Utah County has used artificial intelligence to identify roughly 25,000 storm drains that weren’t in its mosquito-control database — a gap that, left unfilled, would have let standing water in those drains go untreated.
The find, reported by KSL TV 5 on Thursday, June 12, 2026, means county vector-control crews now have a substantially larger list of sites to treat each season. Storm drains collect runoff but also trap water long enough for mosquitoes to breed, making them a priority target.
The drain-mapping effort
Locating every storm drain in a county the size of Utah County — which stretches from the Wasatch Front across a wide swath of central Utah — is the kind of task that traditionally ate up field hours. The AI-assisted approach apparently compressed that work, surfacing 25,000 structures crews either didn’t know about or hadn’t logged.
It’s a large number. Utah County’s existing drain inventory, before the AI scan, wasn’t publicly specified in Thursday’s report, so the full scale of the gap isn’t yet clear.
Mosquito-borne illness remains a recurring concern across Utah each summer. West Nile virus, carried by Culex mosquitoes that breed in stagnant water, has caused infections and deaths in the state in past years. Storm drains are among the harder breeding sites to suppress because they’re spread across roads, parking lots, and neighborhoods — often out of plain sight.
Whether Utah County has the staffing and treatment capacity to service all 25,000 newly catalogued drains this season hasn’t been addressed in the available reporting.
