Edmonston Pumping Plant

It is the most powerful water lifting system in the world, not considering pumped-storage hydroelectricity stations.

At full capacity, the pumps can fling nearly 2 million gallons per minute up over the Tehachapis.

This prevents tunnel damage when the valves to the pumps are suddenly open or closed.

Near the top of the lift there are valves which can close the discharge lines to prevent backflow into the pumping plant below in event of a rupture.
