Abstract:

The cost of corrosion (both internal and external) in water distribution pipes and home plumbing in the U.S. has been estimated at about $700 million per year (EPA, 1984). More recent data compilations show about 240,000 water main breaks in the U.S. each year and approximately 4,000-5,000 miles of water mains replaced annually, and indicate that urgent investments in water infrastructure will remain huge – an estimated $1 trillion over the next 25 years (ASCE, 2013). These investment needs are largely caused by corrosion. The Tomahawk System is intended for pressure pipe renewal, mainly water distribution pipes (4 to 12 inches). It has been used to clean corroded water pipe for four years, and have now branched out into coating water pipes with the patented airborne coating process. It has been provided a bonded, economical corrosion polymeric barrier that improves C Factor and water quality (AWWA class I). The Tomahawk System has used for the City of Waterloo, Ontario (2015) and are now planning to use it to rehabilitate buried, corroded fire protection systems at DuPont plants in the US.
