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

  • Invite representatives from teams involved in water audit data collection. For example, WSO has found it helpful to have staff members from engineering, billing, distribution, and finance on validation calls.
  • Review the supporting document package your agency submitted to WSO and be prepared to discuss.
  • Allot two full hours for the call itself.

What to Expect

  • The call will cover some detailed information about your agency's infrastructure, data handling policies, and instrument maintenance practices.
  • There may be follow-up items that will require you to share additional data or information after the call.
  • Once the requirements of validation have been met, WSO 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).
