Since 1973, when decorated Air force pilot and Vietman War veteran, Carl Conway, started the parent company Dominion Well Company, Dominion Water has sought to be a different kind of water treatment company. Our roots are in water well drilling – we really do know well water. Operating with integrity and fairness in every aspect of our business is our highest priority. Naturally we provide active military discounts.

We are the only water treatment company in the Washington Metro area to offer a 12 month money back guarantee of satisfaction.

We are unlike our competition in 3 very distinct ways :

  • We do not employ commissioned salesmen,

  • We are not a franchise organization, and

  • We assemble our own systems purchasing the industry’s best components directly from the manufacturers.

Clear Water,
Dominion Water

Whether you contact Dominion Water for a water analysis, a treatment system installation or a follow up service call, you will find our technicians and office staff to be well spoken and well trained, courteous and most importantly effective in solving your water problems. Dominion Water selects top-notch people and offer them excellent benefits so we expect that they give our customers 100%.


We are a small family owned business and like most family owned companies we go the extra mile to prove ourselves. We are wholeheartedly dedicated to providing our community with the best water treatment products and services. To this end we pledge the following:

  • We will be completely open and honest.

  • We will rely on the intelligence of our customers.

  • We will present the facts without embellishment.

  • We will make every effort to insure that our knowledge of water treatment technology is accurate, comprehensive and current.

  • We will be sensitive to each individual customer’s requirement for information so that they can make logical purchasing decisions.

  • We will never criticize another water treatment company.

  • We will discuss technical differences of other brands for the purpose of comparison.

  • We will obtain and install the best equipment on the market.
