Building over pipes and easements

If you are planning to build a house or structure that will be located over or adjacent to (within the zone of influence) of one of our assets, you will need to lodge a build over asset application. The zone of influence is the area above and beside an asset where loads may have an impact on that asset. Generally this will be 1.5 metres either side of the main. We will need to review your plans and assess your application to be able to advise you of any relevant conditions or restrictions on the building application.

In order for us to assess your application, you will need to provide us with at least one full set of plans. You may need to submit multiple copies as some councils require more than one set of plans with the Hunter Water stamp on them. Check your council’s requirements before submitting your application to us. We will then assess your application and advise you of your specific requirements.

If you are planning to build an additional residence or a development (such as a duplex or granny flat) you will need to lodge a Development Assessment Application (see our FAQ's below for more information).
