EVERY year, about 500 billion litres of stormwater washes off the roofs, roads and footpaths of Melbourne into our rivers and bays.
That’s about the same amount of water that Melburnians consume each year.
Often it comes in a thunderous rush, surging out of drains, damaging waterways, and pouring litter into Port Phillip and Western Port bays.
But a $20 million bid to use Melbourne’s stormwater on “rain gardens” across the metropolitan area has gathered speed since early last year.
Rain gardens are designed to absorb large volumes of water from downpipes, road surfaces and paved areas.
