The Twins and one of their newest sponsors, Minneapolis-based Pentair Inc., said that the team's new ballpark in downtown Minneapolis will be the first major sports facility anywhere to be irrigated and washed down with recycled rain water. The recycling system, designed and installed by Pentair, will collect water from Target Field's seven acres and drain it into a 100,000-gallon cistern buried below the field. There the water will be disinfected and treated. Officials estimate the system will save the city of Minneapolis more than 2 million gallons of water annually, about half of what the ballpark will need. Twins officials said the recycling system sets "a new environmental standard in sports," and Pentair officials said they hoped it would raise awareness of the issues of water quality and scarcity.
