Important Notice


Dear Valued Customers,

For over 30 years, Filson Water has served the portable exchange DI water treatment market in central Pennsylvania.

As of June 1st 2026, our DI operations have been acquired by H2O Solutions.  They are operating out of New Kingstown as a satellite office with the same staff you are used to.  However, we have additional resources from H20 Solutions and are proud to be part of their family.

My family and I are grateful for the opportunity, trust, and loyal support you have given us. 

Sincerely,

Rob Filson

President | CEO

Aqua Treatment Service, Inc. | Filson Water, LLC
