LWC Chapeze Booster Pump Station
- Project Owner: Louisville Water Company
- Architect: Studio Kremer
- Contractor: MAC Construction
- Process Engineer: HDR
- Completion Date: Summer 2016
- Location: Bullitt County, KY
- Cost: $2.5 million
The Chapeze Booster Pump Station (BPS) is located in Bullitt County near Interstate 65 and Chapeze Lane, which is approximately 1 mile north of the I-65 and KY 245 (Clermont Road) Interchange. The Chapeze BPS was introduced to specifically improve the Louisville Water Company’s (LWC) existing 760 pressure zone which serves Bullitt County. The Chapeze BPS, in conjunction with the newly installed 1MG capacity elevated water storage tank, located approximately 1.2 miles south of the pump station, allows LWC to increase flow and pressure along the I-65 and Preston Highway corridor to existing and future interconnects with wholesale customers in Bullitt and Hardin County. The pump station includes a total of five pumps with a connected capacity of 14 MGD. It will specifically pull suction from the 690 pressure zone, which includes multiple tanks as well as the Minor Lane BPS, and will discharge to the new elevated tank at I-65 and KY 245 as well as the 760 pressure zone. For this project, Leonard Engineering was specifically tasked with providing both structural and architectural services during the final design of the booster pump station. To aid with the development of architectural designs and details, Leonard Engineering teamed with Studio Kremer Architects.
The pump station itself is a 1-story, 3,200 square-foot facility that is composed of a pump room, electrical room, and a storage room. The pump station includes a 2 ton bridge crane, located within the pump room, for removing and replacing pumps and piping. The pump room also includes two 4 foot wide by approximately 7 foot deep trenches for housing the suction and discharge piping below the floor level. Furthermore, the building is primarily supported on a drilled shaft foundation system that extends to underlying bedrock. The decision was made during the design phase to support the building on deep foundations to eliminate differential settlement and the potential for damages to process piping as a result of settlement. The floor of the pump station is composed of a concrete structural slab and grade beam system, which are supported by the drilled shafts. The above grade portion of the pump station is primarily constructed of reinforced CMU walls, pre-engineered light-gauge trusses, and a metal deck roof diaphragm. In addition to the structural design, Leonard Engineering also provided Construction Administration services, as well as Special Inspection services, during construction of the pump station.
