The Project will generally include: The rehabilitation and lining of existing manholes throughout the City and the replacement of existing manholes with new concrete manholes. Existing manholes to be rehabilitated that do not have drop pipes or forcemains entering them will receive a cured-in-place liner. Existing manholes to be rehabilitated that cannot receive a cured-in-place liner will receive a geopolymer epoxy manhole liner. Work will likely include sewer bypass operations depending on the rehabilitation and/or replacement required. Removal of an existing sewer clean-out, followed by the installation of a new flow through concrete manhole in its place around an existing sanitary sewer main. Construction and installation of three (3) new precast concrete manholes around the existing sanitary sewer main within Barioni Boulevard and generally located between H Street and K Street. Isolation of the Cross Street lift station existing wetwells by means of plugging all pipe connections, followed by draining and cleaning of the existing wetwells, and protection of existing pumps and piping.
