San Francisco PUC chooses AMI system

San Francisco, CA and Cleveland, OH, U.S.A. — (METERING.COM) — November 26, 2009 – The San Francisco Public Utilities Commission (SFPUC) will begin citywide installation of the Aclara STAR® Network system in early 2010, the company has announced.

The SFPUC, with 170,000 retail customer accounts, will be the first major California water utility to install advanced metering infrastructure (AMI) technology to track water consumption.

The new system will send hourly consumption data to the SFPUC four times daily. Currently, most residential water meters in San Francisco are read once every two months and commercial meters are read monthly, with meter readers required to individually visit and read each meter manually. This labor intensive and infrequent process makes it difficult to detect silent leaks, which can result in significant water loss and high water/sewer bills for customers.

“With California facing long term threats to our water supplies and natural resources from climate change and population growth, literally every drop of water counts,” said SFPUC general manager Ed Harrington. “Automated meters will give the SFPUC and our customers more accurate information about water consumption that will help us detect leaks faster and conserve more.”

Data from the STAR Network system will allow SFPUC staff to immediately flag surges in water consumption and detect possible leaks. Eventually, customers will be able to log on to their own accounts with the SFPUC to monitor their own water consumption habits and billing.
