Summary

Monolithic concrete pipe (also known as "Cast-in-Place Concrete Pipe" (CIPCP) or Cast-In-Place Pipe (CIPP)) is widely used in some regions for purposes such as storm, sewer, or irrigation pipelines.  The earliest use of CIPCP was in 1922 in the Turlock Irrigation District of California.  It is reported by The Sierra Group (Sierra, 1991) that there are over 15 million linear feet (4.6 million linear meters) of CIPCP under various applications.  Nevertheless, many irrigation engineers, especially outside the U.S., are unaware of CIPCP.  Monolithic concrete irrigation pipe is seldom mentioned in irrigation design literature.  This paper has been written to familiarize irrigation engineers with additional design options.  Cited references can be used to obtain technical and installation details.
