A rubber dam is a flexible rubber bladder which is permanently anchored to a reinforced concrete foundation. Rubber dams are water controlling structures that can be inflated by air or water. When the bladder is deflated, impounded water is released and the bladder becomes virtually flat. Inflatable rubber dams are used in a wide variety of applications, including irrigation, water storage, power generation, flood prevention and control, erosion control, groundwater recharge, tidal barriers, navigation, and sewage treatment.

Pumped storage systems are based on the principle of pumping water from a low elevation reservoir to a high elevation reservoir using low-cost, off-peak electric power (when electricity prices are low).  The water is then released through turbines during periods of high electrical demand (when electricity prices are high), thereby increasing revenue.  Reversible pump-turbine assemblies act as both pump and turbine in these systems.
