An aerobic septic system in Ellis County, Texas, is an on-site sewage facility (OSSF) designed to treat and dispose of wastewater using aerobic (oxygen-loving) bacteria. These systems are often used in areas where traditional septic systems are not feasible due to soil conditions, space limitations, or environmental concerns. 

Maintenance reports for aerobic systems must be submitted by licensed providers and submitted in a timely manner. Homeowners should maintain records of maintenance, pumping and repair activities. Further requirements for an outside cities can be found in other FAQs for that city.

The system introduces air into the wastewater treatment process to promote the growth of aerobic bacteria, which break down organic matter more effectively than anaerobic bacteria used in conventional systems

The system design must comply with TCEQ Chapter 285 regulations. Some cities may impose additional rules, stricter setbacks and enhanced treatment standards or addtional inspections. Follow your specific city guidelines along with those in the TCEQ Chapter 285 regulations. 
Types of systems permitted depend on soil conditions, property size, and usage. These include:
Conventional septic systems.
Aerobic treatment units.
Low-pressure dosing systems.
Systems must accommodate the expected wastewater flow and soil absorption rate. More information can be found by contacting the Ellis County Department of Development (DOD) at 109 S. Jackson St., Waxahachie, TX 75165 Phone 972-825-5200

There are 4 treatment component steps of an Aerobic Septic System. 

• The Pretreatment Tank is the initial tank where solids settle, similar to a conventional septic tank.
•  The next treatment step is where air is introduced to the wastewater to promote aerobic bacterial activity.
•  The third step is the disinfection step. This is where treated water is disinfected using chlorine, Ultraviolet light or other methods. 
• The final step is where the treated water is either dispersed throughout a surface (spray irrigation ) or a subsurface drain field

Setbacks: Systems must meet distance requirements from property lines, water wells, and surface water. See city specifc questions for more detail. 
Floodplains: Additional regulations may apply if the property is in a floodplain.
Variances: May be required for non-standard installations or properties with unique conditions. Routine pumping and maintenance are the homeowner's responsibility. Keep records of pumping and any repairs. Aerobic Systems must have a continuous maintenance contract with a licensed provide. Maintenance providers are required to submit inspection reports to the permitting authority.

The class of soil required for an aerobic septic system (commonly called an aerobic treatment unit, or ATU) depends on its ability to handle treated wastewater effectively. Aerobic systems are often used when soil conditions are not suitable for conventional septic systems. Here's an overview of soil considerations for aerobic systems:                                                                                                                                                                                          Soil Requirements for an Aerobic System  

• Soil Classification:
  • Soils are generally categorized into different classes based on their texture, permeability, and ability to absorb water. The most favorable soils for an aerobic system include Class I and Class II soils, which typically have good drainage characteristics.
  • Class III soils, which are heavier (like clay), can be used if properly managed, but they may require additional design considerations.
  • Class IV soils (e.g., very dense clays) are typically unsuitable for septic systems, but aerobic systems can sometimes be installed with enhanced dispersal methods like drip irrigation or spray distribution.

The class of soil required for an aerobic septic system (commonly called an aerobic treatment unit, or ATU) depends on its ability to handle treated wastewater effectively. Aerobic systems are often used when soil conditions are not suitable for conventional septic systems. Here's an overview of soil considerations for aerobic systems:                                                                                                                                                                                          Soil Requirements for an Aerobic System  

• Soil Classification:
  • Soils are generally categorized into different classes based on their texture, permeability, and ability to absorb water. The most favorable soils for an aerobic system include Class I and Class II soils, which typically have good drainage characteristics.
  • Class III soils, which are heavier (like clay), can be used if properly managed, but they may require additional design considerations.
  • Class IV soils (e.g., very dense clays) are typically unsuitable for septic systems, but aerobic systems can sometimes be installed with enhanced dispersal methods like drip irrigation or spray distribution.

All septic systems, regardless of location, must comply with the Texas Commission on Environmental Quality (TCEQ) standards. The Ellis County Department of Development (DoD) oversees permitting for on-site sewage facilities (OSSFs), but additional requirements may apply within city limits. You have to determine the regulatory authority for your city. Inside city limits, the city may have its own permitting process in addition to Ellis County’s requirements. Obtain an application from the Ellis County Department of Development or the city (if applicable). It must include a site evaluation and soil test conducted by a licensed professional. A system design prepared by a licensed engineer along with a property plat or site plan showing the setback and system layouts. 

 For properties located inside city limits in Ellis County, Texas, septic maintenance and operation requirements are primarily guided by Texas Commission on Environmental Quality (TCEQ) regulations, but additional rules may apply depending on the specific city’s ordinances. See city specific FAQs for further detail. We recommend that you contact your cities permitting office for detailed information. In summary, conventional septic systems should have the tanks pumped every 3-5 years to prenent sludge build up and system failure. Regular inspections will be required by a licesnes provider. Any repairs must meet the TCEQ standards and may require city approval. for Aerobic Treatment Units you will need maintenance contracts by a licensed provider. A contract should include periodic inspections, testing and maintenance 3 times per years or as required by your city permit. Systems using chlorine disinfection must have chlorine tablets replenished regularly with septic-safe chlorine products.

An aerobic septic system in Ellis County, Texas, is an on-site sewage facility (OSSF) designed to treat and dispose of wastewater using aerobic (oxygen-loving) bacteria. These systems are often used in areas where traditional septic systems are not feasible due to soil conditions, space limitations, or environmental concerns. 

Maintenance reports for aerobic systems must be submitted by licensed providers and submitted in a timely manner. Homeowners should maintain records of maintenance, pumping and repair activities. Further requirements for an outside cities can be found in other FAQs for that city.

The system introduces air into the wastewater treatment process to promote the growth of aerobic bacteria, which break down organic matter more effectively than anaerobic bacteria used in conventional systems

The system design must comply with TCEQ Chapter 285 regulations. Some cities may impose additional rules, stricter setbacks and enhanced treatment standards or addtional inspections. Follow your specific city guidelines along with those in the TCEQ Chapter 285 regulations. 
Types of systems permitted depend on soil conditions, property size, and usage. These include:
Conventional septic systems.
Aerobic treatment units.
Low-pressure dosing systems.
Systems must accommodate the expected wastewater flow and soil absorption rate. More information can be found by contacting the Ellis County Department of Development (DOD) at 109 S. Jackson St., Waxahachie, TX 75165 Phone 972-825-5200

There are 4 treatment component steps of an Aerobic Septic System. 

• The Pretreatment Tank is the initial tank where solids settle, similar to a conventional septic tank.
•  The next treatment step is where air is introduced to the wastewater to promote aerobic bacterial activity.
•  The third step is the disinfection step. This is where treated water is disinfected using chlorine, Ultraviolet light or other methods. 
• The final step is where the treated water is either dispersed throughout a surface (spray irrigation ) or a subsurface drain field
