​You need our formal approval before you can work on any new or modified stormwater connection.

With the continuing development of new housing in green field areas and also in-fill housing in brown field areas, developers need to design drainage systems to manage the quantity and quality of stormwater entering receiving waters. ​Open waterways, channels and underground drains are part of the stormwater system. 

Application process

Step 1

For any new or modified stormwater connection, developers need to contact their local council, who will nominate the legal point of stormwater discharge,

Step 2

If the local council nominates one of our drains or watercourses as the legal point of discharge:

  1. developers will need our formal approval before they can work on our drainage system. 
  2. developers will also need to apply to us for upgrades to existing connections to our stormwater system. 

Note: connection to our drainage asset is normally through an outlet to a surface channel (either natural or constructed), or an inlet to an underground pipe system. 

Connections must meet our technical requirements, however may differ depending on whether a stormwater outlet or inlet is being built. 

Important: Works can only be performed by our Eligible Drainage Contractors. All contractors who carry out works on live assets are required to have the required authorities to work.

Prior to the commencement of works on Melbourne Water’s asset, the contractor must contact Melbourne Water’s Asset Services Team on 131 722 for approval to work on a live asset(s). Inspections will be undertaken at different stages of the works. The letter of approval will confirm requirements. Penalties apply for un-authorised works. Any works undertaken without Melbourne Water approval will be considered illegal under the Water Act 1989.
