The State Water Resources Control Board posted step‑by‑step instructions for sanitary sewer system enrollees to submit internal audit reports into the California Integrated Water Quality System (CWICS).

The guidance says enrollees must submit internal audit reports within six months of the end of the audit period and that the agency’s specific due date appears on the internal audit report page in CWICS. Presenter guidance emphasized that providing a late‑filing justification does not exempt an enrollee from filing the audit report and that delayed reports must still be uploaded and future audits must follow the original schedule.

The board’s instructions require that the legally responsible official (LRO) for the agency perform the submission. To log in, users must have their CWICS username and password plus the WDID, account PIN and security question answers associated with their account; the guidance directs users to seawics.waterboards.ca.gov and to contact the CWICS help center if they lack credentials.

From the CWICS home page, the presenter walked viewers through navigation: click the Sanitary Sewer Systems link, select the appropriate system (the portal permits certifying only one system at a time), then open the Internal Audit Report upload link and the Submit/Certify option (available only for audit periods that have ended). Uploaded files must be Word or PDF format, the document date should be the date the document was finalized, and the file size may not exceed 75 megabytes; zipped files are not accepted.

The guidance explains how to add supplemental audit documents (attachments, photos, tables or appendices) by using the Add New Row function and selecting "Other" as the document type. For certification, the LRO must review each certification statement, check the boxes, enter the password and click certify; the system displays a confirmation message and sends a confirmation email to the LRO and related data submitters.

If an audit cannot be submitted by the due date, CWICS users should select "Provide Justification for Not Submitting the Audit Report by Due Date" on the Audit Report Certification page and enter a valid reason (the presenter gave examples such as sudden departure of an LRO or a cyber attack). The guidance instructs enrollees to save the justification and, when able, follow the regular upload and certify process to submit the delayed audit report.

For questions not covered by the video, the board directed users to contact State Water Resources Control Board sanitary sewer staff at sanitarysewer@waterboards.ca.gov and to consult additional training videos under the General Order Compliance Tools tab on the State Water Resources Control Board website. The video credits Summit Partners and lists several water‑agency partners and the producer Ridgecresta Learning and Development Services.

The instructions clarify administrative and technical steps for compliance; agencies that remain unsure of their CWICS credentials or the proper LRO should contact the board’s sanitary sewer staff for assistance.
