New Water Main Installation
We install new water mains to service developments and properties, laying pipe to the required depth, level and alignment and completing connections to the existing network to current authority standards.

Water Main Extensions in Brisbane
Extending a water main is a common requirement for new developments and larger sites in Brisbane where the existing Queensland Urban Utilities supply does not reach. The work involves understanding current capacity, expected demand and the best route for new pipework. Good planning avoids delays later.
Because authorities, designers and contractors may all be involved, clarity at the start helps the project run smoothly. Share your plans and any servicing information you have with us, and we can help you plan the extension work. Early conversations with the relevant authorities can also help you understand what is required for your site.

What we handle
Water Main Extension Services in Brisbane
Property Service Connections
We run water service lines from the main to your meter and property boundary, installing the necessary fittings and valves so your new home or building has dependable, safe water.
Trenching and Pipe Laying
Our experienced crews excavate trenches, prepare bedding, lay pipe and backfill in carefully controlled layers, building a sound installation that withstands traffic loads, ground movement and long-term pressure for decades.
Pressure Testing and Disinfection
We test new mains for leaks and pressure, and coordinate flushing and disinfection requirements, so your extension is approved for service and delivers safe, clean drinking water to every connection.
Road Crossings and Reinstatement
We plan crossings carefully, protect existing services and reinstate roads, driveways and verges after pipe laying, minimising disruption to traffic and neighbours and leaving the whole site safe and tidy.
Hydrants and Valves
We install valves, hydrants and fittings where required by the design, positioning them for access and operation, and helping your water network meet performance and safety requirements from day one.
Supply information
Reading Queensland Urban Utilities supply information
Before planning any extension, gather what is known about the existing water network near your site. Good information shapes the route, the size of pipe and the conversations with the authority.
| Request the plans | Ask for water main information near your lot and compare it with what is visible, such as meters, valve covers and hydrants. |
|---|---|
| Note pipe size and material | The size and age of the nearest main influence connection options and how much extra demand it can serve. |
| Photograph existing fittings | Pictures of meters, hydrants and valve covers around the site help designers understand the existing network. |
| Clarify requirements early | Ask the authority what applies to your development before design starts, so approvals are not left until after the drawings are done. |
Route planning
Routing a new water main across your block
The path a new main takes across a property affects cost, disruption and future access. A route that looks shortest on paper may be difficult once trees, slopes and structures are considered.
Walk the proposed route and note trees, retaining walls, existing services, steep banks and areas prone to boggy ground in the wet. Pipes generally need cover and clearance from other services and structures, and access must remain for future maintenance. Compare alternative routes with the designer, since a slightly longer path can sometimes avoid major obstacles.
Walk the route
Walking the line with the designer exposes obstacles such as large trees, retaining walls and drainage lines.
Cover and clearances
Pipes need adequate cover and separation from sewers, gas and power, which can limit where a route may go.
Think about maintenance
Avoid routes under future buildings or slabs, so the main remains reachable if repairs are ever needed.
Wet-weather ground
Clay in storm season can make trenches unstable and difficult to access, so consider timing for excavation.
