I am researching the effectiveness (in the Australian Capital Territory, ACT) of variable message signs in changing water conservation behavior. (In Australia we spell it "behaviour").

In an online questionnaire I asked if ACT residents, having seen the signs that show yesterdays water usage, the daily target and the daily level of dam water storage, if they have changed their habits. It has.

I have then asked about specific behavioural changes eg saving 'greywater' (already used for another purpose) to use on the garden. Have you made that decision / are you considering it?

The answers are very positive.

What I am looking for is any research and / or your thoughts that suggests there is a saturation level and that no matter how much pressure is put on a community, by way of prompts, norms and / or incentives only so many people will change their habits?
