Which practice improves the accuracy of water metering and reduces apparent losses?

• A. Increase water pressure to force meters to read more accurately.
• B. Remove metering equipment to simplify system.
• C. Adjust billing to account for errors.
• D. Regularly test and calibrate meters, replace faulty meters, and implement tamper-detection measures.

Answer: (D)

Meter accuracy deteriorates over time due to wear, fouling, and installation effects, so keeping measurement devices trustworthy is essential. Regular testing and calibration align a meter’s registration with actual flow, catching drift before it becomes a bigger error. Replacing meters when they’re out of tolerance prevents consistent misregistration. Adding tamper-detection measures helps uncover unauthorized use or bypass that would create apparent losses. Together, these practices directly improve measurement reliability and reduce losses that show up because meters aren’t accurately recording water. Increasing pressure to force readings can harm meters and distort data; removing meters eliminates measurement altogether; and adjusting billing doesn’t address the underlying measurement errors or detect tampering.
