[미국] AZ타운, 스마트 워터 네트워크로 누수 감소

미국 투손(Tucson)에 위치한 오로밸리 마을은 초기 누수 검사를 통해 물을 아끼고 돈도 절약하고 있다. 또한 스마트 계량기, 소프트웨어, 서비스, 소통 시스템을 제공하는 클린 테크놀로지 회사인 Sensus사의 스마트 워터 네트워크를 설치한 이후로 누수 조정을 57퍼센트나 절감했다고 밝혔다.

Sensus사는 오로밸리 전역에 iPERL 수도 계량기 8천8백 대를 설치했을 뿐만 아니라 FlexNet 커뮤니케이션 네트워크를 설치했다. 도시의 계량기 교체 프로젝트는 2011년에 시작해 1천9백 대의 계량기가 교체되는 2015년 끝마칠 예정이다.

AZ town reduces leak adjustments by 57 percent with smart water network
    
The town of Oro Valley, located north of Tucson, Ariz., is conserving water and saving money through early leak detection and has achieved a 57-percent reduction in leak adjustments since installing a smart water network from Sensus, a clean technology company offering smart meters, software and services and communication systems.

Sensus has installed its FlexNet™ communication network as well as 8,800 of its iPERL™ water meters throughout Oro Valley. The town's meter replacement project began in 2011 and will be completed in 2015 after all of the 19,000 meters have been replaced.

 
To enhance its current conservation efforts, the utility sought a solution that would reduce unaccounted water by increasing meter accuracy and providing early leak detection. The data provided by the Sensus FlexNet communication network facilitates consumer education during water audits, which are offered to customers at no charge.

 
"Manual meter readings are not only time consuming but susceptible to error," said Shirley Seng, water utility administrator at the town of Oro Valley. "Sensus technologies have helped us provide error-free meter readings for our customers resulting in accurate billings, a reduction in paperwork, simplification of billing functions, and significantly improved customer service."

 
The iPERL residential water meters and FlexNet communication network provide two-way communications that feature a sophisticated suite of alarms to better monitor and control water leaks. "Utilities are able to alert customers at the very onset of a leak," said Dan Pinney, director of global water marketing at Sensus. "Customers can also monitor their usage through the utility's customer portal, which helps them keep track of their water use and play an active role in conservation."

 
The Sensus FlexNet system is a long-range radio network that serves as a dedicated and secure two-way communications highway and requires less infrastructure than competing solutions. The network architecture and device designs provide range and endpoint connectivity that is differentiated from mesh networks. The result is superior network performance as evidenced by lower network operational and maintenance costs for utilities.
