  1. Dynamic licensing – integrated control of urban wastewater systems STREAM-Engineering Doctorate project By: Biniam Biruk Ashagre Academic Supervisors: Dr Guangtao Fu Prof David Butler Industrial Supervisor: Ms Kerry Davidson Safe and Sure project weekly meeting: 29/08/2013 Sponsors:

  2. In this presentation • What is dynamic licensing? • Why dynamic licensing? • Aim and objectives of the project • Study sites • Methodology and Work plan • What is done so far?

  3. What is dynamic licensing • It is an approach that align the real time operation of wastewater treatment plants in harmony with the dynamic capacity of receiving water.

  4. Why dynamic licensing? The use of holistic view inspired by WFD and allow WwTPs to run dynamically in synergy with the environment Suggestion

  5. Aim of the project • The aim of the project is to develop an integrated catchment based control strategy in which several WwTPs can operate optimally using a dynamic licensing approach without affecting downstream water quality.

  6. Main objectives • To come up with a control strategy by integrating river, WwTP and the sewer system so as the WwTPs can operate optimally to: • Reduce energy consumption • Reduce carbon footprint • Meet the effluent quality which is determined by the dynamic receiving capacity of receiving river

  7. Main objectives Figure A conceptual representation of integrated urban wastewater modelling as the first objective. Prepared in collaboration with Sam Dickinson

  8. Main objectives • To come up with a control procedure to optimize catchments for the best possible downstream river water quality while assuring a reduced energy consumption and carbon footprint. Control procedures will be developed for very WwTP based on downstream river quality and upstream WwTPs will work in coordination with downstream WwTPs

  9. Study sites • Cupar catchment • Catchment Area (km2): 307.4 • 9 WwTWs(inc.Cupar) • 1 Septic Tank • 31 network CSOs • Sewer Networks: 10 (7 with CSO’s)

  10. Study site: CuparWwTP Figure Cupar wastewater treatment plant (STOAT)

  11. Study site: Selkirk WwTP Intermittent pumped inlet Replace AS reactors with OD Screen & Skip Storm Screen Upper Intake Sludge Tank Two storage tanks

  12. Study sites • Selkirk Catchment • Catchment Area (km2): 499.0 • No of WwTWs (inc. Selkirk): 1 • 1 Septic Tank??? • No Network of CSOs: 10 • No of Sewer Networks: 2 (1 with CSO’s)

  13. Methodology and work plan
