​More than 100 years ago two inventors by the name of Wallace & Tiernan, worked on a process to disinfect drinking water with chlorination and filtration…which Life magazine later cited as “probably the most significant public health advancement of the millennium” for helping to save countless lives. Just as we did 100 years ago, Evoqua continues to innovate with a laser-like focus on our Purpose: Transform Water; Enrich Life.

We have a more than 100-year history of firsts, and continuous innovation runs deep in our DNA. We not only helped create the industry, but we are continuing to develop the next wave of technologies that will help address the world’s water issues.

Whether it is enabling the simple task of turning on a faucet for a safe drink; ensuring ships across the seven seas are environmentally friendly; helping microelectronics companies make our world operate faster; or working with communities across the world to re-use precious water resources, Evoqua technologies and innovations make it all possible. It’s a key reason we’re the first choice for water solutions across the globe … and helps ensure we’ll continue our industry leadership for decades to come.
