At a press conference yesterday, officials with Spurs Sports & Entertainment announced the changes, which came after a $190,000 grant from the San Antonio Water System.

The changes included the installation of high-efficiency toilets and 150 urinals in restrooms, aerating shower heads in the locker rooms and high-efficiency water fixtures throughout the arena. In addition, the arena's cooling tower will use recycled water. That alone will free up 9 million gallons of drinking water annually.

The arena is home to the San Antonio Spurs (NHL), the San Antonio Rampage (AHL) and the San Antonio Stock Show & Rodeo, as well as a full slate of other events.

The moves come after the Spurs Sports & Entertainment announced a shift last summer to the use of wind energy. On the slate, according to Spurs officials: More recycling.
