About The National Clay Pipe Institute

Clay pipe has been used as a drainage and sewer pipe for over 4,000 thousands of years.  Here in the United States, the first system in Washington DC was installed in 1815.  In those early years, there was little information about the actual performance of buried pipelines, even fewer standards relating to the installation of a gravity sewer system and no minimum standards for manufacturers.  As more municipalities began to install sewerage systems for the protection of the resident populations, more attention was directed to the characteristics and properties of the materials, design standards and installation practices used to build these systems.

The National Clay Pipe Institute, established in 1944 by clay pipe manufacturers, is the single center for the research and development of clay pipe technology. As a result of this focus and decades of research and development, we have become the authority when it comes to Vitrified Clay Pipe.  We are available to provide assistance in design, training and evaluation of systems.  Forensic analysis can also be performed if necessary.

One of the earliest industries to work with ASTM , clay pipe manufacturers were instrumental in establishing production and installation standards more than 100-years ago.  This rich history provides an unmatched level of experience that we bring to wastewater collection challenges.

As an organization we are responsible for the development of leak free, factory applied compression joints and the air pressure test to verify the performance of those joints.  We defined and characterized specific methods and practices for placing pipe to insure the longest service life of any available material.

In the twenty-first century, The National Clay Pipe Institute is an unsurpassed technical resource offering educational seminars on a variety of subjects (with CEUs available depending on local regulations).  We continue our strong tradition of scholarly research by partnering with universities and municipalities in field research projects designed to answer address specific concerns.
