Author Info City of Worcester, MAwww.worcesterma.govProduct Tags: PipePatch Quote We just made a nice repair of a hole we found in our sanitary pipe. It was a huge issue because 90% of the flow was going into the hole and entering our drain pipe. The infiltration was located in a section of pipe near a rail line, in the woods and down a steep hill. It would have been a big project to dig, most likely costing us a lot of money, time and man-power. By utilizing PipePatch's CIPP trenchless technology, the infiltration was quickly repaired in just a few hours.
