Water150’s MiCAR-Compliant Token: First Regulated RWA for 324-Year-Old Well’s Hydration Project

Water150, a blockchain-based initiative led by the Longhouse Foundation, has launched its first natural spring water well, the Satra Brunn, marking the beginning of a 150-year hydration project anchored in real-world assets (RWA). Located in a 324-year-old Swedish village, the Satra Brunn well has been secured to provide 66 million liters of mineral water annually, starting January 2027. Each liter is backed by a Water150 (W150) token issued on the Ethereum blockchain by Longhouse Water S.A., a Luxembourg-based entity. The project aims to tokenize access to premium spring water through a transparent, regulated framework, leveraging blockchain to ensure traceability and sustainability title1^[1].

The W150 token has achieved a landmark milestone as the first RWA utility token to receive full compliance with the European Union’s Markets in Crypto-Assets Regulation (MiCAR). This regulatory approval, granted by the European Securities and Markets Authority (ESMA), positions Water150 as a pioneer in the RWA sector, which is projected to reach $30 billion in value. MiCAR’s stringent requirements ensure that the token operates within a legally supervised environment, enabling future listings on MiCAR-compliant trading platforms. The token’s whitepaper aligns with Title II of Regulation (EU) 2023/1114, emphasizing transparency and accountability title2^[2].

The Satra Brunn well serves as a historical and ecological cornerstone for the project. With a legacy dating to the 18th century, the well is managed under the Longhouse Water Quality Standard, which adheres to guidelines from the World Health Organization (WHO), the U.S. Food and Drug Administration (FDA), and Sweden’s National Food Administration. Independent third-party audits verify water quality, with testing conducted under ISO 17025 standards. The well’s inclusion in the project underscores Water150’s commitment to preserving natural resources while integrating blockchain technology for long-term stewardship title3^[3].

Water150’s token model is designed for scalability and sustainability. The maximum supply of 210 billion W150 tokens will represent 210 billion liters of water annually, with each token granting a 150-year right to one liter of water from the project’s network of 1,000 certified springs. Tokenholders receive annual DROP vouchers, redeemable for one liter of water at any certified well. The DROP vouchers are burned upon use, but the underlying W150 tokens remain, ensuring perpetual access rights. This mechanism allows holders to choose between self-tapping at wells or paying for bottling and distribution title4^[4].

The project’s regulatory and technological framework has drawn attention from industry experts. Sören Müller, COO Web3 at Water150, emphasized the significance of MiCAR compliance, stating it reflects the company’s dedication to “credibility, accountability, and transparency.” He noted that the approval also accelerates the RWA sector’s growth, particularly in a post-MiCAR regulatory landscape. The project’s transparent structure, combined with its focus on sustainability, differentiates it from speculative crypto projects, offering a tangible use case for blockchain in resource management title5^[5].

Water150’s roadmap includes expanding its network to 1,000 premium springs globally, with the Satra Brunn well serving as a benchmark for quality and operational standards. The initiative aims to address water scarcity by securing long-term access to high-quality sources while leveraging blockchain to democratize ownership. As the project scales, it will continue to adhere to MiCAR guidelines, ensuring compliance across the European Economic Area (EEA). The integration of historical resources like Satra Brunn with modern technology highlights a unique approach to balancing tradition and innovation in resource preservation title6^[6].
