NeT Sewer Overflow: Electronic Reporting Deadline and Pilot Program

This webpage gives an update on the electronic reporting deadline for unauthorized discharges and unanticipated bypasses and provides resources to help facilities participating in the NeT Sewer Overflow Pilot Program.

Electronic Reporting Deadline

TCEQ sent letters in December 2023 extending the e-reporting deadline for unauthorized discharges and unanticipated bypasses until December 21, 2025. Permitted facilities should continue reporting unauthorized discharges, sanitary sewer overflows, and bypasses using the Noncompliance Notification form ( TCEQ-00501) until the e-reporting deadline of December 21, 2025.

NeT-Sewer Overflow Access and Pilot Program

Access to EPA's NeT-Sewer Overflow Test tool is currently limited to a few publicly owned treatment works (POTWs) participating in a pilot program. Pilot program participants are testing the tool and will provide feedback to TCEQ.

Once the pilot program is complete and the tool is ready for broader use, TCEQ will contact impacted POTWs with information on how to access and use the tool.

Submitting Your Report Electronically–Pilot Facilities Only

Submit TPDES sanitary sewer overflow and bypass reports through EPA’s National Pollutant Discharge Elimination System eReporting tool for Sanitary Sewer Overflows and Bypasses (“NeT-Sewer Overflow”). 

Access the NeT-Sewer Overflow test tool using the link provided by TCEQ.

Roles and Signatory Authority–Pilot Facilities Only

Understand Your Role

  • Signatory: Can sign, submit, manage, prepare, and edit all forms.
  • Preparer: Can prepare all forms on behalf of the signatory at the facility but cannot sign or submit the report. Find out how to submit your report to a signatory on slide no. 9 of the NeT-Sewer Overflow training .

Request Access to Your Facility - Once you have access to NeT-Sewer Overflow, someone with the signatory role must request access to your facility's records. Then they can grant others access to the facility information.
