Orenco was founded in 1981 in response to widespread failures in Oregon's onsite wastewater systems. Since then, we've grown to become an industry leader, with hundreds of employees and more than 300 points of distribution in North America, Australasia, Europe, Africa, and southwest Asia. You can find our products and solutions in 70 countries, on virtually every continent.

Orenco is headquartered in Douglas County, Oregon, where we have over 400,000 square feet of manufacturing space spread among three locations. Because we're dedicated to engineering-based solutions, more than 10 percent of our approximately 390 employees are scientists or engineers. Orenco's products and technologies appear in numerous technical publications, and our employees are asked to speak at conferences throughout the world.
