Before you dig, drill, or develop, know what’s below. In Western Australia, there’s a complex web of underground utilities that keep our homes, businesses, and communities running. Accidentally damaging one of these services isn’t just costly, it can be dangerous and put your entire project on hold. That’s why underground service location is essential before starting any excavation, trenching, or site work. At DJL Electrical, we provide accurate, professional service locating to help you avoid disaster and stay compliant. Here’s a breakdown of what can be detected underground, and why it matters.
Underground Power Cables
Power cables are one of the most critical, and hazardous, utilities to locate. Striking a live cable can cause serious injury, outages, or even death. In WA, underground electrical infrastructure may include:
- Low and high-voltage power lines
- Consumer mains and sub-mains
- Street lighting and service pillars
Water Pipes
Underground water mains and supply lines are essential for residential and commercial properties. Damaging them can lead to flooding, site delays, and expensive repairs. These include:
- Potable water supply pipes
- Fire service pipes
- Irrigation lines
Gas Lines
Natural gas lines are often shallow and can run through backyards, footpaths, and easements. Hitting a gas line can cause leaks, fire risks, or site evacuations. These may include:
- Mains gas supply for residential areas
- LPG service lines for commercial setups
Communications and NBN Cabling
In today’s digital world, cutting through comms cabling doesn’t just knock out someone’s Wi-Fi, it can shut down businesses and essential services. Underground communication lines include:
- NBN and fibre optic cables
- Copper telephone lines
- Security and data cables
Who Needs Underground Service Location?
- Builders and electricians
- Landscapers and earthmovers
- Plumbers and irrigation contractors
- Homeowners doing renos or landscaping
- Developers preparing new lots or subdivisions
