Intention: This was the only way to reach people at dangerous areas.

Sound travels in mechanical waves. A mechanical wave is a disturbance that moves and transports energy from one place to another through a medium.

It´s not Rocket Science. We went back to basics - innovation of what already exists, not just the creation of new technology.

We used the company´s water pipes to send an audio message.

First we announced there would be water shortage.

To avoid problems with the residents, an emergency tap was placed where they could collect water. An extension tube was connected to an audio amplifier. When people came for water, suddenly the flow was shut, and through the tap, a sound message was heard:

EARTH: Listen to me. I’m the Earth and I’m running out of water. Each drop of water you waste endangers your survival. Think about your kids not having water to drink tomorrow. Close the Tap!

Long term: This action will be repeated in different parts of the country by different water companies, all belonging to Valle de Sula Water Association.

This innovation is a relevant influence for it allows us to speak, in an unexpected way, to people who otherwise would not listen.

Important reduction of water consumption from 450 liters to 150 liters per day was achieved during the campaign.

But the best result was to make a very hard target aware of the importance of water misuse.
