Project consisted of the design and construction of three primary drainage pump stations and outfall canal closure structures in the City of New Orleans. The combined pumps from all three site pump stations have a cumulative capacity of 24,3000 CFS (cubic feet per second) which forms the largest drainage stations in the world and can operate continuously and independently during hurricane events. Each of the Pump Stations is driven by large diesel generators and includes standby diesel generators. Pumps are vertical mixed flow configuration with single pump capacities as large as 1800 CFS and included installation of Controls, Electrical, HPU, Installation of New Bypass Sluice Gates, and Construction of the cumulative of a 650,000 Gallon Fuel Farm. M.R. Pittman served a joint venture partner in constructing permanent gated storm surge barriers and three brick façade pump stations adjacent to Lake Pontchartrain. The three stations have a pumping capacity of 2,700 CFS, 9,000 CFS, and 12,600 CFS. The pump stations are concrete substructures with steel/precast superstructures, an intake at EL. (-)39.0’, siphon type pumps driven by electric motors, and power from separate generator buildings. The project also includes control stations, surge gate structures, and associated flood protection in the form of concrete floodwalls and earthen levee tie-ins. The pumps move rainwater out of the drainage canals, around the gates, and into Lake Pontchartrain during a severe weather event and are equipped with stand-alone emergency power generated facilities with capabilities to allow operations independently of any local provided utility. Work also included an extensive test pile program, site grading and drainage, installation of surcharge material, temporary and permanent pile, demolition of existing structures, removal of existing pile, levees, cofferdam pile, dredging and deep well dewatering.
