Building over an easement
You can save both time and money by learning about building near or over easements/assets.
Frequently Asked Questions
- Is lodging a Build over Easement application regarded as an approval to build?
No. City West Water will need to assess your proposed plans to ensure they comply with the Build over Easement guidelines. Amendments to your plans may be required. An approval will only be issued once all our requirements have been met.
An encumbrance will be recorded on the property, informing any future owner of the property of the existence of the build over easement agreement/approval.
- How can I find out information such as location, depth, size and grade of sewer mains and property connections?
This information can be provided by completing a Sewer Details Asset Information application.
For information on other utilities such as stormwater drains, underground electricity, gas or telecommunications, please contact the appropriate utility provider.
- I am proposing to do some landscaping over a sewerage easement. Do I need to submit a Build over Easement application?
Yes. But only if you are building a structure, e.g. a retaining wall or a garden bed (greater than 300mm high) or placing a fill/site cut greater than 300mm over an easement.
- What do I need to include when submitting a Build over Easement application?
You are required to submit a PDF copy of the full set of architectural and engineering drawings showing all structures and all offsets to all boundaries. Footing details must be provided. Please note that preliminary drawings will not be approved.
I am proposing to install a small garden shed over the easement that I have purchased from a hardware store. I do not have any architectural plans for it. What details do I need to provide you?
If you have purchased a small DIY garden shed and placing it over the easement, you will need to supply City West Water with a site plan showing where the shed is going to be located. This should include offsets from title boundaries, the shed size (L x W x H) and the type of footing required, eg. 100mm paving slab. We will also need a copy of the shed pamphlet/catalogue.
- Why does my footing depth need to achieve angle of repose?
Angle of Repose is the line of influence from the sewer pipe. Generally an angle of 45 degrees taken from the edge of pipe.
If your proposed structure is considered a heavy structure i.e. brick garage, you are required to deepen the footings to achieve angle of repose in relation to the sewer pipe depth.
Angle of repose is required to protect your structure from subsiding and/or being undermined if maintenance works are required to the sewer main. By having deepened footings below the zone of influence it ensures the structure is self-supporting.
