If you plan to construct a crossing over our drain or waterway or to make any changes to an existing crossing, you must get our approval.
A crossing is any bridge or culvert passing over a creek, river, stream, or formed channel on our land.
This is how we protect our waterways and drainage assets and ensure any proposed work meets our standard requirements.
Any works undertaken without Melbourne Water approval will be considered illegal under the Water Act.
Your plans will need to meet our standard guidelines - the technical and design requirements for building waterway/drain crossings.
Approvals from other authorities
We may need evidence of approvals from other authorities or private owners who may be affected by your works before we provide approval.
Check that you comply with other laws that may affect your development, such as Special Building Overlay and Land Subject to Inundation Overlay.
You should ask your local council if you need a planning permit before construction.
We are transitioning to online delivery of Agreements via a secure encrypted platform, which will enable faster execution. During this process, you may receive an email from ‘DocuSign EU System’ containing your Agreement. For more information contact our Customer Service Centre on 131 722.
We consider various types of crossings depending on how they will be used and the waterway or drain characteristics.
- environmental impacts
- impact on flood levels to surrounding properties
- maintenance access
- safety and risk criteria
When you submit your conceptual plans we will review them and respond with any requirements.
Documentation that you will need to supply includes:
- a cover letter outlining the proposed works
- measurements of the cross section or creek profile
- location of underside of bridge to Australian Height Datum
- exact location of works (include Melways reference if known)
- location of abutments/piers in regard to top of bank
- photos of the proposed site
- extent of proposed rock work
- conceptual design (rough sketch)

- preliminary environmental assessment
