Estimated Material Service Life of Drainage Pipes - CCPPA

Since service life for thermoplastic pipe is still to be fully experienced, one would think the use of a “projected” EMSL in a changing environment could be risky. At the least, check 100% of installed pipes until field experience can support these projected values. For concrete pipe, the industry has addressed the impacts of the environment.
