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
