What it is
Getting power, water, comms ducts and gas lines from the boundary into a new building, in the right trenches at the right depths, before the slab goes down and the landscaping goes in.
When you need it
- A new house or minor dwelling needs every service brought from the street.
- A builder wants one contractor for all the underground connections.
- A subdivision lot needs ducts and pits ready for future connections.
What you get
- All services trenched, laid and connected to the point your trades need.
- Water pressure-tested, power protected, ducts proven and capped.
- An as-built record of where everything was laid.

Our Projects
South Auckland
Auckland Residential Water Mains Replacement
After the aged water mains at a residential property in South Auckland had many failures, Utility Works was contracted to renew the system. The project involved services detection, concrete cutting, and hydro-vac trenching to minimise risk and damage to other services in the work zone. The new water mains were installed with a new inlet valve, toby, and relayed concrete, and the property reinstated to its original condition.

North Waikato
Rural Power Mains Installation in North Waikato
Utility Works was commissioned to install a new power mains cable on a rural North Waikato property. The project involved existing services detection, excavator trenching, and hydro-vac works to keep the trench clear due to in-flow during the project, followed by installation of the three-phase cable and final connect and commission. The project was completed on time and within budget.
