More than 14.4 million gallons of water was used in buildings on the Capitol campus in CY2011.
A new irrigation control system installed on the Capitol campus will reduce water use while maintaining the cultured grass starting in CY2012.
Turn the water off as you lather your hands with soap or while brushing your teeth.
