Section C work for the Okoboji Harbor Sewer Rehabilitation project is working with the manholes in the sub-division. This will be working internal grout of the public sewer manhole and then using a spray liner inside of the manholes. These products are used to limit ground water from getting into the sewer system. The grout and liner will also extend the lift of the manholes. This will be the last section of the project. It will be done in the spring of 2016 when the ground temperature has reached the proper temperature for the grout and liner to be installed.
