INSTALLATION OF SEKISUI SYSTEM INTO A RECTANGULAR CHANNEL
Abstract:The City of Los Angeles has approximately 6,000 miles of wastewater collection system. It primarily consists of small local sewers, primary sewer system, and the outfall system. Large diameter circular outfall sewers have been rehabilitated using the slip-lining method. The City has been working to develop biddable alternatives to rehabilitate the remainder of the outfall sewers. These are non-circular and present unique problems.
This paper describes installation of the Sewage Pipe Renewal (SPR) system developed by Sekisui Chemical Company of Japan into a non-circular channel. The SPR System uses winding technique to install continuous plastic strip that approximates the shape of the host channel. This represents the first installations of the SPR system in the United States.
