How Water Bills Are Calculated
Most water utilities charge a flat base fee plus a per-unit usage charge.
Formula
Monthly Bill = Base Fee + (Daily Usage x Days / 1,000) x Rate Per 1,000 Gallons
Example Calculation
80 gallons/day, $6.50 per 1,000 gallons, $15 base fee, 30-day month.
- 01Monthly usage = 80 x 30 = 2,400 gallons
- 02Usage charge = 2,400 / 1,000 x $6.50 = $15.60
- 03Total bill = $15.00 + $15.60 = $30.60
