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

Each public water system that operates a surface water treatment plant to produce drinking water from surface water, or from groundwater that is under the direct influence of surface water, must submit monthly water treatment data to the TCEQ. This page tells system operators how to choose the correct version of the Surface Water Monthly Operating Report (SWMOR).

Report Versions

 There are four versions of the SWMOR. The combined version will replace all previous versions of the SWMOR.

  • Combined SWMOR- this form can be customized for all types of TCEQ approved conventional and alternative surface water treatment technologies. SWMOR Form TCEQ-00105

All plants that use membrane to remove pathogens were to have begun using the Combined SWMOR or the SWMOR-ALT (Rev. 10-01-20) by April 1, 2021. The first month the Combined  or the SWMOR-ALT (Rev. 10-01-20) form is submitted, it must include a completed application/pdfMembrane Plant SWMOR-ALT (Rev. 10-01-20) First Submittal Certification and Verification Form (TCEQ-20889), stating your facility reported the lowest pressure during each DIT and providing verification data.

Alternate Technology Definitions

Alternate technology is defined by the Long Term 2 Surface Water Treatment Rule (LT2)Exit the TCEQ . The LT2 allows systems to receive credit for treatment other than the conventional types (such as coagulation, flocculation, sedimentation, media filtration, and disinfection using chlorine or chloramine).

Under LT2, some groups of plants are required to use alternate technology. Find the group to which your plant is assigned for implementing the LT2 rule by asking for help at LT2@tceq.texas.gov

Alternate 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 alternate technology has a separate worksheet on the SWMOR-Alt.

Chlorine Dioxide Guidance

If you public water system uses chlorine dioxide (CLO2), then you are required to run chlorine dioxide analysis and record the results each day using the Chlorine Dioxide Monthly Operating Report (CLO2 MOR) Microsoft Excel TCEQ Form 00690 and using the application/pdfCLO2 MOR instructions. For more information visit Public Water Systems Using Chlorine Dioxide or Ozone.

SWMOR and SWMOR2 Form Instructions and Guidance, Conventional Systems

The instructions for SWMOR and SWMOR2 are in the TCEQ publication RG-211, Surface Water Treatment Plant Requirements for Monthly Reporting and Public Notification.

See Guidance in RG-379, application/pdfTotal Organic Carbon (TOC) Guidance Manual for testing related to the requirements that must be reported on all versions of the SWMOR.

SWMOR-Alt Form Instructions, Worksheets and Guidance, Alternate Technology

When you first start using the SWMOR-Alt, you need to customize the form to report on the specific technology your plant uses. application/pdfUse these instructions to customize and file your SWMOR-Alt.

Worksheets

All plants that complete the SWMOR-Alt must also fill out the LT2 Summary Worksheet, application/pdfusing these instructions.

Most plants that use alternate technology will use a single type of technology, with unique instructions for completing worksheets for each. Using those instructions (below), you can easily find the information that you need for your specific technology.

  • application/pdfMembrane filtration: The LT2 rule allows credit for removal of Cryptosporidium with membrane filtration.
  • application/pdfAlternate disinfectants: Under the LT2 rule, concentration time credit can be given for inactivating Cryptosporidium with ozone and chlorine dioxide.
  • application/pdfUltraviolet light disinfection: The use of ultraviolet light disinfection is eligible for Cryptosporidium inactivation credit under the LT2 rule.
  • application/pdfPre-filtration: If your plant has pre-filtration technology, you must complete the pre-filtration worksheet in order to receive removal credit.
  • application/pdfBag and cartridge filtration: If your plant uses bag or cartridge filters, there is a worksheet to submit to the TCEQ monthly for Cryptosporidium removal credit.
  • application/pdfEnhanced individual filter effluent (IFE) turbidity: If your plant can achieve consistently low turbidity on all of your media filters, the LT2 allows additional Cryptosporidium removal credit.
  • application/pdfSecond-stage filtration: Second-stage filtration is defined under the LT2 rule as a technology that can achieve Cryptosporidium removal credit.

Total Organic Carbon Guidance

See Guidance in RG-379, application/pdfTotal Organic Carbon (TOC) Guidance Manual for testing related to the requirements for total organic carbon, which must be reported on the SWMOR-Alt for plants that include sedimentation as a unit process.

Surface Water Treatment Violation Report Form

PWS that treat surface water or groundwater under the direct influence of surface water should notify TCEQ when a suspected Treatment Technique, Maximum Contaminant Level, and Maximum Residual Disinfectant Level violation has occurred. 

Surface Water Treatment Violation Report Form (TCEQ 10449) and application/pdfInstructions 

Other Useful Forms and Information 

Surface water treatment plants occasionally need to update their Concentration-Time (CT) studies and to submit additional reports and information when the plant has performance problems. Additional forms, instructions, and guidance for these and other topics can be found on Monitoring and Reporting for Surface Water Systems.

Assistance and Helpful Links

TCEQ's Drinking Water Watch holds the information we have for your public water system and is open to the public. This has contact information, sample sites, sample results, violations, and public notice due dates.

All public notices for the Surface Water Treatment Rule violations can be found at Public Notice Language for Drinking Water Compliance.

TCEQ's Financial, Managerial, and Technical (FMT) Assistance program offers free financial, managerial, and technical assistance to help public water and wastewater systems comply with regulations.
