Dewatering Permits

Dewatering permits are required whenever you are dumping or pumping stormwater (including groundwater, snowmelt and sumpwater) or flushing hydrants into the storm sewer or sanitary sewer system.

We require a Dewatering Permit so we can monitor and control the types of discharges entering our sewer system. We want to lessen the impact on the sewer system and the environment. Before you can dump waste into either a sanitary sewer or storm sewer system, you must have approval from Environmental Services.

You are also required to dump in compliance with local, provincial and federal regulations and in a way that does not violate water quality standards. We may ask you to sample and certify that the discharge complies with the limits of the receiving waterbody, but you will be informed if this is needed during the application process.
