Pangborn Memorial Airport is a regional airport located within Douglas County, Washington. Owned by the Chelan Douglas Regional Port Authority, the airport is used primarily for general aviation and is served by one airport that offers in-state services.

In 2021, a grant was awarded to the Chelan and Douglas Counties to reconstruct the airport’s apron and apron lighting section, increasing the apron space from 95,000 SF to 160,000 SF. As part of these improvements, Chelan Douglas Regional Port Authority decided to move a 576 SF equipment storage building from one end of the apron (ramp where planes park) to the other end, improving the space and expanding portions of the area where passengers disembark.

A new glycol containment tank was included within the improvement plans to handle glycol runoff on the newly constructed apron. Originally a precast vault was specified. Given the inherent cost and installation challenges, the winning bidder, Hurst Construction, evaluated alternative solutions. Ultimately, a DuroMaxx® steel reinforced polyethylene (SRPE) glycol containment tank was selected due to its watertight, welded-coupler joints and lightweight design for an efficient and cost-effective solution.

DuroMaxx® SRPE met all the project design requirements including the large storage capacity required, watertight joints, and the ability to effectively store the glycol chemicals. Additionally, DuroMaxx meets Buy American requirements and is approved by the FAA and has been used in various applications for multiple commercial and military airports around the U.S. adhering to the requirements of the federally funded project. The final design included a DuroMaxx® SRPE glycol containment system of 174’ of 120-inch diameter. The total storage for this system is 88,600 gallons.
