As the water meters of the city of Tyler, Texas (83,700), aged, they became more inaccurate, almost always in the customer’s favor. As a result, the city was losing approximately $2.2 million a year in reduced water revenue. The city decided to replace its water meters with units that transmit information with radio signals. Additional revenues from these much more accurate units are being used to replace the utility’s heating, ventilation, and air conditioning units and install energy efficient lighting in the city facilities and in traffic signals.
