14 Membership Fees million per year

15 Financial data Distribution of costs Waste water treatment: 88 % Surface waters: 12 % (flowing waters, dams)

16 Waste Water Treatment

17 treated waste water [Mio m³/a] Waste Water Treatment Quantity of waste water treated annually Overview of annual treated quantities of waste water in WVER plants (2003 to 2010) year

18 Waste Water Treatment Plant operation and enhancement 44 waste water treatment plants 2.2 million population equivalents (industrial and residential)

19 Distribution of costs for treating one cubic meter of waste water Waste water treatment interest personnel costs Capital costs: 47 % Operational costs: 53 % depreciation 28% other sewage tax disposal repairs materials energy

20 Surface Waters

21 Water bodies Why Renaturation? Slow down water flow for downstream flood protection Create zones for controlled flood retention Improve biological and ecological water quality

22 Renaturation River Rur near Körrenzig

23

24 Surface Waters Maintenance of rivers and streams

25 Surface waters 1,900 kilometres of flowing waters 50 flood retention basins

26 Flood Protection

27 Flood Protection Upstream of Settlements 50 flood retention basins for the case of heavy rainfall

28 Retention basin filled

29 Planned for each sub-catchment Prepared by WVER and other authorities Based on range of extreme flood event scenarios (5-, 10-, 20-, 100-, 200-year floods) Results: Which areas will be flooded? What damage expected at which locations? What measures to prevent damage? Flood Action Plans Benchmark: technical flood protection for a hundred year flood

30 Flood Risk Plans Also according to frequency of flooding: Which areas will be flooded, what velocity of flood wave? Which institutions and buildings are affected? What hazard sources are there? Which roads can still be used? Where are relief organisations situated? Important planning criteria for emergency services!

31 Extreme flooding (red colour) (occurs only once in a thousand years) Flood Risk Plans Flooding with frequency of one hundred years (blue colour)

32 Dams

33 Excess surface run-off in the Eifel low mountain range

34 Construction of first dam: the Urfttalsperre

35 Dams Multifunctional use Flood protection Equalization of water run-off Storage of high-quality raw water for drinking water production Storage of raw water for industrial use Hydroelectric power generation Tourism / Recreation

36 Dams 6 multifunctional dams Total capacity 300 million m³ 70 million m³ flood protection storage space

37 Dams URFT DAM OLEFTALSPERRE 465 m above sea level RUR DAM URFTTALSPERRE System of dams in the Northern Eifel 322 m above sea level PAULUSHOF DAM DAM WEHEBACHTALSPERRE UPPER LAKE 281 m above sea level MAIN LAKE 281 above sea level DAM RURTALSPERRE SCHWAMMENAUEL 251 m above sea level POWER PLANT SCHWAMMENAUEL DAM HEIMBACH 214 m above sea level KERMETER TUNNEL POWER PLANT HEIMBACH 165 m above sea level

38 Climate Friendly Energy Generation Electric power consumption and generation in 2011 Gwh total power consumption power generation by combined heat and power plants hydroelectric power generation at dams
