvals and inspectionsConfirm who arranges any authority sign-off and when the pipe must remain visible so an inspection can happen before backfill.
- Shored trench safetyDeeper excavations near a live sewer often need support. Ask how the trench will be shored and kept dry in a storm.
- Condition of the old pipeOlder earthenware lines can be cracked or root-affected, and a camera check beforehand can show whether the connection point is sound.
- Protect existing servicesWater, gas and power lines may cross the area, so dial-before-you-dig information and careful hand digging help avoid costly strikes.
