How is the Berlin water transition funded?
Berliner Wasserbetriebe utilises a diversified financial architecture that combines cost-covering public-law fees under the Berlin Enterprises Act, green Schuldschein promissory notes aligned with international Green Bond Principles, and long-term European Investment Bank loans such as the EUR 400 million Berlin Water and Climate Adaptation Programme, all guided by internal CO₂ pricing to steer capital toward low-carbon options.

What defines the “Sponge City Berlin” resilience approach?
The resilience strategy replaces rapid rainwater drainage with decentralized retention, evaporation, and infiltration, coordinated by the Berlin Rainwater Agency, using de-sealed pavements, green gullies, infiltration swales, retention soil filters, and annual decoupling of built areas from the combined sewer system to restore the urban water balance and mitigate heat, flood, and drought risks.

How does digital intelligence improve performance?
Digital intelligence integrates process-mining across more than a thousand construction measures, long-range flood and sewer sensors, AI-based sewer aging models, hydrological simulations, and ultrasonic smart meters into central data platforms and control centres, enabling Berliner Wasserbetriebe to predict defects, optimise operations, manage demand, and track progress toward leakage, resilience, and climate neutrality targets.
