Airport Water Management

How Rainwater is Reused at San Diego Airport

Water stewardship means using less water, wasting less water and protecting water quality. At San Diego Airport (SAN), all are vitally important. The airport is uniquely situated in a borderline arid climate (up to 80% of all the County’s water is imported from points north and east) and on the edge of San Diego Bay.

A new Parking Plaza slated to open in late Spring 2018 will do all three at the same time. Besides enhancing customer service and meeting growing demand for close-in parking, the Parking Plaza will capture rain that falls on the 7.6-acre structure (1 acre is about 4050 square meters), routing it into a below-ground storage system with a capacity of nearly 100,000 gallons (1 gallon is about 4 liters). Instead of becoming stormwater runoff, potentially impacting San Diego Bay, the collected rainwater will be used by the immediately adjacent central utility plant that houses the heating, ventilation and air-conditioning (HVAC) system.
