Californians hear a lot about the lessons they can learn from other areas that have coped with water scarcity, like Israel’s development of desalination or how Australia handled its Millennial Drought, which lasted more than a decade. But not all water issues come down to scarcity. And that’s why looking north to Canada could also provide some inspiration when it comes to technologies to treat water (and ways to save energy in the process), tools for finding and fixing leaks, faster processes for testing water and software for analyzing important water data.
