In October 2008 Underground Solutions, Inc. (UGSI) contracted with Mr. Pipe Tech LLC of Miles City, MT to provide Fusible C-900® pipe in support of a waterline renewal project at Ellsworth AFB. Fusible PVC® pipe was selected to replace a deteriorated Cast Iron (CI) and Asbestos Cement (AC) waterline beneath the taxiway via pipe bursting. Mr. Pipe Tech, a UGSI-qualified fusion contractor, performed fusion services as a subcontractor to Rapid City contractors: Iron Horse Excavating and Dean Kurtz Construction.
Critical to the AFB for both potable water and fire hydrant supply, the existing 8" CI and AC line was nearing the end of its useful life. Pipe bursting was selected to minimize the cost of cutting and replacing expensive two-foot thick, specialized concrete and to eliminate disruption to take-off and landing schedules.
Ferber Engineering selected Fusible PVC® pipe because of its: 1) compatibility with pipe bursting, 2) size-on-size pipe replacement to minimize soil disruption while maintaining inner diameter and flow, 3) gasket-less pipe system to minimize entry points for hydrocarbon permeation, and 4) superior material resistance to groundwater hydrocarbon permeation and contamination as compared to HDPE.
The project was completed in November of 2008. Jake Ankele, of Iron Horse, stated: "So far from what I have seen, Fusible PVC® pipe is a very good product and we are going to use it on some additional work on the base."
Dan Ferber of Ferber Engineering commented: "This was our first experience with Fusible PVC® pipe. Iron Horse Excavating, UGSI and Mr. Pipe Tech did an excellent job of installing the new main with minimal disruption to the normal operations at Ellsworth Air Force Base. We expected a professional job, but were especially surprised by the speed of installation."
