Guelph’s stormwater fee helps pay for critical upgrades that help our community prepare for, and recover from, more severe and frequent storms.
The fee is calculated by measuring the hard surfaces that cause rain and melted snow to runoff into the City’s storm sewer system – roofs, driveways, and parking lots etc.
The average amount of hard surfaces on residential properties in Guelph is 188 square metres. We call that Guelph’s Equivalent Residential Unit (ERU) and we use it to calculate monthly stormwater fees for all properties.
- All residential property owners and tenants who pay electricity, water, and wastewater bills pay the same monthly stormwater fee.
- Owners of multi-residential properties are billed based on the number of units in the building.
- Fees for businesses depend on the amount of hard surfaces on their property compared to an average residential property.
The City’s stormwater, water and wastewater charges appear on your electricity bill, but they are not connected to electricity usage or rates.
Stormwater rebates for homes
Stormwater fees and credits for businesses
Because industrial, commercial and institutional properties typically have more hard surfaces that cause stormwater runoff, they pay a fee based on the actual amount of hard surfaces on their property, divided by Guelph’s Equivalent Residential Unit (ERU) of 188 square metres, and then multiplied by the monthly stormwater rate.
For example, here’s the calculation for a business property with 750 square metres of hard surface:
750 square metres/188 square metres = 4 ERUs
Stormwater rate x 4 ERUs = monthly payment
Stormwater credits for business
The City offers stormwater fee credits to industrial, commercial, institutional properties, businesses and multi-residential properties with at least six units.
