More than 71% of municipalities who responded to a National League of Cities survey identified water systems as their top infrastructure priority. There are more than 150,000 water systems in the U.S., including the Utah Valley Water Treatment Plant pictured here, 80% of which are publicly owned. Those are among the findings from the National League of Cities "2025 Municipal Infrastructure Conditions Report" released Tuesday. More than 71% of municipalities who responded identified water systems as the top infrastructure priority, the NLC said. The NLC's 2022 infrastructure report also found that water/sewer/stormwater systems topped the priority lists for surveyed municipal governments.
