Queen of the Valley Medical Center in Napa, Calif., waters its grounds with the runoff condensation from its air-handling units, according to an article on the Outpatient Surgery website.
The facility has decreased its water usage by 40,000 gallons a year.
The recycled water is used to irrigate the Queen of the Valley's courtyard, helping it meet statewide mandatory water cuts.
Pipes gather the condensation from the hospital's HVAC system at a rate of 5 to 7 gallons an hour. This water is gathered into a small pool and piped into the main hospital's sprinklers.
