$10m project to protect Karaaf Wetlands, Surf Coast water supply

A NEW $10 million infrastructure project will reduce stormwater runoff into the Karaaf Wetlands and boost water reuse across the Surf Coast region.

The Growing the Surf Coast Hinterland and Protecting the Karaaf project will receive $5 million from the federal government and $5 million from the Victorian government as part of the national Water Infrastructure for Sustainable and Efficient Regions program.

The wetlands are a significant coastal saltmarsh ecosystem that has been affected by excessive freshwater flows caused by stormwater drainage from housing developments in Torquay

Corangamite Labor federal member Libby Coker said the investment would improve water quality and help protect the local environment.

“This project will breathe new life into the Karaaf coast saltmarsh, and the ability to harness up to 400 megalitres of alternative water will unlock new opportunities for productive use.”

The new infrastructure will include a stormwater reuse system and a recycled water pipeline, as well as upgrades to an existing recycled water plant to increase capacity.

It is expected to reduce the volume of stormwater entering the wetlands by 40 to 50 per cent, allowing the saltmarsh to return to more natural cycles.

Save the Karaaf convenor Andy McCauley welcomed the announcement, saying it marked a major step forward in reusing stormwater across the coast.

“This $10 million will be fantastic,” he said.

Mr McCauley said the investment would deliver long-term environmental and industry benefits.

“It’ll be good for the Karaaf. We don’t have enough water – stormwater is a great resource.”

The project builds on an earlier $1.9 million federal government investment under the Urban Rivers and Catchments Program, aimed at improving the ecological condition of the Karaaf Wetlands.

Federal Environment Minister Tanya Plibersek said the project would benefit both the environment and local communities.

“These infrastructure projects allow us to get on the front foot and efficiently deliver secure water to Australian communities, with big benefits for the environment and our transition to a circular economy,” she said.

The system will also make up to 400 megalitres of alternative water available for productive use in the Surf Coast Hinterland, easing pressure on drinking water supplies.

Barwon Water chair Jo Plummer said the investment would support the region’s long-term prosperity.

“Maximising the use of recycled water will support new housing, agricultural production, tourism-led ventures and our region’s prosperity.”
