Last week I was a guest on an “inspection” trip of the Colorado River Aqueduct, the engineering marvel that delivers up to 1 billion gallons (3.8 billion liters) of water daily to Southern California from the Colorado River hundreds of miles to the east. Organized by the Metropolitan Water District (MWD) of Southern California, these inspections are a relic of an old piece of administrative code. Today they’ve become a well-choreographed public relations effort – right down to the framed MWD mission statement on the walls of the bedrooms provided to guests.
