In some areas of Vic if you build a new house you have to put in a rain water tank. If we owned our home we would have a couple. DH's parents have 4 tanks (they're in SA) and my grandparents have one as well. I've always grown up with them and miss my rain water!
We're saving water by doing just one load in the dishwasher per day (or two days if I can make it stretch). I have a "bucket" in the sink so any water spillage is captured and put on the garden. If I have to hand wsh dishes (heaven forbid!) I do them in this "bucket" and then that goes on the garden when cooled. DH is trying to get a suitable pipe tube thing to link to the washing machiene to water our garden with that water (but we have odd pipes for some reason so have to get a special piping?). I stick a container in my hand basin to catch water from when I clean my teeth, wash my face etc. I don't water my garden - it's mostly natives. I have some plants in pots but they get water into the tray underneath. The water from washing the floors goes on the moss that seems to be constantly growing on my driveway (I think the water is a little too caustic for my garden and need to get rid of the moss!). We wash our car once every 4 months if it's lucky! I use the eco save on my washing machine and dishwasher. I don't put a bucket in my shower with me because I'm afraid I would trip over it! My dog likes to "dig" in his water and tip over his water bowl so he has one of those clam things that I put water in. When I change it it gets tiped on the plants. Saves water because if he had a normal bowl he would go through about 10 a day min!

I also campaign at the fire brigade to do "dry training" sessions and promote dry fire fighting techniques. We also only train for competitions on recycled water tracks (water is 100% recycled so we're not wasting water).
