Water meters

All properties with water service have meters to measure consumption. For questions about your meter, contact customer service at 519-886-2310 or utilities@waterloo.ca

From 2020 to 2024, we are installing new devices that automatically read your meter. We call this 'advanced metering infrastructure' or AMI. 

Use this page to find out how AMI works and when your property will get a new meter reader.

Door-to-door services

City of Waterloo utilities staff always drive city-marked vehicles and carry a city badge. We are aware of scams — people calling to book an appointment or going door to door requesting to check backwater valves inside the home. Most of our work takes place outside the home. We rarely need to inspect inside the home.

If you receive a call, or someone arrives at your door and you are unsure, do not book the appointment or let the person inside your home. Call our Service Centre at 519-886-2310 to confirm that it is city utilities staff.


Meter replacement program

Water meters measure and record the amount of water used in your home and can detect water leaks. We will be replacing water meters that have reached the end of their life cycle. This helps ensure your water meter is running efficiently.

The city has partnered with Metercor to complete all water meter replacements. If you receive a letter in the mail informing you that your water meter needs replacing, you can call to book at 1-888-290-3070 or make an appointment online.

Book a replacement

A Metercor employee will require access to your home to install the meter. For a successful installation, you must make sure:

  • control valves before and after your meter are in working order
  • your meter is accessible, and the area around the meter is clean and free of debris
  • someone over the age of 18 is present at the time of the appointment

There is no cost for the installation of this meter. However, for missed appointments, meters that are inaccessible, or valves are not functional when Metercor staff arrive, a minimum service charge of $91.50 will be applied to your account. 

Metercor employees carry identification, drive Metercor-marked vehicles, and will only show up at your residence if an appointment has been booked. Do not let someone in your house if you are unsure. Call our Service Centre at 519-886-2310 or Metercor at 1-888-290-3070.


How advanced metering infrastructure (AMI) works

Most properties in Waterloo currently have water meters that require a city employee to manually scan a reader once every two months. These small black devices are located outside your property, wired to the water meter inside.

New water meter readers will be installed
A 'smart' water reader, a small white box that fits over the existing reader

In 2020, we started installing new readers that fit over the existing devices. The new readers are distinctly larger and lighter in colour, as pictured. They are sometimes referred to as 'smart' water readers.

Usage data is automatically sent to us

New readers automatically send water usage data to the city using a wireless network that Enova already uses.

Usage data will be measured hourly and customers will be contacted if abnormal usage is detected.

You will have access to consumption data online

Along with new meters, the city is also creating a website where you will be able to monitor your consumption history and trends, along with billing and account changes. It's scheduled to launch in 2024.


Reader installation process

The city has partnered with KTI Ltd. to complete the remaining smart meter reader installations in stages in 2023 and 2024. This is separate from the Metercor water meter installation currently taking place.

When a worker arrives at your property, they will:

  • be clearly identified as a KTI Ltd employee by photo I.D.
  • locate the existing reading device, usually at the side of the property
  • install the new device which will take 5 to 10 minutes

We do not require access to the inside of your building or home. There is no cost to the property owner or disruption of water service.
