Our general rule is 1 gallon to drink per person, per day, and an additional gallon per day for cooking, washing and brushing your teeth. So how much water to bring when camping, you ask? When camping in a car somewhere without water, you should plan to carry 2 gallons of water per person per day. When camping in nature, you should plan to carry one gallon of water per person per day. Let's see how much water is normally needed for a river on a camping day.
Fresh water is needed for cooking, drinking, cleaning the toilet, brushing your teeth, washing your hands, and bathing. You may need about 40 to 50 gallons of fresh water while dry camping. As we have already seen, for showers it could reach 35 gallons per day. For cooking, water use will vary depending on the number of people present in the camping caravan.
Or, you can bring your extra drinking water containers to fill at a park, so you don't have to interrupt the campsite or bring your motorhome. I have a little dinner before arriving at the camp, and when I arrive and set up the camp like a little more, and maybe I prepare a recovery drink. Even if there is access to drinking water, I always like to bring some of my own water from home to drink. I always say it depends on what you have for an RV, but I also let them know that drinking water is often the limiting factor.
If you somehow manage to bring in a lot of extra water, you can take a walk around the campsite and see if someone else forgot to bring enough or if they're running out. When I camp in the wild, the amount of water I carry to camp decreases dramatically, since I simply don't have the capacity to carry an additional 64 ounces of water when hiking.
