Water should remain abundant, clean and accessible to everyone. PHLASK's mission is to help people find publicly available sources of water, and to impel private enterprises to provide public access to their water infrastructure - simply by PHLasking. Single-use water bottles are costly and wasteful. The PHLASK Ecosystem is a simple, cost-effective way to reduce our dependence on single-use water bottles, and an efficient solution to mitigating many of the negative externalities of consuming single-use plastic water bottles. We hope to normalize water-sharing and challenge the ethics of enterprises who exploit public water sources and environmental sovereignty for profiteering.
