I started recording my our water meter regularly in late 2008 and during the first year we averaged about 280 liters (74 US gallons) per day, now our daily usage (averaged over the last year) is closer to 160 liters (42 US gal). Three adults, one big dog (drinks ~1 liter per day), and as of April one infant. Because of the latter our usage may go up a bit.
I've replaced one toilet with a newer model, but most of our savings came from reusing grey water and from using rain water (first one 220-liter barrel, then 3, now 5 since last month), which we use 7-8 months per year for garden watering, car washing and sometimes flushing .
