Mayor Tom Lowry and members of the Three Rivers City Commission have authorized an upgrade of residential water meters. City officials estimate more than 1,300 meters will be upgraded in order to make it easier to read water meters and quickly identify leaks. Between installation and materials, the measure will cost just under $330,000. The city has been budgeting for the expenditure since 2011. The new units, which can be read by radio transmission, will be installed by early 2014.
