There are three versions of the SWMOR.
- Conventional Plants that use sedimentation and media filtration, with no innovative or alternate technology, are considered to use “conventional” treatment and should use the SWMOR, Form TCEQ-00102C .
Plants that produce less than 10,000 gallons per day (gpd) should use SWMOR-gpm .
- Conventional Plants with Only Two Filters that use “conventional” treatment (sedimentation and media filtration), with no innovative or alternate technology, must use the SWMOR2, Form TCEQ-00103 .
Plants that produce less than 10,000 gpd should use SWMOR2-gpm .
- SWTPs Using Alternate Technology must submit the SWMOR-Alt, Form TCEQ-00102D , along with the worksheets related to the specific technology completed (see below under "Form Instructions and Guidance, Alternate Technology).
Plants that produce less than 10,000 gpd should use SWMOR-Alt-gpm .
Starting July 1, 2013, systems that use membrane filters must complete the SWMOR-Alt. Later, systems using other alternative technology will be required to complete the SWMOR-Alt to receive credit for pathogen inactivation or removal.
Alternate Technology Definitions
Alternate technology is defined by the Long Term 2 Surface Water Treatment Rule (LT2) . 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.
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 Disinfection Guidance
Each public water system that uses chlorine dioxide (ClO2) disinfectant will need to run special ClO2 tests and record the results each day. Complete the required Chlorine Dioxide Monthly Operating Report (CLO2MOR), TCEQ Form 00690 to record the ClO2 test results using these CLO2MOR instructions .

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. Use these instructions to customize and file your SWMOR-Alt .
All plants that complete the SWMOR-Alt must also fill out the LT2 Summary Worksheet, using 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.
- Membrane filtration : The LT2 rule allows credit for removal of Cryptosporidium with membrane filtration.
- Alternate disinfectants : Under the LT2 rule, concentration time credit can be given for inactivating Cryptosporidium with ozone and chlorine dioxide.
- Ultraviolet light disinfection : The use of ultraviolet light disinfection is eligible for Cryptosporidium inactivation credit under the LT2 rule.
- Pre-filtration : If your plant has pre-filtration technology, you must complete the pre-filtration worksheet in order to receive removal credit.
- Bag 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.
- Enhanced 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.
- Second-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, Total 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.
Other Useful Forms and Information for Surface Water Treatment Plants
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.
