Water150 Launches Blockchain-Backed Water Token

The Sätra Brunn well, located in a 324-year-old Swedish village, serves as the foundational asset for Water150’s ambitious project. This well, which has endured since the 18th century, will secure the first 66 million liters of annually replenished mineral water supply starting in January 2027, with commitments extending for the next 150 years. Every water source added to Water150’s network will be measured against the pedigree of this historically reliable natural spring, establishing a benchmark for quality and sustainability.

The tokenization mechanism is straightforward yet revolutionary: each liter of water secured in the Satra Brunn well is fully backed by a corresponding Water150 token (W150) issued on the Ethereum blockchain by Longhouse Water S.A., a Luxembourg public limited liability company. The initial batch of 66 million Water150 tokens will therefore fully back the annual supply from this first well. This creates a verifiable, transparent ecosystem where the amount of tokens in circulation directly corresponds to the volume of annual water flow available—a relationship audited by independent third parties.

What sets Water150 apart in the crowded cryptocurrency space is its regulatory standing. The W150 token has achieved full approval from the European Securities and Markets Authority (ESMA), the body responsible for implementing the Markets in Crypto-Assets Regulation (MiCAR) throughout Europe. This makes it one of the first real-world asset utility tokens to receive such comprehensive regulatory recognition, providing investors with unprecedented legal certainty in the blockchain space.

The ESMA approval signifies that Water150 meets rigorous European standards for transparency, investor protection, and financial stability. This regulatory endorsement is particularly significant given that water rights represent a tangible, essential resource rather than a purely speculative digital asset. The approval under MiCAR establishes a precedent for how real-world assets can be responsibly tokenized within Europe’s evolving regulatory landscape.

According to the Water150 whitepaper published on July 25th, the project’s utility mechanism involves two key components: the W150 token and annual DROP vouchers. Each W150 token automatically issues one DROP voucher per year via its smart contract, redeemable for one liter of premium spring water within the same year. This system will operate for at least 150 years starting January 1, 2027. Importantly, redemption uses and burns the DROP voucher but does not affect the underlying W150 token, ensuring perpetual access rights.

Token holders have flexible redemption options: they can either opt for self-tapping at certified wells or pay for bottling and distribution at competitive rates. This consumer choice aspect distinguishes Water150 from traditional water rights systems, offering both convenience and direct access. The project envisions building a global network of 1,000 premium mineral water sources managed according to the Longhouse Water Quality Standard, which aligns with WHO, FDA, and Swedish National Food Administration recommendations.

At full scale, the envisioned 210 billion Water150 tokens in circulation would back a corresponding quantity of water reserved annually for at least the next 150 years. Each source added to the network will undergo testing according to ISO 17025, the international standard for the competence of testing and calibration laboratories. As the project’s leadership stated: ‘The plan moving forward is to add water sources that build on that legacy and standard to the point that every Water150 token holder has the assurance of quality and security.’
