Services

Four disciplines, one contractor on site

Water, sewer, stormwater and the earthworks around them are quoted and delivered by the same team, so the trench, the pipework and the reinstatement answer to one program and one supervisor.

Who we work for

Six kinds of client, one standard of documentation

Developers

Subdivision and townhouse servicing from the connection point to the lot boundary, sequenced around your civil program and authority inspections.

Head & civil contractors

A wet-services subcontractor who reads the same drawings you do, prices variations in writing and keeps ITPs and as-constructeds current.

Councils & government

Maintenance, renewal and repair work on public drainage and water assets, delivered with traffic control, permits and site records in place.

Homeowners

Collapsed drains, blocked sewers, yard flooding and new connections, explained in plain language before anyone opens the ground.

Property managers & body corporates

CCTV evidence and written scopes for recurring blockages, so committees approve repairs on facts rather than guesswork.

Plumbers subletting civil work

Machine work, deep trenching and mains connections for plumbing businesses that keep the client relationship and hand us the dirt.

The process

How a civil plumbing job runs, start to sign-off

  1. 1

    Scope and site check

    We read the hydraulic drawings, walk the site and confirm access, depth, surfaces and the connection point before pricing anything.

  2. 2

    Written quote and program

    Inclusions, exclusions, plant, spoil and reinstatement are itemised, with the assumptions listed so nothing turns into a surprise claim.

  3. 3

    Permits, locates and set-out

    Before You Dig plans, authority approvals, traffic control and service location happen ahead of the machine arriving, not during the dig.

  4. 4

    Install, test and inspect

    Trenching, bedding, laying, pressure or CCTV testing and inspection are recorded as the work proceeds, section by section.

  5. 5

    Backfill, reinstate, hand over

    Compaction, surface repair and a clean site close the job out, with as-constructed detail and test records issued for your handover file.

Cost drivers

What actually moves the price of underground work

Two trenches of identical length are priced differently for reasons that have nothing to do with the pipe. Depth, ground conditions and what sits above the alignment carry most of the cost. We quote each job on site rather than publishing a rate that would be wrong for yours.

Get a written quote Read the guides
Depth and trench support
Past roughly 1.5 m the trench needs shoring or benching, which changes the plant, the crew size and the volume of spoil.
Ground conditions
Redlands rock, reactive clay and high water tables each demand different attachments, dewatering and import material.
Existing services in the alignment
Live water, gas, comms or electrical crossings force hand excavation, non-destructive digging and slower progress per metre.
Surface type and reinstatement
Turf is cheap to restore. Concrete driveways, asphalt road pavement and council footpaths carry saw-cutting, disposal and replacement costs.
Access and traffic management
A tight infill block or a live road reserve adds smaller machines, permits, traffic control and out-of-hours work.
Authority approvals and inspections
Connection applications, hold points and inspection lead times set the program, and the program sets the standing time.

Standards & compliance

Work that passes inspection the first time

Underground work is buried within days of being installed, so the record of how it was built matters as much as the build. Every job is set out against the approved drawings and closed out with test results and as-constructed detail.

  • AS/NZS 3500 plumbing and drainage

    Grades, bedding, materials and testing follow the standard, and the work is carried out under QBCC occupational licence PD21658, held in both the plumber and drainer classes.

  • Water authority and council requirements

    Connections, permits and inspections are handled through the relevant authority — Urban Utilities, City of Gold Coast, Redland City Council or Logan Water — depending on where the job sits.

  • Before You Dig Australia searches

    Service plans are pulled and verified on the ground before excavation, and crossings are exposed by hand or non-destructive means.

  • Safety and site documentation

    SWMS, excavation and confined-space controls, traffic management plans and daily records travel with the crew, ready for your site induction.

  • Test and handover records

    Pressure tests, CCTV footage, compaction results and as-constructed marked-up drawings are issued at completion for your handover file.

Common questions

Answers before you call

The questions below come up on nearly every enquiry. The full list covers approvals, testing, timeframes and what happens when a job hits rock.

All questions
What is a civil plumber?

A civil plumber installs and maintains the underground water, sewer, drainage and stormwater infrastructure that connects buildings to public networks. The work sits between a domestic plumber's fixtures and a civil contractor's earthworks, and it is licensed, tested and inspected accordingly.

Do you work as a subcontractor to builders and civil contractors?

Yes. Most of our work is wet services delivered under a head contractor or builder, including trenching, mains, sewer, stormwater and reinstatement. We supply insurance details, SWMS and inductions before mobilising.

How much does a sewer or stormwater connection cost?

Price is set by depth, ground conditions, existing services in the alignment, surface reinstatement and authority requirements rather than by length alone. We quote in writing after a site check, with inclusions and exclusions listed. See what drives cost.

Do you handle council and water authority approvals?

We lodge connection applications, book inspections and coordinate hold points with Urban Utilities, Logan Water, Redland City Council or City of Gold Coast, depending on the location of the job.

Can you locate a blockage without digging up the yard?

CCTV inspection and above-ground locating identify the defect, its depth and its position before excavation starts. You receive the footage and a written scope, and only the section that needs repair gets opened.

Which areas do you service?

Brisbane, the Redlands and Bayside, Logan, Ipswich, the Gold Coast, the Sunshine Coast and Toowoomba, worked out of Capalaba. Projects outside that radius are considered on scope and duration — send the details.

Send the drawings. We will price the dirt and the pipe.
