About Us


Rick Williams III

You may not remember my grandfather, Richard Williams, but you’ll benefit from his business philosophy.  I grew up working in the company he founded almost 50 years ago and learned that old-fashioned integrity and honesty were our most important products. They still are.

When I founded Marin H2O and merged it with my family’s water treatment company, Marin Refined Water Systems, it was so I could bring our customers a broader range of services, in addition to our top-notch, guaranteed work.  Now, with one phone call, you can get plumbing construction and repair or installation and maintenance of our water treatment programs.

We are proud to offer our community the highest level of service and products and look forward to doing so for years to come.

Sincerely,
Rick W. Williams III
President
