COVID-19 update: As an essential service provider, we are continuing construction and field work where it is safe to do so. We’re following up-to-date State health advice, including specific hygiene and social distancing protocols. Read more.

Why this is important

The aim of this project is to improve flood protection, waterway health and storm water issues by diverting 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 organise the major construction activities to minimise impacts on local residents. 

What's happening 

  • Remediation of the Colbert Creek outlet to improve the function of the waterway and surrounding drainage.
  • Construction of a new wetland south of the estate on Council land.
  • Undertake landscaping/ revegetation of constructed wetland.
  • Construction of a diversion pipe from Colbert Creek running south along Bass Highway and connecting into the new wetland area.
  • Creation of two levee banks approximately 1-2 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.
  • Removal and pruning of some trees along the updated works.

Major works on the waterway diversion are expected to commence late September 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.
