A potential addition:
Colonists have a 'hydration' need, that can be filled by drinking water or beer
Waterskins and, later on, canteens, to carry water around
Water can be directly drank or collected from lakes, but is unpurified, and can lead to all sorts of nasty diseases
Water purification technology, to filter water and make it safe
In the late game, pumps that can pull water from underground, pipes to bring it into the base, and automatic water bottle dispensers that fill bottles for colonists
Rainbarrels to slowly collect clean rainwater
