A comprehensive update to the American Water Works Association (AWWA) C906 standard may affect users of HDPE piping.

The C906-15 update includes enhanced performance high-density polyethylene (HDPE) resins — PE4710 — that improve the durability and reliability of HDPE pressure pipe used in industrial and municipal water and wastewater systems.

Updates in C906-15 include:

  • Zero-leakage allowance for improved water supply and water conservation.
  • Improved durability of resin.
  • Higher pressure class (up to 335 psi).
  • Larger internal diameter and increased flow capacity.
  • Enhanced surge capacity and fatigue life.
  • Covers additional sizes (up to 65” in diameter).
