A smart meter reader – a small white box that fits over the existing reader.

AMI Smart Point radios

All water meters connect to a system called Advanced Metering Infrastructure (AMI). Small AMI Smart Point radios send your water use directly to the city.

This means:

  • no more manual readings or home visits
  • faster detection of possible leaks or issues
  • more accurate and timely billing

How smart radios work

Each AMI Smart Point radio sends a secure signal a few times a day. Base stations across the city, shared with Enova, receive the signal and send the data to the city’s system.

This helps us:

  • track water use more accurately
  • find and fix issues sooner
  • keep your billing up to date

Radio safety

Smart Point radios use very low-power signals that last less than a second, only 6 times per day.

These signals are similar to AM or FM radio waves and are much weaker than cell phones or microwave signals.

According to Health Canada and the World Health Organization, these signals are far below safety limits and pose no known health risk.

Your data is secure

Your water meter data is encrypted before it’s sent over a secure wireless network.

We protect your information through:

  • strong encryption, similar to online banking
  • multiple layers of network security
  • limited access – only authorized city staff can see billing information
  • no personal data sent – only the meter reading and Smart Point number

Replacement fees

The City of Waterloo owns all AMI Smart Point radios. 

Do not remove or tamper with your radio. If it’s damaged or removed, a replacement fee will be added to your water bill.

The fee for replacing an advanced meter reading unit is $266.00.
