Water Bill Top Half

Water Bill

Your Water and Sanitary Sewer bill consists of two main components:

  • Usage Charges
  • Service Charges

The following explains these charges and others. The appropriate boxes are lettered in the sample bill for ease of reference.

Section A: Water Consumption Charge

The water consumption bills you for the volume of water you have used as measured by the water meter. The majority of these revenues recover the costs associated with:

  • Operating the water supply plants
  • Maintaining the water distribution system
  • Replacing outmoded or deteriorating facilities

Section B: Water Service Charge

This charge is based on the size of the water meter. The vast majority of residential homes are serviced by a standard (16 mm) meter. All residential water users, with similar size services, will have the same water service charge regardless of the volume of water used. Customers with larger meters (commercial/industrial users) will have a higher water service charge. The majority of these revenues help recover the fixed costs of providing customers with their water service connection. These costs exist even if the customer uses no water. The revenues help to recover the costs of:

  • Providing fire protection capacity in our water system
  • Maintaining water meters
  • Billing and administrative activities

Section C: Private Unmetered Fire Line Charge

This charge is billed to customers who have their own private fire prevention system. These include sprinklers, hose connections and hydrants. The charge is based on the size of the service connection. Most residential customers would not have this type of service. The costs of fire hydrants located on public property are recovered through the water service charge.

Section D: Sanitary Sewer Usage Charge

The sanitary sewer usage charge is based on the volume of water used. It is calculated by multiplying your metered water usage by the appropriate sewer usage rate. The majority of these revenues help recover the costs associated with:

  • Operating the water pollution control plants
  • Replacing outmoded or deteriorating facilities

Section E: Sanitary Sewer Service Charge

The sanitary sewer service charge is the same for all customers regardless of the volume of sanitary sewer discharged or the size of the water meter. Like the water service charge, these revenues recover the fixed costs of maintaining the sanitary sewer connection. Revenues recover the costs of:

  • Maintaining service connections to the customer’s premises
  • Billing and administrative activities
  • Other Charges

Section F & G: Water & Sewer Main Frontage

If a customer is paying for the installation of a water / sewer main over a period of years, this charge will appear on the bill. Some frontage charges are collected on the local municipal tax bill, however the majority are collected on the water and sanitary sewer bill.

Section H: Collection Charges

Unpaid bills may be subject to further collection charges which would appear in this section.

Section I: Miscellaneous Charges

When a miscellaneous charge is assessed to a bill, the charge code and amount appear on the bill. An explanation of the codes can be found on the reverse side of the bill.

Section J,K & L: Explanation of 'Amount Due Now', '2% Late Payment Charge Effective Date', & 'Amount Due after Date Shown'

Your water and sanitary sewer bill is due as of the date of mailing. The amount Due Now (J) on the billing shows the amount owing if the bill is paid before the Late Payment Charge Date (K). A 2% Late Payment Charge will be applied to the total amount owing on the bill if full payment is not received in our office by the Late Payment Charge Date. Please pay the value shown by the Amount Due After Date Shown (L) column if paying your bill after the Late Payment Charge Date.


Customers are financially responsible for all water that passes through the water meters.
This includes water lost and related sanitary sewer usage charges due to plumbing problems


How is My Bill Calculated?

The water meter registers the amount of water passing through it. In order to calculate the amount of water to bill, subtract the current reading from the last billed reading. By applying the applicable water and sanitary sewer rates to the consumption used, and adding in the appropriate water and sanitary sewer service charges, the amount of the bill can be calculated.
