A combination of metam sodium and dichlobenil kills the roots by penetrating and bursting cell walls on contact. Dichlobenil 50W is a unique herbicide crystalline compound that attaches itself to the existing organic matter and pipe joints, walls and cracks to immediately stop root intrusion and prevent new growth. A dense foam penetrates grease and root mass to ensure full chemical contact on all root and pipe surfaces. 800.841.1444, www.vaporooter.com

An effective chemical root control product, Vaporooter is guaranteed to kill roots on contact and prevent growth in sanitary sewer systems for a period of three years following application.

A small, high-tech Ohio business has developed technology that monitors temperature readings along a full segment of pipe during the curing of the CIPP (cured-in-place-pipe) lining process.

The procedure uses sensors strung by cable inside the pipe to be relined before the liner is inserted into the pipe, explains Jack Conte, president and chief executive officer of Zia Systems LLC.

“Quick and quiet,” is how John Riera, Water Resources manager for St. Petersburg, FL, describes a recent pipe bursting project using fused PVC piping in a residential area of his city. “Homeowners appreciated the speed and minimal disruption of the project,” he says. “We didn’t have a single complaint.”
