Updated and Advanced 3rd Edition of AWWA’s Manual 23 Provides Consensus Guidance for Designing and Installing PVC Pipe

Since AWWA approved and published its first plastic pipe standard, C900, 46 years ago, the use and acceptance of plastic pipe for potable water distribution/transmission pipe, reclaimed water pipe, wastewater force-mains, and irrigation pipe has grown steadily. AWWA’s PVC Pressure Pipe and Fittings Technical Committee worked diligently for more than five years to update Manual 23 (M23), PVC Pipe—Design and Installation. That effort was culminated with the 2020 publication of M23’s 3rd edition. AWWA M23 provides both general and technical information to aid in design, procurement, installation, and maintenance of PVC pipe and fittings. It serves as a consensus reference book for utilities and municipalities, consulting engineers, utility construction personnel, and installation contractors. The paper will examine the advancements over the last fifteen years which have been incorporated in the new, 3rd edition, together with lessons learned regarding the best practices for PVC and PVCO pipes and fittings. This paper will also highlight the information provided in new chapters that address trenchless installation and thrust restraint. These and other important design and installation updates will be summarily reviewed.
