Conformité RESEE et réglementations canadiennes sur les eaux usées
Naviguez dans le Règlement sur les effluents des systèmes d'assainissement des eaux du Canada, les exigences de la Loi sur les pêches et les approbations provinciales avec un conseil expert.
🤖 Aperçu IA
Le Règlement sur les effluents des systèmes d'assainissement des eaux (RESEE) sous la Loi canadienne sur les pêches établit des normes nationales pour les rejets d'eaux usées municipales et industrielles. BioTerraVa fournit un soutien à la conformité RESEE, une conception de système de traitement et une liaison réglementaire pour les installations dans tout l'Ontario, le Québec et toutes les provinces canadiennes.
Défis réglementaires
Canadian Wastewater Compliance Challenges
Canadian wastewater facilities must comply with overlapping federal, provincial, and municipal regulations. WSER sets minimum standards, but provinces often impose stricter limits, particularly for phosphorus and ammonia in sensitive watersheds.
- WSER minimum standards vs. stricter provincial limits
- Phosphorus limits as low as 0.1 mg/L in Great Lakes basin
- Ammonia limits for cold-water fisheries protection
- Municipal sewer-use bylaws with surcharge structures
- Climate adaptation requirements for extreme weather events

FAQ
Questions fréquemment posées
What are WSER requirements in Canada?
The Wastewater Systems Effluent Regulations (WSER) under Canada's Fisheries Act require all wastewater systems to meet minimum effluent quality standards: BOD ≤ 25 mg/L, suspended solids ≤ 25 mg/L, and a chlorine residual limit (if chlorination is used). Systems must also conduct acute lethality testing. These are federal minimums; provinces and municipalities may impose stricter limits. WSER applies to approximately 3,700 wastewater systems across Canada.
What is Ontario Regulation 537/93?
Ontario Regulation 537/93 under the Ontario Water Resources Act regulates industrial sewage works that discharge to municipal sewers or directly to the environment. It requires approval (Certificate of Approval) for construction and operation of industrial wastewater treatment systems. The regulation sets effluent limits for BOD, TSS, oil & grease, and specific contaminants based on industry type. BioTerraVa assists clients with O. Reg. 537/93 approval applications, including engineering reports, site plans, and effluent monitoring proposals.
How do municipal sewer bylaws affect industrial dischargers?
Municipal sewer bylaws regulate what industries can discharge to the sanitary sewer system. Typical limits include: BOD < 300 mg/L, TSS < 350 mg/L, oil & grease < 15 mg/L, pH 6-9, and prohibitions on toxic substances. Many municipalities impose surcharges on BOD and TSS above these limits, ranging from $0.50 to $2.50 per kg. Some municipalities also have pre-treatment requirements for specific industries. BioTerraVa designs pre-treatment systems that ensure compliance with local sewer bylaws while minimizing surcharge costs.
