Storage
Storage is a 
building category for structures that store Goods. There are three types of storage buildings: Warehouses, Piles and Tanks. Each type or category of good can be stored in a specific type of storage building. A storage building can only store a single type of good. You can change your selection at any time but before 
beavers start bringing the new resource, they will need to remove the old goods. Each storage building is open from at least one side, so it looks differently depending on the stored goods.
Builders can only collect 
Rubble piles if there is enough available storage for that good.
Hauling
By default, workers and 
haulers store their goods at the nearest available storage building. In addition, the storage buildings have a toggle to further customize the hauler's behavior.
Accept Goods
The storage simply accepts the selected good. This is the default setting.
Obtain
The colony’s haulers will do their best to actively fill the storage by picking up the selected good from other warehouses and transferring it here. This happens on top of the normal “Accept” behavior. This button is hidden if there are no Hauling Post in a district.
Supply
When set to “Supply”, it employs haulers to redistribute them to other warehouses, while continuing to accept new goods from any nearby producer. This mode has a secondary effect that affects the Distribution Post - storage set to supply will not be considered as part of the district's maximum storage capacity when the distribution post tries to balance quantities.
Empty
The storage no longer accepts goods. Its inventory will be cleared up and moved elsewhere by haulers or consumed.

Trivia
- You used to be able to store many different goods in a single warehouse. This caused interesting problems as one good would choke fill the entire warehouse (no maximum) and block production/delivery of other important goods.
- During the same time period, warehouses could also transfer power. They lost this ablity at the same time that walls were removed so you could more easily see what was being stored.
- Don't try to count the number of boxes visually displayed and compare it to the actual count. It rarely matches.
