Saving water sustainably

There are so many things that fall within the concept of Sustainability. These issues related to the environment, but in this case, specifically with natural resources. We already know beforehand that most resources are not unlimited and that require a practical and reasonable urgent actions, so that in a few years they still exist wide.
I can mention, for example, the case of water. For the past few years have been to widen awareness towards a rational use and avoid waste. But nevertheless everyone still spends a lot of water and there is still no generalized notion of good habits for sustainable use. And to change behaviors or habits needs some kind of incentive, avoiding the argument to be more "environmentally friendly" because it does not emphasize the issue of savings. But when I mention saving I'm not restricting to water saving in general, but to pull the argument of saving for the consumer himself. That is, strengthening the concept of savings but in terms of savings to the consumer himself, with a view of how to save more water, less pay, make it to the end of the month with more money.
Able to get this type of message to consumers will certainly help to implement and promote a more sustainable lifestyle at all levels.
