Cincinatti/Northern Kentucky Airport SADF and stormwater expansion
|Market:||Municipal Infrastructure Rehabilitation|
Airports across the United States, including the Cincinnati/ Northern Kentucky International Airport, are under strict regulations to protect the environment. Clean water requirements assure airports manage levels of biochemical oxygen demand (BOD5) in their stormwater collection and management systems prior to offsite discharge. A major source of BOD5 for airports is propylene glycol, which is used in aircraft deicing fluid. A big challenge for airports is managing spent aircraft deicing fluid (SADF).
The Cincinnati/Northern Kentucky International Airport hired Gresham, Smith and Partners, located in Cincinnati, Ohio, to develop a solution for its stormwater and SADF collection and treatment system needs. Gresham, Smith and Partners, put together an engineering design that consisted of modifications to an existing pumping station, conveyance system and more capacity for the existing force main system. It also included the construction of a 6-million gallon in-ground storage facility. The force main improvements included 710 feet of 12-inch DR18 and 600 feet of 6-inch DR18 Fusible C-900® pipe. Fusible PVC® pipe was chosen for two important reasons: it is a gasketless, leak-free fusion-welded pipe system and Fusible PVC® pipe is a completely restrained pipe system.
