The rain has stopped pouring and the water is running low. This week NSW Premier Gladys Berejiklian decided to fast-track the implementation of Level 2 water restrictions in Sydney. The new restrictions take effect from December 10 and apply to water use outside the home, with people required to use buckets when watering their gardens and washing their car. When announcing the restrictions, Berejiklian told reporters that we are in “uncharted territory” in regards to the rate at which our water levels have been declining. To give us the secrets behind the water restrictions, we talked to the University of Adelaide Professor Wayne Meyer.
