A couple of years back, in Portland, Oregon, a main sewage pipe failed, creating quite a stink — the kind of stink caused by 15,000 gallons of leaking raw sewage. The contractor had an idea that would replace the proposed HDPE inside a 6-foot diameter steel pipe. For the first time in the U.S., Flowtite® was used for a microtunneling project. A single pipe instead of two, and the new one wouldn't corrode like a steel pipe. Also, the owners wouldn’t have to pay for expensive liners or other anti-corrosion measures down the road.
