Water and Sewer Services

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.
The Public Works Department maintains all municipal infrastructure including watermain and service repairs, meter installation and repairs, sewer main and service repairs and cleaning. Information regarding the billing for water and sewer consumption can be found at Water and Sewer Billing.
