Water scarcity is both a natural and a human-made phenomenon. Although there is enough freshwater on this planet to serve all its inhabitants, it is unevenly distributed and water is often polluted. Especially the developing countries often have an insufficient water infrastructure. Furthermore, mining, agriculture and industrial activities cause contamination of groundwater. GreenSource collects both rainwater and wellwater and its high tech ultrafiltration units are capable of removing contamination in order to provide safe water to the community. Even more, GreenSource is a sustainable playground where children and the community can come together.
