How do you replace all the lead pipes in Flint when you don’t know how many there are? It’s a problem now faced by multiple municipalities realizing they have incomplete plumbing records and water contamination around the U.S. The City of Flint, Michigan, has been sending data to a company called BlueConduit to speed up an incredibly complex overhaul of lead service lines leading to houses across the city. BlueConduit programs what data they have into an AI-powered system designed to predict where lead pipes are likely to be found. This speeds up the process of locating most lead pipes in the least amount of time. For a while, the city returned to the more ordered but slow process of digging up every house’s lines one at a time, but it was proved so inefficient and ineffective at targeting the areas with the most lead pipes that the city was ordered to go back to using the AI system to speed up the process for public safety.
