Water is vital on the playa. You should plan on bringing 1.5 gallons per person, per day. This is enough for drinking and washing dishes, but more may be required for showers.
- 2.5 gallon dispenser-bottles are nice for easy filling of camel-baks and canteens
- 1 gallon jugs are awesome for drinking straight from the bottle
- 20 oz. bottles are not space efficient, as they take up more space going in AND out, however an empty 20 oz bottle has uses on the playa above and beyond waste. Specifically coverings for rebar, but there are infinitely more uses. Bringing a case of 24 for 4 people, maybe more, wouldn't be a bad idea.
