Liquid Storage can store 10,000 fluid (10 Buckets). Liquid Storage will connect to other Liquid Storage and share its fluid evenly. You can pick up a Liquid Storage including its fluid by Right Clicking on it while holding a Hammer, turning it into a portable Liquid Storage which can then be placed somewhere else. If destroyed the fluid in a Liquid Storage will be lost.

Note that fluid will not travel upwards when shared between Liquid Storage's. As a result you should fill them from the top and remove liquid from the bottom.
