Gateway Arch
Condensate Pumping Systems

The Gateway Arch has many pumping systems that create a pleasant environment for all the people who visit and work in this national monument. These pumping systems also protect the many exhibits within the Gateway Arch. Closely controlled operating temperatures and humidity are important.

The Arch is more than 40 years old. These photos depict several condensate pumping systems that must be periodically maintained to keep the Gateway Arch functioning properly.
