How Much Land Sq Ft In Texas To Have Septic Tank? (Correct answer)

If a drinking water system is on the property, the minimum lot size for a septic tank consideration is 20,000 square feet provided percolation is satisfactory.

Texas Administrative Code.



  • A septic tank should not be considered if the lot size is under 15,000 square feet. If a drinking water system is on the property, the minimum lot size for a septic tank consideration is 20,000 square feet provided percolation is satisfactory. (4) Individual sewer connections.

How much land is needed for a septic system in Texas?

Yes, Texas State Law requires a ½-acre lot with a public water supply connection as a minimum. ANRA can issue a variance to this rule if all setbacks on the septic system design have been met. Requirements may vary by county.

How many septic tanks can you have per acre in Texas?

(Q) How many houses can I put on my property with septic? (A) You may have one single family dwelling per acre that utilize public water supply and on-site sewage facilities. Where a private water supply is used and on-site sewage facilities, you must maintain one single family dwelling per one and a half acres.

How much land is needed for a leach field?

A minimum lot size of one-half acre (average gross) per dwelling unit is required for new developments in the Region using on-site septic tank-subsurface leaching/percolation systems.

Can I install my own septic tank in Texas?

It is legal under Texas law to install your own septic tank. However, certain systems cannot be sold to property owners individually and must be sold to factory representatives. Exceptions to this rule are licensed electricians and the person who delivers the tank or septic system to the installation site.

How much does it cost to put in a septic system in Texas?

Installation of a septic system costs between $2,800 and $8,000 with an average of $5,000. Between $5,000 and $22,500 is the range for total expenses for well and septic system drilling and installation.

How big of a septic tank do I need for a 3 bedroom house?

The correct size of the septic tank depends mostly on the square footage of the house and the number of people living there. Most residential septic tanks range in size from 750 gallons to 1,250 gallons. An average 3-bedroom home, less than 2500 square feet will probably require a 1000 gallon tank.

Can a septic tank be too big?

A septic tank that is too big will not run well without the proper volume of wastewater running through it. If your septic tank is too big for your house, there wouldn’t be sufficient collected liquid required to produce the bacteria, which helps break down the solid waste in the septic tank.

How do I calculate the size of my septic drain field?

Drainfield Size

  1. The size of the drainfield is based on the number of bedrooms and soil characteristics, and is given as square feet.
  2. For example, the minimum required for a three bedroom house with a mid range percolation rate of 25 minutes per inch is 750 square feet.

Are septic tanks still legal?

Septic Tanks Explained… Septic tanks cannot discharge to surface water drains, rivers, canals, ditches, streams or any other type of waterway. you are required to upgrade or replace your septic tank treatment system to a full sewage treatment plant by 2020, or when you sell a property, if it’s prior to this date.

What are the new rules on septic tanks?

According to new regulations passed in 2015, if your septic tank discharges to surface water such as a ditch, stream, canal or river, you will have to upgrade your system to a sewage treatment plant or install a soakaway system by 1 January 2020.

Can you have a septic tank without a leach field?

The waste from most septic tanks flows to a soakaway system or a drainage field. If your septic tank doesn’t have a drainage field or soakaway system, the waste water will instead flow through a sealed pipe and empty straight into a ditch or a local water course.

How far should drain field be from septic tank?

Common guidelines require at least 50′ clearance distance between a well and a septic system tank or 150′ between a well and a septic drainfield or leaching bed but you will see that different authorities may recommend different distances. Local soil and rock conditions can make these “rules of thumb” unreliable.

How deep is a typical leach field?

A standard leach line is considered to be three (3) feet wide and three (3) feet deep with a length as required.

How far should leach field be from house?

Local codes and regulations that stipulate the distance of the septic tank from the house vary depending on the locale, but the typical minimum distance is 10 feet.

Basics for Septic Systems

On-site sewage facilities, also known as OSSFs, must be developed on the basis of a site evaluation that takes into consideration the specific requirements of the location. The system of choice for around 20% of new homes being built in Texas is the radon mitigation system. An On-Site Sewage Facility (OSSF), sometimes known as a “septic system,” is a sewage treatment system that is located on a property. As a result of the unexpected surge in new housing construction in suburban and rural regions, more Texas families are reliant on an OSSF for the treatment and disposal of their domestic sewage.

Systems that accomplish their jobs well while also protecting the environment are made possible by new methods to design and oversight of OSSFs.

A number of soil tests are ruling out traditional systems, which separate liquids from solid waste in a holding tank and then distribute them throughout a drainfield using underground pipes or other proprietary items in many regions of the state.

However, because the majority of Texas soils are incapable of adequately absorbing contaminants, different treatment procedures are necessary.

Any work on an OSSF must be done by a licensed installer or, in the case of a single-family property, by the homeowner himself or herself.

Who checks to make sure the requirements are followed?

Local governments in most parts of the state have taken on the obligation of ensuring that OSSFs in their jurisdictions comply with all applicable state regulations and procedures. There are several local governments that serve as “authorized agents” (AA) of the Texas Commission on Environmental Quality, which is in charge of managing the OSSF Program. A “designated representative” (DR) assists the AA in carrying out their tasks, which include examining plans for constructing, changing, extending, or repairing each OSSF; granting permits; and checking the system’s installation, among others.

The OSSF’s authorized agents and representatives also investigate and respond to complaints to verify that the OSSF is in compliance with minimal requirements.

After that, the agent can file a criminal complaint with the local judge of the peace, who will then investigate the matter.

Industrial or hazardous waste cannot be introduced into an OSSF; instead, this waste will be handled in the soil, destroying the OSSF by actually killing the microorganisms that break down the biosolids and causing it to fail.

Keep in mind that septic systems are intended to manage human waste rather than chemicals.


All OSSFs will require maintenance at some point in their lives. Conventional anaerobic systems require the septic tank to be pumped out on a regular basis in order to remove sediments and prevent the system from backing up. It is advised that you pump your septic tank once every three to five years in order to avoid short circuiting the treatment process and causing damage. To acquire a list of registered sludge transporters in your region, go to theSludge Transporter Queryonline. Aerobic systems are more complicated and require more upkeep than anaerobic ones do.

  • A number of regulatory authorities have enacted more strict rules, which may include homeowner training or even prohibiting homeowners from performing upkeep on their properties.
  • In order to guarantee that the system runs appropriately, it is recommended that you contract with a licensed maintenance provider to verify, debug, and test the system as required by 30 TAC 285.91(4).
  • Once every six months if the system employs an electronic monitor, automated radio, or telephone to alert the maintenance provider of system or component failure as well as to monitor the quantity of disinfection remaining in the system, reporting might be lowered to once every six months.
  • If any needed repairs are not completed, the permitting authority will be notified of the failure.
  • The pills are extremely reactive, and within 10 minutes, they will have killed 99 percent of the germs present in the effluent.

On-Site Sewage Facilities – Frequently Asked Questions

A homeowner may build traditional septic systems under specific conditions, according to the guidelines for On-Site Sewage Facilities (OSSFs). A typical septic system is a suitable method of sewage treatment, but only if it is suited for the soil characteristics at the site in question. Water absorption is inadequate in locations with a high concentration of clay material in the soil, making it impossible for that sort of system to function correctly. This can result in runoff from the system, which can damage groundwater (wells and aquifers) or surface water (lakes and rivers) (creeks, rivers, andlakes).

The soil type influences whether or not a conventional system may be employed, and whether or not an aerobic OSSF is necessary.

Unfortunately, the great majority of the soil in this location has an excessive amount of clay, making it impossible for a typical system to work correctly.

What are the rules related to On-Site Sewage Facilities?

Our organization, the Angelina Neches River Authority, is the Authorized Agent for the purpose of administering and enforcing the State of Texas’ laws pertaining to OSSFs; however, we did not develop those rules. Please keep in mind that the great majority of the rules that regulate OSSFs are governed by the laws of the State of Texas, not the federal government. The following are the state rules that apply:

  • Chapter 366 of the Texas Health and Safety Code
  • Title 30,Texas Administrative Code Chapter 285
  • Title 30,Texas Administrative Code Chapter 30, Subchapters A and G
  • Title 30,Texas Administrative

Those regulations may be found in a document published by the Texas Commission on Environmental Quality (TCEQ) titled On-Site Sewage Facility Rules Compilation (RG-472) In addition to the state regulations, the AngelinaNeches River Authority’s Order Adopting Rules of the AngelinaNeches River Authority for On-Site Sewage Facilities has a few extra regulations. Certain revisions to that Order are tougher than the state’s standards, and we have them in that Order. Section 10 of the Order contains the extra requirements that must be followed.

What are the proper steps to obtaining a permit to construct a wastewater system in ANRA’s OSSF jurisdiction?

The first step is to fill out an ANRA septic application and pay the appropriate permits cost before moving forward. Forms and instructions are available on our Forms and Instructions Page, or they can be received by mail, in person, or by downloading them. It is necessary to have a wastewater system design performed by a Texas Registered Sanitarian as the second stage.

The design must be submitted to the American National Standards Institute (ANRA) for assessment in order to get the required wastewater system permit. Following the submission of the required papers, a permit to construct is often provided within 48 hours.

What number should I call if I have a question about my septic system or the ANRA permitting process?

ANRA OSSF Coordinator at 936-632-7795 will be able to assist you with any inquiries you may have about on-site wastewater septic system permitting, inspections, license transfers, or nuisance complaints.

Will my new wastewater system be inspected by an ANRA staff member?

Yes. The ANRA will inspect all new wastewater systems before they are put into service. The inspection must be conducted with the presence of the septic system installer.

Is a homeowner required to transfer ownership of a wastewater license when property is sold?

Yes. The ANRA will inspect all new wastewater treatment systems. Attendance at the inspection is mandatory for the septic system installer.

Can a licensed wastewater system be modified?

No. Modifications to any wastewater system are prohibited under Texas State Law. It will be necessary to obtain a new permission.

Is there a minimum lot size to install a wastewater system in the ANRA’s OSSF jurisdiction?

Yes, according to Texas State Law, a 12-acre site with a public water supply connection is required as a bare minimum. In the event that all setbacks on the septic system design have been satisfied, the ANRA may provide a deviation to this rule. The requirements may differ from one county to the next.

Is there a minimum distance required from a water well to a wastewater system?

Yes. If the water well has a concrete lined casing, a fifty-foot separation distance is necessary; otherwise, a hundred-foot separation distance is required.

Does ANRA investigate wastewater nuisance complaints?

Yes, provided a formal complaint form is filed with precise instructions, wastewater nuisance concerns will be examined in a timely manner. Downloadable versions of the nuisance complaint form are available on ourForms and Instructions Page.

What is a Licensed Installer?

Someone who has been granted a permit by the Texas Commission on Environmental Quality (TCEQ) to construct on-site sewage treatment plants (OSSF). There are two types of licenses available. Traditional OSSF systems can be installed by Installer Class I (OSI), who is allowed to do so (septic tanks, absorptive drainfields, unlined ET drainfields, leaching chambers, gravel-less pipe, and pumped effluent drainfields). Operator Class II (OSI II) is permitted to install ALL kinds of OSSF systems, save for those that are specifically excluded (including aerobic systems).

What is a Site Designer?

Someone who has been granted a permit by the Texas Commission on Environmental Quality (TCEQ) to construct on-site sewage systems (OSSF). Licensing options are divided into two categories. Occupational Specialty Installer Class I (OSI) is permitted to install typical OSSF systems (septic tanks, absorptive drainfields, unlined ET drainfields, leaching chambers, gravel-less pipe, and pumped effluent drainfields). All OSSF systems are approved to be installed using Installer Class II (OSII) (including aerobic systems).

Waco would require bigger lots for septic tanks under Plan Commission recommendation

According to a suggestion by the Plan Commission, larger lots for septic tanks would be required in Waco. It is the purpose of restricting the usage of local septic tanks to reduce the possibility of runoff reaching Lake Waco, which serves as the city’s drinking water source, according to Assistant City Manager Paul Cain. With a need to safeguard drinking water sources as a justification, the Waco Plan Commission is recommending that city council increase the minimum lot size required for a septic tank installation.

  • The largest developments in recent decades were subdivisions of around 20 lots, and even developments of that scale were few and far between, according to Peters.
  • Typically, just one or two lots were requested at a time from the sellers.
  • “We’re starting to see larger subdivisions come in with 40, 50, and 60-acre lots.” According to Assistant City Manager Paul Cain, the city’s first priority is reducing the danger of runoff reaching Lake Waco, which serves as the city’s drinking water source.
  • It was the need to safeguard groundwater and surface water through the expansion of municipal sewer service that prompted the city to annexe area along Highway 84 on the western border of town in 1998, according to him.
  • According to Peters, the likelihood of septic tanks contaminating groundwater increases as the number of tanks increases.

“It’s nearly hard to maintain a 50-lot subdivision of half-acre lots on a consistent basis throughout the course of a lifetime.” In accordance with state law, the Texas Commission on Environmental Quality requires that lots be at least half an acre in size, and the Heart of Texas Builders Association will likely request that the city adhere to that standard, though the association has not formally reviewed the proposal or taken a position, according to Executive Officer Kay Vinzant.

According to Vinzant, “If the state regulations require a half-acre property, we don’t believe the city should be any more severe.” If the modification is accepted by the city council, it could take effect as early as Sept.

A minimum of one acre would be required for any future subdivisions where new lots are being created, according to Peters.

For example, the city of Fort Worth adheres to this guideline.

Many different septic systems in Waco currently require at least an acre of land to be installed on them. It was a planning department team, led by Peters, that made the recommendation for the modification approximately a year ago. The team was entrusted with revising the city’s subdivision policy.

Public meeting issues

WCCCC TV televised and livestreamed the business session of the Plan Commission’s meeting on Tuesday, however the work session was not broadcast or webcast. During the Plan Commission work session, City Secretary Esmeralda Hudson stated that city staff members would be moving to the cityYoutube channel to stream some sessions, but that they were unable to get the technology to operate as anticipated. If you would like to hear an audio recording of the work session, you can request one from the City Secretary’s Office.

What Size Septic Tank Do I Need

The size of an underground septic tank is referred to as its total volume handling capacity in this article, and it will be discussed in further detail later in this article. For additional information on above-ground septic tanks and systems, see our page on above-ground septic tanks. The minimum septic tank capacity requirements are determined by a variety of variables. State, county, and/or city regulations may specify permitted tank sizes, as well as tank materials and installation.

The size of the septic tank will vary depending on whether it is intended for domestic or commercial usage; in this section, we will cover residential use.

Shortly stated, the required size of a septic tank will be determined by the following factors: (1) the specific septic system type; (2) local government requirements; (3) the compatibility of the ground geology; and (4) the anticipated volume of wastewater depending on the size of the residence.

However, this is not true.

Furthermore, plastic septic tanks will not corrode, are weatherproof, are waterproof, are less expensive, are lighter, and are easier to build.

1) The Specific Septic System Type

There are seven different types of septic tank systems, and the size of the tank required will vary depending on the system you choose. The scope of this article does not allow for a comprehensive discussion of each system type and its associated size requirements. We are referring to traditional gravity-fed anaerobic septic systems in this context when we say “system type.” The anaerobic septic system is the most prevalent type of septic system, and it is the one that most people think of when they imagine a septic tank.

The following are the seven most popular types of septic systems, and modern polyethylene septic tanks may be used in nearly all of these systems that require a tank, if not all of them:

  1. The following systems are available: conventional, gravity-fed, anaerobic systems
  2. Above-ground septic systems
  3. Pressure systems
  4. Anaerobic systems
  5. Mound systems
  6. Recirculating sand or gravel filters systems
  7. Bottomless sand filters systems

The following systems are available: conventional, gravity-fed, anaerobic systems; above-ground septic systems; pressure systems; anaerobic systems; mound systems; recirculating sand or gravel filters systems; bottomless sand filters systems.

2) Local Government Regulations

The laws for septic tanks imposed by local governments vary greatly across the United States. In part, this is due to the significantly diverse soil geography and water features that exist from state to state and can even differ by a few miles in some cases. In order to determine the appropriate septic tank size and the best position on the land for installation, it is essential to consult with local government rules first. Take, for example, theWastewater Treatment Standards – Residential Onsite Systemsdocument from the New York State Department of Health, which provides a comprehensive informational overview of codes, rules, and regulations frequently promulgated by governing bodies, as well as common terminology and definitions in the industry.

3) Suitability of the Ground Geology

The laws for septic tanks imposed by local governments differ significantly across the country. Due to the significantly diverse soil geography and water features found in each state, and sometimes even within a few miles of one another, this is the case In order to determine the appropriate septic tank size and the best placement on the land for installation, it is critical to consult with local government officials first. Review theWastewater Treatment Standards – Residential Onsite Systemsdocument from the New York State Department of Health for an example, as well as an informative discussion of codes, rules, and regulations frequently put forward by regulatory departments, as well as common terminology and meanings.

4) The Expected Volume of Wastewater

The restrictions for septic tanks imposed by local governments differ significantly across the United States. This is because to the widely diverse soil geography and water features that vary from state to state and can even vary by a few miles in certain cases. In order to determine the appropriate septic tank size and location on a property, it is essential to consult with local government rules. Review theWastewater Treatment Standards – Residential Onsite Systemsdocument from the New York State Department of Health for an example and an informative summary of codes, rules, and regulations frequently put forward by regulatory departments, as well as common terminology and meanings.

Minimum Septic Tank Capacity Table

For further information on the minimum septic tank capacity dependent on the number of residential bedrooms, please see the following table:

Number of Bedrooms Minimum Septic Tank Size Minimum Liquid Surface Area Drainfield Size
2 or less 1000 – 1500 Gallons 27 Sq. Ft. 800 – 2500 Sq. Ft.
3 1000 – 2000 Gallons 27 Sq. Ft. 1000 – 2880 Sq. Ft.
4 1250 – 2500 Gallons 34 Sq. Ft. 1200 – 3200 Sq. Ft.
5 1500 – 3000 Gallons 40 Sq. Ft. 1600 – 3400 Sq. Ft.
6 1750 – 3500 Gallons 47 Sq. Ft. 2000 – 3800 Sq. Ft.

Take note of the following in relation to the table above:

  • As defined by the State of New York, the Minimum Liquid Surface Area is the surface area given for the liquid by the tank’s width and length measurements. The range of Drainfield Sizes is depending on the kind of groundwater present. The State of Michigan provides the above-mentioned drainfield recommendations, which might vary greatly depending on local standards and terrain.

Additional Thought: Can a Septic Tank Be Too Big?

In the absence of consideration for cost, it is reasonable to ask: “Can a septic tank be too large?” The answer is a resounding nay. As long as the septic tank is placed appropriately, it is impossible for a septic tank to be too large; the only thing that can happen is that it is too little.

According to the majority of suggestions, constructing a larger-capacity septic tank is frequently the safer and more preferable solution. The following are the reasons behind this:

  1. With a bigger septic tank, you can adapt for changes in household consumption, such as those caused by parties or long-term guests. In the event that your family grows in size or you want to make improvements to your house, such as adding more bedrooms and bathrooms or installing new plumbing fixtures, having a bigger septic tank can save you the expense of installing a new tank.

Takeaways | What Size Septic Tank Do I Need

The septic tank size recommendations offered here are merely that: suggestions. They are built on a foundation of information gathered from government and academic sources. The actual size of the septic tank you require will vary depending on the factors discussed in this article. There is no “one-size-fits-all” solution when it comes to determining the appropriate septic tank size for your property. There is a great deal of variation depending on where you reside. With addition to providing a basic insight into the septic tank and system size that may be most suited to your application, the providedMinimum Septic Tank Capacity Tablecan also assist in cost estimations.

Before beginning any septic tank installation project, check and double-check with the state, city, or local county’s agency that is in charge of septic tanks, soil testing, and permissions.

If you’re searching for a chart of tank sizes, have a look at our page on the many sizes and quantities of septic tanks available.

Frequently Asked Questions

It is critical for persons who have OSSFs or who want to purchase property that has or will have an OSSF to understand the type of system, how it operates, and how to use and maintain it properly in order to avoid costly mistakes. Our inspectors have supplied answers to the commonly asked questions that have been compiled here for your convenience. Who is responsible for inspecting and approving my OSSF? The Texas Commission on Environmental Quality (TCEQ) has jurisdiction over the whole state, and it delegated authority to municipal governments in order to achieve its goals.

  • What is the role of an OSSF?
  • Sewage is composed of both liquids and solids, with liquids constituting the vast bulk.
  • The effectiveness with which particles are removed, the amount of liquid remaining, and the ability of the soil to dispose of the liquid are the most important variables for deciding the sort of system to be employed.
  • No.
  • If it does not seep into the earth, it will most likely evaporate into the atmosphere.
  • Does the fact that I am able to flush my toilet indicate that the system is operational?
  • Do you know what happens when the sewage leaves your home?
  • Numerous people have had systems that appeared to be functional only to discover that the pipe terminated in a stream and their sewage was creating an unhealthy environment for themselves and their neighbors.

That is two of the three characteristics that must be present in order for a typical septic system to be considered to be “functioning correctly.” Groundwater might be polluted even if there is no groundwater near the bottom of the system, or even if there is a method for sewage to reach the groundwater (for example, through fractures or fissures in the rock under the system).

  • There has been a lot of study done over the years that has helped us to better understand what happens to sewage once it gets into the ground.
  • Unfortunately, because many older systems were installed without proper information, it is difficult to determine if they are safe.
  • Essentially, you commission a site evaluation and submit the result together with an application and any expenses.
  • When the plan is submitted, we will review it (ideally) before it is built and inspected.
  • For further information, please refer to the OSSF Permit Packet located on the main page.
  • A state-licensed installer or a homeowner, if the building is a single-family property, are both acceptable options.
  • OSSF Rules & Regulations are available on our main OSSF page, which you may access by clicking here.

An aerobic system differs from a septic tank in several ways.

Septic indicates that there is no dissolved oxygen present and that the bacteria are producing their own oxygen.

An aerobic tank is one in which air is pushed into the water, allowing a whole other set of bacteria to flourish.

Although the effluent from an aerobic system is far cleaner than that from a conventional system, it is still not safe.

Is it permissible to dispose of aerobically treated effluent on the ground?

The surface of your property can be used to dispose of a unit that has been approved (they have been properly inspected) and has been disinfected (most likely with a chlorinator).

What should I do to keep my septic tank in good working order?

2) Do not use the toilet as a trash can, and use a garbage disposal only when absolutely necessary – if you can’t digest it, neither can your septic tank.

What about septic tank additives, do you think they’re necessary?

It is common practice for people to inject yeast, cow dung, or different substances purchased at a shop into their systems, although they do nothing to help them.

It is unlikely that you will be able to modify the bacteria concentration in the tank(s) without causing significant damage.

What about additives for an aerobic tank?

Under no circumstances should you include anything other than ordinary household rubbish and goods that have been approved by the manufacturer.

How much land will I need to dedicate to my sewage treatment facility?

According on our past experience, any plot of land less than an acre can be challenging (this is a guideline, not a necessity).

When a piece of property is divided, the standards for its size remain in effect.

Each piece of real estate, no matter how large or tiny, will be appraised on its own merits and value.

Make sure to read the next question carefully before answering.

For On-Site Sewage Facilities, the state legislation specifies two options: one acre if you want to drill a well, or one half acre if you plan to use only public water.

You must, however, have enough land to match the needs of the system you intend to install.

Extra Territorial Jurisdiction is the authority that oversees the implementation of certain city ordinances.

Keep in mind that each piece of historic, existing, and documented property is dealt on an individual basis.

If you are within the boundaries of a city, that city will have control over you.

What size of septic tank do I need?

Probably one of the last things on your mind when you are constructing a new house is the location of your septic system. After all, shopping for tanks isn’t nearly as entertaining as shopping for cabinetry, appliances, and floor coverings. Although you would never brag about it, your guests will be aware if you do not have the proper septic tank placed in your home or business.

septic tanks for new home construction

The exact size of the septic tank is determined mostly by the square footage of the house and the number of people who will be living in it. The majority of home septic tanks have capacities ranging from 750 to 1,250 gallons. A 1000 gallon tank will most likely be required for a typical 3-bedroom home that is smaller than 2500 square feet in size. Of course, all of this is dependent on the number of people who live in the house as well as the amount of water and waste that will be disposed of through the plumbing system.

For the most accurate assessment of your septic tank needs, you should speak with an experienced and trustworthy sewer business representative.

planning your drainfield

Here are some helpful hints for deciding where to locate your drainfield when you’re designing it.

  • Vehicles should not be allowed on or around the drainfield. Planting trees or anything else with deep roots along the bed of the drain field is not recommended. The roots jam the pipes on a regular basis. Downspouts and sump pumps should not be discharged into the septic system. Do not tamper with or change natural drainage features without first researching and evaluating the consequences of your actions on the drainage field. Do not construct extensions on top of the drain field or cover it with concrete, asphalt, or other materials. Create easy access to your septic tank cover by placing it near the entrance. Easy maintenance and inspection are made possible as a result. To aid with evaporation and erosion prevention, plant grass in the area.

a home addition may mean a new septic tank

Do not make any big additions or renovations to your house or company until you have had the size of your septic system assessed. If you want to build a house addition that is more than 10% of your total floor space, increases the number of rooms, or necessitates the installation of new plumbing, you will almost certainly need to expand your septic tank.

  • For a home addition that will result in increased use of your septic system, your local health department will require a letter from you that has been signed and authorized by a representative of your local health department confirming that your new septic system is capable of accommodating the increase in wastewater. It is not recommended that you replace your septic system without the assistance of a certified and competent contractor.

Bastrop County has implemented the Texas Commission on Environmental Quality (TCEQ) guidelines found in Title 30 Texas Administrative Code Chapter 285. As part of the Bastrop County On-Site Sewage Facilities Order, the county has enacted more rigorous standards, which include the following:

