Chamberlain, SD — Busy Highway Stays open with Snap-Tite Rebah
South Dakota DOT Maintenance Crew Relines Old Culverts with Snap-Tite Pipe
Two corrugated metal pipe (CMP) culverts located under Highway 50 in Chamberlain, South Dakota were in danger of failing. One culvert was a 42-inch diameter CMP and the second culvert was a 30-inch diameter CMP. The culverts were located three-quarters of a mile apart from one another. The South Dakota Department of Transportation (DOT) regional office wanted to keep the lanes of traffic open during the repair, therefore digging and replacing the pipes was not an option.
Snap-Tite sales representative Guy Perna and Snap-Tite distributor Ross Eberle, P.E. from TrueNorth Steel in South Dakota, spoke with the SDDOT Mitchell Area District Office engineer, Tammy Williams, P.E., about using a trenchless method of relining the pipes as an alternative to digging and replacing the damaged culverts. The material chosen to reline the 42-inch CMP was 56 feet of 40-inch Snap-Tite pipe and 68 feet of 24-inch Snap-Tite pipe to reline the 30-inch CMP.
The high-density polyethylene (HDPE) pipe Snap-Tite culvert lining system has patented male/female machining at each end of the pipe, which allows the ends to be ‘snapped’ together, piece-by-piece, and pushed into the full length of an existing pipe. Snap-Tite also meets American Association of State Highway and Transportation Officials (AASHTO) Standard M326 for rehabilitating culverts.
