Advanced Metering Infrastructure

frequently asked questions

Smart meters are water meters that offer two-way communications between the meter at your home or business and MAWSS. They are a key component of our new Advanced Metering Infrastructure (AMI) system.

Either MAWSS employees or a MAWSS approved contractor will replace the existing meter with a new AMI Smart Meter. You will notice a small raised antenna on the top of your meter box once your meter has been replaced.

The meters are tested by the manufacturer and comply with the American Water Works Association (AWWA) standards. If you feel that your meter reading is inaccurate, contact MAWSS customer service at 251-694-3100 or email

Water meters are outfitted with a radio transmitter that send usage data to a network of collectors which transmit the data back to the MAWSS offices.

The life expectancy of the devices installed in the field is 20 years. Periodic inspection and maintenance will be performed to ensure all devices are performing as expected.

The new meters will not negatively affect your health. The wireless portions of the system will be operated per Federal Communications Commission rules, and will not interfere with other radio frequencies in the area. The transmitters use one-quarter of the power of a cellphone transmission. Exposure to radio waves from smart meters is tiny compared to cellphones transmissions. The amount of exposure to radio waves decreases with the square of the distance from the radio source and the total transmission time is only 15 second per day.
