We have always camped in a pop up, so we naturally conserved water. If there are facilities close by, use that for showering and toileting. Otherwise, take a Navy shower and "if it's yellow, let it mellow, if it's brown, flush it down". We would often cook in an electric skillet, especially breakfast items. I then would add cold water and heat it in the pan, add dish soap, and use this to wash dishes. By the end, the skillet is pretty clean. Use another tub with a bit of fresh water for rinsing. No need to recirculate water - just dip it in and swish it around. Use paper products when possible. Conserving water is easy if you pay attention to what you are using it for.
