Building Products, a subsidiary of MCP Industries, has been manufacturing and supplying Vitrified Clay Pipe (VCP) to the city of Phoenix Arizona and surrounding jurisdictions since 1973.  The desert areas of Phoenix, along with adjoining areas of Southern California, understand that intense desert heat and hydrogen sulphide gases generated in gravity flow sewers create havoc to the life span of sanitary sewers.

50 year life expectancy pipe (PVC)
is unacceptable versus the 100 year+
proven life cycle record of clay pipe VCP). 
For this reason, Building Products LLC
has grown to be the largest
manufacturer of Vitrified
Clay Pipe in the entire
South Western United States.
