Problem:
The Aircraft Rescue and Firefighting Facility at Henry E. Rohlsen International Airport in St. Croix needed a sustainable rainwater collection and reuse system to support critical life-safety operations like fire truck refilling and sanitary use.
The project faced several challenges: limited space for pumps and equipment, strict budget constraints, and the need for a low-maintenance, reliable system suitable for a remote tropical location.
Additionally, the system had to safely repurpose rainwater while meeting environmental standards and provide built-in redundancies to ensure continuous operation during emergencies.
Solution:
Stancor® P/S series submersible dewatering pumps were selected to deliver a compact, efficient, & low-maintenance solution.
Three P40C HV pumps with Teflon coating for corrosion resistance were manifolded on a guide rail system inside a 50,000-gallon underground cistern. These pumps move water 500 feet through a six-inch ductile iron pipeline to a remote truck-fill station.
The system includes built-in redundancies, alternating pump controls, flow verification, and a remote pedestal interface for operational ease. By providing compact, corrosion-resistant pumps capable of operating directly within the cistern, Stancor eliminated the need for a separate pump enclosure—reducing installation costs and simplifying long-term maintenance.
