Don't hit a water main by accident

Always check before you start excavating to make sure you don't accidentally damage underground pipes, cables or other utility services. You may be financially responsible. Whether you're installing a pool, or working on a commercial site or in the road reserve, get plans of our assets online for free from Before You Dig Australia (BYDA).
