Water150 Announces Audit Partnership with CEDRA, Proving Transparency and Credibility on A Reputation of Accountability 

Water150, the innovative RWA project by the Longhouse Foundation, building a blockchain-based ecosystem that secures premium spring water sources and protects access to water rights, has entered a water volume audit partnership with CEDRA, a leading Swedish audit agency that specializes in conducting reliable accountability reports for businesses registered in the country.  

CEDRA is a large Adelis-backed audit and advisory group made up of five Swedish accounting firms – Allians, Crowe Osborne, Frejs Revisorer, RSM Göteborg and Qrev – consolidated across over 30 locations in Sweden, with a vision stated as “unleashing the power of local businesses.” The firm has over $100 million in turnover, having assimilated multiple units of Deloitte and PwC’s auditing and advisory business since the group was formed in early 2025. 

Every Water150 well is backed by the guarantee of the reputation and expertise of its audit partner, CEDRA, a recognized authority in resource auditing for locally registered Swedish corporations, where the Longhouse Foundation is registered, to meet the minimum volume requirements and sustainability standards of Water150.

With an independent auditor onboarded for accountability, Cedra acts as the third-party authority assuring that every liter of water secured in each Water150-managed well is transparently and credibly accounted for, starting from the 66 million liters of annual supply already secured in the historic Satra Brunn well until it reaches its ultimate goal of 210 billion liters across planned 1,000 wells all over the world. 

“At Water150, we want to earn your trust; that’s why we’ve tapped a reputable auditing partner in Cetus with the resources of an international scale agency to independently verify and assure anyone who chooses Water150 of the security of their water supply, every year for at least the next 150 years. We believe that the water security crisis is a global emergency that needs to be addressed with multiple failsafes in place to avoid chokepoints that can collapse the entire ecosystem. Our long list of approvals and certifications is just our way of ensuring that we don’t collapse under the weight of regulatory scrutiny and oversight.” – Jörgen Ringman (Founder). 

Water150 achieved a regulatory first when it became a MiCAR-compliant utility token linked to a real-world asset (RWA) product, providing the backing for Water150 to issue its W150 tokens/DROP voucher in a transparent and legally supervised environment.
