agglomerations in
each Member State
expressed in million
p.e. and in percent of
the total generated]
Source: European Commission (2020). 10th implementation report
A combination of measures
will be needed
What is the problem?
SD=agglomerations <2 000 p.e., CSO=combined sewer overflows, IAS=individual or other
appropriate systems, The total urban waste water generated is about 612 mio p.e.
Source: JRC Science for Policy, 2019, Water quality in Europe: the effects of the Urban Waste Water Treatment Directive
Small agglomerations
• Source of pollution
• Source of GHG emissions
• Lack of investments
• High use of IAS
Individual and other appropriate
systems
• Source of pollution to surface and
groundwater (esp. drinking water)
• Source of GHG emissions
• Can implicate health issues
• In cases, too much used as
alternative to collecting systems
• Lack of clear definition
• Problem with EN standard 12566
• Not always well maintained and
monitored
Policy measures for small agglomerations
A combination of measures
will be needed

the environment and
climate

Joint workshop on Enhancing efficiency and sustainability of Water Supply and Sanitation presentation - Nele Frederike Rosenstock

  • 1. European Commission DG Environment Nele Rosenstock Revision of the Urban Waste Water Treatment Directive ENHANCING SUSTAINABILITY AND EFFICIENCY OF WSS PROVISION 15-16 June 2021 Disclaimer: The views expressed are purely those of the writer and may not under any circumstances be regarded as stating an official position of the European Commission.
  • 2. • Draft policy measures • Consultation strategy • Roadmap • Externalized studies PREPARATION • OECD • Established models for impacts & costs • 2 baselines: 2016 + full compliance • Expert engagement METHODOLOGY • Evaluation • Information from Member States & operators + consultation on modelling assumptions • Literature review DATA COLLECTION • Quantification/modelling by JRC • Triangulation of evidence ANALYSIS • Web-meetings • Speed dates • Stakeholder workshops • Conference with DE presidency • Online public consultation STAKEHOLDER CONSULTATION • Impact assessment • Proposal Q1 2022 1 2 3 3 4 5 Approach to the impact assessment
  • 3. Long list of policy measures Storm water overflows, runoff Small agglomerations Individual systems Nutrients Sensitive areas Contaminants of emerging concern Sludge management Industrial discharges Energy use/production + climate footprint Monitoring Reporting and information to the public Governance

  • 5. A combination of measures will be needed What is the problem? SD=agglomerations <2 000 p.e., CSO=combined sewer overflows, IAS=individual or other appropriate systems, The total urban waste water generated is about 612 mio p.e. Source: JRC Science for Policy, 2019, Water quality in Europe: the effects of the Urban Waste Water Treatment Directive Small agglomerations • Source of pollution • Source of GHG emissions • Lack of investments • High use of IAS Individual and other appropriate systems • Source of pollution to surface and groundwater (esp. drinking water) • Source of GHG emissions • Can implicate health issues • In cases, too much used as alternative to collecting systems • Lack of clear definition • Problem with EN standard 12566 • Not always well maintained and monitored
  • 6. Policy measures for small agglomerations A combination of measures will be needed Objective: Protection of the environment and climate Policy measures Threshold 1 000 or 500 p.e. Risk-based approach/ link to WFD Definitions “agglomeration” “appropriate treatment” “population equivalent” Disclaimer: all measures may be subject to changes over the course of the IA
  • 7. Policy measures for individual and other appropriate systems A combination of measures will be needed Objective: Protection of the environment and climate A combination of measures will be needed Policy measures Definition of IAS “equivalent protection of the environment” Construction Products Regulation Standard Connect where a system exists Reduce IAS to extent possible (rural vs urban) Improved maintenance National control and inspection strategies Reporting to EC and reduction Disclaimer: all measures may be subject to changes over the course of the IA
  • 8. Investments: polluter pays & investing where it makes sense Administrative burden vs timely provision of relevant data Risk-based approach and/vs EU targets Fit for the future & appropriate deadlines Control at source and/vs end-of-pipe action Implementation & Enforceability Some over-arching considerations ?
  • 9.
