Summary:
more-inIf all the mechanical water meters in the city were to be replaced by RFD (Radio Frequency Detection) water meters, the monthly water bill in several residential apartments and commercial establishments would go up by over 50%, a pilot study conducted recently revealed. The RFD meters are more efficient as they do not measure air flow in water pipes that mechanical meters end up measuring quite often. In two months, June and July, on an average, the RFD meters billed 89.15 million litres when compared to mechanical meters that billed 70.41 million litres of water. The Hyderabad Metropolitan Water Supply and Sewerage Board (HMWS&SB) had installed 1,580 RFD water meters in three localities over a period of three months to take the readings. The water board, however, has not set a time-frame for the introduction of RFD meters..
