Northwest Pipe Company Announces $19M Order


VANCOUVER, WA--(Marketwire - June 2, 2008) - Northwest Pipe Company (NASDAQ: NWPX) reported today that it has received a letter of intent from Don Kelley Construction, Inc. to supply pipe for the Lewis & Clark Regional Water System.

The Company will supply approximately 57,000 feet of 54" steel pipe valued at approximately $19 million for an engineered and custom fabricated piping system. The pipe is expected to be manufactured in the Company's Saginaw, Texas division with delivery scheduled to begin in the third quarter of 2008.

The Lewis and Clark Rural Water System developed a groundwater supply adjacent to the Missouri River and a water treatment facility in southeast South Dakota near Vermillion. Treated water will be piped to member municipalities and rural water systems. When complete, the project will provide safe, reliable drinking water to approximately 200,000 people in South Dakota, Minnesota, and Iowa. The Lewis and Clark Rural Water System represents a unique regional approach by the three states to address common problems with area water resources in a more effective and cost-efficient way than each state could do alone. This supplemental water supply will allow the Water Service Area to maintain the existing quality of life and will sustain the present rate of growth in the Water Service Area.

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.

This release contains forward-looking statements, including but not limited to those regarding the project described above. These statements reflect management's current views and estimates of market circumstances, industry conditions and Company performance. Actual results could vary materially from the description contained herein due to many factors including market demand, operating efficiencies, availability and price of raw materials, and other risks described from time to time in the Company's reports to the Securities and Exchange Commission.
