Water Billing

Home Living Here My PropertyWater Billing

Changes are coming to Durham Region’s water billing system!

We have upgraded our system to serve you better. Durham Region is committed to providing you with exceptional customer service. We have implemented a new billing system with modernized technology and will be launching a new Customer Portal in early 2020.

As a result, your bill has a new account number. However, you can continue to use your old account number for now. You won’t need to update banking information as your old account number is linked to your new account number. Please be assured that your payment information will be kept secure whether you use your new or old account number.

Consumption and usage charges

Water consumption and sanitary sewer usage charges are based on how much water you use. Consumption is measured by the water meter. It is the difference between the reading used for the previous bill and a current reading. Consumption may be estimated if a current reading is not obtained.

Water consumption

The consumption for the current bill is multiplied by the current year's rate for water.

Revenue from the water consumption charge covers:

Operating water supply plants.
Maintaining the water distribution system.
Maintaining and repairing aging facilities.

Sanitary sewer usage charge

The usage for the current bill is multiplied by the current year's rate for sanitary sewer.

Revenue from the sanitary sewer usage charge covers:

Operating water pollution control plants.
Maintaining the sanitary sewer collection system.
Maintaining and repairing aging facilities.

Service charges

Service charges are billed on a flat-rate basis. They recover the fixed costs of providing water and sanitary sewer services. These charges are billed even if no water is used.

Water service charge

This charge is based on the size of the water meter. Most residential homes are serviced by a standard (16 or 19 mm) meter. Fire protection related costs of the water supply system are recovered from the water service charge. Therefore, the water service charge is greater than the sanitary sewer service charge.

This charge recovers the costs of:

Providing fire protection capacity in the water system.
Installing/maintaining/repairing water meters.
Maintaining water service connections, billing and administrative activities.

The water meter registers the amount of water your household uses. It is used to calculate your water bill. We will send you a bill every three months.

You will receive a meter reading card before the bill. Please use this card to call in the reading on the meter. The meter is usually found in the basement of the home.

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 property.
Billing and administrative activities.

Meter reading

Prior to sending your bill, we will mail you a meter reading card. We ask that you read the water meter then follow the instructions on the card to provide the reading. We ask you to read the meter three times a year to help keep costs as low as possible. We will read it once a year.

If you do not provide a reading, we will estimate your bill.

Is your bill higher than usual?

Reading the meter regularly can help you find leaks, which can result in high bills. A leaky flapper valve in the toilet is a common problem. Other common sources include:

Faulty outdoor sprinkler systems
Water softeners
Furnace humidifiers

Our leak detection brochure can help you find these problems. Learn more about water efficiency at home.
