AWWA C303 pipe has been known as Pretensioned Concrete Cylinder Pipe and Bar Wrapped Concrete Cylinder Pipe, without having made any changes to its structure. While this can be confusing, it relates to the hybrid nature of the product. While it has been used extensively in some of the western states and in most of the far western states (those west of the Rockies), it is a new product to the eastern market, where it is currently being promoted. This paper will address the complexity of the nature of the product, relate to its history and provide an insight to its manufacture and design. Although not a new material by any sense of the word, it is new to many potential users; owners, engineers and contractors. Also, the eastern market will almost certainly involve some variations to the product's historical experience. These variations should not cause undue concern as long as they are recognized. History, experience and knowledge are essential ingredients in providing a beneficial new tool in the pipe industry's tool box.
