National Size-Band Hubs
Browse U.S. community drinking-water profiles grouped by population-served size bands.
Size Categories
- Small Systems
- Community water systems serving fewer than 10,000 people. Small systems represent the majority of U.S. drinking water systems and often face disproportionate capital and compliance challenges relative to their revenue base.
- Mid-Size Systems
- Community water systems serving between 10,000 and 100,000 people. Mid-size systems occupy a transitional zone — large enough to face complex infrastructure demands but often without the rate base or organizational depth of major utilities.
- Large Systems
- Community water systems serving more than 100,000 people. Large systems typically have more organizational capacity and diversified revenue streams, but face correspondingly larger capital replacement needs and regulatory complexity.
