Water delivery and metering in West Haven is about to get more sophisticated, according to the water company.

About 13,000 South Central Connecticut Regional Water Authority customers in West Haven are about to get the water industry’s latest metering technology installed beginning next month, the RWA said in a news release.

The West Haven customers will join about 50,000 customers in the RWA’s water district who already have received the upgrade.

The system will allow the authority to accurately read customers’ water meters by securely transmitting a low-powered signal from an advanced metering infrastructure, or AMI, endpoint (a small device connected to the meter) to the RWA’s office.

Installation of the new technology will upgrade how the water authority receives water consumption information, the RWA said.

It also will eliminate the need for manually reading customers’ meters, provide early detection of water leaks and largely eliminate estimated water bills, the authority said.

Over the next two years, the water authority will deploy the new metering system to every customer in its 15-town service area, the release said.

Crews will be working in West Haven installing the AMI technology between now and the end of the year, said RWA spokesman Dan Doyle.

“In about 70 percent of the cases, customers will have an older meter” and replacing it with the AMI should take about 30 minutes, during which the customer’s water will have to be turned off, Doyle said.

The new technology “allows us to identify” water usage issues “weeks earlier,” he said.

“In the long term, this is going to be a great benefit to our customers,” Doyle said.

The RWA, which Doyle said is the first water utility in Connecticut to employ AMI technology, hired Contract Callers Inc., or CCI, to install the new advanced meter reading devices.

Installation involves attaching the AMI endpoint to the customer’s existing water meter, usually where the existing meter reading device is located, the release said.

In some cases, the RWA may need to install a new water meter to ensure compatibility with the device. There is no cost for the new meter reading device or the installation.

Customers should receive a letter and a flyer that explains what to expect. Information about the program is also located on the RWA’s website at www.rwater.com/AMI.

For customers’ safety, all RWA and CCI personnel have identification badges. CCI installers wear blue uniforms with a CCI logo. They carry two forms of photo identification: an RWA contractor badge and a CCI badge.

The contractor’s vehicles are white and have CCI and RWA logos on both sides.

The RWA encourages customers to always ask for identification from anyone who comes to their door and to maintain a “no identification — no entry” policy, the release said

Customers can call the RWA at 203-562-4020 to verify that installers are working in their neighborhood. CCI also will register installation activities with local police departments and the RWA Police Department.

The South Central Connecticut Regional Water Authority provides water and services to almost 430,000 people in 15 cities and towns throughout Greater New Haven.

The RWA owns, maintains and protects more than 27,000 acres of watershed land. For more information on the RWA, visit www.rwater.com.
