3. Introduction • Surface water pollution: Industries Urban drainage systems WWTP Urban areas Overflow from storm tanks Effluent discharge CSOs Runoff Discharge Overflow Receiving water body: Stream, river, lake, wetland, or ocean Runoff Non-point pollution runoff Continuous point pollution discharge Intermittent point pollution discharge Agricultural lands

4. Introduction • Water Framework Directive (2000/60/EC): Achieving ‘good status’ for all waters by…. Or 2027 2015 2021 The 2nd management cycle The 3rd management cycle High The 1st management cycle Good Overall status Mod ‘Oneout, allout!’ Poor Bad High Good Mod Poor Ecological status Good Chemical status Bad Fail Priority substances Hydrological characteristics Biological community chemical characteristics e.g. nutrients, ammonia, metals and their compounds, organic compounds e.g. flow, depth, width, structure e.g. phytoplankton, macroalgae, fish, invertebrates

5. Introduction • Current surface water quality status: a. Ecological status-EU: Figure 1 Distribution of ecological status or potential of classified rivers, lakes, coastal and transitional waters (from European Environment Agency report <European waters- assessment of status and pressures (2012)>) Figure 2 Ecological status or potential of classified river water bodies in different Member States (from European Environment Agency report <European waters- assessment of status and pressures (2012)>)

6. Introduction The number of water bodies per Member State/ number of water bodies in poor status/ number of water bodies in unknown status • Current surface water quality status: b. Chemical status-EU: Figure 3 Percentage of rivers, lakes, groundwater, transitional and coastal waters in good, poor and unknown chemical status (from European Environment Agency report <European waters- assessment of status and pressures (2012)>) Figure 4 Percentage of river and lake water bodies in poor and good chemical status (from European Environment Agency report <European waters- assessment of status and pressures (2012)>) Note: Rivers and lakes of unknown chemical status are not accounted for in the red and green bars

7. Introduction • Main pressures and impacts affecting ecological status: Impacts Pressures Pollution pressures Nutrient enrichment a. Agricultural activities b. Urban Wastewater System (UWWS) pollution discharges Organic enrichment Acidification Air pollution a. Industrial pollution discharges b. Urban Wastewater System (UWWS) pollution discharges Priority substances and contaminated sediments Hydro-morphological pressures and altered habitats Urban development, flood defence, power generation, inland water navigation, straightening and land drainage for agriculture

8. Introduction • Main pressures and impacts affecting chemical status: Impacts Pressures Incomplete combustion processes Polycyclic aromatic hydrocarbons (PAHs) Tributyltin compounds (TBT) Boats and ships (anti-fouling biocide) Heaving metals Mining and waste disposal Bis (2-ethylhexyl) phthalate (DEHP) Octylphenol Industrial pollution discharges Nonylphenol a. Agricultural activities b. Urban Wastewater System (UWWS) pollution discharges Pesticide Household chemicals (e.g. personal care products and medicines) Urban Wastewater System (UWWS) pollution discharges

9. Introduction • Challenges for the wastewater treatment plants: Organic pollutants a. Stringent water quality requirements Nutrient pollutants Priority substances Pesticide Household chemicals Dynamic permitting? Solutions? b. Green house gas emission reduction requirements c. Cost-effectiveness

11. Aims and objectives Aim: The project aims to explore the advantages and disadvantages of the catchment based and real-time-based permitting in an integrated urban wastewater system. • Objectives: • Review on the existing permitting policies in England and Wales, and other typical areas/countries; • Try potential real-time controls on the Benchmark case to acquire the relationships between control variables/effluent quality/operation cost/GHG emission; • Establish the integrated urban wastewater system model for a real-life case and conduct the dynamic permitting research; • Draft a guideline for the innovative permitting approaches; • Write up the degree thesis and the journal and conference papers; • Courses, trainings and conferences;
