Building over pipes and easements

If you are planning to build a house or structure that will be located over one of our assets, you will need to lodge a build over asset application. 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.

You will need to include at least one full set of plans with the application. 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 with any relevant conditions or restrictions on the building application.
