Large Water Pump

The Large Water Tank is a storage building that holds water for beavers to use. It is an upgraded version of the small water tank and is designed for large settlements that need a much bigger reserve of water than the basic container can provide.

It costs 30 planks and 20 gears to build and requires 120 science points to unlock. The building must be placed on even ground, and it needs a path connected to it before it can be used.

Its main advantage is capacity: the Large Water Tank can store up to 300 units of water, which is 10 times the capacity of a small water tank. Since beavers consume about 2.1 water per day on average, a single Large Water Tank can support roughly 143 beavers for one day. This makes it especially useful as a buffer for dry periods, supply shortages, or any situation where a settlement needs a large amount of water on hand without constant refilling.
