Sewer Slip-What??
Having run a television camera through some sewer main lines throughout town, the City Water and Sewer crew are now involved in fixing the major leaks they found during their search. The crew - along with a contract company - are slip lining the leaking sewer mains. A flexible, concrete-type material is fed into the sewer line via a sewer manhole. The material is then expanded to fit the pipe diameter, heated to cause it to harden, a machine re-opens the pipe openings through the slip lining to each service line and voila - the sewer leak is repaired without having to dig up the length of the sewer pipe. It is faster and less costly to repair sewer main lines in this manner. Although there are temporary street lane or alley closures, the process is much faster than having to dig up the pipe, install a new one and then refill and repair the torn up asphalt or concrete. Joe Doherty, Water & Sewer Superintendent, thanks everyone for their patience during the lane and alley closures. It's a dirty job but one that needs to be done!
