• LawnStarter, "How Much Is the Average Water Bill in 2026?" (2025-2026 residential water cost study; same dataset mirrored verbatim by World Population Review "Water Prices by State"). Washington, D.C. is not covered by that study, so its figure is the average residential water-only monthly bill from utility-rates.com / DC Water (2026). Note: the national average shown here is the simple mean of the 51 per-state figures (~$45), consistent with the per-state table and with DataPandas's $41.52 reading of the same LawnStarter data; LawnStarter's separately quoted "$78" is a family-of-four heavy-usage scenario (100 gal/person/day), not the average typical bill.
