What a Temporary Discharge Permit Is

A Temporary Discharge Permit is required to discharge water from construction activities into the City of Kitchener’s storm sewer system. This permit applies to surface water and groundwater from dewatering activities. It does not apply to discharges into:
  • The City’s sanitary sewers
  • The Region of Waterloo’s sewers
Separate approvals must be obtained from the Region of Waterloo for those systems.

When This Permit Is Required

Discharging water into City storm sewers is not allowed without a Temporary Discharge Permit. The permit applies to property owners, developers, consultants, contractors, and City staff who need to temporarily discharge construction related water. These discharges are regulated under the Sewer Use Bylaw to protect public health, municipal infrastructure, and the environment.

Why the Permit Is Important

Protecting water quality in creeks, rivers, and drinking water sources is a shared responsibility, and improper discharges can harm public health and damage ecosystems—including trees, plants, birds, fish, and other wildlife—while non compliance can also lead to financial penalties and cleanup costs under City, provincial, or federal regulations

Before Applying

A permit is required for any construction related discharge to the City’s storm sewer system that exceeds 50,000 litres per day. Applicants should confirm sewer ownership using the City’s Open Data portal.
To verify sewer ownership, visit: Open Data – City of Kitchener.
If the discharge is to Regional or sanitary sewers, applications must be submitted through the Region of Waterloo.
