Design methods for buried pipe are fairly well established, but durability is not normally given proper consideration. Durability of a pipe is a consideration as significant as its hydraulic and structural functions. The definition of a durable concrete pipe contains three variables that must be evaluated: the required performance, the properties of precast concrete pipe, and the service conditions. This paper discusses these variables and presents guidelines on how they can be evaluated and on current countermeasures for anticipated aggressive environments.
