Northwest Pipe Company Announces $7 Million Project


VANCOUVER, WA--(Marketwire - June 4, 2009) - Northwest Pipe Company (NASDAQ: NWPX) reported today that it has received a Letter of Intent from Slayden Construction Group, Inc. of Stayton, Oregon to supply pipe for the Juniper Ridge Hydroelectric Power Project for the Central Oregon Irrigation District.

The Company will supply approximately 14,000 feet of 108" steel pipe valued at approximately $7.0 million for an engineered and custom fabricated piping system. This pipe is expected to be manufactured in the Company's Portland, Oregon facility with delivery scheduled to begin in the third quarter of 2009.

The 3.27 megawatt Juniper Ridge Hydro project is part of the Central Oregon Irrigation District's 22 mile Pilot Butte Canal. The piping portion of the project carries watershed benefits by eliminating water loss through the canal. This loss will place in excess of 20 cubic feet per second of water permanently in the Deschutes River. This additional water will benefit the river habitat and the ESA listed steelhead recently reintroduced downstream. Increased river flows will also enhance water quality conditions of concern to the Department of Environmental Quality under the Clean Water Act.

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 statements regarding the project described above. These statements reflect management's current information about the project mentioned above and 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.
