In late January 2018, John Holland-KBR Joint Venture (JH-KBR JV) delivered upgrade works to the Fairbairn Road retarding basin (within the J and P Cam Reserve) at Cranbourne, on behalf of Melbourne Water. The upgrade works ensured the retarding basin continues to reduce the risk of flooding to the community.
This work is now complete.
Why we are doing these works
Melbourne Water has over 200 retarding basins that we regularly assess for risks, conduct maintenance on, and upgrade as necessary. The Australian National Committee on Large Dams (ANCOLD) guidelines represents the best Australian and international engineering practice in the safe design, management and operation of dams. We use these guidelines to manage our retarding basins.
The Fairbairn Road retarding basin has recently been assessed against the ANCOLD guidelines. This assessment has shown that upgrade works are necessary to ensure the retarding basin continues to reduce flood risk and operate safely for the community.
