Description of Proposal


The proposed project increases the reliability of an existing 16-inch 90-year-old drinking water feeder main by installing a cured-in-place pipe (CIPP) inside 242 feet of the main and replacement of two small sections of other downstream pipe. Because this main conveys water to significant areas of the community, the increased reliability will prevent the high level of disruption that would result during failure events and maintenance shutdowns affecting this main.


CIPP is a trenchless rehabilitation method that installs a jointless, seamless, pipe-within-a-pipe to repair or rehabilitate existing pipelines. Access for installing the CIPP in the 242 feet of pipe would require two access pits to be excavated.  Each pit would be 6 feet wide by 10 feet long by 10 feet deep. One access pit would be excavated in the Broadmoor Golf Club’s golf course; the other would be excavated in the street right-of-way for Parkside Drive East.  For the other two pipe sections, access trenches would be excavated in the street right-of-way at the intersection of Shenandoah Drive East and Windermere Drive East. This work would also require construction of temporary access road across and along two fairways of the Broadmoor Golf Club’s golf course.
