08.04 How is the tank re-filled from a storage tank?

Base tanks are refilled in the same way as day tanks are re-filled with a couple of challenges: (a) limited room within the enclosure for mounting re-fill equipment, (b) shallow depth of tank may require special level sensors for refill control, and (c) shallow depth of tanks can make location of a properly sized overflow pipe difficult on the top sidewall of the tank.
