Discussion and Recommendations Investments required for NRW could be self
generated by institutions (for example if tariff reflected real cost recovery)
Twinning is not only one but an important tool
for improving the service efficiencyRecipient twinning also could be expert in
twinning in some other areas
When organization is national twinning with aregion would be more appropriate
