Water Protection Regulation

What is the Drinking Water ProtectionWater Control Room Regulation?
On June 12, 2003 the Province of Ontario introduced legislation to improve the quality of drinking water throughout the province. Provincial Regulation 170/03 requires that public water quality reports be produced annually by large municipal drinking water systems. The regulation focuses on the treatment and testing of drinking water including specific provisions for public access to information, and notification of adverse results.

Water quality is reported annually in compliance with Ontario Regulation 170/03. These annual reports must include:

  • a description of the water supply system
  • the water treatment process
  • quality assurance methods
  • measures taken to comply with the regulation; and
  • a summary of water quality analyses for the year.

Reports must be completed no later than 60 days after the end of the calendar year, and submitted to the Ministry of the Environment (MOE). Water supply owners must advise their consumers of the report, and ensure that copies are available free of charge upon request. In addition, all waterworks serving more than 10,000 people must post their reports on the internet.

The City of Thunder Bay is dedicated to providing citizens with a safe drinking water supply. Residents can have confidence that their water treatment plant has highly effective water treatment and quality assurance processes in place to ensure the absence of harmful substances and disease-causing bacteria such as e.coli in tap water.

In December 2005 the MOE introduced Bill 43, Clean Water Act. The purpose of this Act is to protect drinking water at its source as recommended by the Walkerton Inquiry. Bare Point Water Treatment Plant Thunder Bay Canada

The Clean Water Act became law in 2006. It requires communities to create and carry out a Source Water Protection Intake Zone Study to protect the sources of their municipal drinking water.  The City of Thunder Bay, in conjunction with the Lakehead Region Conservation Authority, has completed an Intake Protection Zone (IPZ) study at the Bare Point Water Treatment Plant.
