The San Diego County Water Authority presented its 2019 Water Innovation & Efficiency Award to Marine Corps Air Station Miramar for significantly reducing its overall potable water use through a successful water conservation program and new infrastructure for distributing reclaimed water.
MCAS Miramar embarked on a water conservation program about a decade ago, and through a $6 million investment, MCAS Miramar decreased its potable water use by more than 40 percent since 2007. In 2015, the commanding officer formed a water conservation board tasked with reducing the base’s overall potable water use. The base now has a total of more than five miles of reclaimed water distribution systems, an increase of 47 percent from two years ago. This reclaimed water infrastructure as well as other water efficiency projects has allowed the base to save more than 100 million gallons of potable water each year.
Reclaimed water at the base is now being used for irrigation, construction-related activities, dual-plumbed buildings, street sweeping and soon for evaporative cooling. In addition, MCAS Miramar converted all aircraft and vehicle wash racks to isolated recirculated water systems, conserving 75 percent of the water used to wash essential equipment.
