The Portland Water District (PWD) is embarking on a major infrastructure upgrade: replacing nearly all 55,000 water meters across the system with the latest technology in Advanced Metering Infrastructure (AMI). This $30 million investment will roll out over the next three years beginning in October and marks a significant step in enhancing customer service, improving efficiencies, and strengthening leak detection and emergency response capabilities.
The current meter equipment has reached the end of its useful life—the last system-wide replacement took place nearly two decades ago. In 2023, PWD began evaluating the accuracy of the existing meters and meter reading system. The review revealed increased wear and aging of metering equipment, prompting a thorough needs assessment and technology evaluation in collaboration with an industry consultant. AMI emerged as the long-term solution, employing the latest technology in meter systems to support modern operations and evolving customer expectations.
To implement this upgrade, PWD has partnered with Core & Main to deliver a complete AMI solution, featuring Sensus (non-mechanical) water meters and VEPO Metering for professional installation services. The installer will contact customers directly to schedule appointments, beginning in Gorham and progressing through the service area. There are no additional out-of-pocket costs for installation or meter equipment, the cost is factored into rates.
“This project impacts every customer since meters are located inside homes and businesses,” said Scott Firmin, General Manager at the Portland Water District. “We selected a contractor with a strong track record of customer service and safety.” All installers will carry identification, wear uniforms, and drive clearly marked vehicles. Customers can request an electronic photo ID notification of the technician prior to the appointment.
The new AMI system will provide a secure and reliable method of collecting water consumption data via a secure FlexNet communication network. This technology will allow for streamlined billing, improved leak detection, operational efficiencies, and improved customer service.
In addition to operational improvements, customers will benefit from a new online portal that allows easy access to billing, usage data, and conservation programs—putting more information and control directly into the hands of the customer. The portal will be launched later in the project.
This project reflects PWD’s ongoing commitment to investing in innovative, customer-focused infrastructure that meets the current and future needs of the Greater Portland region.
