No. Straight piping—discharging untreated wastewater directly into the environment—violates Belgian environmental law. The Flemish Environmental Code (VLAREM II) and Walloon Code of Water (CWATUPÉ) prohibit unauthorized discharges, while Brussels enforces the 2023 Water Framework Directive transposition. Non-compliance risks fines up to €100,000 or criminal prosecution under the 2017 Environmental Sanctions Act.
Key Regulations for Straight Piping in Belgium
- VLAREM II (Flanders): Requires all wastewater to be treated via certified systems (e.g., septic tanks with infiltration) or municipal sewer networks. Discharges into surface waters or soil without permits are criminalized under Article 5.1.1.
- CWATUPÉ (Wallonia): Mandates pre-treatment and connection to public sewage systems where available. Illegal discharges trigger penalties under the 2021 Water Code, with enforcement by the Direction Générale des Ressources Naturelles et de l’Environnement.
- Brussels Capital Region: Aligns with EU Directive 2026/1184, banning straight piping entirely. The Bruxelles Environnement agency conducts mandatory inspections, imposing administrative fines (€500–€50,000) for violations detected via aerial surveillance or complaints.
Local authorities prioritize remediation over prosecution, but persistent offenders face escalated enforcement, including forced system upgrades at the polluter’s expense.
