As rain continues in the county, the San Diego International Airport is doing its part to prevent pollution of the ocean and bay. When heavy rain comes, much of it runs off into bodies of water, adding to pollution problems. The airport recently installed one of the region’s largest storm water capture systems. The new system captures rain that falls on the Terminal 2 Parking Plaza, so that it can be recycled and put to good use. The water is diverted to the Central Utility Plant, where it is used in place of potable water in the airport’s cooling systems.
