Client: City of Baton Rouge / Parish of East Baton Rouge Department of Public Works
Location: Baton Rouge, LA
Date of Completion: July 2013
As part of the massive City of Baton Rouge / Parish of East Baton Rouge Department of Public Works Sanitary Sewer Overflow (SSO) Control and Wastewater Facilities Program, Boh Bros. rehabilitated miles of sewer pipe using a process that is more cost effective and much less disruptive than traditional excavation and replacement, the Cured in Place Pipe (CIPP) method. The CIPP method involves a polyurethane-coated tube that is filled with polyester resin and a catalyst mixture into a pipe. Once the tube is inverted into an existing pipe, the resin fills all the cracks and voids. Heated water or steam is injected into the pipe, activating the catalyst and hardening the resin and essentially creating a new pipe within a pipe. During the SSO project, as a subcontractor to Grady Crawford Construction Company, Boh lined 125,500 feet of sewer pipe from May 2011 to June 2013. Boh has been installing CIPP for over 20 years in New Orleans, Baton Rouge, and elsewhere in Louisiana.
