San Diego Plans to Use Drones, Monitors to Reduce Water Main Breaks, Sewer Spills

San Diego sharply reduced the number of water main breaks and sewer spills across the city last year, saving ratepayers money and helping many neighborhoods avoid significant disruptions.

City officials credited the decreases to ramped-up maintenance and replacement efforts on water mains, sewer lines and pipes, particularly those made of cast iron.

And to further reduce breaks and spills, San Diego officials say they will soon begin using drones and other monitoring devices to look for early warning signs of potential problems.
