Advanced Metering Infrastructure (AMI)

Due to the ongoing Covid-19 pandemic and corresponding economic uncertainty, WSSC Water Commissioners voted today (11/18/2020) to indefinitely defer all activities related to the Advanced Metering Infrastructure project. WSSC Water will continue to closely monitor the economic conditions in both counties and revisit the project at the appropriate time.

WSSC Water is modernizing its operations and technology infrastructure to enhance customer service. A key part of this effort is the Advanced Metering Infrastructure (AMI) project. AMI technology is the foundation of a smart utility, enabling WSSC Water to use the latest technology and data to better serve our customers.

Customers will gain control of their water usage via an information portal. AMI technology improves customer experience by providing access to near real-time water-usage information and helping to quickly recognize potential leaks and other home plumbing issues, which can significantly reduce bills and save money. An additional benefit is a decrease of WSSC Water’s carbon footprint by reducing the number of trucks that we have on the road.

AMI technology allows WSSC Water to better monitor and identify leaks in our system, which helps to prevent large main breaks that can disrupt service to our customers. It will also reduce costs related to meter reading, savings that will be re-allocated to other maintenance priorities.

History of Meter Reading and Benefits of AMI

AMI technology consists of a few components:

  • Water meter – equipment that measures the water used at each location.
  • Encoder register – device attached to the meter that converts water usage into electronic data.
  • Small transmitter – mounted outside a building, this transmitter sends encrypted water usage data back
    to WSSC Water.

AMI technology can connect every part of a water utility and use the resulting data to optimize operations, administration and infrastructure. It allows water meters to communicate water usage information as needed, only four to six times per day. This wireless communication uses radio or cellular technologies.

Customer usage data transmitted to WSSC Water is encrypted using industry standard processes and technologies. No identifiable information, such as name, address, bill account number or credit/collection information, is transmitted to or from the meter.


WSSC Water is an expert in the field of water purification and distribution, as well as the safe treatment of wastewater. We are not experts on the topic of radio frequency emissions, which is why we rely on government agencies entrusted to protect the public health and scientific experts who have studied the topic for decades. Please check out these sites below on the health impacts of radio frequency emissions. We respect that there are differing points of view and we remain opened to listening and fully support additional research on this topic.
