Bi-monthly Water Charges

Customers in our District are billed on a bi-monthly cycle. Your water bill is

you have. Most residential accounts have a 5/8" or 1" meter. If you don't know
your meter size please contact the office.

1 ccf = 748 galls of Water.
The first 12 ccf cost $3.7
3 per ccf. Each additional ccf after 12 costs $4.41.
For example if your meter used 15 ccf you would have $5
7.99 in water charges
(12 x $3.7
3 = $44.76)    (3 x $4.41 = $13.23)     ($44.76 + 13.23 = $57.99)
Calculating Your Bill

After you have calculated your water usage and base rate add them together.
For a 5/8" Meter with 15 ccf usage your bill would be $88
.07 for 2 months and
11,220 gallons of water.

Base Rate $28.40 + Water Consumption $57
.99 = Total Bill $86.39
