The 3,150 LF Turnagain Interceptor Sewer Project in Anchorage included rehabilitation of an existing corroded 4-foot diameter concrete pipe using sliplining technology. To save money, the sliplining work was completed in a live flow condition while 11 million gallons per day was running through the host pipe. Construction on the $1.7 million project was completed in 2011.
