Water150, the project developed by the Longhouse Foundation to reserve access to premium spring water through a transparent, blockchain-based ecosystem of natural water springs, is excited to introduce its first natural water well, Satra Brunn.  The Sätra Brunn well is one of Sweden’s oldest and best-preserved natural spring water wells, located in a 324-year-old Swedish village. Every water source added to the network will be measured according to the pedigree and based on the foundations of the historically reliable Satra Brunn natural spring, a well that has endured since the 18th century.
