Meter Accuracy Verification
EAA permit holders authorized to withdraw more than 28 acre-feet of groundwater annually are required to perform an accuracy verification on their meter(s). Any meter not achieving a certified (+/-) 5% error rate cannot be used and must be either repaired, replaced or calibrated.
Tamper Detection Devices
The tamper detection devices used by the EAA consist of a simple thin wire or cable measuring from 13”- 39” in length. These cables contain a barcode and are numbered for tracking purposes. In some situations, the configuration your meter installation may require the use of a different form of tamper detection device to accommodate your meter(s). As outlined in the EAA rules (PDF), tamper detection devices “may not hinder the day-to-day maintenance or emergency repairs of the pipe upon which the meter is installed and shall be consistent with state and federal regulations.” If a permit holder encounters an issue with a meter, they may remove the device. If such action is required, the permit holder should immediately contact the EAA Meter Team and report the incident.
