City applies 3M SIPP 269 coating as part of EPA Aging Water Infrastructure Research Program
The city of Somerville, N.J., has applied the new 3M Scotchkote Spray In Place Pipe (SIPP) 269 coating to a portion of its drinking water pipeline, as part of the U.S. Environmental Protection Agency’s (EPA) Aging Water Infrastructure Research Program. The 3M coating is a polyurea-based liner that resurfaces existing pipes to minimize water loss throughout the system.
The EPA’s scientific and engineering research program evaluates promising technologies, such as 3M’s Scotchkote SIPP coating, that can reduce costs and improve the effectiveness of operation, maintenance and renewal of aging drinking water distribution systems. The coating aims to offer a sustainable, cost-effective alternative to traditional water-pipe rehabilitation methods, such as total replacement and cement-mortar lining, that disrupt water flow to homes and businesses. With a one-hour cure time, it minimizes the traditional side effects of pipe repairs, such as detours on city streets.
The field project in Somerville will give industry and government officials an opportunity to put the product through several challenges to create a quality assurance protocol. The installation was conducted in partnership with the city, and results will be evaluated by a team from Battelle, American Water and the EPA.
“As in many cities across the nation, portions of the water infrastructure in Somerville were showing signs of deterioration,” said Chad Carney, global marketing manager, 3M Water Infrastructure. “This field demonstration will rehabilitate an impacted section of Somerville’s pipeline, as well as provide performance and cost data that other cities can use to create new protocols and best practices for pipe rehabilitation.”
The SIPP 269 is ideally suited for pipe diameters of 4 to 12 in., and is approved to NSF/ANSI Standard 61.
