AI is helping find lead pipes in Flint, Michigan

August 23, 2018

The algorithm is saving about $10 million as part of an effort to replace the city’s water infrastructure.

To catch you up: In 2014, Flint began getting water from Flint River rather than the Detroit water system. Mistreatment of the new water supply, combined with old lead pipes, created contaminated water for residents.

Solving the problem: Records that could be used to figure out which houses might be affected by corroded old pipes were missing or incomplete. So the city turned to AI. Using 71 different pieces of information—like the age or value of the home—Georgia Tech researchers developed an algorithm that predicted whether or not a home was connected to lead pipes.

The improvement: Before the software was implemented, only 20 percent of the pipes dug up needed replacement. By contrast, the list of lead pipe locations generated by the software has a 97 percent success rate. This huge jump in accuracy is saving the city enough time and money to remediate an additional 2,000 homes.

Large language models can do jaw-dropping things. But nobody knows exactly why.

And that's a problem. Figuring it out is one of the biggest scientific puzzles of our time and a crucial step towards controlling more powerful future models.
