If you're using your furnace then take water in a 5 gallon jug or two and and just pour it manually with a small container into sinks or to flush toilet, do dishes, wash hands, etc. You just need to conserve water a little more. Heat water on the stove if you need it hot. Your furnace will keep your underbelly warm enough to keep your waste tanks from freezing until you dump. You could also pour a little antifreeze down from time to time if its really cold. Then you just need to pour a little antifreeze back into your traps and you're all done again. Quicker than dewinterizing/ rewinterizing the water lines again with almost the same convenience of running water.
