Shakopee Lateral Sewer Pipe Rehabilitation


The City of Shakopee needed to rehabilitate their lateral sewer pipes to protect investments in new street pavement and boulevard restoration. To do it, they needed to rehabilitate privately owned lateral pipes without passing on expenses to property owners.


The project incorporated an innovative “blindshot” method, which uses robots to shoot ASTM-approved liners into the existing lateral sewer pipes, by entering from manholes. The liner is then cured in place. The “blindshot” method does not require any excavation in the street or on residential property, which adds considerable expense for restoration costs. To reduce expense, a competitive bidding process was developed putting contractors head-to-head, ultimately saving the City money.
