Water Meter Replacement and Data Collection Stations (AMI) Projects

The City of Mercer Island is investing in new tools to better serve water customers. In 2023 and throughout 2024, the City replaced all residential and commercial water meters.

Once installation of the with an advanced metering infrastructure (AMI) system is complete, the new water meters will automatically transmit data wirelessly to the City through the AMI system, reducing the need for manual meter reads. Customers will also be able to manage water use wisely in the new online portal. Features include trackable water usage, leak alerts, and other notifications.

In order to collect meter readings, the City must install data collection equipment at locations across Mercer Island. The equipment will communicate with the AMI system and the new meters to transmit water usage data to the City.
