TRANSCRIPT
Our municipal water pipes are reaching the end of their useable lives
Cities throughout North America have 100s of KM’s of aging, congested pipes
Example of tuberculation and bitumen found in potable water pipes
Why does this matter?
• Service outages • Damage to infrastructure • Poor water quality • Reduced fire flows • Increased energy costs to
pump water through pipes
Good News: Trenchless coatings and
linings offer cost-effective renewal solutions
They are required to keep the pipe strong, healthy and corrosion
free!
Current Cleaning Methods – AWWA M28
Challenges:
• Foul a lot of clean water and generate wet waste
• Current methods can damage services connections,
joints and pipe wall due to high forces involved
• May requiring multiple passes to achieve results
• Linings such as coal tar or bitumen are not fully
removed
• Pipe may be cleaned but not fully prepared for liner
bond
8
• Prevent liner leaks and structural failures • Clean – reduces stress concentration points in
liner • Prepared – high degree of surface cleanliness
and dryness to ensure liner bond to pipe wall and service connections
Left – cleaned pipe
Right – cleaned and prepared, ready for liner bond
Clean and Prepared Pipe
Tomahawk™ System Innovative Pipeline Renewal
In-ground watermain up to 450’ long
Standard Vacuum Truck
Patented and patent-pending Tomahawk™ System
Click here to view a Tomahawk process overview video
Debris Capture
• The Tomahawk process is closed, Tomahawk unit connected to one end of the pipe, vac truck at the other
• Eliminates the visual impact of waste being released from watermain during cleaning operations, especially to local customers and residents!
• Dust, debris and cleaning stone are captured by vac truck maintaining a clean and safe worksite
• Ease of disposal
• After initial cleaning, the patent-pending Tomahawk
Scout™ is instantly deployed without connection changeover to help prepare the pipe
• Airstream driven, integrated
CCTV camera and abrasive
deflector
Pipe Preparation Concurrent Cleaning, Drying and Inspection
Pipe Preparation Using Tomahawk Scout™
③ Vaculate trapped water or debris from service connections
② Draw (vaculate) pooled water and debris from joints and crevices
① Target clean along pipe, at joints, around service connections for improved liner bond
Fast Drying of Service Connection - Tomahawk Scout™
① Vaculating trapped water from a service connection
② Dry until ready for lining
• Time from ① to ② = 2 minutes • Check out vaculation videos at the link below,
http://www.envirologics.ca/tomahawk-scout
• Various calibers • Our stone is clean and dried
at high temperature • Verified bacteria free
Abrasive - Stone
• Amount of stone and debris after cleaning 6 pipe sections
• 25 to 35% of average vac truck capacity?
• Truck can stay onsite all week without having to take waste to treatment site
Dry Waste
Same Day Return to Service
Tomahawk
No bypass piping installed Small 4’ x 8’ pipe access pits Minimal surface disruption

street during a same day return to service project
Advantage – Same Day Return to Service
No costly service bypass piping save up to 30% of project cost Minimal surface disruption, short duration reduces inconvenience to residents Reduction in project timeline no bypass piping setup, disinfection, approval, operation and teardown
Opportunity: Asbestos Cement Pipe Cleaning and Preparation
Before Cleaning: Bio film, small amounts of debris, loose wall material and moisture in pipe wall are visible
After Cleaning: Minimal moisture remains only
Pipe requires lining after cleaning and preparation
• Two pipe sections cleaned in one day under same day return to service conditions
• 100mm (4”) to 200mm (8”) pipe, increasing to 300mm (12”) in 2015
• Clean up to 135m (450 feet) • Up to 40% tuberculation • 22.5° elbows
