Commonwealth Water Purification Co. is a full-service water filtration company dealing in residential, commercial and industrial applications. Our business began in 1982, and we have been servicing clients in Central and Eastern Massachusetts and Southern New Hampshire since that time. Owners, Roger and Cynthia Boucher, are committed water quality professionals. Cindy has a Bachelors degree in Chemistry and Biology and has taken specific courses in water treatment. Roger is a licensed plumber in Massachusetts and regularly attends water treatment seminars. Each inquiry is treated as a private consultation. Customers are asked various questions about their water quality test results to custom design the best possible system for their home or business. Commonwealth Water Purification is not a franchise dealership; therefore, we are able to offer a variety of filtration systems, from softeners to ozone to well-chlorination and others. Our recommendation will depend on your particular needs. One feature that sets our business apart from most other water filtration companies is that we offer a written guarantee on systems that we recommend.
