There are over 8,000 acoustic, leak-detecting sensors installed on hydrants in San Jose Water’s distribution system. The initial deployment of 2,000 of these sensors used 3G to communicate changes in acoustic noise — signifying a potential leak. As all cell carriers are phasing out 3G by the end of 2022, SJW proactively replaced these with newer, 4G nodes this year. However, disposing of 2,000 sensors had to be done carefully and thoughtfully.
