Public Displays of Attention

Hi everyone,
-Interactive signage ideas
I'm involved in a water demand management program and I'm looking for more ways to increase the awareness of the issue (and program).

Does anyone have any experience or suggestions in what works in terms of public displays?
-Locations (where to locate- billboard, weekly newspaper ads)
-Figures such as daily water consumption, remaining water in storage etc?

Is there anything else that should be considered?

Thanks and all the best
