Saving Water: Efficiency and Reuse

The combination of water reuse and efficient plumbing fixtures means the Center for Urban Waters uses 46% less water than a conventional facility. This saves about 400,000 gallons per year, enough to fill more than 8,000 bathtubs.

Water storage tanks collect runoff from the roof and water rejected by the laboratory’s pure water system. Water collected in the tanks is used to flush toilets and irrigate plants. The green LED lights on the water tanks show the water level.
