We take nearly 70 per cent of the water from underground sources, called aquifers, 23 per cent from rivers and seven per cent from storage reservoirs.
Each day we also treat and recycle 718 million litres of wastewater at 365 treatment works after it is pumped through a network of 2,375 pumping stations and 39,600 kilometres of sewers.
