The State of Louisiana contracted with Waggoner Engineering for this FEMA Hazard Mitigation Grant Program project, which consisted of design, bidding, and construction services. The project replaced five existing pumps (two diesel and three electric) with five new 450 HP vertical mixed flow pumps, each with a design point of 40,000 gpm @ 36-ft TDH. Each pump has its own dedicated 42-inch pipeline discharge to the Mississippi River, so the total pumping capacity is 200,000 gpm (288 mgd). These pumps are responsible for pumping all stormwater from the 11,315-acre watershed.

A new 2,000 kW standby generator was furnished to provide backup power to the pumps during an electrical outage. A new CMU block Motor Control Center was designed, which contains the electrical gear (main breaker, automatic transfer switch, and motor controls). Civil/site design included ~35,500 SF of sheet pile installed along the banks of Bob’s Bayou, which feeds the pump station site.
