October 23, 2018 - Tomahawk Cleans and Lines 100mm (4”) Service Pipe to Building at CNL, in Chalk River, Ontario

Pre-Project Condition:

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.

Project Details

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.
