Advanced Metering Infrastructure (AMI)

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.

Although most capital projects do not have a measurable return on investment, based on previous studies, the implementation of Advanced Metering is projected to pay for itself in six to seven years.

How does Advanced Metering Infrastructure work?

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 radio or cellular transmitter - typically 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.
