As the baseball regular season draws to a close we revisit a post from the beginning of the 2010 schedule. For the second year in a row, a new baseball stadium earned LEED (Leadership in Energy and Environmental Design) certification. Back in the spring, Target Field, home to the Minnesota Twins, used a variety of measures to attain LEED silver. In 2009, the Washington Nationals earned the general LEED certification.
Pentair installed “a custom-designed Rain Water Recycle System” at the ballpark. The system, the first of its kind according to Pentair, follows these three steps, Capture, Conserve, Reuse. The first step involves a 7 acre rainwater collection system. This water is stored deep underground in a cistern below the field. Next, the water goes through a filtration process before it is ready to reuse for field irrigation and stadium washing. Watch the company’s brief video on the partnership with the ballpark.
The net effect of the cistern and rainwater capture system will be to reduce water consumption by 2,000,000 gallons annually. In addition, Pentair is working with the Twins to increase awareness of global water scarcity, which it says affects 1 in 3 people.
