The Ultimate Clarifier was invented and developed in Regina, Saskatchewan, Canada. Pat Dunne and Ralph Cook were the co-originators of the concept which led to The Ultimate Clarifier. The original concept for a new type of water and wastewater clarifier began many years ago. It was slowly and carefully developed, until it became The Ultimate Clarifier. The streamlined and modular design allows it to fit the needs of any facility or community size.

We wanted to revolutionize sewage treatment and water clarification – and build something to improve the world.

Now, The Ultimate Clarifier is ready for action.
It is dedicated to the memory of the late Ralph Cook, P.Eng
