Their math says: 1mm of rain per square metre = 1 litre saved.
Under the aegis of the Brazil government's project called 'Brazil without misery', the 'Water for Everyone' project works at two levels - it provides water to communities that do not have access to municipal supply and makes the community a stakeholder in its own development.
The harvested rain-water is stored in community cisterns that can be accessed for domestic use and even for the small garden and subsistence farming.
Bruno Maciel Moraes, who works with Banco do Brasil, that finances the 'Cisterns de placas' initiative says, "The community gets empowered. If you are involved, you develop."
The 'cisterns de placas' project that has been working in eastern Brazil for a while now, and the results seem encouraging. In fact, there are 60000 cisterns in 89 counties in Brazil. The target is to reach one million. Though the cost of installation of one such cistern is about 2000 reais (US$1000 approx), given that it can easily help take care of the water needs of 5-6 families for eight months without any trouble, many suggest the returns are well worth the money invested.
