Joanne Carroll, Senior Vice President of RS Lining Systems, the exclusive distributor of RS Technik CIPP technology in the Americas, made the announcement.

“This is a significant achievement. “Drinking water standards in the Americas are the strictest in the world, and we are extremely excited that we can finally offer this system to markets where the repair and renewal of aging water infrastructure is needed.” This latest certification follows RS BlueLine’s 2010 certification with German DVGW regulation W270 and the KTW for potable water that, like NSF, are the most rigorous standards in Europe.

With this NSF acceptance, RS BlueLine, using exclusive Dow® formulated epoxies, is now approved for the renewal of all municipal pressure pipe systems including drinking water mains, transmission lines and force mains.
