Character water consumpsion as it is now makes no sense. Humans are not dripfed water 24/7, instead the human body can "store" water. Mimic this by having 2 bars for water, one for the caracters "body storage" and one for a water bottle. The water bottle is used firsr untill empty than body storage is used. Drinking from sinks fills only the body storage, bottles are filled by wells or some other way insinde player bases, maybe add a water bottle filler to the food dispenser. Free water hoses should not refill water.
