Drinking Water Quality

The Ontario government has enacted a new drinking water regulation under the Safe Drinking Water Act, 2002.. These changes were designed to safeguard the quality of Ontario's drinking water, while making the regulatory requirements more workable and affordable for owners and operators of municipal and non-municipal drinking water systems.

Ontario's Drinking Water Systems Regulation 170/03, made under the Safe Drinking Water Act, 2002, governs the operation of municipal drinking water systems.  This regulation provides specific requirements that municipalities must adhere to in the operations of these systems, including:

  • water system operational checks;
  • water quality sampling/testing and reporting; and
  • corrective action requirements.

Drinking Water systems

The City of Thorold owns and operates three drinking water systems that fall under this regulation:

  • Thorold Decew Distribution System (No. 220004313)
  • Thorold Port Robinson System (No. 260049582)
  • Thorold South End System (No. 260049621)
