The cleaning of a pipeline is performed for a number of reasons including pipe blockages due to roots, grease and sand buildup. Pipes are cleaned to increase available capacity taken up by debris and other materials, as well as to prepare a pipe for the installation of a renewal technology. Most renewal technologies require that the host pipe be totally free of any debris and accumulation before the new product is installed. Cleaning devices will vary depending on the type and amount of debris in the pipe. Most equipment uses a combination of mechanical equipment and water pressure. NASSCO has published a Jetter Code of Practice (available in English and Spanish) which reviews different devices and nozzles that are typically used to clean pipes using high pressure water. This manual is available from NASSCO at www.nassco.org
Why Clean:
The RehabZone would not be possible without the generous contributions of industry leaders, companies and organizations that share UIC’s vision to set standards for the assessment, maintenance and rehabilitation of underground infrastructure and to assure the continued acceptance and growth of trenchless technologies.
