Oxford County looks to modernize Sewer Use By-law

Residents may review the proposed changes and offer input by September 4, 2020

Oxford County is taking steps to modernize the Sewer Use By-law (SUB), which regulates wastewater discharge into the sanitary sewer system and storm sewers on County roads. The original by-law, which dates back to 1987, establishes acceptable wastewater parameters for industrial, commercial and institutional customers to support the County’s wastewater systems and protect our natural environment.

Modern Wastewater Treatment Plants (WWTPs) are primarily designed to treat human waste through a largely biological treatment process. They are not designed to remove industrial metals or persistent organic pollutants. The best solution, to safeguard the environment and ensure proper operation of municipal WWTPs, is to prevent these types of contaminants from ever entering the sewer system.

Proposed updates to the Sewer Use By-law include:

  • Adding storm sewers on County roads, with unacceptable pollutants identified;
  • Adding new substances (pesticides, ammonia);
  • New industry-specific requirements (motor vehicle repair, food premises, dental offices);
  • New requirements for spill response, pre-treatment, sampling and analysis and reporting;
  • Revisions to the range of acceptable pH; and
  • A revised enforcement process.

These updates will ensure the by-law is better aligned with current standards of practice and will support the long-term effectiveness of Oxford County’s Wastewater Treatment Plants.

The Sewer Use By-law primarily affects industrial and commercial customers. Anyone interested may review the proposed changes online and submit feedback at by Friday, September 4, 2020Feedback will also be accepted by email at, or by calling 519-539-9800, ext. 3087.
