Understanding AWWA M55: PE Pipe Design and Installation The American Water Works Association (AWWA) M55 manual, titled PE Pipe—Design and Installation , is the definitive resource for water professionals utilizing polyethylene (PE) piping systems. As municipalities and utility companies increasingly transition away from traditional rigid materials like iron and concrete, understanding the engineering principles behind flexible PE piping becomes critical.

The industry standard has shifted heavily towards high-performance PE4710, which provides better resistance to slow crack growth and higher pressure capacity.
Unlike rigid pipes, PE pipe is viscoelastic, meaning it can absorb significant pressure surges. AWWA M55 outlines how to calculate the Working Pressure Rating (WPR) and accounts for both recurring surges (e.g., normal pump cycling) and occasional surges (e.g., sudden valve closures). 2.

Hydrostatic testing parameters require filling the line with water, venting all air, and bringing the system up to 1.5 times the system design pressure at the lowest point. The manual guides operators on how to account for the initial expansion of flexible PE material during the test phase. Repair Methods
