Follow these simple steps

Excavator diggingContact Dial Before You Dig (DBYD) to order a plan before you start any digging.

The free DBYD plan will locate underground utilities (pipes, cables) on your property. It provides information about the presence of underground infrastructure only; it does not pinpoint the exact location. You should use these plans as a guide only.

If the Dial Before You Dig plan shows Unitywater infrastructure on your property (water mains, sewer mains, manholes), and you need more detailed information about the location of our infrastructure you can:

  • use our free online mapping tool (step 2 below) to show the location of our underground water and sewerage infrastructure
  • or, if you need an official PDF version of the map emailed to you then you can buy a Detailed Infrastructure Plan (step 3 below). The online mapping tool and Detailed Infrastructure Plan contain the same information. 

More information about DBYD  

  • If you have not ordered a Dial Before You Dig plan, you can come straight to us to use our map or order a Detailed Infrastructure Plan (DIP).
  • Lodging a standard DBYD enquiry is free
  • Dial Before You Dig aims to prevent damage and disruption to essential underground services.
  • It is not a Unitywater service, but DBYD plans will display Unitywater infrastructure.
  • You can request a DBYD plan for private property as well as for public land, including parks and sections of road.
  • Note: Assets belonging to Main Roads or Queensland Rail will not be provided on Dial Before You Dig plans because these bodies are not members of the DBYD group.

5. Your address will be pinpointed and you will be able to see the surrounding water and sewerage infrastructure. The legend on the right hand side can help you: For example:

  • blue lines are the water pipes

6. If you find your address on the map and you cannot see any blue or orange lines running near the property (example below) this indicates there is no Unitywater infrastructure on or near your address.

7. If you cannot find your address on the map this indicates Unitywater has not received the necessary information to update our records. This can happen in the case of new developments or housing estates. Please contact the property developer to discuss. 

If you still need an official PDF version of the map emailed to you then you can order a Detailed Infrastructure Plan (DIP). There is a cost for a DIP (click on GIS Mapping Services) and a 5 day turnaround. Please note: the online mapping tool has the same information that would be provided in a DIP and can be exported as a PDF or printed.
