Keeping Meters On Line: Accurately Measuring Drinking Water and Sewage
Water Engineering & Management
September 2002
Rodney Johnson
Detroit Water & Sewerage Department (DWSD) has a high stake in keeping its flowmeters up and running with calibrated accuracy. This is especially true for its 278 wholesale water meters used in its vast network of distribution lines that serve 126 communities. It also is true for metering sewage inputs from wholesale customers for its Wastewater Treatment Plant. This article focuses on a unique answer that DWSD found for keeping its magnetic meters online by means of a portable electronic system that verifies and certifies calibration, all done in-line.

Texas Utility Cuts Meter Reading Costs, Improves Efficiency with AMR
Water & Wastes Digest
April 2002
The city of Pasadena, Texas, targeted a variety of objectives for improved customer service in meter reading. Pasadena’s primary goals were elimination of estimated water bills and minimized disruption for customers. But the city’s manual reading system was inefficient, especially where meters were remote or hard to access. The answer was a system that increased the efficiency of Pasadena’s water meter reading operations with a leap from a manual meter reading process to an automated meter reading (AMR) solution.
