Switzerland: water protection and cantonal authorization

Human legal review pending. FOEN identifies the federal Swiss water-protection framework and describes micropollutant equipment for selected WWTPs. Zurich illustrates a cantonal regime distinguishing cantonal-authority cases from municipal cases; it is not a uniform national administrative rule. Those pages do not establish the current Fedlex consolidation or an individual authorization, and the Advanced label does not determine programme inclusion.

• Identify canton, authorization, wastewater type and applicable OEaux version.
• The inventory label Advanced does not determine applicability of the micropollutant framework.
• Check the canton and applicable Fedlex version; the Zurich example is not extended across Switzerland and does not equate sewer discharge with discharge to waters.
