About Us

Water Treatment Technologies, Inc. (Water Treatment Technologies) is owned by Robin and Andrea “Andi” Pettyjohn. Robin has been working in the water treatment industry for over 50 years (Andi says that, like his father before him, if you cut him, he’ll bleed water).

It wasn’t long after Robin and Andi moved to Phoenix that Robin saw a great need for better quality water and better quality water service. They started Water Treatment Technologies, Inc. in January of 1992, concentrating on providing the best water treatment service possible. They then expanded to equipment sales and rentals, as their customer base increased.

Our business has been a success in large part because of our efforts to bring the small town attitude of personalized service, hard work, and ethical business practices to the big city. For 28 years, that’s been our commitment to both our commercial and residential customers.

We pride ourselves at problem solving water treatment equipment issues when you need them solved, not days or weeks later, and ensuring your system is properly maintained so you don’t need to take advantage of our 24×7 emergency water treatment services.
