Around the State-CentralHAMILTON Aqua New Jersey doesn?t want to send out crowds of meter readers any more. Instead it?s spending $1.5 million to install 14,000 new devices at homes in central and southern New Jersey that can be read on the fly. ?We can take readings simply by driving by the property, which improves our efficiency by significantly increasing the number of meters we can read in a day,? says Ed Rapciewizc, vice president of the water utility. The installation will remove a homeowner?s existing hardware and replace it with a new radio transmitter. The work should be done by November.
