How a Directional Drilled River Crossing Water Main Saved Significant Permitting Requirements, Construction Time, and Money, Aroostook River, Caribou, Maine
Utilizing horizontal directional drilling for the installation of a river crossing water main saved the Caribou Utilities District in Caribou, Maine significant permitting requirements, construction time and money. The Caribou Utilities District in Caribou, Maine, recently transitioned from a surface water source to a new groundwater source. The District retained the services of Wright-Pierce of Topsham, Maine, to design the wells, pump station and transmission mains. A 12-inch ductile iron water transmission main was used to bring water from the wells and pump station to the distribution system, for the entire length except for a required river crossing, which was installed by horizontal directional drilling (HDD). This paper will address processes by which HDD was selected as the best alternative for the river crossing, the permitting benefits of selecting HDD, problems encountered during construction, and the lessons learned from this interesting project.
