Shower with a partner,(probably your wife/husband) and make sure you're standing inside a huge 'karai' while at it,then use that water to flash your loo or wash clothes.
Soak your clothes overnight first before washing,and use minimal soap/detergents while washing so that you dont have to use a lot of water to rinse the clothes.
