WebbThe most common SDR across the United States for gravity sewerage applications is SDR35. The minimum pipe stiffness for SDR35, per its specification, is 46 pii. Many agencies have used 46 pii—due to SDR35’s popularity—as the bar from which to compare all other pipe materials for sewer usage. Again, this can lead to false equivalence.
