Our Story


Rochat family members working in the business.From roof capture to consumption, rainwater, as chemical free potable water, is assured.  And though the rain barrel is a historic symbol of our business, what we offer is engineered, scalable, systems appropriate for single family homes or millions of square feet of commercial roofs. Be it catchment, conveyance, or storage we incorporate the best technology available today. 

What sets us apart is how we evolved and who we are. Denis Rochat entered the water treatment/conditioning business as a salesman over 30 years ago traveling across Ohio and Pennsylvania. Over time he saw that all technology was not created equal nor was all service. By 1997 Denis and his wife Mary committed to realize their vision of excellence as a family business. The Rochat’s founded PerfectWater™, in Denis' hometown, Knoxville, TN. Today they have a reputation for water quality problem solving and responsive, high quality service. Four of their nine children (see picture above) work in the business. They have pioneered rainwater harvesting in East Tennessee, designing and installing the first government permitted, potable rainwater water system in Knoxville. Today the company operates a branch in Nashville and has full time representation in Atlanta. Our many years of experience in the water business help us to give better, less expensive, and faster solutions to our clients

From vendor to client our main rule is the Golden Rule. We strive to be sure that our clients always enjoy the relationship. It’s our responsibility to respond quickly and always treat our clients with respect and fairness.

Our field personnel must become certified within 1 year of employment. We have found that the added knowledge and continuing education requirements of Certification adds value for our clients by providing spot on recommendations and quotations, professional installations, and one stop efficient service.
