I don't think twice about drinking water straight from the tap, water quality here is excellent. It never has a mineral or chemical smell. The only trouble is that it's getting quite scarce with many years of low rainfall and we're on pretty tight restrictions, can't even wash your car at home, can't water lawns at any time and garden beds can only be watered twice a week in the early morning. Many new residential estates are using recycled water for outdoor use and toilet flushing, although it's definitely not suitable for drinking. They've just started work on the state's first desalination plant so the water quality may change when this comes online but at least I won't have to feel guilty about watering my plants. I could spend the dollars and install a rain water tank but if it doesn't rain then the thing's pretty useless anyway.
