As a result of the recent high rainfalls and subsequent flooding Melbourne Water is working with emergency services and other relevant agencies to review the impacts to our waterways and assets. 

For flood or storm emergency assistance, contact the VIC SES on 132 500 and for life threatening emergencies call 000. 

You can access current emergency information by calling the VicEmergency Hotline on 1800 226 226 or sign up to receive regular updates regarding flooding via the emergency.vic.gov.au website and app.

Building surveyors must consult with Melbourne Water prior to issuing a building permit. This is to ensure that the proposed development design has considered the impacts of flooding and assets such as waterways or drains.

​A building permit application is referred if the proposed site is land liable to flooding and the land abuts a waterway or is within 20 metres of an asset or waterway (Regulation 154).

Council or building surveyors are required to consult with us to obtain flood level information. This information will assist in the setting of floor levels to protect against flooding (Regulation 153).
