Users of a water purveyor's submission portal can make changes to gauge records, which includes basic information such as the manufacturer, model and serial number. Users can also upload a gauge's calibration documentation, and update the gauge's calibration date and calibration expiration date. Although a user can update a gauge's calibration information, the water purveyor still needs to review and approve any changes.

1. Select Administration from the navigation menu, and then select External Gauges.

2. In the Changes Pending Review section, click Review Docs.

3. Review the updates made to this gauge, including the gauge's calibration documentation, which can be accessed by clicking the View button at the top of the page.

4. When you're finished making changes, click Update and Approve at the bottom of the page.
