Water Management Planning
Figure 1-2. Example Information on aWater Bill
(
a) Example shows an increasing block rate structure in which the utility charges a higher rate for increasing increments
of water consumed. Some utilities charge a flat rate regardless of consumption volume, while other utilities charge a
decreasing block rate structure. Water charges take into account total water consumption from all water meters.
(
b) Charge is per amount of water discharged to sewer, which is often billed at a single rate, but could also have
varying rates depending upon the quantity discharged. Oftentimes, this is based on the metered amount of
water use (not a separate wastewater meter), which assumes that all water used was discharged to the sewer. In
some cases, a facility can receive a sewer charge deduction for water uses that are known to not be sent to the
sewer, such as cooling tower evaporation and irrigation water use. This deduction might appear on the bill.
(
c) The utility could charge other fees, including fire service, stormwater, or other base or service charges. Stormwater
fees can be based on the facility acreage. The base or service charge could depend upon the size of the water meter.
(
d) Water usage is for the billing period for a specific water meter. In this example, water usage is reported in units
of hundred cubic feet (ccf). Other common units include gallons and liters. Note: A ccf is equivalent to approxi-
mately 748 gallons.
(
e) In some cases, the utility might provide historical water use information, which can help identify any large leaks
or anomalies. It might also show seasonal trends in water use.
