FAQ
Questions fréquemment posées
What are Quebec's wastewater discharge regulations?
Quebec's wastewater discharge is regulated under the Environment Quality Act (Loi sur la qualité de l'environnement) and its regulations. Key requirements: industrial effluent must not cause harm to the environment, must meet provincial water quality standards, and may require authorization from the Ministère de l'Environnement et de la Lutte contre les changements climatiques (MELCCFP). Municipalities also enforce sewer-use bylaws with specific limits for BOD, TSS, and prohibited substances. BioTerraVa provides regulatory liaison and approval support for all Quebec jurisdictions.
How does winter affect wastewater treatment in Quebec?
Quebec winters with temperatures regularly below -25°C create significant challenges for biological wastewater treatment. Biological activity slows dramatically below 10°C and effectively stops below 5°C. Solutions include: insulated reactor basins, heated influent lines, selection of cold-adapted microorganisms, MBBR technology (more cold-resistant than activated sludge), and increased hydraulic retention times. BioTerraVa designs systems that maintain treatment performance year-round in Quebec's climate.
What are Montreal sewer surcharge rates?
Montreal's sewer surcharge rates are among the highest in Quebec. Industrial dischargers pay surcharges based on BOD and TSS concentrations above municipal limits. Typical rates range from $0.80 to $1.50 per kg of BOD and TSS above permitted levels. For a food processor discharging 300 m³/d at 800 mg/L BOD (vs. 300 mg/L limit), annual surcharges can reach $50,000-$80,000. BioTerraVa designs treatment systems that eliminate or significantly reduce these surcharges.
