Treatment Equipment Company is a sales organization meeting the water and wastewater needs of communities, tribes, and developers throughout the West Coast. Through our complete line of process equipment, we approach our business with one goal: providing our clients with the most innovative and cost-effective treatment solutions available.
Experience. Founded in Oregon in 1969, TEC has been serving the Pacific Northwest for nearly four decades, and we have hundreds of different projects under our belt. We’ve also got some gray hair—our sales team averages over 20 years of experience in the industry.
Knowledge. We know we’re only as good as our people, and that’s why we’re made up of folks who just plain get it. Sometimes it takes a fair amount of book smarts to help a client solve a problem; other times, being practical and using a good dose of common sense is the best solution. Our people do both, and do both well.
Going Green. With the increased awareness and focus on energy efficiency, water reuse, and carbon footprint, TEC has taken a leadership role in understanding and implementing new technologies that help our clients in the Pacific Northwest go green. It was also with this mindset that we expanded our coverage into California and Nevada. TEC continues the firm’s practical, cost-effective approach to business, but focuses on a more limited product portfolio, ensuring that each product represents the most advanced and efficient means of treating water and wastewater on the market today.
