Patterson Lakes Tidal Gates- corrosion protection works

Shape Copy 3 Future

To continue our important work of maintaining and improving our infrastructure and assets, Melbourne Water will be conducting corrosion protection works on the Patterson Lakes tidal gates. This work will involve re-coating the gates with an anti-corrosive paint.

The tidal gates are located at Whalers Cove (Tidal Waterways), Runaway Bay (Marina) and Town Centre. These large mechanical gates serve to protect the community from localised flooding.

What’s happening and when

This work will be staged and will commence at Whalers Cove western gate.

Tidal gate Commences Length of work
Whalers Cove (western gate) March 2020 16 weeks

 

As Whalers Cove has two sets of tidal gates, Melbourne Water will be completing one at a time to maintain vessel access to and from Whalers Cove. Each set of tidal gates will take approximately 16 weeks to upgrade.

Melbourne Water also plans to upgrade the tidal gates at:

  • Whalers Cove (east)
  • Runaway Bay
  • Town Centre.

We will continue to keep the community updated as more information becomes available.

Why is this work necessary?

To ensure safe and reliable operation of the Patterson Lakes Tidal Gates, Melbourne Water undertakes a regular maintenance regime.

Every three months, divers inspect and descale the gates with minimal impact to boat users. Additionally, these inspections help determine when further anti-corrosion works are required.

Recently inspections have found that a new coat of anti-corrosion paint is now required to ensure the gates continue to protect the community.

What do the works involve for Whalers Cove (western gate)?

To prepare for painting the tidal gates, the following activities will take place:

  • installing drop boards to block sea water from flowing near the gates while they are being painted and drying
  • desilting and cleaning the gates.

Prior to these works, other activities will occur such as:

  • ground investigation works in the areas where cranes will be placed
  • construction of temporary access tracks and platforms to enable workers to safely conduct their activities
  • drop board testing.

Melbourne Water will make every effort to minimise impacts to the community as we complete these works, however you may notice some:

  • dust
  • noise
  • intermittent closures of the Dandenong Creek Trail
  • increased truck movements through the access points to the tidal gates
  • partial closure of the tidal gate at Whalers Cove.

Keeping you informed

Melbourne Water would like to thank everyone affected by this project for their patience during the construction period. We will keep you updated regularly as the project progresses.
