Find out what's under the ground with the following services

Engineering search 

This service provides information about Urban Utilities water and sewerage pipes on and around your land. 

The information available includes, but is not limited to: 

  • Water network: as-constructed data, diameter, length, material and operating pressure.
  • Wastewater (sewer) network: as-constructed date, average depth, downstream and upstream invert levels, length and segment type.
  • Maintenance structures (manholes): manhole type, use, lid type, material, surface level and depth.
Please note: The service locations identified in the engineering search are approximate only and do not provide detail on existing private infrastructure (or infrastructure owned by other authorities), off-line mains, or assets owned by other authorities, such as Seqwater.  
For all of the private plumbing fittings, including mains to tanks, pipes up to your water meter and sewer connection point, as well as combined drains, contact the plumbing department of your local council for a copy of your house drainage plan.

If you are planning to carry out work on your land, we recommend undertaking an independent inspection at the site of your proposed works to avoid the risk of unnecessary delays and expense. Please contact your local council to obtain details of any private water and sewerage infrastructure.

Avoid risk and surprises with planning, research and site investigations

Things to consider:

  • Is there existing Urban Utilities infrastructure on or near your land? Our connection area maps may help to determine the drinking water, non-drinking water and wastewater services in your area.
  • The free Dial Before You Dig service can help identify infrastructure from other utilities (electricity, gas, telecommunications, etc).
  • Site-specific considerations may affect the complexity, cost and time of your development, e.g. easements, manholes and maintenance structures, heritage listing, protected vegetation, floodable land, acid sulphate soils, or site location relevant to waterways or major transport corridors.
  • Outstanding fees or non-compliance for existing development on your site may now be your responsibility.
