WebMany know that Polyvinyl Chloride (PVC) has a Manning’s n value of 0.009, but they conservatively use 0.012/0.013 based on Reinforced Concrete Pipe’s historical values after adjusting for sliming of the pipe wall and joints. Since PVC is highly resistant to sliming, this is considered as an overly conservative number, but we know it will work. WebClay pipe has been used in sewers for over 6,000 years, starting in Ephesus, in what is now Turkey. 100+ Years. NCPI has been a research institute for over 100-years.
