We have a 40L cap on our showers, in our tub that's just 4cm of water. The kids get capped at 40L as well (we can do this thanks to having one of those fancy hot water systems that turn the hot water off after a preset volume). Plus the kids do the whole bath water sharing thing to.
Run the dishwasher once a day, no hand washing of dishes.
If you can, hold off on doing any laundry or make sure you have a full load first.
If things get really desperate we do sponge baths, I don't think things are that bad yet.
I honestly don't see how we can pare our water usage back any further, I can't put disposables on my kids so the laundry is a non negotiable area.
