Abstract: The results of an extensive investigation to evaluate the in-service condition and future serviceability of an existing lake water make-up pipeline are briefly described herein. The pipeline consisted of 30-in. (762-mm) diameter prestressed concrete lined cylinder pipe with a length of approximately 5 miles (8047-m). During the 6-year period since installation, the pipeline had experienced five separate ruptures. As a result of the ruptures, an in-depth investigation was performed by the authors.
