Corrugated aluminum has proven a superior material for storm sewer, culvert, and other drainage pipe applications. Aluminum's wide-spread acceptance and use is based on direct comparison of engineering and economic factors with drainage pipe made of steel, concrete, and other materials. Extensive data were obtained from site inspection and evaluation of similar installations in comparable environments.
Given the longer projected service life in the majority of applications, installation cost savings alone are usually decisive for corrugated aluminum pipe. In many difficult soil or inaccessible site locations, particularly, corrugated aluminum drainage materials are virtually the "automatic choice."
In fact, in-place cost savings are generally the rule and result from the fact that aluminum corrugated pipe weighs only about three per cent as much as concrete pipe. Longer pipe sections are common when aluminum is employed, speeding installation and reducing labor and handling equipment costs (see Fig. 1-1).
The excellent corrosion resistance and strength of aluminum alloys employed in corrugated drainage pipe and fittings have earned official state and federal specification acceptance of aluminum drainage materials.
Today, more than 100-million ft. of corrugated aluminum pipe are in service in the United States as culvert and storm sewers and a wide variety of other types of drainage structures. These corrugated aluminum systems drain all types of roadways, parks, airport landing strips and aprons, forest service access roads, and interstate highways, (see Fig. 1-2). Aluminum pipe is also being employed by municipalities for storm sewers, throughout the U. S. and in other parts of the world.
