Staged delivery
How civil plumbing works are delivered
Underground work is unforgiving — most of it is invisible the moment it is finished, so the sequence matters.
-
01
Set out from plans
Service routes, levels and connection points marked from the drawings and checked against what is actually in the ground.
-
02
Excavation and trenching
Trenches opened to the required depth and grade, with existing services located first.
-
03
Install and inspect
Mains and service lines laid to fall, bedded correctly, and inspected before backfill.
-
04
Backfill and reinstate
Compacted backfill and surface reinstatement, with as-built information recorded.
What is included
What civil plumbing covers
-
Underground mains
Water and sewer mains and service connections across a development.
-
Stormwater and drainage
Stormwater lines, pits and legal points of discharge.
-
Subdivision plumbing
Service runs to individual lots on new estates and multi-dwelling sites.
-
Service connections
Connecting new work to existing mains and authority infrastructure.
-
Inspection and testing
Work inspected before backfill, because after backfill it is expensive.
-
Documentation
Records and certification for the works completed.
Technical planning
What we resolve before breaking ground
Almost every expensive civil problem is a planning problem that was found late:
- Location of existing underground services before excavation
- Depth, grade and fall across the full run, not just at the ends
- Legal point of discharge and authority connection requirements
- Trench support and safety for the depth involved
- Reinstatement standard expected for the surface above
Compliance
Getting it right before it is buried
Civil plumbing is carried out by VBA-licensed plumbers to the applicable Australian Standards, and drainage is inspected before backfill so defects are found while they are still cheap to fix.
Falls, bedding and materials decide whether an underground line still runs in twenty years. They are set to the drawings and checked, not estimated.

Why Ozra
The plumber that shows up, fixes it right, and charges what they quoted
Most complaints about plumbers are not really about plumbing. They are about not knowing when someone will turn up, what the bill will be, or whether the problem is actually fixed or just quiet for a fortnight. These are the eight things we hold ourselves to on every job, emergency or planned.
-
True 24/7 emergency cover
Plumbing emergencies don’t wait for business hours. Nights, weekends, and public holidays included.
-
VBA-licensed on every job
Every repair and installation is performed by a VBA-licensed professional to Australian safety standards.
-
Fixed, upfront pricing
A fixed-price estimate before we start. No hourly surprises and no hidden call-out fees.
-
60–90 minute response target
For urgent emergencies like burst pipes or gas leaks, we aim to be on-site within 60 to 90 minutes.
-
Diagnose first, then fix
Acoustic, thermal, and CCTV diagnostics find the actual fault before anything is cut open or replaced.
-
Workmanship guarantee
Every repair is backed by our workmanship guarantee and meets Australian safety standards.
-
Explained in plain terms
We diagnose the issue and explain the practical options in language that isn’t trade jargon.
-
Left the way we found it
The work is completed properly and the space is left in order before we hand it back.
