  • Activity: Rainwater harvesting for toilet flushing and landscape irrigation.


BAE Systems installed a prototype rainwater harvesting system in 2015 at their 140-acre campus in Austin. It consists of a 2,500-gallon tank, pump, and filtration/disinfection equipment. Stored water is augmented by air handler condensate collection and is cross-connected to Austin Water municipal supply as a backup. It is used to provide water to toilets and urinals in one building on the campus. Expansion of the concept is planned across the 10-building complex. Also at the site are two 2,500-gallon tanks which provide water for irrigation of educational gardens and serve as a backup water source for water-chilling equipment.
