In 2013, Louisville Metropolitan Sewer District (LMSD) began constructing its Integrated Overflow Abatement Plan. The plan calls for decommissioning five small Water Quality Treatment Centers (WQTCs) in the Prospect area and conveying flows to a central treatment facility. Overall project completion is scheduled for December 2015.
The five WQTCs being decommissioned are Hunting Creek North, Hunting Creek South, Ken Carla, Shadow Wood, and Timberlake. The related pipeline projects required to eliminate the WQTCs are the River Road Interceptor, Harrods Creek Pumping Station, River Road Interceptor Phase 1A, and Harrods Creek Interceptor and Force Main (Phases 1, 2, and 3A). A Harrods Creek Force Main Phase 3B Project connects to the Harrods Creek Force Main Phase 3A Project. From that tie-in point, the force main will follow the Norton Commons Development, cross Brownsboro Road and Interstate 71, and eventually discharge into the regional Hite Creek WQTC.
|Pipeline Details and Project Summary|
|Project:||Harrods Creek FM Phase 3B|
|Pipe:||1,800 LF of 30-inch DR21 Fusible C-905®|
|Pressure Test:||150 psi|
|Installation:||Open-Cut / Jack & Bore|
|Engineer:||Jacobi Toombs & Lantz|
Engineering firm Jacobi Toombs & Lantz helped LMSD design the Harrods Creek Phase 3B Project with a total length of about 15,700 feet of 30-inch force main. Fusible PVC® pipe played an integral role in the construction of this project, especially in the sections of the alignment containing hilly terrain. LMSD specified 30-inch DR21 Fusible PVC® pipe for open-cut sections in the hilly, rough terrain in lieu of bell-joint restraints in order to eliminate the possibility of over-inserting the bell-and-spigot pipe.
MAC Construction was selected by LMSD for the Harrods Creek Phase 3B Project. MAC also used Fusible PVC® pipe as the carrier pipe in the jack & bore crossings under Interstate 71 and Brownsboro Road. Cory Placek, Project Manager for MAC Construction, commented: “It just made sense to use Fusible PVC® pipe for this project. The jack & bore sections allowed us to reduce the size of our steel casing pipe, which in turn saved us production time and money.” Placek added: “This project not only had hilly terrain, but it was isolated as well. Having the Fusible PVC® pipe strings pre-fused in the correct lengths made it quick and easy for us to drag the pipe to these isolated areas and place it into the trench.”
