Do they really store drinking water? Are they used to store water for fighting fires? It seems impractical to store basically a drum of water hundreds of feet in the air.
In: Engineering
It stores water for any purpose, and it’s tall because that’s an easy way to maintain pressure without running the pumps continuously. The demand for water isn’t constant, and electricity prices aren’t constant. You want to pump water into the tower when electricity prices are low, 3AM for example, and then you can use it when demand exceeds your pumping capacity, or energy prices are high.
