We worked as a subcontractor for Insituform in Coon Rapids, MN to help rehabilitate the existing sanitary sewer interceptor. The project consisted of MH rehabilitation, new forcemain installation, tunneling and installing 4 separate temporary conveyance systems. The 72″ diameter steel casing tunnel for a new gravity sewer consisted of 200 LF in length and working closely with CenterPoint Energy to tunnel under two high pressure gas mains that were pressurized over 500 psi!
