Northwest Pipe Company Announces $17M Order


VANCOUVER, WA--(Marketwire - November 20, 2008) - Northwest Pipe Company (NASDAQ: NWPX) reported today that it has received a Letter of Intent from Garney Construction of Kansas City to supply pipe for the Prairie Waters Project for the City of Aurora, Colorado.

The Company will supply approximately 75,000 feet of 60" and 17,000 feet of 30" steel pipe valued at approximately $17 million for an engineered and custom fabricated piping system. The pipe is expected to be manufactured in the Company's Denver, Colorado division with delivery scheduled to begin in the first quarter of 2009.

The Prairie Waters Project is designed to provide a reliable supply of high quality water to the City of Aurora by drawing water from the South Platte River through collector wells.

The water will then be piped 38 miles south to the Aurora Reservoir where it will be treated at a new water purification facility. It is anticipated to deliver up to 10,000 acre feet of water by 2010 and up to 15,000 acre feet by 2012.
