We have been developing water supply and treatment systems since 1965

Opus is a specialist in water treatment - delivering solutions from intakes to treatment and distribution. Our team works directly with our clients to develop treatment systems that meet the local standard requirements and the clients.

We work with small to large municipalities, provincial parks, First Nations, private developers, industrial properties and federal/provincial agencies. Our experience with a diverse range of treatment technologies allows each system to be customized to meet the local objectives.

Technology is a constant focus and we are always assessing the latest against our clients' needs. We are at the forefront of UV disinfection systems and arsenic removal systems, and have evaluation traditional technologies such as rapid rate filtration and dissolved air flotation.

Our team also co-authored the AWWARF Design Manual for Slow Sand Filtration. Whether the objective is a review of treatment options for feasibility, or full service design we have the experience to deliver the project.

Our Water Treatment capabilities include:
