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 There are 4 treatment component steps of an Aerobic Septic System. The level of the surface of the water in a chamber or basin. A v-shaped opening usually found on one side of a weir. The v-notch provides a means of controlling flow into the weir and separating solids from the final effluent. Anything that isn’t liquid that enters the treatment system. Solids can be trash or sludge. The solids produced by the natural biological treatment process. Activated sludge has an abundance of beneficial microbes (“bugs”) and is used to bolster the aerobic treatment process. The distance from the opening of the treatment system to an adjacent property or structure. Most areas have minimum setback requirements from nearby structures and property. The solids that float on the surface of the water or wastewater. The pipe that conveys water out of a chamber or tank. The process of churning the contents of a chamber or basin. Mixing ensures that solids stay in suspension and the contents of the chamber or basin are uniform in dissolved oxygen, waste-strength and microbes. In many states—and especially Texas—regulators use OSSF instead of “septic system” because it covers all types of on-site wastewater systems, not just traditional tanks. Key points: Governed by state and local health and environmental authorities Requires permits, inspections, and maintenance Must meet public health and groundwater protection standards Conventional (gravity) systems Aerobic treatment units (ATUs) Low-pressure dosing systems Drip irrigation systems A portion of the treatment system that separates solids from the raw wastewater prior to biological treatment. The separation of solids from the wastewater using gravity.

Key points: Governed by state and local health and environmental authorities Requires permits, inspections, and maintenance Must meet public health and groundwater protection standards Conventional (gravity) systems Aerobic treatment units (ATUs) Low-pressure dosing systems Drip irrigation systems Texas OSSF rules (Texas Health & Safety Code, Chapter 366; and 30 TAC Chapter 285) establish minimum statewide standards for: Planning, site evaluation, design, construction, installation, alteration, extension, repair, operation, maintenance, and inspection of septic systems. Licenses and registrations for installers, evaluators, and maintenance providers. Enforcement and permitting procedures where a county or authorized entity administers the program. https://www.tceq.texas.gov/downloads/publications/rg/on-site-sewage-facility-rules-compilation-rg-472.pdf Unless a county adopts its own authorized agent program, the TCEQ itself (through regional staff) is the permitting authority and these statewide rules apply. https://www.tceq.texas.gov/downloads/publications/rg/on-site-sewage-facility-rules-compilation-rg-472.pdf TCEQ rules allow a county or local governmental entity to become an “authorized agent” if it: Passes a formal OSSF regulatory order or ordinance that incorporates TCEQ minimum standards. Holds a public hearing and meets TCEQ criteria. Gets official approval from TCEQ to operate the program within that jurisdiction. https://www.tceq.texas.gov/downloads/publications/rg/on-site-sewage-facility-rules-compilation-rg-472.pdf If a county becomes an authorized agent, it can enforce the state minimum standards plus any locally adopted requirements that are at least as stringent as state law — and it becomes the primary permitting authority rather than the TCEQ regional office. You can confirm whether a specific county has an authorized agent program by contacting the TCEQ or checking county resolutions and public notices (many are not widely published online). https://www.tceq.texas.gov/permitting/ossf/ossf_contacts.html At present, there is no widely published indication that Hardeman, Haskell, Knox, Wilbarger, or Archer County operates its own TCEQ-authorized local OSSF program separate from the statewide default. For most rural Texas counties of similar size and population, this means: TCEQ (via its regional office) is likely the permitting authority, and 30 TAC Chapter 285 and related rules apply directly as the governing standards for septic systems. https://storelocator.homefieldonsite.com/admin/add-question# Local commissioners courts in these counties typically adopt state rules as written rather than establishing separate OSSF programs. Many counties simply enforce the TCEQ rules through the regional office because they do not have the resources to administer a local program. Because the statewide rules govern unless otherwise adopted locally: A. Permitting and Plan Requirements A permit and approved plan are required for construction, repair, alteration, extension, or operation of a septic (OSSF) system unless a qualifying exemption (e.g., the 10-acre rule) applies. Permits may be issued by TCEQ staff or the local authorized agent if one exists. https://www.tceq.texas.gov/downloads/publications/rg/on-site-sewage-facility-rules-compilation-rg-472.pdf B. Site Evaluation and Design A site and soil evaluation, and a system design, must conform to state standards carried out by licensed professionals. Setback and separation requirements from wells, property lines, and water features are established by state rules. https://www.tceq.texas.gov/downloads/publications/rg/on-site-sewage-facility-rules-compilation-rg-472.pdf C. Installation and Maintenance Licensed installers must perform installation (with some exceptions), and maintenance contracts may be required for certain system types. Homeowners must follow state minimum OSSF maintenance obligations. https://www.tceq.texas.gov/downloads/publications/rg/on-site-sewage-facility-rules-compilation-rg-472.pdf D. Enforcement and Compliance The TCEQ regional office or a local authorized agent will handle inspections, approvals, and enforcement actions. Failure to comply with permit conditions or the OSSF rules can lead to orders to repair malfunctioning systems or other enforcement actions under state law. https://www.tceq.texas.gov/downloads/publications/rg/on-site-sewage-facility-rules-compilation-rg-472.pdf Before planning septic work in any of these counties, you should: Contact the TCEQ OSSF program to confirm whether the county is an authorized agent and who the current permitting authority is (TCEQ or local). TCEQ OSSF contacts: ossf@tceq.texas.gov, Phone: 512-239-3799. https://www.tceq.texas.gov/permitting/ossf/ossf_contacts.html Check with the county clerk or commissioners court for local OSSF orders or resolutions adopting state rules as local ordinance. Confirm permitting procedures and fees with the permitting authority identified by TCEQ. Inside city limits, the city is usually the permitting authority, not the county and not directly the TCEQ regional office. Under Texas law, municipalities may act as TCEQ-authorized agents for OSSF regulation within their city boundaries, even when the surrounding county does not administer a local OSSF program . This means: The city may issue OSSF permits The city may conduct inspections The city may adopt stricter standards than the state minimum If public sewer service is available (or reasonably accessible), most Texas cities prohibit new septic systems and require connection to sewer. TCEQ rules allow cities to: Deny septic permits when sewer is available Require abandonment of septic systems upon sewer extension Set distance thresholds (often 100–300 feet) for “availability” . This is the single biggest difference between inside vs. outside city limits. Even though 30 TAC Chapter 285 still applies statewide, cities may adopt ordinances that are more restrictive than TCEQ minimums, including: Larger minimum lot sizes Greater setbacks from property lines or structures Prohibition of certain system types (e.g., spray irrigation) Mandatory aerobic systems instead of conventional systems Enhanced maintenance or inspection requirements TCEQ explicitly allows municipalities to impose stricter requirements once authorized . When a property is inside city limits, the authority order is: City OSSF ordinance or utility department City’s adopted TCEQ-approved OSSF order TCEQ minimum standards (30 TAC Chapter 285) If the city has not adopted an OSSF ordinance: The city still controls sewer availability decisions TCEQ rules apply, but permits may still be routed through the city Cities may require: Additional inspections beyond TCEQ minimums Proof of ongoing maintenance contracts (especially for aerobic systems) Mandatory reporting of failures or alarms Periodic recertification of systems These requirements are city-specific and do not exist uniformly outside city limits . Inside city limits, septic approval is often tied to: Zoning compliance Subdivision plat approval Minimum lot size and density rules Building permit issuance Even if a septic system meets TCEQ design standards, the city can deny approval if the development does not comply with municipal planning rules. Despite local differences, the following do not change: Core design standards still derive from 30 TAC Chapter 285 Licensed installers, designers, and site evaluators are still required Soil and site evaluations are still mandatory Systems must protect groundwater and public health For any of these counties, inside city limits, you should: Confirm sewer availability with the city utility department Identify the city’s OSSF ordinance or permitting authority Verify whether septic is allowed at all Confirm required system type (aerobic vs conventional) Check for stricter setbacks or lot-size rules Obtain city-issued OSSF permit and inspections Coordinate septic approval with building permits A portion of the treatment system that separates solids from the raw wastewater prior to biological treatment. The separation of solids from the wastewater using gravity.

Outside city limits, septic permitting is handled by the local permitting authority (authorized agent) for the property’s county; if there is no local authorized agent, TCEQ becomes the permitting authority. Start here: https://www.tceq.texas.gov/permitting/ossf/ossfpermits.html A permit is generally required for a new system and for most repairs/alterations (e.g., replacing tanks, changing disposal fields, adding lines, relocating components). TCEQ overview: https://www.tceq.texas.gov/permitting/ossf Do not assume “rural = no permit.” Texas has a narrow “permit not required” scenario (e.g., certain single-family situations on larger tracts) that has strict conditions and is not universal—verify with the actual permitting authority first using: https://www.tceq.texas.gov/permitting/ossf/ossfpermits.html Outside-city-limit compliance risks to manage (high frequency): Soil/site constraints (seasonal water table, restrictive layers) driving system type/layout Required separation distances (wells, property lines, structures, drainage features) Flood-prone placement and poor surface drainage planning Use licensed OSSF professionals when required.

Before installing, repairing, replacing, or modifying a septic system, a permit must be obtained from the county’s authorized OSSF permitting authority. Possible Permit Exemptions: Property is 10 acres or larger System serves a single-family residence only No groundwater pollution or surface discharge occurs All system components are at least 100 feet from property lines Effluent remains on the property Foard County administers septic permitting under Texas state authority. Applications, inspections, and compliance reviews are required before system approval. Site Evaluation: Required to determine soil suitability and system sizing Installation: Must be completed by a licensed installer or homeowner for their own residence Maintenance: Conventional tanks should be pumped every 3–5 years. Aerobic systems require routine inspections and service records. Emergency component replacements (such as lids or inlet/outlet devices) do not require a permit but must be reported within 72 hours. County inspectors may conduct site visits. If deficiencies are found, corrections are typically required within 30 days. More information: If your septic system is located inside city limits in Foard County, your system is regulated by the local municipal permitting authority. City permits are required prior to installation or repair Additional local plumbing and setback rules may apply Final inspection approval is required before use State OSSF standards still apply in addition to city codes Cities may impose stricter rules related to lot size, spray irrigation setbacks, and discharge restrictions.

For most rural Texas counties of similar size and population, this means: TCEQ (via its regional office) is likely the permitting authority, and 30 TAC Chapter 285 and related rules apply directly as the governing standards for septic systems. https://storelocator.homefieldonsite.com/admin/add-question# Local commissioners courts in these counties typically adopt state rules as written rather than establishing separate OSSF programs. Many counties simply enforce the TCEQ rules through the regional office because they do not have the resources to administer a local program. Because the statewide rules govern unless otherwise adopted locally: A. Permitting and Plan Requirements A permit and approved plan are required for construction, repair, alteration, extension, or operation of a septic (OSSF) system unless a qualifying exemption (e.g., the 10-acre rule) applies. Permits may be issued by TCEQ staff or the local authorized agent if one exists. https://www.tceq.texas.gov/downloads/publications/rg/on-site-sewage-facility-rules-compilation-rg-472.pdf B. Site Evaluation and Design A site and soil evaluation, and a system design, must conform to state standards carried out by licensed professionals. Setback and separation requirements from wells, property lines, and water features are established by state rules. https://www.tceq.texas.gov/downloads/publications/rg/on-site-sewage-facility-rules-compilation-rg-472.pdf C. Installation and Maintenance Licensed installers must perform installation (with some exceptions), and maintenance contracts may be required for certain system types. Homeowners must follow state minimum OSSF maintenance obligations. https://www.tceq.texas.gov/downloads/publications/rg/on-site-sewage-facility-rules-compilation-rg-472.pdf D. Enforcement and Compliance The TCEQ regional office or a local authorized agent will handle inspections, approvals, and enforcement actions. Failure to comply with permit conditions or the OSSF rules can lead to orders to repair malfunctioning systems or other enforcement actions under state law. https://www.tceq.texas.gov/downloads/publications/rg/on-site-sewage-facility-rules-compilation-rg-472.pdf Before planning septic work in any of these counties, you should: Contact the TCEQ OSSF program to confirm whether the county is an authorized agent and who the current permitting authority is (TCEQ or local). TCEQ OSSF contacts: ossf@tceq.texas.gov, Phone: 512-239-3799. https://www.tceq.texas.gov/permitting/ossf/ossf_contacts.html Check with the county clerk or commissioners court for local OSSF orders or resolutions adopting state rules as local ordinance. Confirm permitting procedures and fees with the permitting authority identified by TCEQ. Inside city limits, the city is usually the permitting authority, not the county and not directly the TCEQ regional office. Under Texas law, municipalities may act as TCEQ-authorized agents for OSSF regulation within their city boundaries, even when the surrounding county does not administer a local OSSF program . This means: The city may issue OSSF permits The city may conduct inspections The city may adopt stricter standards than the state minimum If public sewer service is available (or reasonably accessible), most Texas cities prohibit new septic systems and require connection to sewer. TCEQ rules allow cities to: Deny septic permits when sewer is available Require abandonment of septic systems upon sewer extension Set distance thresholds (often 100–300 feet) for “availability” . This is the single biggest difference between inside vs. outside city limits. Even though 30 TAC Chapter 285 still applies statewide, cities may adopt ordinances that are more restrictive than TCEQ minimums, including: Larger minimum lot sizes Greater setbacks from property lines or structures Prohibition of certain system types (e.g., spray irrigation) Mandatory aerobic systems instead of conventional systems Enhanced maintenance or inspection requirements TCEQ explicitly allows municipalities to impose stricter requirements once authorized . When a property is inside city limits, the authority order is: City OSSF ordinance or utility department City’s adopted TCEQ-approved OSSF order TCEQ minimum standards (30 TAC Chapter 285) If the city has not adopted an OSSF ordinance: The city still controls sewer availability decisions TCEQ rules apply, but permits may still be routed through the city Cities may require: Additional inspections beyond TCEQ minimums Proof of ongoing maintenance contracts (especially for aerobic systems) Mandatory reporting of failures or alarms Periodic recertification of systems These requirements are city-specific and do not exist uniformly outside city limits . Inside city limits, septic approval is often tied to: Zoning compliance Subdivision plat approval Minimum lot size and density rules Building permit issuance Even if a septic system meets TCEQ design standards, the city can deny approval if the development does not comply with municipal planning rules. Despite local differences, the following do not change: Core design standards still derive from 30 TAC Chapter 285 Licensed installers, designers, and site evaluators are still required Soil and site evaluations are still mandatory Systems must protect groundwater and public health For any of these counties, inside city limits, you should: Confirm sewer availability with the city utility department Identify the city’s OSSF ordinance or permitting authority Verify whether septic is allowed at all Confirm required system type (aerobic vs conventional) Check for stricter setbacks or lot-size rules Obtain city-issued OSSF permit and inspections Coordinate septic approval with building permits A portion of the treatment system that separates solids from the raw wastewater prior to biological treatment.

The distance from the opening of the treatment system to an adjacent property or structure. Most areas have minimum setback requirements from nearby structures and property. The solids that float on the surface of the water or wastewater. The pipe that conveys water out of a chamber or tank. The process of churning the contents of a chamber or basin. Mixing ensures that solids stay in suspension and the contents of the chamber or basin are uniform in dissolved oxygen, waste-strength and microbes.
