Tank water only...so definitely no dishwasher for me...dishes aren't an issue really, there are only two of us, and grew up doing dishes. A quick rinse...if I've still water in the tub from the previous meal then it can be used for the rinse, then scrub with a soapy cloth...and rinse with the smallest amount that comes out of the top...we have solar power and a heat pump for hot water so the water is pretty hot. The rinse water gets saved for first rinses or used to soak crusty pans or used on plants outside....
