NWPX Northwest Pipe Co

Northwest Pipe Company (NASDAQ: NWPX) reports today it has been awarded the contract for the City Trunk Line South Unit 2 project, owned by Los Angeles Department of Water & Power, to furnish approximately 10,500 feet of 66", 60", 54" and 24" diameter welded steel pipe and custom engineered fittings by W.A. Rasic of Bell Gardens, California. The value of the pipe order is approximately $9 million. The pipe will be manufactured at the Adelanto, California facility of Northwest Pipe Company. Delivery will start in early third quarter 2009 and be completed by 2011.

Project Background: The Trunk Line South Unit 2 is part of the City Trunk Line South (CTLS) Project. The CTLS project is part of the Los Angeles Department of Water & Power's (LADWP) aggressive Capital Improvement Program to replace the City's aging water infrastructure system. The Trunk Line has a history of leaks and breaks and will be required to adequately withstand higher pressures in the future. The new Trunk Line will provide a more reliable supply of water to the area and will allow greater operational flexibility of the water distribution system in the City of Los Angeles.

Northwest Pipe Company manufactures welded steel pipe and other products in two business groups. Its Water Transmission Group is the leading supplier of large diameter, high-pressure steel pipe products that are used primarily for water infrastructure in North America. Its Tubular Products Group manufactures smaller diameter steel pipe for a wide range of applications including construction, agricultural, energy, traffic and other commercial and industrial uses. The Company is headquartered in Vancouver, Washington and has ten manufacturing facilities across the United States and Mexico.
