A lake that learns can change a region. Sam Martin, Director of Communications and Engagement at Cleveland Water Alliance (CWA), shares how Lake Erie has become the world’s largest digitally-connected freshwater test bed—and why that matters for public health, utility costs, and the next wave of water-tech jobs. 

Sam walks us through the water economy—everything from maritime logistics and treatment plants to sensing, analytics, and policy—and explains why real-world testing beats lab demos every time. The CWA acts as matchmaker between innovators and end users, backing pilot projects with insurance and support. It makes a compelling case for Cleveland as a freshwater innovation capital.
