Town of Arlington to Deploy Itron’s Advanced Metering System, Water SaveSource™

LIBERTY LAKE, Wash. — February 23, 2010 — Itron Inc. (NASDAQ: ITRI) announced today that it has signed an agreement with the Town of Arlington, Mass., (Arlington) to install Itron’s advanced metering system, Water SaveSource. Located six miles northwest of Boston, Arlington provides water service to approximately 43,000 residents.

By deploying Water SaveSource, Arlington is moving beyond collecting meter reads for just monthly billing purposes. Being able to collect incremental meter reads, or data logging, Arlington will better understand its customers’ water usage. With this information, they can enhance customer service with off-cycle meter reads and faster bill reconciliation. Access to such granular data will also support water conservation efforts, tracking of unaccounted for water loss and proactive in-home leak detection programs.

The Massachusetts Water Resources Authority (MWRA) provides wholesale water and sewer services to Arlington and is working with its member communities to increase water conservation and minimize waste water flows.

“Arlington is excited to be working with Itron,” said Michael Rademacher, Town Engineer of Arlington. “Installation of their water meter reading and monitoring system will give us the tools to better manage usage and reduce water losses. The system is key to helping us lower consumption to meet our goals.”

After Water SaveSource is deployed to approximately 12,500 customers, Arlington will benefit from the system’s two-way capability via time-synchronized meter data and be able to interrogate the meter without mobilizing personnel.

“As a new customer to Itron, we are excited about Arlington’s commitment to active water management through the meter,” said Lou Gust, vice president of water sales and marketing for Itron. “Their focus on water conservation and helping to extend the life of existing infrastructure while decreasing the need for additional water resources is to be commended and we are very pleased to be their partner of choice.”
