Validation session
To make sure your validation session goes as smoothly as possible, here’s some information about how to prepare and what to expect.
| How to prepare | What to expect |
|---|---|
| Invite representatives from teams involved in water audit data collection. We find it helpful to have staff members from departments like engineering, billing, distribution, and finance on validation calls. | The call will cover some detailed information about your agency’s infrastructure, data-handling policies, and instrument maintenance practices. |
| Review the supporting document package your agency submitted to our water loss consulting team and be prepared to discuss. | There may be follow-up items that will require you to share additional data or information after the call. |
| Allot two full hours for the call itself. | Once the requirements of validation have been met, our team will return a validated water audit, a validation certificate, detailed notes from the call, and directions for submitting materials to the Department of Water Resources (DWR). |
