Your Smart Meter

Smart Meter Technology for All Customers

Our Board of Directors are proud to provide you with the latest tools and technologies to put the power in your hands and provide access to your water information at your convenience.

Through more than $2 million in federal grants received by the U.S. Department of Interior Bureau of Reclamation, Moulton Niguel upgraded your meter technology as part of our “Advanced Metering Infrastructure” (AMI) program to help customers save water and money.

We have completed our smart meter program implementation, which included the installation of approximately 54,600 smart meters. This project is expected to save more than 500 million gallons of water every year!

The upgraded meter technology will help proactively detect water leaks, improve operations, and enable all customers to monitor their hourly water usage through MyWater MNWD, our online customer portal.

smart meter technology

An upgraded radio was installed to your current water meter. Smart water meters collect water use information just as a manually read meter does. The fundamental advantage is they read every hour and transmit those reads wirelessly every few hours.

There are no proven adverse health effects from this system. The radio waves emitted by these devices are a minuscule fraction of what we already experience in the ambient environment from our cell phones, laptops, microwaves, etc. 

These devices are “asleep” up to 99% of the time, “waking up” only to transmit a data point and then turning off again. On average, 99.999% of smart meters transmit for less than one minute per day. 

Numerous industry and independent studies have shown smart meter technology to be very safe. In fact, smart meter devices, at a distance of 10 feet, has only 1/100th of the radio frequency field of that emitted by a laptop computer. Likewise, cell phones, Wi-Fi transmitters and microwave ovens also emit a much greater radio frequency density.
