Wastewater Effluent Testing
Ensure your facility’s wastewater discharge meets regulatory limits with certified effluent sampling and laboratory analysis.
Ensure your facility’s wastewater discharge meets regulatory limits with certified effluent sampling and laboratory analysis.
If your site discharges wastewater into a municipal system or the environment, you're required to regularly test effluent quality to comply with provincial and federal regulations. Wastewater effluent can contain suspended solids, biochemical oxygen demand (BOD), nutrients (phosphorus and nitrogen), metals, ammonia, oil and grease, and other harmful contaminants — all of which must be monitored to avoid environmental harm and legal penalties.
Under Ontario's Sewage Works Regulation (O. Reg. 129/04) and the Ontario Water Resources Act, regulated sites must perform testing at the final discharge point. If your facility operates under an Environmental Compliance Approval (ECA), your conditions will likely specify what parameters to test, the frequency, and the sampling methods. For many facilities, effluent testing is required monthly or quarterly, but some are required to test weekly or after specific operational events.
Canadian Water Compliance ensures full compliance by providing certified wastewater effluent sampling, accredited lab analysis, and easy-to-read reports that align with your ECA or other permit conditions. Our experts work with your operations staff to meet your regulatory obligations and help identify issues before they escalate into environmental violations.
Wastewater effluent must meet strict discharge limits under Ontario's Environmental Protection Act, the Ontario Water Resources Act, and municipal sewer use bylaws. If your site discharges to a treatment plant or waterbody, your Environmental Compliance Approval (ECA) will outline what you must monitor.
Canadian Water Compliance provides the testing services needed to satisfy these conditions — including monthly, seasonal, or event-based testing. We ensure your reporting is timely, accurate, and defensible in the event of an inspection or audit.
Failing to properly monitor your effluent discharge can result in hefty fines, operational shutdowns, and compliance orders from Ontario’s Ministry of the Environment, Conservation and Parks (MECP). Excess nutrients, oils, solids, or metals in wastewater can harm ecosystems and overwhelm sewage treatment facilities.
Routine testing not only proves due diligence but also helps your team stay ahead of potential system issues. Let us help you mitigate risk by maintaining full compliance and identifying exceedances early.
Our service includes everything you need: on-site scheduling, certified sample collection at your designated outfall or sampling point, and lab analysis at a licensed environmental laboratory.
Whether your facility is industrial, institutional, or commercial, we tailor our service to your ECA or sewer use permit. You'll receive a detailed report including laboratory results, regulatory comparisons, and expert recommendations. We’ll even coordinate recurring testing schedules for your convenience.
