The City of Mercer Island is investing in new tools to better serve water customers. In 2024, the City replaced the majority of residential and commercial water meters, and is working to implement an advanced metering infrastructure (AMI) system and 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 six key locations across Mercer Island. This equipment communicates 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. The customer portal is expected to go live in fall 2024.

Please note that due to a delay in the deployment of data collection stations, the customer portal will only be available for a portion of meters on Mercer Island. Once all data collector stations are installed and activated, this online portal will be available for all water customers.


Proposed Data Collection Station Locations

A total of six 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.

  1. Island Crest Park - permit approved, base station activated
  2. Water Reservoir - permit approved, base station activated
  3. Roanoke Park - permit currently under review
  4. Crestwood area, near SE 43rd St and 94th Ave SE - public outreach underway
  5. West Mercer Way and SE 32nd St. - public outreach underway
  6. West Mercer Way and East Mercer Way (south end) - public outreach underway

Each data collection station includes a 22” by 22” by 10.5” aluminum box base station and a communication antenna that ranges from 7’ to 9’ in height, depending on the specific location. Some stations are located on existing utility poles and infrastructure, but some will be mounted on new 55' tall utility poles.

Conditional Use Permit Process

Before applying for permits for the three remaining base station locations, the City will conduct early outreach to properties within 300 feet of the proposed sites to inform them about the installations and upcoming permitting process.

Each installation requires 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 sends a Notice of Application to residents within 300 feet of each data collection site. The notification details the proposed permit application and opportunities for public comment. Ultimately, a Hearing Examiner decides on the issuance of each Conditional Use Permit, and a Notice of Decision will be published.

    Once a new location has been proposed, detailed information about the site will be posted on this site.  In addition, every property within 300' of the new location will be notified via a mailer and doorhanger.

    John RD asked 12 months ago

    Public Works will continue to answer questions about this project throughout the process. Once the permit applications have been submitted, residents and businesses within 300 feet of each proposed location will receive additional information about the applications, the timing for the formal 30 day comment period, and the public hearing from the Community Planning and Development Department.  The public hearing, which will follow the comment period, has not yet been scheduled.

    John RD asked 12 months ago

    Yes, such an approach is possible. However, the systems that utilize that approach would require significantly more data collectors and antennas, leading to increased costs, particularly with respect to long-term maintenance of the additional assets.

    John RD asked 12 months ago

    Whether or not additional infrastructure could potentially be mounted on the poles or structures proposed for use in this project is a function of the ownership of each and the associated regulations. For instance, at three of the locations, the data collection equipment will be mounted on PSE-owned poles that are replacing existing poles. PSE would have the authority to determine if additional infrastructure would be allowed on their assets. There are two locations where a new pole, to be owned by the City, is proposed to be installed for the sole purpose of this project. There are two additional locations where the data collection equipment will be mounted on existing City-owned infrastructure. The City would only allow additional infrastructure on these assets if such additions are permitted by City regulations.

    John RD asked 12 months ago

    Yes, other existing tall structures were considered by the advanced metering infrastructure system vendor selected by the City.  Ultimately, the seven proposed data collection equipment site locations were selected based on their ability to effectively communicate with water meters across the island while minimizing the amount of infrastructure (i.e., the number of data collectors) required.  The use of other existing tall structures, beyond the Water Reservoir and Island Crest Park locations, either did not provide a benefit in extending network coverage or would be duplicative and therefore not needed.

    John RD asked 12 months ago

    Yes, the City implemented a competitive process to review and select the advanced metering infrastructure system most suitable to meet the City’s needs.  This involved reviewing proposals from a range of vendors who employ a variety of communication technologies.

    John RD asked 12 months ago

    All new structures planned as part of this project are poles, not towers.  In all cases, the structures are lower in height than the threshold (200 feet above ground level) above which consultation with the FAA is required if said structures are to be located in a flight path.  For more information, please reference 14 CFR Part 77.

    Taylor asked about 1 year ago

    As a citywide capital project on the water utility, the cost for all aspects of the water meter replacement project has been factored into Mercer Island water rates.  Water customers will not see any additional charges for the new water meters or monthly charges for their operation.
