Super-sized CDS® unit future-proofs major Melbourne business park

The development of a large business park precinct within the Tullamarine Airport land has resulted in a contract to supply the largest CDS® Gross Pollutant Trap (GPT) that Rocla’s Campbellfield team has ever undertaken in metropolitan Melbourne.

“With a catchment area of around 200 hectares to service, a CDS® P3024 Unit was needed to meet infrastructure demands for both present and future use of the development,” said Andrew Clifton, Market Development Engineer for Rocla Water Quality.

“When you look at the unit itself, plus all of the additional precast concrete components, such as the diversion chamber, this is one of the largest CDS® Units sold by Rocla in Australia,” he said.

The project is being undertaken by asset owner APAM (Asian Pacific Airports Melbourne), with Spiire Australia developing the initial drainage strategy and being subsequently engaged to undertake detailed design.

As well as creating a major new business park precinct for Melbourne’s West, the project will result in a second entrance to the Airport, relieving congestion on the main entrance via the Tullamarine Freeway.

The integrated stormwater management system emphasises best practice water quality targets and includes a 100,000 cubic metre retarding basin as part of the design.
