The City of Portland East Side Combined Sewer Outflow Project* is the ISTT 2009 Project Award winner. This project involves the installation of approximately 3,000 ft (910 m) of 84-inch (2m) ID concrete pipe in a single drive under challenging conditions. Difficult mining conditions including soft ground, wood debris, and rail spikes were encountered along the drive. These conditions had largely been anticipated, in the project design and selection of equipment. The result was a highly successful job of recording breaking length. The project team was The City of Portland, Bureau of Environmental Services, Parsons Brinckerhoff, and Kiewit-Bilfinger Berger JV. This project also is receiving the 2008 North-American Project of the Year Award for New Installation.

Aqualiner’s process involves forming a thin walled, high strength stand alone liner of glass-fiber reinforced polypropylene. The product is an inert material, easy to install with a long shelf life. The Aqualiner process* has recently been successfully trialed in the Wessex Water region of the UK and is licensed in Japan.

Intuitive and easy to use, the DigiTrak F2 locating system* is a novel 3-dimensional field-view directional drilling locating system with a single button user interface and graphically driven menu. In addition to highly accurate tracking capabilities, an operator can use the F2 to navigate the drill in situations where obstacles prevent tracking over the drill head, to look-ahead of the drill, and to target steer.
