To replace existing Pump Stations that are 40 years old with new pumps and upgraded electrical power.
High water on an airfield always presents a problem, but in the aftermath of superstorm Sandy, the Port Authority of New York & New Jersey stepped up the planned replacement of Pump Station Nos. 4 and 6, which drain LaGuardia’s two runways.
GA Fleet worked with Flygt on the procurement of eight Flygt 300-hp, 33,000-gallon-per-minute, propeller-style electrical submersible pumps. The two runway Pump Stations were upgraded to be 5-kv substations situated in less vulnerable locations. The axial flow pumps are ideally suited for the airside upgrade, where they will move large volumes of water at low heads (25 ft).
In addition to the engineering developed in collaboration with Flygt, G.A. Fleet supplied the interface for the pump intakes, controls and other components to facilitate the replacement by the installation contractor.
G.A. Fleet sized and matched the replacement pumps to function as an engineered system that improves the airport’s storm water control, flexibility and operational efficiency.
