Fiberglass pipe is used in many industries around the world for a myriad of applications. Durable, strong, and resistant to corrosion, it eliminates the need for interior linings, exterior coatings, and cathodic protection. Fiberglass pipe systems offer great design flexibility, and lightweight fiberglass pipe is available in a multitude of diameters.

AWWA Manual M45, Fiberglass Pipe Design, delivers both technical and general information for the design, specification, procurement, installation, history, materials, manufacturing, and understanding of both buried and aboveground fiberglass pipe and fitting systems. This fourth edition of the manual includes updates to trench and soil terminology, as well as changes to the definition of "compaction" to achieve uniformity among all piping materials.
