A small, high-tech Ohio business has developed technology that monitors temperature readings along a full segment of pipe during the curing of the CIPP (cured-in-place-pipe) lining process.

The procedure uses sensors strung by cable inside the pipe to be relined before the liner is inserted into the pipe, explains Jack Conte, president and chief executive officer of Zia Systems LLC.

Mears Group Inc. completed in April a 7,400-foot horizontal directional drilling bore in Jacksonville, FL, a design-build project that allows a regional energy producer to expand its natural gas pipeline to serve new facilities. To complete the project, Mears drilled a 7,400-foot pilot hole 130-feet beneath the St. Johns River bottom to install the 16-inch steel pipe. It is an essential link in a 50-mile pipeline that ends at the Jacksonville Electric Authority (JEA’s) Greenland Energy Center.

Construction on TransCanada Corporation’s long-distance, large-diameter C$5.2 billion Keystone crude oil pipeline reaching from Canada’s Alberta oil fields to markets in the U.S. Midwest is grinding to completion after more than two years of intensive construction activity.

An expanded Damage Prevention & Safety (DP&S) Conference again will be a part of the 2011 UCT (Underground Construction Technology International Conference & Exhibition) scheduled at Houston’s George R. Brown Convention Center Jan. 25-27.

Sault Ste. Marie, MI, like so many other communities, is in the midst of storm-sewer separation upgrades. For many cities, that can mean miles of new pipe or upgraded utilities. Sault Ste. Marie has a unique challenge in that its historic downtown area is essentially an island, with the famous Soo Locks closely adjacent to the excavation area.

In many American cities, the sanitary sewer laterals that connect homes and commercial structures to sewer main lines have been allowed to deteriorate and become a significant source of sewer system inflow and infiltration (I&I), along with other problems.

Following tropical storm Fay in 2008, Tallahassee’s 36-inch fiberglass resin force main, originally installed in 1985, failed in three places after 14-inches of rain fell within a 24-hour period. The three breaks occurred within a two-mile section of the force main that runs beneath the Capital Circle Roadway, a Florida Department of Transportation (FDOT) roadway that is one of the most heavily traveled in the city.

Sekisui SPR Americas, LLC has developed equipment for installing spiral-wound pipe inside damaged or deteriorating host pipe without the need for personnel to enter the pipe. Lining old pipes with spiral-wound pipe is a proven method of trenchless rehabilitation that is used worldwide. Until now in the United States, installing SPR profile spiral-wound pipe has been a man-entry process, limiting its application to pipes large enough to accommodate personnel.
