Rainy River Water Treatment Study and Systems Upgrade
Facing a public health risk from elevated carcinogen levels in its drinking water, the Town of Rainy River needed a practical solution that fit within their existing plant footprint to remedy the situation. KGS Group, in collaboration with the University of Manitoba, conducted detailed pilot studies comparing ion exchange and nanofiltration to determine the most effective, operationally feasible way to reduce carcinogen levels in the drinking water.
Ion exchange was selected because it avoided costly building expansion and offered simpler operations and maintenance for the Town. We then provided engineering services for the design, construction and commissioning of the new ion exchange treatment system, integrating it with the plant’s existing processes and controls.
The upgraded system exceeded Health Canada’s Guideline for Canadian Drinking Water Quality for carcinogens and reduced chlorine consumption by 40%. The project addressed a serious health concern while optimizing use of Rainy River’s existing assets. The Town also received a commendation from the Ontario Ministry of the Environment and Climate Change in recognition of the project’s success.
Project Highlights
- Designed the new ion exchange system and integrated it with existing plant processes
- Reduced chlorine consumption levels by 40%
- New system exceeds Health Canada’s Guideline for Canadian Drinking Water Quality
