Building over pipes and easements
There are many conditions to building over our assets. Find out just what these are and the applications you'll need to submit to have your construction plans reviewed.
When is a Building Over Assets application required?
Any development within Hunter Water's area of operations requires plan stamping by Hunter Water so that we can confirm that water and sewer services are available and that our assets will be protected. Developments will typically follow one of three pathways;
- Single residential developments (new residential house, pools, extensions, retaining walls, etc) not building over or adjacent to our assets = plan stamping only
- Single residential developments (new residential house, pools, extensions, retaining walls, etc) building over or adjacent to our assets = plan stamping and Build Over Assets application
- Subdivisions, multi-residential (duplex, granny flat, units, etc), commercial or industrial developments = plan stamping and Development Assessment
Our Land Development Team will assess all Build Over Asset and Development Assessment applications and provide the requirements for each type of development. The Development Assessment application process incorporates any build over asset assessment in this application.
Our preference is that none of our assets are built over, however we know that sometimes that is not possible. Depending on the type of development and the risk to our assets you may have the below requirements;
- Relocate the development clear of our assets - re-submit the new plans once you have re-designed
- Relocate the asset - done under a Developer Deed
- Replace the asset - done under a Developer Deed
- Take caution and care of our assets both during construction and ongoing. Don't place any additional loading (force) on our asset by designing footings or piers accordingly.
Typically, Hunter Water will not require the concrete encasement of sewer mains unless specifically directed.
Information about the zone of influence
The zone of influence is the area above and beside an asset where loads may have an impact on that asset. Generally we apply a 1.5 metre clearance either side of the main however several factors need to be determined. We will need to review your plans and assess your application to be able to advise you of any relevant conditions or restrictions for the development.
How do I know where Hunter Water's assets are?
If you are unsure if your development will clash with our assets, you can request a Service Location Plan to provide a map of where Hunter Water assets are located on and surrounding your property.
Did you know?
If your development is over or within 1.5m from the centre of a sewer manhole/maintenance structure or within a Hunter Water Easement, you typically will not be able to construct or develop.
