What does rehabilitation involve?

In 2022, engineers and technicians started work on cleaning, televising, and gathering profiles of the interceptor to inform engineering and design work. Through this analysis, they are recommending a variety of innovative methods to rehabilitate the structure. 

Gone are the days when miles of deep trenching – and incredible levels of disruption – were required to install and repair lines like these. Today, engineers and contractors anticipate being able to do much of the work below ground, accessing the structure from a dozen vertical access points. Through a process called slip lining and other modern techniques, the tunnel will serve Lakewood residents well for the next 100 years.
