Sewer Overflow and Bypass Reporting: NeT-SEWEROVERFLOW

Find out how to submit sanitary sewer overflow and bypass data to TCEQ for your Texas Pollutant Discharge Elimination System (TPDES) permit.

Disclaimer: Access to the EPA's Net-SewerOverflow tool is limited. Publicly owned treatment works participating in a pilot program will be able to use it in a "test" environment. 

Submitting Your Report Electronically

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

Access the NeT-SEWEROVERFLOW Tool at EPA’s Central Data Exchange (CDX).

Request an Electronic Reporting Waiver - If you cannot submit your report electronically as required, submit a Request for Electronic Reporting Waiver form (TCEQ-20754).

Roles and Signatory Authority

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 Sanitary Sewer Overflow training. 

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