Monash University Caulfield Campus volume 186m3
Storm water harvesting from adjacent buildings for recycling as irrigation.

Point Park Mirvac at Docklands volume 362m3
An unusual variation. Because the site is at sea level, a storage system could only be installed above ground but the landscaping designers required the tank be out of sight. The problem was solved by creating an artificial landscaped mound of earth within which was installed a Rainstore3 system to store 341,000 litres.

Four workers with one small excavator took just six hours to install the 362m3 ready for enveloping and back filling.

Docklands Precinct VicUrban - total volume 704m3
Three installations are expected to harvest 10 million litres of water annually. Two were installed for storage and one to manage storm surge. This project won an SIAV award.

Moreland City Council Pentridge Redevelopment total volume 286m3
Rainstore3 offered a cost-effective solution to several sensitive issues. Council was concerned about ongoing maintenance costs and public liability issues of the Sedimentation Pond originally specified by Melbourne Water. Melbourne Water was concerned about run-off into the adjacent very sensitive (environmentally and politically) Merri Creek. By accepting our alternative solution, the developer, Pentridge Village Pty Ltd gained three additional building blocks, plus unencumbered additional recreation area and the marketing benefit of an innovative on-site stormwater treatment system.

Pentridge Village Pty Ltd calculated they achieved a net gain of over $465,000.00!

Plus, Melbourne Water achieved a greatly reduced environmental impact on the Merri Creek (than would have been achieved by the Sed Pond) in terms of suspended solids and nutrient release from the development. This was achieved by combining Rainstore3 with world-class, filtration systems (developed and produced in Melbourne by CDS Technologies Pty Ltd) and then utilising the filtered stored water for irrigation of surrounding parklands.

This installation won a Victorian Stormwater Industry Association innovation award for "Constructed WSUD in an established area".
