Stormwater utility


Proper stormwater management is critical to preserving the health and quality of our local water sources. However, due diligence comes at a cost. This requires us to fund our stormwater management practices through a user-fee program.

Our stormwater user fee appears on the monthly utility bills of both residential and non-residential property owners in our city.

In Kitchener, we charge a tiered flat fee for stormwater management. A series of rate tiers are calculated based on property type and size of impervious area on the property - the area that produces runoff into our local stormwater system.

For example, properties with more impervious surfaces - such as 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, these properties, which are typically non-residential, pay higher rates than residential properties because they generally contribute more runoff and pollutants to the stormwater system.

The utility also enables us to undertake critical stormwater management projects across our city.
