Environmental Enforcement

Industrial monitoring and Sewer Use By-law enforcement

The Sewer Use By-law 1-90 regulates and controls the discharge of water and wastewater into the sanitary and/or storm sewer distribution system within Waterloo Region. The chemical and physical limits outlined in the By-law protect the wastewater distribution system, the wastewater treatment plant operation and ultimately the water quality of the Grand River. 

Responsibilities of EELS include:

  • Monitoring commercial wastewater discharge to ensure compliance with the By-law
  • Investigating conditions that adversely affect the Region's wastewater treatment plants and ensuring corrective actions when a problem is identified
  • Conducting company surveys to understand requirements of ongoing monitoring
  • Performing routine company inspections

Environmental Spills Response

EELS initiate prompt investigation of any reported spills in Waterloo Region and when required, initiate containment or cleanup measures in order to minimize the adverse effects of the spill on the natural environment.

EELS Field Services provide a 24 hour emergency response to environmental spills to ensure any environmental spill occurring in Waterloo Region does not adversely affect the environment or violate the Region of Waterloo Sewer Use By-law. When a chemical spill has the potential to impact the Mannheim or Brantford drinking water treatment plants, EELS must notify the affected parties so preventative measures can be taken.
