PROJECTS
US National Whitewater Center
Charlotte, NC
Completed in August, 2006, The US National Whitewater Center is the world’s largest and most complex re-circulating whitewater river. Perigon was selected to provide multi-discipline engineering and design for the pumping station, control tower and reinforced concrete of the water channels and ponds. This highly successful project holds 12 million gallons of water with seven 620 HP lift pumps moving more than 536,000 gallons of water per minute with an elevation change of 21 feet between the upper and lower ponds.
Perigon provided:
- Facility electrical power distribution planning and design, including power company technical coordination and owner representation.
- Complete Pump house and Control Tower design, including automation of pump systems, and water control gates to provide complete variability of conditions of the rapids up to Class IV. Also included was power, lighting, mechanical, and HVAC design.
- Structural design of the poured-in-place concrete lift station/pump house for the seven submersible pumps.
- Foundation design of filtration system equipment, inclined conveyor system, concrete retaining walls, and channel slabs of the concrete lined multi-channel system.

Ethylene Oxide Process Expansion
Adding new process equipment to a facility originally installed in the 1960s presented many challenges to the design and construction teams. Working closely with the owner and contractors, Perigon executed detail design documents for structural, electrical, instrumentation, and piping to facilitate the installation of this Ethylene Oxide process expansion at Old World Industries in 2006. The new process structure with caisson foundations had to be designed to fit within a very limited area with a variety of existing U/G obstacles. The new structure consists of two elevated floor levels supporting several large heat exchangers and vessels.
