KEY-TECH "packaged" plants can be shipped nationally or internationally. Field applications and remote locations are our specialty.
(Capacities from 3 gpm to 30 MGD)

KEY-TECH plants are designed with your application in mind. Design begins with an evaluation of your onsite water characteristics and your specific treatment needs.
The plant is pre-assembled, wired, plumbed, and tested prior to shipment.
Because the plant is "packaged" onsite installation, commissioning, and operation are quick and easy.
KEY-TECH can also provide technical support to trouble-shoot, modify, and optimize your current water treatment systems & processes.
Keystone Water Technologies, LLC has successfully teamed with Wellons and Wellons Water Technology, Inc. to provide a comprehensive line of “packaged” water and wastewater purification plants that serve a variety of municipal, industrial, oilfield, food processing, and agricultural applications.
Keystone and Wellons offer 40 years of water treatment expertise and 40 years of “high- tech” fabrication capabilities respectively, to produce a plant of superior performance and quality. KEY-TECH plants are fabricated in facilities located in Vancouver, Washington or Sherwood, Oregon and bear the “Made in the USA” label.
KEY-TECH plants are individually designed for your specific water treatment needs. Our plants are not “cookie cutter plants” that limit both the capability and capacity that other manufacturers provide as a generic approach to water treatment. The KEY-TECH plant is pre-assembled to the greatest extent before shipping, so it takes a minimum of field assembly to become fully functional.
We invite you to experience the KEY-TECH / Wellons hybrid water treatment plant options for superior water treatment performance and a service life only quality can assure.
