3. Elevation Surcharge

An Elevation Surcharge is based upon the pressure zone in which the service connection is located. Pressure zones are determined by elements that include elevation and pressure.

Elevation Band Elevation Amount Per
100 Cubic Feet

Pressure zones serving elevations 0 through 200 feet (approximate). Pressure zones served by gravity flow and no pumping required.


Pressure zones serving elevations 200 through 600 feet (approximate). Pressure zones requiring pumping.


Pressure zones serving elevations above 600 feet (approximate). Pressure zones requiring considerable pumping.


Standard Billing Cycle

The standard meter reading and billing cycle for most customers is every two months (bimonthly).

Exceptions to two-month billing:

  • The average monthly bill is estimated to exceed $1,500.
  • There are reasonable and justifiable customer requests for monthly billing.
  • The average monthly bill is estimated to be between $100 and $1,500 and the Customer Services Manager recommends monthly billing based on an evaulation of credit and/or collection problems.

Private Fire Service

Private Fire Services are charged a monthly or bimonthly service charge based on the size of the meter. When a meter larger than 4 inches is required for a single-family residential customer in order to maintain adequate water pressure, the maximum service charge amount shall be set at the 4-inch meter level.

Meter Size (Inches) Monthly Service Charge
5/8 or 3/4 (homes) $17.40
1 23.92
1-1/2 40.10
