The City of Manhattan uses a sewer rehabilitation program to prevent groundwater from infiltrating the sewer system. Cured-in-place pipe (CIPP) is a sewer lining process that extends the useful life of sewer lines by installing a resin-impregnated tube into a deteriorated sewer. This process results in a seamless, jointless surface. It causes little disruption to customers because there is no digging involved.
In 2019, approximately 16,000 feet of 8-inch and 10-inch CIPP liner will be installed at various locations, including the Stag Hill and CiCo Park neighborhoods.
