Forms, Instructions, and Guidance for Surface Water Monthly Operating Reports (SWMOR)

Each public water system that treats surface water or ground water under the influence of surface water, must submit monthly water treatment data to the TCEQ on a customized SWMOR. This page includes the SWMOR and how to complete the form.

Combined SWMOR Excel Form, Instructions, and Total Organic Carbon

NEW Systems must begin using the Combined SWMOR Form TCEQ-00105 as soon as possible but no later than the January 2025 monitoring period due to TCEQ February 10, 2025. The Combined SWMOR replaces all previous versions of the SWMOR. All plants that treat surface water or groundwater under the direct influence of surface water (GUI) must use this new version of the SWMOR, which is an Excel workbook/spreadsheet, to submit their monthly results.

When a membrane plant submits their first Combined SWMOR, it must include a completed Membrane Plant SWMOR-ALT (Rev. 10-01-20) First Submittal Certification and Verification Form (TCEQ-20889). This form states your facility reported the lowest pressure during each direct integrity test (DIT) and must include verification data. If you submitted a Membrane Plant SWMOR-ALT (Rev. 10-01-20) First Submittal Certification and Verification Form with a previous SWMOR-Alt, you do not have to submit it again.

The Combined SWMOR can be customized for all types of TCEQ approved conventional and alternative surface water treatment technologies. All plants that use membranes to remove pathogens must use the Combined SWMOR. Systems that use the SWMOR-ALT (Rev. 10-01-20) must transition to the Combined SWMOR. The Combined SWMOR will replace the SWMOR2, SWMOR-Alt and form numbers 00102-C, 00102-D, 00103, 10276, 10277, and 10278; revision date April 2024. 

Instructions to customize, complete, and submit the Combined SWMOR are in RG-211 Surface Water Treatment Plant Requirements for Monthly Reporting and Public Notification. It is critical that you customize the SWMOR correctly to stay in compliance with the TCEQ requirements. RG-211 also includes instructions to complete filter studies and assessments and other required reports.

Total Organic Carbon (TOC) Guidance

Testing requirements for TOC are in RG-379 Total Organic Carbon (TOC) Guidance Manual. This must be reported in the Combined SWMOR form for plants that include conventional sedimentation or clarification as a unit process.

Alternative Technology - LT2

Alternate technology is defined by the Long Term 2 Surface Water Treatment Rule (LT2) . The LT2 allows systems to receive credit for treatment that is not considered conventional, also called alternative technology. Conventional treatment includes coagulation, flocculation, sedimentation, media filtration, and disinfection using chlorine or chloramine. Under LT2, some treatment plants are required to use alternative technology based on the bin class.

Alternative technologies include membrane filtration, disinfection using ozone or chlorine dioxide, pre-filtration, bag and cartridge filtration, enhanced individual filter-effluent turbidity, and second-stage filtration. Each alternative technology has a separate worksheet in the Combined SWMOR. Although any surface water treatment plant can get permission to use alternative technologies, the LT2 requires certain groups of plants to use at least one of them. Find the group your plant is assigned for implementing the LT2 at LT2 Surface Water Treatment Rule or by emailing LT2@tceq.texas.gov.  

When a membrane plant submits their first Combined SWMOR, it must include a completed Membrane Plant SWMOR-ALT (Rev. 10-01-20) First Submittal Certification and Verification Form (TCEQ-20889). This form states your facility reported the lowest pressure during each direct integrity test (DIT) and must include verification data. Systems must begin using the Combined SWMOR as soon as possible but no later than the January 2025 monitoring period due to TCEQ February 10, 2025. If you submitted a Membrane Plant SWMOR-ALT (Rev. 10-01-20) First Submittal Certification and Verification Form with a previous SWMOR-Alt, you do not have to submit it again.

Worksheets and Guidance for Alternative Technology

All surface water treatment plants that use alternative technology must complete the LT2 Summary worksheet and the worksheet that corresponds to the technology that is used to receive Cryptosporidium inactivation or removal credit from TCEQ. These worksheets are present in your SWMOR. Specific instructions and information for each technology is in the documents below.  

Other Useful Forms and Information

Operating a Surface Water Treatment Plant provides information about requirements that apply to surface water treatment systems and purchase water systems that receive untreated surface water.

PWS that treat surface water or groundwater under the direct influence of surface water (GUI) must notify TCEQ when a suspected Treatment Technique, Maximum Contaminant Level, or Maximum Residual Disinfectant Level violation has occurred using the Surface Water Treatment Violation Report Form (TCEQ 10449) and Instructions.
