CIPP Example 2

Message: CIPP can work well for slightly deformed pipes

---

Cured in place pipe was chosen as the rehabilitation alternative for this Powell County Dam for many reasons: 1) the dam was 45 feet high, so pipe replacement would have been a major effort; 2) although the host CMP pipe was beginning to deteriorate, it did not have visible holes; 3) the host CMP pipe was slightly deformed into an oblong shape, thus it was necessary to choose a “form fitting” liner like CIPP.
