The Industrial Monitoring Group regulates the industrial discharges into our wastewater and stormwater systems through ongoing inspections and sampling to ensure the water going into the City’s wastewater treatment plants through wastewater system meets the requirements of the Wastewater Bylaw.

Wastewater coming from commercial water customers is monitored for prohibited, restricted, and surcharge parameters. We collect samples from test manholes near the business and submit them to our Bonnybrook lab for analysis.

We list the limits for contaminants in Schedule A of the Wastewater Bylaw. Our testing is done by our ISO 17025 lab which handles more than 400,000 tests a year.

Steps for sampling wastewater

We collect either a discrete grab sample or 24hr composite samples by using an autosampler.

We place the autosampler in manholes to get a sample of the wastewater going into the sewer system. The autosampler takes samples over a 24-hour period.

For grab sampling, we take a small sample as it is flowing into the manhole. Any sample we take from a place's water as it flows into the sewer system can be used to see if the water meets the bylaw.

Industrial specific information and compliance information documents

An effective relationship between industry and municipal government is essential in effectively disposing of contaminated wastewater and in keeping our environment safe. An important part of this cooperation focuses on removing harmful substances before disposing of wastewater. It is important that every facility be properly equipped to prevent releases of unwanted substances.

Industry Specific information and Best Management Practice (BMP) documents were created to help industries to meet Wastewater Bylaw industrial wastewater discharge requirements.

A written record of all maintenance, cleaning and inspections of your pre-treatment must be kept on file for two years. Download a template of the E2227-Pre-Treatment Maintenance Record Sheet.
