Richland, TX vs San Antonio, TX

Richland, TX and San Antonio, TX currently share an identical average WaterQ score, each scoring 76 out of 100. Both cities currently carry a B grade overall. Because a WaterQ score is an aggregate across all public water systems serving a city, near-identical scores can still mask differences at the system level, so residents of either city should review their specific water system's record for the most relevant detail.

San Antonio, TX is the larger of the two, with 2.2 million more residents than Richland. San Antonio is served by 9 public water systems, compared with 1 in Richland — 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.
