There is a need for buried plastic non-pressure pipe
for movement of rainwater and sewage.
Key research programs recently initiated involve the utilization of ultra-wide band signals to see through pipe walls, developing and testing high-temperature cured-in-place-pipe (CIPP) resins, developing decision support systems for estimating construction costs and selecting appropriate technologies, the use of polymer sprays for pressure and non-pressure pipe
rehabilitation, developing geopolymer concretes and understanding machine-soil interactions during pipebursting.
ZF 0260 is said to offer more cost-effective stabilization of non-pressure pipe
at lower use levels.
The earliest recorded use of PVC non-pressure pipe
in the United States dates back to 1954 at Howard University in Washington, D.
