WATER METERS ARE COMING TO CORNWALL
A new water meter is now required in every home and business serviced by the City of Cornwall. A meter is necessary to measure your water use. Understanding your water use will help you manage your bill. Paying only for the water you use is equitable, fair, and promotes water conservation.
Over the coming months, you will hear from the City and our contractor Neptune Technology Group. Neptune will be installing meters area-by-area from one end of the city to the other.
When it’s time for you to book your installation appointment, you will get a letter from Neptune in your mailbox with instructions on how to book, and how to prepare for your appointment. Appointments will be available during the day, evenings, and weekends to accommodate all schedules. If your water service requires a survey ahead of your water meter installation, you may also hear from the City's Project Consultant, Diameter Services.
Meters will be installed city-wide by Fall 2026 and billing under the new system will begin in early 2027. This will give you a chance to learn more about your water consumption and make changes before consumptive billing begins.
Why water meters?
In 2021, the City commissioned the development of a Water Conservation and Servicing Master Plan. One of the recommendations in the Master Plan is to implement universal water metering at all water service connections in the city.
With water meters, you will be charged for the water you use – not the number of taps, tubs, and fixtures you have in your home. This puts control of your water bill in your hands as you will pay per cubic meter you consume. You can also use your water meter to identify leaks at your property and prevent water damage.
The installation of water meters will also improve the City’s ability to monitor water loss in the distribution system. Finding and repairing leaks and other issues quickly provides operating cost savings that ultimately benefit the rate payer.

How to read your meter
To monitor your daily use:
- Take a reading at a set time of the day.
- Take another reading at the same time the next day.
- The difference between the two readings is your 24-hour water consumption.
Note: If the red sweep hand is moving when all your fixtures are turned off, you may have a leak.
When to expect your meter to be installed
Water meters will be installed area-by-area, starting in the east end of the city. Use the interactive map below to determine your area:
Area | Anticipated Start Date | Area | Anticipated Start Date |

Properties that fall Outside of the main installation areas will be have meters installed on an ongoing basis throughout the project.
The City and Neptune will strive to meet this schedule, however, changes may occur. This schedule will be updated if there are any changes to the project schedule. When your Project Area is opened, you will receive a letter of notification from the City of Cornwall. This letter will contain details on the booking and installation process, as well as the date and location for the public information session to be held for your area. A public information session will be held for each of the Project Areas.
The City will host a public information session for Project Area: East End B on November 27, 2024 at the Civic Complex Salon A from at 6:00 p.m. to 9:00 p.m. Attendees will have the opportunity to ask questions to City staff and subject matter experts about the installation process and the equipment to be installed. Registration is not required.
What to expect during your installation
The installation procedure requires 30-90 minutes to complete, during which time the water will be shut off for a brief period. One meter will be installed per water service entering the property. An adult of at least 18 years of age must be home for the entire appointment. There is no fee for booking and payment information (cash, cheque, credit card, etc.) will not be requested. For your convenience, appointments are available Monday to Friday from 8:00 a.m. to 8:00 p.m. and Saturdays from 9:00 a.m. to 6:00 p.m.
To prepare for the appointment, please ensure your water shut-off valve is accessible and leave ample room for the installer to work.

Future Changes to Your Water Bill: Metered Rates Coming in 2027
Following your meter installation, you will continue to be billed your flat rate and your water bill will not immediately change. Starting early 2027, your water bill will be dependent on your consumption as measured by your water meter. You will receive one bill per meter at your property. More information on future water rates and how to prepare for this transition will be shared in 2026.

What is a water meter? How does it differ from a transmitter? |
A water meter is a device that records water consumption. Your water meter is connected to a radio transmitter, which sends consumption information to a remote reading device that collects this data. This information is then used for billing purposes. |
How are water meters read? |
Your water meter is connected to a radio transmitter, which sends consumption information to a remote reading device that collects this data. This information is then used for billing purposes. This advanced technology eliminates the need for a meter reader to enter your property to collect meter readings. |
Is the radio transmitter technology safe? |
Radio transmitters will be installed outside of your home and will not negatively affect your health. The Neptune R900 transmitters being installed comply with Health Canada Safety Codes. Exposure to radio waves from these meters is very minimal and is comparable to a mobile phone or baby monitor, and less than a wi-fi network or microwave. The R900 device transmits for less than one minute per day and only for seven milliseconds at a time. |
When will installations begin? |
Water meter installations will occur on an area-by-area basis starting in December 2024. Please refer to the installation schedule to determine when installations will begin in your area. |
My shut-off valve is located behind drywall. How can I ensure that the shut-off valve is accessible enough to complete the work? |
Neptune installers are trained to cut into drywall neatly and precisely. An access hole is required to install the meter. Once the installation is complete, this hole may be covered using an access panel. |
Who is responsible for maintaining the meter? |
The City is responsible for any future water meter maintenance, provided you, the owner, take reasonable precaution to prevent any damage to it. It is illegal to tamper with the water meter. |
How can I use my water meter to monitor my water use? |
Take a reading at a set time of the day. Take another reading the same time the next day. The difference between the two readings is your 24-hour water consumption. If the red sweep hand is moving when all your fixtures are turned off, you may have a leak. |
Why is conserving water important? |
Reducing the amount of water we use as a community provides social, economical, and environmental benefits. Reduced treatment costs, energy savings, extended life of the treatment plants and underground infrastructure, and fewer opportunities for untreated or partially treated wastewater to be released back to the environment are just a few of the benefits of efficient water use. |
