AMI (Advanced Metering Infrastructure) is the latest in metering technology used by water agencies across the United States and internationally to provide more accurate, up-to-the-moment water use information.
In contrast to MMWD’s standard meters which are typically read every two months, AMI systems automatically provide more frequent reads. This enhances our ability to detect leaks and provide customer support, while also making it easier for customers to manage their water use and their water bill. AMI can also help protect water quality by detecting reverse flows on a water meter and alerting district staff of potential backflow contamination.
MMWD’s AMI Pilot Project—funded by a $975,000 grant from the California Department of Water Resources—is installing AMI endpoints in two phases. The first phase covers about 800 dedicated irrigation meters throughout our service area. These are primarily large landscape customers (parks, golf courses, HOAs, schools, businesses) who can benefit from being able to easily monitor irrigation water use at multiple locations.
The second phase of the project includes about 1,200 select households in the Tiburon-Belvedere area. This area was chosen for the pilot because it offers a good mix of concentrated customers and topography to allow us to evaluate the benefits of AMI for residential customers.
For the pilot project, we selected neighborhoods based on a variety of factors including topography, water pressure zones, distribution system age and potential for leaks, and landscape size. By including a cross section of different neighborhoods in the pilot project, we’ll be better able to evaluate the benefits of AMI for our customers.
No, there is no charge for the AMI technology.
In most cases, the AMI endpoint is installed onto an existing water meter. This generally takes less than 30 minutes and there is no disruption to service.
Yes, AMI is as safe as cell phones, laptops, bluetooth devices and similar equipment. The AMI technology MMWD is installing transmits water use data once per day via cellular signal from your water meter box. The signal strength is equivalent to sending a text message.
Yes, the data transmitted from your meter is encrypted and includes only meter flow information. No billing or personal information is transmitted.
