Making Water Work Since 1968

Who We Are


HOH Water Technology is an industrial water treatment provider based in Chicagoland, family-owned and operated for over 50 years. ‍For three generations and counting, we've served commercial, industrial, institutional, and health care facilities throughout the Midwest and beyond, helping them maintain the right water chemistry so their heating, cooling, and industrial processes can perform at the best and most efficient.

Why We're Trusted

We measure our success by how much energy and water savings we accumulate for you while extending the life of your systems and keeping your people safe from waterborne pathogens such as Legionella.

We call this Level 5 Water Care, and we make the results of our program visible to you throughout. The HOH name is trusted across the industry because we deliver results you can see. You never have to rely on gimmicks or guesswork.

What We're
Made Of

Our core values drive everything we do, from how we treat each other and our customers to who we hire. We strive to be the water treatment partner that you cannot live without and are guided by these principles:

We own the results of our work.‍
We believe in claiming value when things go right and taking responsibility when things don’t, owning our part without excuse or debate.


We leave things better than we found them.
HOH exists to serve our customers and improve the operation of their facilities. We take personal ownership of this core purpose in every customer relationship.


We're creative and resourceful.
We find a way to get the job done. We refuse to be boxed in by old solutions that no longer work. If it was easy, anyone could do it.


We work selflessly as one team.
We believe that we go further together. Achieving success for our customers is a team effort, with every member contributing value.

What We Believe

Many companies can run water tests and sell you product, but we believe our people and culture make us different.

Our company mission is to make a lasting impact with water. That mission is two-fold: to deliver a treatment program that works for you at every level, from budget to service to measurable ROI, and, through partnering with organizations like World Vision, to help bring clean water to communities in dire need.
