Workers with Insituform Technologies, LLC, have hit the streets in Hodgenville, as part of the city’s stormwater/sewer rehabilitation project.
Some streets have been blocked or limited to one lane while workers steam and clean lines. After the lines are cleared, a blue sealer is inserted to prevent stormwater from entering cracks in the pipes.
City Clerk MaDonna Hornback said the company has asked residents in the areas being rehabbed to not flush the toilet. It’s an effort to keep the “least amount of sewage” flowing through the pipes while they are working.
Little to no excavation is done with the pipe lining process. The liner is “cured” by the introduction of steam.
The liner extends the life of the pipe from 50 to 100 years, according to the company’s website.
The process was dubbed “insit u form,” which is Latin for “form in place,” when the patent was obtained in 1975.
Insituform is expected to be in the area another week or so.
