SFPUC Enlists McGovern McDonald Engineers to Perform Special Inspection of Lining of Digester at Oceanside Plant

When the SFPUC found themselves in urgent need of inspection services for the lining of their digesters at the Oceanside Water Pollution Control Plant, they enlisted the help of McGovern McDonald Engineers. MME quickly mobilized their team, equipped with a drone and additional special camera equipment that could inspect inside the dark and corrosive environment of the digesters.

MME executed an internal inspection of Digester 3, which included High Definition videos of 360 degrees inside the tank at several elevations and up to 40:1 camera zoom, providing the plant staff with the information they needed to make decisions about repairing and replacing the failing lining. MME also performed an aerial inspection of all four digesters using their drone.
