The
2009-2010 Sewer Replacement project consists primarily of replacing manholes
and restoring sanitary sewer lines to near new condition through the use of
trenchless technology and open cut methods in portions of seven
neighborhoods (see map link by neighborhood below.) Eighty-five
manholes will be replaced or rehabilitated and more than 18,000 linear feet
of pipe will be repaired using trenchless cured-in-place pipe (CIPP). CIPP
rehabilitates the existing sewer line by inserting a resin coated cloth
liner with pressurized steam. The resin coated liner is then heated
with the steam to activate the resin. The hardened resin creates a pipe
inside the existing pipe. Additional information about CIPP is available by
following this link:
