Trumbull installed two 450hp, and four 800hp pumps, as well as, 1,200 LF of 24″ diameter glass lined ductile iron discharge pipe, in a previously constructed shaft. Coupled with a state of the art operating system, the pumps dewater the tunnel after each overflow event, sending 35M gallons a day of sewage to a wastewater treatment plant.
Trumbull also constructed a pump electrical building, bridge crane, and the Scioto-Main Relief Structure, which can be used as bypass.
