Refiners and petrochemical producers are faced with a number of issues related to aging infrastructure in their processing facilities. Many of these facilities were initially constructed in the 1960s or earlier and have a large number of plant-wide utilities, general facilities and underground piping systems that are at least 30 years old. Many underground piping systems are approaching the end of their useful life which can be extended only by substantial reconstruction or rehabilitation. This paper will focus on the rehabilitation of underground effluent piping systems such as process sewers, contaminated storm sewers, low-pressure effluent force mains and sanitary sewers. While the technology that will be discussed is also used to rehabilitate water lines in raw, treated and cooling water service, the environmental issues involved with these effluent piping systems justify this focus. A number of options for reconstruction or rehabilitation of process effluent piping will be reviewed briefly. The rehabilitation method that will be discussed in detail is the trenchless or so-called no dig technique using a Cured-In-Place Pipe (CIPP). This technology was originally developed in the early 1970s for rehabilitating municipal sewer lines and has been adapted or further developed for industrial use. Since then, the technology has been used to rehabilitate more than 22 million feet of buried pipelines, including more than 200,000 feet of industrial effluent lines in the past three years.
