South-east Queenslanders have stuck to their water-saving ways since the 2001-2009 drought and in 2015 are using almost half the water per person they used when the last drought started in 2001.

In 2001 the average person used 300 litres of water per day to wash, eat, drink and in the garden.

In 2015 – according to figures released by Seqwater on the eve of an international water conference in Brisbane this week – each person uses just 169 litres per day.

That water saving – started by water restrictions to get homes in Southeast Queensland to use 130 litres per person per day - effectively means Southeast Queensland now does not need a new drinking water dam until 2030.
