The SWW Seminar will present the results of the brand new report ‘Abwasserentsorgung 2025’ for BAFU. The report is structured in seven sub-reports that present the state of knowledge on Wastewater Management in Switzerland. Knowledge gaps and need for action are identified and evaluated in an additional report. An overview of legislation and organization of the Swiss wastewater sector is presented in the report “Policy and Governance”. It indicates that management of urban wastewater infrastructure can be optimized regarding the size and form of organizations. The report “Economic Relevance” shows the value of the Swiss urban wastewater infrastructure. An increase of overall costs in the future is expected but will not necessarily have an effect on wastewater fees.

The report “Wastewater Infrastructure” asks for an improvement in data availability of sewer infrastructure data. Although the wastewater infrastructure is already built, some trends could have a substantial impact on this infrastructure. Changes in “Wastewater–quantity and quality” might occur due to climate change, population increase and use of new technologies. The “Influence of wastewater on waterbodies” is most relevant in small streams. Micropollutants are a future challenge for wastewater management. Means for future action in “Urban Hydrology” are the availability of modern rain data with high disaggregation and a systematic approach to handle uncertainty in sewer modeling. “New technologies” in urban wastewater management have emerged in the field of sewer deterioration analysis, in control engineering, membrane technologies, autotrophic nitrogen removal and new sanitation concepts.
