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.

We’re constructing a new stormwater drain and wetland in the Pioneer Bay area to improve flood protection, waterway health and stormwater issues. This continues our important work to provide flood protection to the community.

Why this is important

This project will divert flows from Colbert Creek through Pioneer Bay to a newly-established ‘wetland’ precinct. These works will complement the Bass Coast Shire Council’s Drainage Improvement Scheme for Pioneer Bay.

We are working closely with council to deliver this large-scale drainage project, and will do our best to plan the major construction activities to minimise impacts on local residents. 

What’s happening

This project involves:

  • remediating the Colbert Creek outlet to improve the function of the waterway and surrounding drainage
  • constructing a new wetland south of the estate on council land
  • landscaping and revegetating the constructed wetland
  • constructing a diversion pipe from Colbert Creek, running south along Bass Highway and connecting into the new wetland area
  • creating two levee banks approximately 1 to 2 metres high
  • new bunds (north and south side of depression), with pipe outfall from the depression to the existing pipe outfall to Western Port Bay
  • removing and pruning some trees along the updated works.

Major works on the waterway diversion are expected to commence in October 2020 and will be scheduled alongside the council’s drainage works to minimise disturbance to local residents.

The creation of the new wetland is expected to be complete by April/May 2021.

What to expect

We will make every effort to minimise impacts on community as we complete these works. However, you may notice some: 

  • access to driveways may be impacted temporarily
  • noise
  • dust – we will use dust suppression as necessary
  • increased truck movements 
  • traffic management on local roads 
  • removal and pruning of some trees along the stormwater pipe route.
