Position paper on Industrial waste water discharges into sewers

Waste water treatment plants (WWTP) remove pollutants from domestic waste water through mechanical and chemical processes and the biological activity of the biomass contained in the reactors. Chemicals coming from industrial waste water discharges into sewers can pose threats to waste water treatment, human health and the environment.

Therefore, controlling hazardous industrial discharges into sewers is an essential measure for protecting the environment, for the effective and sustainable operation of WWTPs, and to allow operators to comply with the Urban Waste Water Treatment Directive (UWWTD). Any sustainable policy framework must start from the Precautionary Principle, the Control at Source Principle and the Polluter Pays Principle, according to Article 191.2 of the Treaty on the Functioning of the European Union (TFEU).
