Rehabilitation of Multiple Water Lines

Underground Solutions was contracted by Southern Pipeline Construction to install approximately 2,000 linear feet of the patented Duraliner™ pipeline rehabilitation system on 11th Street, 12th Street, 13th Street, Magnolia Avenue and Ormsby Avenue in Louisville.

Five Underground Solutions personnel were on site to perform the installation and expansion of Duraliner™. Their efforts resulted in new pressure pipe installed with minimal disruptions. The installation of Duraliner™ also enabled Louisville Water to renew water lines in locations unsuited for standard dig and replace methods.

Existing cast iron pipe runs which were replaced with Duraliner™:

• 80 linear feet of 12" - 12th Street and Ormsby Avenue
• 570 linear feet of 8" - Ormsby Avenue between 11th and 12th Streets
• 610 linear feet of 6" - Ormsby Avenue between 13th and 14th Streets
• 540 linear feet of 6" - 11th Street between Magnolia Avenue and the railroad
• 60 linear feet of 6" - 9th Street and Magnolia Avenue
• 50 linear feet of 6" - 10th Street at Ormsby

Conclusion: Underground Solutions successfully installed Duraliner™ as specified by the project. In each case, the contractors with Southern Pipe and the Project Leader from Louisville Water were fully satisfied with project completion and workmanship.

Duraliner's chemical composition includes the butt-fusion capabilities of USGI's Fusible C900® product.After the McElroy fusion machine completes its work, the fusion bead is very clean.

The fusion bead can be trimmed off rapidly with simple power tools.

Duraliner™ starting stock is fed into faulty pipe, which is left in place.

Once the fused pipe has been fed in, the ends are capped in preparation for the expansion process.

The Mobile Expansion Vehicle (MEV) applies hot water and pressure to expand the Duraliner™ pipe, while sensors feed data to computers on the the MEV.

After the successful expansion, caps are removed, and pipe ends are trimmed off.
