October 26, 2018 - Tomahawk Cleans and Lines Watermains in Sherbrooke, Quebec
This project contained 500m of 150mm (6”) ductile iron pipe on two residential streets. The pipes were highly tuberculated resulting in very low pressure, flow rates and chlorine residuals.

Location: Rues Blanchard and Brouillette, Sherbrooke, Quebec
Tomahawk Licensee: Logistique Saint-Laurent Inc., Gilbert Group, Chicoutimi, QC
Pipe Size, Material: 150mm (6"), ductile iron
Total Length: 500m with 49 residential service connections
Pipe Age: Approximately 50 years
Cleaning Technology: Tomahawk™ System
Lining Technology: Tomahawk airborne lining, BluKote™
Results: The residents on these streets are now enjoying renewed water flow rates and pressure. The C-factor improved from a low of 15 to a high of 111, representing a 740% improvement. Chlorine residuals also improved resulting in higher quality drinking water. The pipe’s useable life has been extended by decades.
