Rainwater System Testing
Ensure your harvested rainwater is safe for use with certified testing for bacteria, metals, and other critical contaminants.

Rainwater harvesting systems are an excellent way to conserve water and reduce dependency on municipal sources, especially in rural or off-grid properties. However, without proper testing, collected rainwater can pose serious health and safety risks due to the accumulation of microbial, chemical, and particulate contaminants from roofs, gutters, and holding tanks.
Canadian Water Compliance provides specialized testing for rainwater systems, analyzing for E. coli, total coliforms, metals, pH, turbidity, and total dissolved solids (TDS) to ensure the water meets safe usage standards. Depending on the intended use—whether for irrigation, toilet flushing, or even human consumption—different parameters may apply.
In Ontario, rainwater that is used for potable or personal use must meet the standards outlined in the Ontario Drinking Water Quality Standards (ODWQS) and Health Canada’s Guidelines for Canadian Drinking Water Quality. Regular testing is crucial for identifying contamination from bird droppings, decaying plant matter, or roof materials that can leach harmful substances into the system.
Best practices recommend testing rainwater systems at least once per season—especially in spring and fall—and after any maintenance, filter change, or visible contamination event. Our team offers certified sampling, accredited laboratory analysis, and detailed reports with actionable recommendations tailored to your rainwater usage.
Rainwater is only as clean as the surface it’s collected from. Bird droppings, decaying leaves, and roof materials like tar, asphalt, or lead-based paint can introduce bacteria, heavy metals, and chemicals into your water supply. When left unmonitored, these contaminants can pose serious health risks—especially if the rainwater is used for cooking, drinking, or bathing.
Our testing ensures your system remains safe, effective, and compliant with provincial water quality guidelines.
The parameters you need to test depend on how you use your rainwater. For potable or greywater applications, testing should include microbial indicators like E. coli and total coliforms, as well as chemical contaminants like lead, zinc, and nitrates. Systems used for toilet flushing or irrigation may still need monitoring for odour, discoloration, or clogging risks.
Canadian Water Compliance customizes testing packages to your needs and delivers comprehensive lab-certified reports that meet the expectations of building codes, public health units, and insurance providers.
Our rainwater testing includes professional sampling by certified technicians, lab analysis at an accredited Ontario laboratory, and detailed results with reference to regulatory benchmarks. If an issue is found, we provide recommendations for treatment, such as UV disinfection, filtration upgrades, or pre-tank screening.
Our goal is to give you not just numbers—but a full understanding of your water quality, compliance status, and how to improve it.
