Two sections of corrugated pipe have been identified by the Water Pollution Control Department for repairs.
The first section, located at Partridge Avenue between South Pearl Street and South Hummel Drive is approximately 152 feet in length and requires repairs to the flow line and a separated joint. The pipe is 36 inches in diameter. The flow line has small pinholes that are becoming larger over time. The pipe has a separated joint that is causing a sink hole near the end of a neighborhood lake. Digging up and replacing the pipe is not really a viable option because one end of the pipe extends out under the lake.
The second section, located at Truman and Noland Road, is approximately 206 feet in length and runs along the north side of the Police Department building on Truman Road. This pipe, also 36 inches in diameter, has significant deterioration of the flow line and has a separated and dropped joint that is causing sink holes under the side walk. The area is heavily congested with other utilities and other improvements making it difficult and potentially costly to dig.
The best solution make repairs to both damaged sections is using a method called corrugated metal pipe using ultraviolet (UV)-cured spirally wound glass fiber-reinforced cured in place pipe (GFRCIPP).