  • All septic system installations and upgrades require a permit, regardless of the amount of land involved
  • It is necessary to get an OSSF permit for any construction that will be utilized as a dwelling in order to ensure compliance with the regulation. After the first two-year obligatory maintenance contract with a Licensed Maintenance Provider who has received authorized training, homeowners may do their own maintenance on their aerobic systems. With the exception of RV parks, the minimum size factor for any construction up to 1,500 square feet is 180 gallons per day. This includes guest homes, workshops, detached garages, recreational vehicles (RVs), and other structures up to 1,500 square feet. RV parks are defined as groups of five or more recreational vehicles on a single parcel of land, with a water capacity of 50 gallons per day. In addition, the Bastrop County Infrastructure Requirements for Lodging and Recreational Vehicle Park Developments describe an RV park in a somewhat different way.
  • All proposed and existing structures, including additional dwellings, guest houses, septic systems, outbuildings, barns, sheds, and other similar structures, must be included in the septic design. A diagram must also be included to depict water lines, water meters, water wells, overhead electric lines, roads, and access easements Surface irrigation systems must not be built with spray patterns that overlap one other. It is necessary to have a minimum of 750 gallon septic tank for each residence prior to the installation of the requisite treatment and disposal components if the system is being planned for more than one occupied structure.

A permit is necessary for the construction, installation, alteration, extension, or repair of an On-site Sewage Facility, with a few exceptions (OSSF). Check with the Bastrop County Environmental and Sanitation Services Department before proceeding since local permitting processes might be more severe than state law in some cases. Emergency repairs (such as the replacement of tank lids, inlet and outlet devices, and the repair of solid lines) do not require a permit; nevertheless, they must be notified to this office within 72 hours of the start of the repairs being carried out.

Despite the fact that Bastrop County maintains a list of OSSF professionals, the county does not support or guarantee the licensing, certification, or performance of any individual included on the list.

We propose that you get bids from a number of different persons, verify their licensing status, and request references.

  • Sludge is formed when solid waste falls to the bottom of the tank, where microorganisms in the tank break down the solid materials, resulting in the formation of sludge. Water: This is referred to as greywater, and it is not appropriate for drinking but is not considered harmful. Scum is made up of fats and oils that float to the surface of the tank.

The placement of the outlet and inlet pipes, as well as baffles, prevent sludge and scum from exiting the tank. Wastewater, also known as effluent, is channeled through pipes to a drain field.

What happens if a septic tank is not pumped?

In the event that you do not routinely pump your septic tank (every 3-5 years, however this range may shorten or prolong depending on a few conditions), the following problems may occur.

  • The sludge accumulates
  • The deposit begins to flow into the drain field, polluting the field and possibly contaminating the surrounding groundwater. Pipes get blocked and eventually burst. Pumps become clogged and eventually fail. You’ll wind up damaging your drain field and will have to replace it as a result.

What’s the difference between a septic tank and a cesspool?

It is the way in which they work to disseminate waste that distinguishes a cesspool from a septic tank, and The expenses of pumping them are the same as before.

  • Uncomplicated in design, a cesspool is just a walled hole with perforated sides into which wastewater runs and slowly dissipates into the earth around it. Once the surrounding earth has become saturated, you’ll need to dig a new cesspool to replace the old one. Cesspools are not permitted in many parts of the United States, and you will be required to construct a septic system instead. An effective septic system functions in the same way as a cesspool, but it has two unique components: the septic tank and the drain field.
  • The septic tank enables wastewater to enter while only allowing grey water to exit through precisely placed input and outlet hoses to the drain field. Scum and solid waste (sludge) stay trapped within the vessel. When compared to a cesspool, the drain field distributes grey water over a broader area, enabling it to flow into the soil and cleanse.

How do I keep my septic system healthy?

Maintain the health of your system by keeping certain specified contaminants and chemicals out of your septic system, such as the following:

  • A variety of anti-bacterial hand washing soaps, certain toilet bowl cleansers, bath and body oils, as well as a variety of dishwashing detergents are available for purchase. In regions where separate systems are now permitted, laundry detergents and bleach are permitted. a few types of water softeners

Important to note is that while biological additions are unlikely to be dangerous, many chemical additives that are touted as a way to save you money by not having to pump your septic tank may actually cause damage to your septic system.
