Water Treatment Services was founded by Alan W. Stevens. Alan was originally a chemist for Colgate Canada and later worked for Drew Chemical and Finnan Engineered Products before forming his own firm in 1976. Water Treatment Services was formed to provide independent unbiased consulting as an alternative to the large water treatment companies whose interests are in selling chemicals. Alan’s technical expertise was demanded across North America as well as overseas. He also instructed water treatment to over 750 building operators in a course carried out at Seneca College in Toronto. Alan’s philosophy “Just what you need and nothing you don’t” remains the core commitment of our company today.

Neill Stevens has over 30 years experience as an independent water treatment consultant to school boards and commercial properties across Ontario. Having never been affiliated with a chemical supplier, he has used his unbiased consulting service to provide a service that has the best interests of the building owners in mind while not pushing unnecessary chemicals.
