Melbourne Water has upgraded the Pembroke Retarding Basin to ensure it continues to reduce the risk of flooding to the community

Why did we upgrade the Pembroke retarding basin?

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 Pembroke retarding basin was recently assessed against the ANCOLD guidelines, which found that upgrade works were needed to ensure the retarding basin continues to reduce flood risk and operate safely for the community.
