Green Gully Reserve in Keilor Downs is large enough to hold seven soccer grounds and a couple of cricket ovals as well as large swathes of parklands.

Stormwater captured from two nearby stormwater drains now keeps the reserve irrigated all year round. In 2013 the project was officially opened as part of an $8.4 million Brimbank Alternative Water Supply Project consisting of three stormwater harvesting schemes that were constructed to service Keilor Park Recreation Reserve, Green Gully Reserve and Keilor Public Golf Course within Brimbank.

The Green Gully project, devised and delivered by City West Water, diverts water from two adjacent stormwater drains to a holding pond, with a total capacity of 3 million litres. Depending on demand, water is thentreated and then drawn out for irrigation when needed.

With seven hectares of public open space under irrigation, it’s estimated the project results in more than 40 million litres of water saved each year – the equivalent of 16 Olympic sized swimming pools – and provides almost three quarters of the reserve’s irrigation needs.
