• Seine-Normandy Water Agency, France

Three outputs of Art. 5

• 1. Analysis of uses

• 2. Cost-recovery assessment

• 3. Baseline scenario

3
1. Characterisation of uses

• Aim Signals on main stakes /potential
  consequences of decisions
• E.g. Financial flows compared to
  capitalRichness and affordability /territorial
  distribution

1. What use for Prog of Measures ?

• Better knowledge of water uses? taken in
  significant issues
• Geographical (GIS) database on water uses? 80
  of needed data for Hmodified argumentation,
  cost-benefit cost-effectiveness

7
Cost recovery

• Questions to answer (discussed with stakeholders)
  
• Public transfers
• External effects
• Proportion of environmental costs to services
  payment

8
Subsidies from taxpayers
9
Transferts between Users
Contribute 63M , 2 of total invoice
Contribute 13M, 2 of total invoice
Receive 59M, 5 of total invoice
Receive 20 M, 29 total short term invoice 17
of long term invoice incl. Cap costs
10
Who pays for who ?Pollution external costs
Additional costs due to water treatment 90M
Additional treatment costs 30M
Additional treatment costs 35M (self expense
and connected industry)
Additional treatment costs 0
11
What beyondinitial C-recovery evaluation?

• Who will bear the cost of the PoM?

• Will that change the cost-recovery ratio?

12
Distribution of costs
Here cost dedicated to implementation sector
(different from payer)
Total costs per user category, sub-basin Orne,
40 M/year
Consumer (wash. Powder))

5. Baseline scenario

• Questions to answer
• Likely effects of current changes policies on
  risks
• Sensitive and insensitive variables
• what is to be watched closely?

1. What use for Prog of Measures ?

• Database on current works planned investments,
  costs
• basic measures evaluation, and their
  effectiveness assessment (this being limited
  however)

19
Conclusion

• Article 5 looks likea technocratic exercise
• However it is building toolsthat are
  essentialfor further programming of measures
