Wide-ranging advances in water technology can reduce the costs of desalination, recycling, and groundwater storage. They help manage smart water grids and root fertilization, enable real-time leak detection and eliminate non-revenue water losses, and improve water distribution efficiencies. The goal of the Lab held in July 2015, was to catalyze and accelerate these kinds of technology transfers and deployments between Israel and California, two global centers of innovation. Based on the Lab, we are organizing work teams to develop potential projects and financial solutions, and to make preparations to deploy them to regions beyond California facing similar challenges. This report present barriers, solutions, best practices and recommendations following the Financial Innovation Lab.
