Pratt & Whitney Rocketdyne, the nation's number one rocket engine provider, has saved an impressive amount of both water and energy. The company's seven large cooling towers, which previously required thousands of gallons of water to flush out mineral deposits, were upgraded with water softeners to eliminate the need to dump and refill the tanks. In the company buildings, Pratt & Whitney installed waterless urinals, replacing over 80 units. The company also installed weather-based controls on their landscaping to reduce unnecessary sprinkler use. Together, these steps have saved over 8 million gallons of water annually. Pratt & Whitney has also taken extensive steps to save energy, installing a variety of retrofits which have saved approximately 841,300 kWh of electricity and reduced carbon emissions by an estimated 3,188,712 pounds each year.
