Drainage design review and acceptance

Developers designing assets in line with a drainage scheme (also known as 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

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

Following the completion and acceptance of the Functional Design, Detailed Design plans can be submitted online for our consideration.
