The convenience factor alone makes the ig900 well worth the switch from bottled water. Add to that its all-in-one build and fresh taste and there’s really nothing like it. A definite win for everyone in the office.
Joseph Roos
Edgewell Personal Care
I want to thank all of you for the service. Edgar’s team was extremely professional and proficient. It is rare that I have the luxury of a contractor performing a service without me having to constantly correct them on safety and professionalism.
Gloria Smith
HR Employee Relations Director
Last year we had four workers’ comp claims due to lifting and replacing those heavy water jugs. And two employees slipped on spilled water from the jug change. Happy to report we have zero claims due to water this year. And everyone really loves the super chilled, fresh tasting water, too!
Donna Tibbits
Facilities Manager
We used the same water system for years, but decided to go for the free week trial. On the first day I had almost 100 emails from employees telling me how fresh and delicious the new water tasted.
Claudia Lewis-Robinson
Very friendly staff. When our system needs servicing they are there to do the job. Water is wonderful and the techs are great. Bottled water is a thing of the past! You need to try the new filtration system from them.
Aurelia Gervasi

Plus, the units are very professional looking and the people who come to install them make sure to give you instructions on how best to operate them. All in all a great product!
Laura Bronkesh
Amazing product, service top notch. Love so much more than other delivery water services we used in the past. We don't need to haul water from my front step onto the holder. Highly recommend!
Brooke Stamas
Optimum Water Solutions is the perfect choice for our office. No more bottled water! The taste is great and the service is fantastic. Lezah Preston made the choice easy. She was informative and brief- which is important when you're busy. So far we love our unit!
Diane Brock
We like the water, ice and hot water convenience for the employees, and the satisfaction of knowing we are providing a superior alternative to tap water. Great service too!

I'm a maintenance manager for a large 3PI and I couldn't work with a better company. I use them at all my warehouse sites. They are always professional, courteous and on time. they do a very neat and professional job on the install, service and follow-ups, and are the best bunch of people to work with.
