摘要

Much of the world's underground water and sanitary sewer infrastructures are deteriorating and must be immediately rehabilitated or replaced. Long past their useful lives, many systems also are inadequate to meet capacity demands generated by decades of population growth. Because many failing water and sewer pipes are in established urban areas where excavation is difficult or impossible, trenchless construction often is the best and most cost-effective option for installing new pipe. Of the various trenchless procedures available, the most versatile is horizontal directional drilling (HDD), a proven technology widely used to make underground telecommunications, electrical, and natural gas line installations. HDD also is appropriate for public works construction. A growing number of successful projects document the benefits of directional drilling for the trenchless installation of water and sewer pipes, and this paper examines the advantages of using horizontal directional drilling for water and sanitary sewer construction.
