3M introduces alternative to coating water pipelines
The new 3M Scotchkote Spray In Place Pipe 269 Coating for potable water pipeline infrastructure requires just a one-hour cure time and offers the ability for rapid, same-day return to water service to neighborhoods where pipelines are being rehabilitated. The Scotchkote coating remedies pipe corrosion, and in combination with a trenchless technology application process, restores pipe width and enhances water flow.

The unique polyurea blend formulation was first developed in 3M’s United Kingdom subsidiary, where similar products have successfully been used and proven for potable water infrastructure. “Coating water pipelines is crucial to public water systems to protect against leaching or migrating of contaminants into the drinking water supply,” said Gary Natwig, 3M marketing development manager for 3M Water Infrastructure. “3M Scotchkote Spray In Place Pipe 269 Coating is a sustainable cost-effective method of rehabilitating potable water pipe infrastructure.”

The company will be providing demonstrations and job training on this proprietary chemistry and trenchless application process and will establish pilots with municipalities.

Stantec to rehabilitate major Boston sewer line
Engineering firm Stantec has been chosen to design the rehabilitation of a major sewer tunnel running beneath a densely populated section of Boston, MA. The firm will be redesigning the West Roxbury Tunnel, a 12,500-foot-long, 84-inch-diameter rock tunnel that has become severely corroded over time. With depths of up to 220 feet and limited points of access, the project requires carefully planned logistics and marks the largest and most complex linear infrastructure rehabilitation project ever awarded to the firm.
