  • Peter Fuhrmann & Joachim Bley,

    Ministry of Environment, Climate

    Protection

    and the Energy Sector

    The Rhine Basin- Objectives and future tasks

  • The Rhine river basin

    200.000 km

    The Rhine = 3rd biggest European river

    Folie 2

  • The Rhine river basin

    Inhabitants 58 Mio.

    Drinking water for 30 million people

    Main stream 1230 km

    Navigable 825 km from Basel/ Rheinfelden Rotterdam

    9 states Italy, Austria, Liechtenstein, Switzerland, France, Germany, Belgium, Luxemburg, the Netherlands &: European Union

    Coblence CIPR

    Folie 3

  • 1. Nov. 1986 (Schweizerhalle - CH) : Sandoz accident

    Fire, 10-30 t pesticides flowed into the Rhine it caused the death of all aquatic life downstream

    12. Nov. 1986: The Rhine ministers unanimously adopted the Rhine Action Programme to save the ecosystem

    Folie 4

  • Rhine Action Programme (1987 2000)

    Guarantee drinking water Reduce contamination 60 Priority substances: reduction by 50-70 % (1985-

    1995)

    e. g. cadmium,

    lead, mercury, dioxines

    Construction of basins collecting fire extinction water Warning and alert systems

  • Warning and alert plan Rhine

    Folie 6

  • Results of the Rhine Action Programme: Oxygen and invertebrates

    Folie 7

  • Monitoring of water quality

    Results of the Rhine Action Programme:

    Folie 8

  • Salmon 2000 - an impossible target?

    Reintroduction of the

    vanished

    Atlantic salmon

    ( 1958)

    into the Rhine

    Folie 9

  • Programme Rhine 2020: Salmon 2020

    2020: A population of 7.000 21.000 salmon will migrate into the Rhine each year

    Until 2009: 5.638 salmons have returned to the Rhine

    Folie 10

  • Rhine Action Programme: overall result

    strong improvement of water quality

    From a sewer into a living

    river!

    Folie 11

  • ICPR: Programme Rhine 2020 not legally binding

    Surface water quality

    Surface water quantity

    Ecology

    Groundwater quality and quantity

    Integrated management of the Rhine river basin and european directives

    2000: EU Water Framework Directive (WFD) legally binding

    - Coordination unit: river basin

    Target: good status of rivers

    (Chemical, biological (MZB, Macrophytes, Phytoplancton, Fish))

    2007: EU Directive on the assessment and

    management of floods (FD)

    - Coordination unit: river basin

    Folie 12

  • Organisation ICPR: Structure of the co-operation

    Folie 13

  • Macrozoobenthos Makrophytes Fishfauna

    WFD Monitoring Results

    Folie 14

  • WFD - New Challenges

    WFD 2000: EU- Water Framework Directive-

    from water quality to basin-wide ecological river quality

    Hydromorhology Fish life !!! (ecological flow, river structure, river continuity, connection of the breeding grounds to the main river Hydropower, Water extraction)

    Diffuse pollution (Pesticides, P, PAH)

    Diffuse pollution (N) Groundwater

    thermal load of the Rhine-River (Rhine model)

    Folie 15

  • Main Challenges

    WFD 2000: EU- Water framework directive-

    from water quality to ecological river quality

    Hydromorhology Fish life !!! (ecological flow, river structure, river continuity, connection of the breeding grounds to the main river Hydropower, Water extraction)

  • Masterplan for fish-migration in the Rhine-River Example: Salmon & sea trout Source: ICPR

    Folie 17

  • Salmon Programme Rivers- Upper Rhine

    Folie 18

  • Hydromorphology river continuity Example: Kinzig/Schutter catchment

    Folie 20

  • Folie 21

  • Main Challenges

    WFD 2000: EU- Water framework directive-

    from water quality to ecological river quality

    Hydromorphology Fish life !!! (ecological flow, river structure, river continuity, connection of the breeding grounds to the main river Hydropower, Water extraction)

    Diffuse pollution (Pesticides, P, PAH)

    Diffuse pollution (N) Groundwater

    thermal load of the Rhine-River (Rhine model)

    Folie 22

  • Chemical Status Rivers

    Isoproturon

    Bentazon MCPA

    Mecoprop

    Pesticides

    Folie 23

  • AgroEnvironmental Programme Baden-Wuerttemberg

    MEKA, SchALVO (107 Mio. per year)

    By choice water protection measures everywhere

    1 Point = 10 /ha*a

    environmental friendly deployment of liquid manure (towing pipe)

    3

    No ploughing up of grassland- no herbicides 2

    No use of chemical- synthetical pesticides and fertilizers

    8

    Perennial crops to be planted after harvest of plants with high nitrogen-rests in field

    9

    Soil covering with plants in permanent crops (100%, 70%, 40%)

    at 100%

    Mulch seeding technique 6

    Plochingen 10,8 46,4 1145

    Mannheim 42 145 2837

    Length: 367 km Navigation, impounded: 203 km 5 Mio people in catchment, HMWB high P- sensitivity

    Solving nutrient problems in intensively used rivers- The Neckar example P

    Folie 25

  • Status Waste Water Treatment in Baden-Wrttemberg

    > 99 % of the population is connected to a sewer system / waste water plant

    wastewater treatment plants : 990 all comply with 91/271

    public sewers ca. 50.000 kilometers

    94 % storm water treatment installations :ca. 6.900

    Total investments up to now ~ 15 bn Euro, turnover ~ 1bn per year

    Folie 26

  • no measures (36%)

    (o-PO4-P LAWA-Orientierungswert)

    measures to be checked (55%)

    measures necessary (9%)

    P- reduction measures in Baden-

    Wuerttemberg

    Folie 27

  • Example Phosphorus Neckar Neckar: 0,13 - 0,17 mg o-PO4-P/L

    o-PO4-P Input: ca. 50% from municipal wastewater treatment plants (485 t o-PO4-P/a)

    WFD status: moderate

    Objectives in BW:

    0,2 mg o-PO4-P/L in free flowing rivers, but contribution to Neckar ?!

    0,1 mg o-PO4-P/L in impounded (HMWB) Neckar between Plochingen und Mannheim

    necessary reduction : 485 t o-PO4-P/a

    Questions :

    Reduction of P- load by reducing soil P- contents ?

    Possible reduction of P-load by improvement of WWTP (> 91/271) ?
