Drainage concept and functional design review and acceptance

Developers designing assets in line with a Development Services Scheme or to alter or decommission an existing Melbourne Water asset must apply for our comments and acceptance of those designs.

Drainage designs go through three stages of review and acceptance:

• Concept design

• Functional design

• Detailed designs submission

Concept design

The concept design process includes understanding the site, design configuration, confirming the location and size of the asset and if there is adequate land available. Concept designs can be submitted online for our consideration.

Functional design

Following the completion and approval of concept design, functional designs outline the functional elements of the system. These include calculations, modelling and design refinement to ensure full functionality and future maintenance of the assets. Functional designs can be submitted online for our consideration.

Detailed designs submission

Following the completion and acceptance of the Functional Design as well as the completion and acceptance of a Works Offer, Detailed Design plans can be submitted online for our consideration via the Design and Construction Hub.

• additional information such as relevant technical reports or correspondence (such as approvals from relevant authorities) as applicable to the asset type and the site. 

All applications must be submitted online via our website and ensure they are prepared in conjunction with the relevant section of the Developer Minimum Application Requirements Guideline (478.38 KB, PDF).
