Installation of Gravity Sewers Using Horizontal Directional Drilling (HDD)
The use of horizontal directional drilling (HDD) has become widespread for the installation of many types of utility services including electric lines, water lines, gas lines, and fiber optic. The minimal amount of surface disruption incurred and reduced restoration required when utilizing HDD makes it a desirable solution for many installations. One type of service where HDD has been less commonly used is for the installation of gravity flow sewers, particularly those whose grade is less than 1%. This is largely due to the difficulty in maintaining accurate line and grade throughout the pilot bore and pullback portions of the installation. Nevertheless, HDD is a viable alternative for many gravity sewer installations. This paper discusses the various techniques used for gravity sewer installation with HDD and discusses the advantages and practical limitations of each method. Included in the paper is a discussion of a novel system developed by the Charles Machine Works, Inc. (CMW®) to verify that proper grade is maintained during the pilot bore portion of the installation.
