Underground Construction and Pipeline & Gas Journal’s worldwide pipeline survey figures indicate that 118,623 miles of pipelines are planned and under construction. Of these, 88,976 represent projects in the planning and design phase; 29,647 miles reflect pipelines in various stages of construction. Almost 32,000 miles of pipeline are currently being planned for North America.
In the early 1990s when compact horizontal directional drill (HDD) models began to appear on utility job sites, project owners often expressed amazement when a drill operator brought the drill head to the surface at or near the projected target.
Pipe bursting is a technology that has matured in North America since the early 2000s. Although this technology has been proven internationally and more so domestically, there are many common myths and/or misconceptions that exist in regards to the technology and its practical application. In January 2012, the IPBA released a guideline for pipe bursting that provides support and reference to the items discussed in this article.
That the United States (and world) economies are mired in a deep recession is old news. For the horizontal directional drilling industry, this recession is much broader than in 2001 when the telecommunications market imploded.
In 2004, Michels Directional Crossings set a horizontal directional drilling (HDD) industry record for its completion of two parallel 7,080-foot-long, 8-inch diameter steel high voltage transmission lines beneath the Cooper River in Charleston, SC.
STAR ZoneScan, developed by Aclara, is an advanced automated detection system that can pinpoint underground leaks in water mains to within just three feet by collecting and analyzing acoustic data, thus helping to speed repair and identify trouble spots before they become major problems.
Many United States municipalities and utility districts face federal Environmental Protection Agency (EPA) mandates to correct water quality problems caused by discharges from combined sanitary and storm sewer systems.
