Southwest Airlines Maintenance Hangar at William P.Hobby International Airport

As a part of an expansion at the airport, underground water tight tanks were needed to capture contaminated runoff from the Southwest Airlines maintenance facility. The final storage system design included four (4), large 120-inch diameter DuroMaxx® SRPE tanks, each 98 LF and welded joints that provided the strength to handle the necessary loading requirements as well as the desired storage, providing 54,572 gallons of storage.
