Permit holders are required to maintain and operate a flow meter on their wells in order to accurately record their groundwater use on a monthly and annual basis. The resulting information is required to be reported to the EAA no later than January 31 of the following year. Monitoring withdrawals and evaluating monthly meter readings throughout the year can help a user avoid exceeding annual authorized amounts.

A completed Meter Registration Form is required for the installation of new meters. For repairs or replacements, a Meter Replacement Repair Form is needed. When submitting a Meter Registration Form or a Meter Replacement Repair Form that involves installing a new meter on the well, you should attach a copy of the Meter Calibration Certificate with the completed forms. Both forms may be submitted to:

  • Edwards Aquifer Authority
  • Attention: Meter Program
  • 900 E. Quincy
  • San Antonio, Texas 78215

If you need assistance reading your meter or if you believe your meter may not be reading accurately, please contact the EAA's Meter Team at (210) 222-2204 or (800) 292-1047 as soon as possible.

EAA Meter Matters Smartphone App

To better assist Permit Holders to accurately record their monthly and annual use, and to help in meeting reporting requirements, EAA has developed a smartphone application (App) for both iPhone and Android called “Meter Matters.” This App allows well owners to record their meter reading and instantly report that reading to the EAA. The App is free to download and easy to use. When used to report a meter reading during the year, EAA staff can process that submission against the Start-of-Year reading and provide back through the App how much water has been pumped Year-to-Date. This information allows Permit Holders to better monitor and manage their use throughout the year. In addition, EAA staff will use meter readings submitted through the App to populate annual use reports, and if used monthly throughout the year, will fully achieve regulatory reporting requirements.

Once you have downloaded the App to your Smartphone, you can:

  • ADD a meter using the Meter Serial Number (the same number you registered your meter with the EAA)
  • REPORT a Meter Reading to the EAA
  • MANAGE the meters you’ve added to your phone; you can add as many meters as you need. You can also assign a Nickname to your meters for easy reference
  • See a HISTORY of your meter reading submissions. When EAA staff processes your submission, you will see how much water you have pumped through the meter Year-to-Date (YTD)

Reporting a Meter Reading has never been easier!

  • Simply select the meter you which to report
  • Enter your Meter Reading from the Meter Register
  • Take a Photograph of the Meter Register
  • Submit and Confirm the Meter Reading

EAA staff will process your submission and indicate for you how much water has been Pumped Year-to-Date (YTD)
