Founded in 1991 in the Saguenay-Lac-Saint-Jean region, TDST now serves a vast clientele made up of many large companies as far as Ottawa. Our team, made up of a dozen loyal employees certified in water treatment, provides outstanding service thanks to their expertise and professionalism. Led by owner Sylvain Tremblay, the company was a finalist at the Business Development Awards.

In addition to solving problems related to residential water treatment, the company has experienced strong growth with industries over the past few years. With the increasing demand and high satisfaction rate, we decided to open a new branch that now serves Montreal and its surroundings!

TDST is a member of the Association des entreprises spécialisées en eau du Québec / Région (AESEQ).
