Flow-Liner® Utilities Projects


Conduit Lining at the White House

Flow-Liner® Utilities was recommended for The White House project by one of the largest government contractors in the US. The Certified Flow-Liner® Utilities Installer had worked with the General Contractor just recently at a US Naval base relining underground conduits. The White House discovered water infiltration in their telecommunication conduits under the West Wing. CIP-Conduit® liner was efficiently installed by a Certified Installer, in one day- no demolition or excavation needed! More information found here.


Conduit Lining at IOWA Water Treatment Facility

The Cedar Rapids, Iowa Water Treatment Facility was built in 1929 with additions added in 1949 and 1969.  An ultra violet station was built in 2008 and is capable of disinfecting up to 40 million gallons of water per day.  Several 3" electrical conduits had water infiltrations issues. The lines all had several bends and were encased in concrete - excavation was not an option. A Flow-Liner® Certified Installer used the CIP-Conduit® Lining System to line twenty 3 inch conduits. The conduits were successfully lined in less than one week with no disruption to the treatment facility or its operations.
