Sydney faces water restrictions due to low levels and high usage.

Greater Sydney is facing the possibility of water restrictions next year due to hot temperatures and the driest winter in 37 years. Water usage spiked by 17% over the October long weekend, and levels at Warragamba Dam, which supplies the majority of the city's drinking water, have dropped to 94% of capacity. Sydney Water is urging residents to conserve water and is launching a campaign to educate the public about the need to reduce water consumption.
