I forgot to mention the techniques we've been implementing. Mostly it's the If it's yellow, let it mellow method the Wife and I have been using, but also I sometimes wash my hands over a bucket and use that for flushing. It's not more than 1 liter every 1-3 days, but every bit counts.

I've also been fighting a leaking toilet seal, which it turns out can never be closed completely, but I've found out how to make it leak less. That toilet is the first thing on the replacement list for next year's renovation.

EDIT: Maybe I should add that not all showers happen at home (swimming pool for me and squash at the sports center for Wife and me). This doesn't effect the reduction in water usage, as this has been going on for years, but three short showers per week should be added to our average consumption.
