The District’s long-range Capital Improvement Plan includes rehabilitation of existing sewer lines throughout the District. This is done by placing a new liner inside of the existing underground sewer line without having to dig out it out and replace it. This process is called cured in place pipe (CIPP) lining. Each year specific sections of sewer line are chosen based on video inspections. This year the areas selected include downtown Goleta, the Nogal Bike Path near Modoc Road, Cathedral Oaks near Turnpike Road and in an easement off Via Los Padres Road. Together these improvements are referred to as the 2018 Pipeline Rehabilitation Project.
The Downtown Goleta portion of the project includes CIPP lining of approximately 8,400 LF of 8-inch and 6-inch sewer line. The Nogal Bike Path portion includes CIPP lining of approximately 1,600 LF of 8-inch sewer line. The Cathedral Oaks and Via Los Padres easement include 620 LF of 8-inch and 6-inch sewer line. There are 43 manholes in these areas which will be coated and various spot repairs will be made as part of this project. Bid requests have gone out and the Board of Directors is expected to approve the project by mid-July 2018.
This work is minimally disruptive to residents and may only require residents to not use their water lines for two to four hours while the liner hardens in the pipes. The process involves opening the manholes to insert the pipe liner, inflating it with air and curing it in place with steam. This trenchless process means that the road in front of the access manhole does not need to be disturbed (in most cases) and takes only a few hours to be completely readied for residential use. The project is part of the District’s Capital Improvement Plan which is an ongoing effort to maintain the sewer system in a cost-efficient manner while protecting the environment.
The work is set to begin in Mid-August and is expected to be completed by the end of January, 2019. See the maps below for specific streets to be impacted. For more information on the CIPP process, visit https://en.wikipedia.org/wiki/Cured-in-place_pipe.
