EU, SIXTH FRAMEWORK PROGRAMME

1. EU, SIXTH FRAMEWORK PROGRAMME EU funded Project: OPTIMA INCO-MPC Partner: INTERGEO Environmental Technology Ltd.- Greece Optimisation for Sustainable Water Management

2. OPTIMA - WP 04 - Techno-economic data– INTERGEO OVERALL OBJECTIVE To establish strategies for optimization of water demand-supply balance to guarantee sustainable development as a major part of the multi-objective optimization approach of the DSS-OPTIMA.

3. OPTIMA - WP 04 - Techno-economic data– INTERGEO OUR TASK - WP04 • Driving forces:Human influences and activities that when combined • with environmental conditions underpin environmental change • Pressures:Pressures exerted on resources and • ecosystems from human activities • State:Condition of resource and ecosystem • Impacts:Results of pressures on the current • state • Responses:Policies,engineering solutions, • programs, etc

6. Issues to Consider • Resource Identification and Quantification • Existing Exploitation Strategies C. Management & Economics D. Existing Environmental Stress E. Access to water and Conflict in Demand F. Water Technology Alternatives Indicators

7. OPTIMA - WP 04 - Techno-economic data– INTERGEO Issues to consider A. Resource Identification and Quantification (i) Conventional • Rivers, streams, springs, lakes • Groundwater (shallow and deep) (ii) Non-Conventional • Sea desalination • Roof water harvesting

8. OPTIMA - WP 04 - Techno-economic data– INTERGEO Issues to Consider B. Existing Exploitation Strategies (i). Dams, Weirs (ii). Reservoirs (iii). Boreholes (iv). Treatment Plants (v). Distribution Systems

9. OPTIMA - WP 04 - Techno-economic data– INTERGEO Issues to Consider C. Management & Economics (i). Demand-Side Management Water Conservation Techniques • domestic wastewater reuse (non-potable uses) • irrigation water reuse, drip irrigation • industrial water recycling and reuse • domestic water conservation technologies

10. OPTIMA - WP 04 - Techno-economic data– INTERGEO Issues to Consider C. Management & Economics • (ii). Supply-Side management

11. OPTIMA - WP 04 - Techno-economic data– INTERGEO Issues to Consider (ii). Supply-Side management practices • conjunctive water use • elimination of fresh water release into sea • aquifer recharge and management framework • reservoir management / evaporation prevention • distribution network management • rainfall harvesting • desalination • surface/Groundwater abstraction control • surface/groundwater risk assessment etc……..

12. OPTIMA - WP 04 - Techno-economic data– INTERGEO Issues to Consider (iii). Cost recovery issues • cost build-up (investment, O & M, design, permitting, land use costs,….etc.) • tariffs and charges • billing and bills collection (iv). Legal and financial mechanisms for sustainability

13. OPTIMA - WP 04 - Techno-economic data– INTERGEO Issues to Consider D. Existing Environmental Stress • Stream flow changes • Groundwater Overexploitation • Water quality and land degradation • Downstream impacts of dams and reservoirs etc….

14. OPTIMA - WP 04 - Techno-economic data– INTERGEO Issues to Consider E. Access to water and Conflict in Demand • Domestic user groups (urban, peri-urban, rural) • Agricultural users • Industrial users • Recreation uses • Navigational uses • Ecological/environmental advocate groups

15. OPTIMA - WP 04 - Techno-economic data– INTERGEO Issues to Consider 5. Water Technology Alternatives Efficiency Indicators (i). Performance • Water supply increase or water demand reduction (ii). Cost • Affordable investment and service costs (iii). Reliability • Life time

Database of existing In-Country Capacity for Water resources Management • resources (types, distribution, volume in place, exploitable volume, etc.) • delivery technologies (centrally managed, community managed, household managed) • Costs build-up (investment, annual O & M, etc) • Delivery cost • Cost-efficiency ratios

17. OPTIMA - WP 04 - Techno-economic data– INTERGEO Expected Output 2. A Framework for Integrated Water Resources Management in the Region inclusive of : legal environmental financial Mechanisms for sustainability.

18. OPTIMA - WP 04 - Techno-economic data– INTERGEO Integrated Water Resources Management Outlook

19. OPTIMA - WP 04 - Techno-economic data– INTERGEO • WP 04 - TASK FRAMEWORK • Identification of the significant water sector problems and objectives-goals of each CASE STUDY • DATA INPUT from WP case study partners • Ranking and dealing with CASE STUDY water issues • Development of suitable alternatives and constraints • Techno-economic database construction • DATA OUTPUT

20. OPTIMA - WP 04 - Techno-economic data– INTERGEO • Discussion-Questions • 1. CONCEPT • Examination of Water-Tech alternatives (Techno-econ assessment): • How much in detail….??On local or state catchments level?? • - Emphasize on DEMAND-consumption practices??? • - According to what % of water saving or % water supply increase, • different alternatives will be examined??.Who will identify the • significance? • Including in the Assessment of Potential Benefits of management practices: • - Estimate the economic benefits of water quality improvement • (Water/Wastewater Treatment Costs Reduction etc..) …???? (eg • appropriate fertilization reduces groundwater nitrate pollution, thus less groundwater treatment required)

21. OPTIMA - WP 04 - Techno-economic data– INTERGEO • 2. DATA REQUIREMENTS • Information input from case studies • We require data-detailed description/assessment on the current water management status of each case study, concerning: • - Driving Forces (eg Intensive agriculture ) • - Pressures (eg. High water demand , use of fertilizers, etc) • State (Water quantity or quality) • Impacts (eg. groundwater level drop, High nitrate concentration) • in order to provide • - Response (eg. Pumping control, drainage reuse)
