The City of Mercer Island is investing in new tools to better serve water customers. In 2024, the City will replace all residential and commercial water meters with an advanced metering infrastructure (AMI) system and create an online portal where customers can track water use, leak alerts, and other notifications.

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

In addition to improving utility operations, Mercer Island customers will see additional benefits including monitoring tools for managing water use through a new online customer portal.





Proposed Data Collection Station Locations

UPDATE | 12/15/23 | The permit application process has been paused for five locations, indicated below. City Council will evaluate alternatives to the identified locations in a Study Session at their March 5, 2024 meeting.

Seven data collection equipment stations will be installed at various locations across the city. These proposed locations were identified based on their ability to effectively communicate with water meters across Mercer Island. Proposed locations include:

  1. Mercer Island City Hall - permit process paused
  2. South Mercer Playfields - permit process paused
  3. Island Crest Park
  4. Water Reservoir
  5. Roanoke Park - permit process paused
  6. Eastside 71st - permit process paused
  7. South Point Landing - permit process paused


Each data collection station will include a 22” by 22” by 10.5” aluminum box base station and a communication antenna which will range from 7’ to 9’ in height, depending on the specific location. Some stations will be located on existing utility poles and infrastructure, but taller poles, ranging from 80' to 100', may be installed in some locations to ensure that data can be reliably collected from all water meters on the island.

The public can provide feedback on each specific site by visiting the Proposed Data Collection Station Map.


Conditional Use Permit Process

The City is conducting early outreach to properties within 300 feet of the proposed sites to inform them about the installations and upcoming permitting process.

Each installation will require the approval of a Conditional Use Permit, which will authorize the use of this equipment as an essential public facility. Once the permitting process is underway, the City will send a Notice of Application to residents within 300 feet of each data collection site. The notification will detail the proposed permit application and opportunities for public comment. Ultimately, a Hearing Examiner will decide on the issuance of each Conditional Use Permit, and a Notice of Decision will be published.

In 2024, the City will replace all residential and commercial water meters with an advanced metering infrastructure (AMI) system and create an online portal where customers can track water use, leak alerts, and other notifications. 

As part of this upgrade, new data collection and communication equipment will be installed across seven locations to connect the AMI system to the City.

Each data collection station includes a 22” by 22” by 10.5” aluminum box base station, and a 7-9' tall narrow antenna. Most stations will be located on existing utility poles and infrastructure. Taller poles will be installed in some locations to ensure that data from all Mercer Island water meters can be collected, and to meet safety guidelines for clearances between power lines and other equipment.
