Value Delivered

Our team provided general contracting services for the construction of a new pump station for United States Army Corps of Engineers (USACE). Station S-705 has a capacity of 100 cubic feet per second and pumps water into an L-31E Canal then flows through culverts into wetlands east of the L-31E Levee. 

The station features a 72-inch culvert with a slide gate for internal drainage, manatee-protective barriers, trash racks, and dewatering features, all complete with stoplogs. The side gate is operated by an electric motor actuator, and remote controls are in a stand-alone precast concrete building adjacent to the pump station. 

Client Objectives

The USACE designed the S-705 pump station to help with drainage along the L-31E Canal.
