Stormwater Utility

Learn more about the stormwater credit.

The City of Kitchener funds stormwater management through a user-fee program.

The stormwater user fee appears on monthly utility bills. The average single dwelling homeowner will be charged about $11.44/per month for stormwater management.

This funding model dedicates dollars specifically to stormwater management - a service that is traditionally underfunded through the tax base.

A tiered flat fee is an equitable approach to charge for stormwater management. A series of rate tiers, calculated based on property type and size of impervious area, account for the varying degrees of water runoff generated from properties that use the system.

For example, properties with a high percentage of impervious surfaces - like buildings, driveways and parking lots - typically create a lot of runoff because these surfaces do not allow water to absorb into the earth. As a result, industrial and commercial properties pay higher rates than residential properties because they generally contribute more runoff and pollutants to the stormwater system.
