Dulles Airport Dam

Slipping beneath the radar of most travelers, the Dulles Airport Dam quietly plays a crucial role. It’s a vital part of the airport’s infrastructure. The Dulles Airport Dam isn’t just a barrier against water. It’s a protector of the runways. Two earthen dams, including the Dulles Airport Dam, shield the airfield from potential flooding. They manage stormwater runoff. These dams ensure that even during heavy rains, like those from Hurricane Florence in 2018, the airport can continue to operate. Imagine the chaos if the south side of the airfield flooded. Flights would be grounded. Passengers would be stranded. The Dulles Airport Dam prevents this. It silently ensures the smooth flow of air travel. The larger of the two, the Taxiway Echo Dam, stretches over a quarter-mile. It dates back to 1952. This was when the Greater Pittsburgh International Airport first opened. The Dulles Airport Dam, smaller at about 50 feet thick, was built later in the 1980s. This was just before the present Pittsburgh International Airport opened in 1992. The maintenance of these dams is crucial. Crews regularly mow the grass covering them. This allows for inspections of any cracks. The outlet structures are also cleaned. Debris is removed to prevent clogging. This meticulous upkeep highlights the importance of the Dulles Airport Dam. It safeguards the airport and the passengers it serves. Beyond the dams, a network of retention ponds further controls water runoff. This comprehensive system demonstrates the airport’s commitment to managing its environmental impact. The Dulles Airport Dam may not be a glamorous landmark. However, its function is essential. It’s a testament to the importance of unseen infrastructure. It’s a silent guardian. It protects against flooding and ensures the airport remains operational.
