Leonard Engineering was selected to provide structural design services for the new sludge dewatering facilities constructed at the existing wastewater treatment plant located in Shelbyville, Kentucky. The improvements primarily included the addition of an open-air sludge holding tank structure and a 9,000 square-foot dewatering building. The sludge holding tank structure is specifically divided into two individual tanks, each measuring to be approximately 31 feet square by 16 feet deep. The tank in its entirety is constructed of reinforced concrete and extends approximately 14 feet below ground level.
The dewatering building itself is a 1-story facility that is composed of a dewatering room, an electrical room, two dumpster storage rooms, and a lower level pump room. The building includes a 5 ton monorail crane for removing and replacing the two centrifuges located within the dewatering room. Structurally, the building is built primarily of reinforced CMU walls and pre-engineered wood trusses for the roof. The floors and foundations are constructed of reinforced concrete with the floor of the lower pump room located almost 16 feet below the main floor level. In addition to the structural design, Leonard Engineering also provided Construction Administration services during the construction phase of the project.
