This project contained a 100mm (4”) cast iron water service main into a building carrying both potable and fire water. The pipe was highly tuberculated causing flow rate and pressure concerns especially for fire-fighting purposes.

Location: Canadian Nuclear Laboratories, Chalk River, Ontario
Tomahawk Licensee: Envirologics Engineering Inc.
Pipe Details: The pipe was structurally sound. Pipe consisted of a horizontal buried pipe leading from the watermain service, under the building foundation, 90° of vertical bend, then up through the building’s interior floor
Pipe Size, Material: 100mm (4"), Cast Iron
Pipe Age: 45 years
Cleaning Technology: Tomahawk™ System by Envirologics
Lining Technology: Tomahawk airborne lining, BluKote™
Results: Water flow rate was restored to original design, improving potable and fire flows. The pipe’s useable life was extended by decades. Tomahawk’s insitu pipe rehab process eliminated the need to dig-up the building’s floor and foundation to replace pipe.
