Exhibit 99.1

NORTHWEST PIPE REPORTS RECORD RESULTS

Vancouver, WA, October 22, 2008…Northwest Pipe Company (NASDAQ: NWPX) today reported record sales and earnings for the third quarter of 2008. Sales in the third quarter ended September 30, 2008 were $123.4 million compared to $92.0 million in the same quarter of 2007. Net income in the quarter was $10.2 million, compared to $5.1 million in the third quarter of 2007. Per share earnings were $1.09 in the third quarter of 2008 compared to $0.55 per share in 2007.

Water Transmission Results

Revenues for the Water Transmission Group were $77.5 million in the third quarter of 2008 compared to $66.8 million in 2007. Gross profit in 2008 was $14.3 million, or 18.4% of sales, compared to $14.2 million, or 21.3% of sales in 2007.

“We are pleased once again to report strong revenue in our Water Transmission Group,” said Brian W. Dunham, president and chief executive officer of the Company. “While revenues were a little higher than expected, the gross margin was slightly lower. The decrease was primarily due to higher raw material costs imbedded in the cost of our products.”

Tubular Products Results

The Tubular Products Group sales were $45.9 million in the third quarter of 2008, compared to $25.2 million in 2007. Gross profit for the quarter was $12.6 million, or 27.3% of sales, compared to $3.1 million, or 12.2% of sales for 2007.

“This was obviously another very strong quarter for the Tubular Products Group, with a 23% sequential increase in sales over the second quarter of this year, and record margins. While some of our markets slowed due to economic conditions, we continued to see strong demand from the energy market throughout the period,” said Dunham.

Outlook

The Company reported backlog of $235 million as of September 30^th. “The backlog, although down from last quarter, is still very strong,” said Dunham. Bidding activity for the Water Transmission Group over the past three months was lower than expected, but several projects were delayed into the fourth quarter. “At this time, we expect growth in the backlog through the end of the year, which should leave us in a very strong position entering into 2009,” noted Dunham. “Conversely, we are expecting lower water transmission sales in the fourth quarter due to a major project postponement, as well as normal seasonality.”

“In the Tubular Products Group, we are expecting another strong quarter due to energy sales, which we hope will offset weakness in some of our other markets. Slowing demand in parts of our

business, along with falling steel costs which may lead to lower pricing, could combine to make it difficult to maintain our current high margin, but our overall results should be solid.”

“As we look beyond 2008,” continued Dunham, “the long term trends for most of our products look strong. Infrastructure spending, energy development and agriculture all look positive, especially as financial markets stabilize. However, concerns over current economic conditions and the credit markets certainly must be addressed. Looking into next year, we see mixed signals but we continue to be optimistic about our 2009 prospects given that the outlook for our two largest product lines, water transmission and energy, continues to be positive,” Dunham stated. “As financial markets stabilize and the economy recovers, we believe we will be well positioned to continue our growth and capitalize on strong positions within our core markets.”
