The City of Thorold, in conjunction with the Niagara Region, provides safe, high quality drinking water to residents - 24 hours a day, seven days a week.  Through strategic reinvestment in our water and wastewater infrastructure, we help to ensure it remains in a state of good repair.

Thorold's water and wastewater rates support:

  • safe, high quality drinking water that meets or exceeds all Provincial standards;
  • wastewater services that meet the needs of the community and protect the environment; and
  • well-planned and sustainable infrastructure.

City Water & Sewer Rates:

The City's water and sewer rates are determined through the annual budget process.  To learn more about the City's water rates and sewer rates, please see:

How your bill is calculated:

Water consumption is based on the number of cubic meters (m3) of water used per billing cycle.  For residences, a billing cycle is every 3 months.

The average family of four uses about 1 m3 of water per day, for all indoor water use.  This can increase significantly in the summer due to outdoor water use.

Your bill is calculated by adding your quarterly fixed-service to your consumption charge (based on your water usage).

The table below illustrates an example of the quarterly charges for a residential customer who has used 60 m3 of water:

 2021 Water Sewer bill example Rate ($) Quantity Total ($)
Water Charges      
Fixed service charge (minimum)     52.17
Consumption charge 1.419/m3 60 85.14
Sewer Charges      
Fixed service charge (minimum)     69.77
Consumption charge 1.896/m3 60 113.76
Total bill     320.84

Important water billing facts:

  • Property owners are responsible for all water charges for their property, including their tenants' use;
  • Your water meter determines property water consumption.  If the meter stops working or shows a low reading, your bill may be estimated until a new meter is installed;
  • The City will 'back-bill' for charges not previously billed for service that was actually delivered to the customer due, but not limited to any of the following reasons:  stopped meter, metering equipment failure, water bypass, tampering, fraud, theft.  For more information, please refer to the City's Water-Sewer Back-Bill Adjustments Policy.
  • Future budgets will transfer more of the funding onto the sewer bill and away from the property tax levy.

 Water on Construction Fees

Access to water during construction is charged at a flat rate on a 3 month basis as a ‘Water on Construction fee’.  The building permit application fee includes the Water on Construction fee for the first 3 months of access.  Starting 3 months after the permit issue date, invoices will be prepared and issued by the Finance Department.  Invoices will continue to be issued until the installed water meter is inspected and tagged by the City’s Public Works Department.  Any questions regarding Water on Construction fees or billing should be directed to the Water Clerk at water@thorold.ca.
