Local Challenges

Ontario Industrial Wastewater Challenges

Ontario industries face unique wastewater challenges: seasonal cold weather affecting biological treatment, stringent phosphorus limits in the Great Lakes basin, and escalating sewer surcharges in major municipalities.

  • Cold winters (-20°C to -40°C) impacting biological treatment efficiency
  • Great Lakes basin phosphorus limits as low as 0.1 mg/L
  • Municipal sewer surcharges of $0.50-$2.50 per kg BOD exceedance
  • O. Reg. 537/93 industrial sewage works approval requirements
  • Federal WSER compliance for direct dischargers

FAQ

Frequently Asked Questions

What are Ontario sewer surcharge rates for industrial wastewater?

Ontario municipal sewer surcharge rates vary by municipality but typically range from $0.50 to $2.50 per kg of BOD and TSS above the permitted discharge limit. Toronto's rates are among the highest at approximately $1.80/kg BOD. For a facility discharging 500 m³/d at 1,000 mg/L BOD (vs. a 300 mg/L limit), annual surcharges can exceed $150,000. BioTerraVa designs systems that eliminate or significantly reduce these surcharges.

What is WSER compliance in Ontario?

The Wastewater Systems Effluent Regulations (WSER) under the Fisheries Act set national standards for direct dischargers. In Ontario, facilities that discharge directly to receiving waters must meet: BOD ≤ 25 mg/L, TSS ≤ 25 mg/L, and a chlorine residual limit. Municipalities must also meet phosphorus limits. Industrial direct dischargers face additional site-specific limits. BioTerraVa designs treatment systems that meet or exceed all WSER requirements.
