  21. 21. Abstraction<br />“Abstraction” - refers to the volume of water taken from a natural or modified resource over the calendar year.<br />Strong regional variations<br />Eastern Countries (Electricity)<br />Western Countries (Electricity)<br />Southern Countries (Agriculture)<br />Total freshwater abstraction across E.U.<br />288 km3/year<br />500 m3 per capita/year<br />
  22. 22. Abstraction: Industry/Energy Production<br />Energy Production accounts for 44% of total freshwater abstracted across the E.U.<br />Very little consumed <br />Most discharged into surface waters at high temperature<br />Obtained via:<br />Public water supply<br />“self” abstraction<br />Fig. 4.1 Large decline in E. Europe<br />Due to decline in water intensive process (mining/steel manufacturing)<br />Highly water intensive operations abstract their own<br />Principal source = surface water<br />Fig. 4.3 Reductions across E.U.<br />Cooling tower use <br />Recirculation methods<br />Reduced intake<br />Increased efficiency<br />Avoid shutdowns<br />Chemicals and petroleum refinement account for ½ the freshwater used by manufacturing industry<br />
  23. 23. Abstraction: Public Use<br /><ul><li>21% of freshwater abstracted for public water systems</li></ul>Fig. 5.1 Household size: (demographic shift)<br />Increased number of people living alone<br />Larger households use less water per-capita <br />Smaller households contribute to a reduction in effectiveness of water saving measures<br /><ul><li>Includes: households, small businesses, hotels, offices, hospitals, schools, and some industries
  24. 24. Only 20% is consumed and 80% is returned as treated wastewater
  25. 25. Key Drivers:
  26. 26. Population (~497mil. In 2007)
  27. 27. Household size (2.4 in 2005)
  28. 28. Income (appliances)
  29. 29. Consumer behavior (Fig. 5.2)
  30. 30. Tourism</li></ul>Household use: 60-80% of supply<br />60% used for personal hygiene and toilet flushing<br /><ul><li>Groundwater = very important
  31. 31. Sewers, surfaces, and release of wastewater into rivers</li></li></ul><li>Abstraction: Agriculture<br /><ul><li>Accounts for 24% of total water use
  32. 32. Abstraction varies regionally:
  33. 33. 0% in the North
  34. 34. 80% in the South</li></ul>~70 % abstracted does not return to the water body<br />Plant consumption<br />Evapotranspiration<br /><ul><li>Irrigation types utilized:
  35. 35. Permanent (South)
  36. 36. Support (South)
  37. 37. Temporary (North)
  38. 38. Two delivery systems utilized:
  39. 39. Pressure
  40. 40. Gravity
  41. 41. Six countries account for 84% of total irrigated area across the E.U.
  42. 42. Italy, Spain, France, Greece, Romania and Portugal</li></li></ul><li>E.U. Water Quality<br />France<br />Supply and sanitation is generally of good quality<br />Distribution losses are high (26%)<br />Germany<br />Very low per capita water use<br />Advanced wastewater treatment<br />Very low distribution losses (7%)<br />England<br />Distribution losses high (19%)<br />Efforts to increase household metering (33%)<br />Portugal<br />Drinking water is not consistently good<br />Does not comply with EU drinking water directive parameters nor EU wastewater discharge regulations <br />50% of supply zones non compliant for coliforms<br />20% of supply zones non compliance for fecal coliforms<br />Netherlands<br />Water consumption is one of the lowest at 124 liter per capita per day<br />Drinking water network is in good enough shape that treated water does not require chlorination before reaching the consumer<br />
  43. 43. Abstraction Impacts: Basin Overuse<br /><ul><li>Water Exploitation Index (WEI):
  44. 44. Annual calculation of the ratio of total freshwater abstraction to total renewable resource
  45. 45. WEI above 20% = under stress
  46. 46. WEI above 40% = severe water stress
  47. 47. WEI – National and Annual Estimate
  48. 48. Does not fully reflect the level of stress on resources of sub-national regions
  49. 49. Does not account for seasonal variations in water availability and abstraction
  50. 50. Does not account for consumptive use nor water that is returned</li></ul>Image courtesy of: http://www.wfd-croatia.eu/userfiles/image/photogallery/maps/RB_Europe.png<br />
  51. 51. Abstraction Impacts: Saline Intrusion<br />Cause: excessive groundwater abstraction from coastal aquifer causing freshwater level to lower and sea water to flow into aquifer<br /><ul><li>Problem Areas:
  52. 52. Mediterranean
  53. 53. Northern Europe</li></ul>Guadiana Basin<br />Greece<br /><ul><li>Greece:
  54. 54. Agriculture / Tourism
  55. 55. 12 of 19 groundwater bodies (63%) intruded or at risk</li></ul>Annual Abstractions La Mancha Occidental Aquifer and Water-level Recovery<br />http://www.eea.europa.eu/<br />
  56. 56. Conclusions on Future E.U. Water Resource Management<br />Water Pricing Across All Sectors<br />Prudent “water user pays” principal based on volume of water used<br />Drought Management Plans<br />At river basin scaled<br />Shift approach from “crisis response” to “ risk management”<br />Efficiency and Conservation<br />Implementing best technologies and practices<br />Leakage detection efforts<br />Raising Public Awareness<br />Education efforts<br />Concept of “virtual water” within E.U. countries<br />
  57. 57. Conclusion Continued…<br />Tackling Illegal Abstraction<br />Major political and technical challenge<br />Severe penalties for non-compliance<br />Alternative Supplies<br />Demand may still exceed availability<br />Supply-side measures and treated wastewater re-use<br />Desalination<br />Preferable since it increases the total available freshwater resource<br />Does not create incentive to reduce water use nor improve use efficiency<br />Information Requirements<br />Reliable, up-to-date information at the appropriate spatial and temporal scales<br />Use both measured and modeled data to explore the impacts of specific water management scenarios<br />
