Vitrified Clay Pipe - Legendary Long Term Performance

Many sewer lines were installed during the last 150 years in the U. S. Industry estimates for total VCP installations are over 1Billion miles                            
The vast majority of these VCP lines are still hard at work, functioning to the design requirements of their time.

Comparison of Properties of Sewer Pipe Materials for Service Life  


Since the mid 1950's the requirement for treatment of effluent has become universal in the United States. Prior to this time it was acceptable to have joints in all types of sanitary sewers that were not water tight. These older lines sometimes were planned to have infiltration, providing for dilution of the effluent and less septic conditions.

A 1935 Metcalf and Eddy Engineering Company study showed that 98% of larger cities used dilution as a method for "treatment". This is no longer acceptable in the United States and most other countries.

New modern joints and manufacturing processes resulting in products such as Can Clay's CanOLok vitrified clay pipe exceeds the requirements of the ASTM C 828, "The Standard Method for Low-Pressure Air Testing of Vitrified Clay Pipe." This standard is performed on installed gravity lines and ensures water and air tight performance.
