Tampa, FL vs Sacramento, CA

When comparing tap water quality between Tampa, FL and Sacramento, CA, Sacramento currently holds a substantial 21-point lead in average WaterQ score, with a score of 91 out of 100 versus 70 for Tampa. Tampa, FL carries a C grade while Sacramento, CA carries an A. A WaterQ score reflects an aggregate of EPA-reported violations, monitoring data, and compliance history across all public water systems serving each city, so a higher score generally indicates fewer recent violations and a stronger compliance record, though it does not guarantee that every tap in the city tests identically.

Tampa, FL is the larger of the two, with 261,436 more residents than Sacramento. Sacramento is served by 29 public water systems, compared with 21 in Tampa — a difference of 8 systems. A larger number of systems often reflects a more fragmented distribution network spanning multiple utilities, suburbs, or rural service areas, while a single large utility serving a big population can benefit from economies of scale in treatment and monitoring, but may also face more complex, aging infrastructure to maintain.
