Case history of two large diameter sanitary sewer rehabilitation projects in Florida. The projects, located in Jacksonville and Tampa, involved the rehabilitation of deteriorated reinforced concrete pipe (RCP) by sliplining new centrifugally cast fiberglass pipe into the interior of the existing RCP. The projects are described from the planning stage; including an evaluation of replacement versus rehabilitation; the design stage, which specified a pipe product that would be a structural- and corrosion-resistant alternative to replacement and the construction stage, ensuring not only conformance to installation requirements but product compliance through laboratory testing.
