S’well® is a proud partner of UNICEF USA, committing $800,000 since 2015 to help provide clean and safe water to the world’s most vulnerable communities. Through 2018, S’well is focused on supporting water programs across Madagascar – a country where nearly 50% of the population lacks access to clean drinking water. We’re supporting UNICEF’s efforts to build infrastructure, educate families on water-borne diseases and promote national reform to make a sustainable, long-lasting change.
