The City of Melbourne has installed a five million litre stormwater harvesting and reuse system in its Fitzroy Gardens redevelopment unveiled by Lord Mayor Robert Doyle.
Mr Doyle said the underground stormwater tank would future-proof the 167-year-old gardens from the impacts of climate change.
โMelburnians and visitors love the Fitzroy Gardens and this multimillion dollar redevelopment means they will continue to enjoy green parklands with excellent visitor facilities for generations to come,โ Mr Doyle said.
โThe stormwater tank is twice the size of an Olympic swimming pool and provides half the annual watering needs of the Gardens.
โIt will save 59 million litres of potable water each year to keep the gardens lush and green.โ

I thought this was recently completed? It’s been going on for years and the visitor centre is now open.
