Conclusions There are many challenges facing the water resource

sector in the 21st century

Are we prepared for the opportunities that theyrepresent?

The industry will have to change in all aspects from itsworkforce to its business models to meet the changing

expectations Innovation will tend to follow the energy sector in

terms of metering, billing, real time pricing, andbusiness approaches
