What Size Septic Tank Do I Need Tceq?

The tank must serve a single-family residence on a property that’s 10 acres or larger (this residence can be the only residence located on the land). The tank cannot cause a nuisance or pollute groundwater.

  • The size of the septic tank you will need depends mostly on the size of the house and the number of people who will reside there. Common residential septic tanks range in size from 750 gallons to 1,250 gallons. Septic Tank Basics

How do I know what size septic tank I need?

Consider the Size of Your Property The larger your home, the larger the septic tank you’re going to need. For instance, a house smaller than 1,500 square feet usually requires a 750 to 1,000-gallon tank.

How big of a septic tank is needed 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.

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.

How long will a 300 gallon septic tank last?

Therefore, it will take about 5 years for one adult to fill 300 gallons of a 1,000-gallon septic tank with sludge and scum. A family of four will fill the 300-gallon storage volume of a 1,000-gallon septic tank in about 1.5 years.

How often does a 1000 gallon septic tank need to be pumped?

For example, a 1,000 gallon septic tank, which is used by two people, should be pumped every 5.9 years. If there are eight people using a 1,000-gallon septic tank, it should be pumped every year.

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 often should a septic tank be pumped?

Inspect and Pump Frequently The average household septic system should be inspected at least every three years by a septic service professional. Household septic tanks are typically pumped every three to five years.

How much does it cost to pump a septic tank?

How much does it cost to pump out a septic tank? The average cost is $300, but can run up to $500, depending on your location. The tank should be pumped out every three to five years.

How big should my drain field be?

A typical septic drainfield trench is 18 to 30 inches in depth, with a maximum soil cover over the disposal field of 36″; or per the USDA, 2 feet to 5 feet in depth.

Can a leach field be too deep?

Drain Field Depth The result is a drain field about 3 to 4 feet deep. Sometimes, however, a drain field may need to be a bit shallower and can result in drain pipes as close to the surface as 6 inches. Underground obstacles can cause this situation.

Does shower water go into septic tank?

From your house to the tank: Most, but not all, septic systems operate via gravity to the septic tank. Each time a toilet is flushed, water is turned on or you take a shower, the water and waste flows via gravity through the plumbing system in your house and ends up in the septic tank.

Can you pump a septic tank too often?

If your septic tank is pumped too often, that bacteria will have no place to go but out into the drain field, which can lead to clogs and failures. So unless your septic tank’s sludge and scum levels reach certain thresholds, it’s actually beneficial to leave the septic tank alone.

What are the signs that your septic tank is full?

Here are some of the most common warning signs that you have a full septic tank:

  • Your Drains Are Taking Forever.
  • Standing Water Over Your Septic Tank.
  • Bad Smells Coming From Your Yard.
  • You Hear Gurgling Water.
  • You Have A Sewage Backup.
  • How often should you empty your septic tank?

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.

  1. 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.
  2. 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).
  3. 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.
  4. If any needed repairs are not completed, the permitting authority will be notified of the failure.
  5. The pills are extremely reactive, and within 10 minutes, they will have killed 99 percent of the germs present in the effluent.

Getting a Permit for an On-Site Sewage Facility – Such as a Septic System

A permit is necessary for the construction, installation, alteration, extension, or repair of an On-site Sewage Facility, with a few exceptions as mentioned below (OSSF). Always double-check with your local permitting authority before proceeding. Local permitting programs may be more strict than those mandated by state law in some cases. Texas law provides allow for an OSSF to be excluded from permitting requirements if the OSSF meets the following criteria:

  • If the OSSF serves a single family residence on a tract of land that is 10 acres or larger, it is not a nuisance or a groundwater contaminant
  • All parts of the OSSF are at least 100 feet from the property line
  • The effluent is disposed of on the property
  • And, the single family residence is the only dwelling on the tract of land

It is not necessary to get a permit for emergency repairs (such as the replacement of tank lids, input and outlet devices, and the repair of solid lines), but they must be notified to the appropriate permitting body within 72 hours of the start of the repairs. Emergency repairs are specified in 30 TAC Subchapter D, Section 285.35 of the Texas Administrative Code. Even if a permit is not necessary, the OSSF must adhere to the state’s minimal requirements.

Texas Septic Tank Requirements

It is not necessary to get a permit for emergency repairs (such as the replacement of tank lids, inlet and outlet devices, and the repair of solid lines), but they must be notified to the appropriate permitting authorities within 72 hours of beginning the repairs. 30 TAC Subchapter D, Section 285.35, defines emergency repairs. It is necessary for the OSSF to fulfill basic state requirements even if a permit is not required.

In Texas, they say that everything is larger, and this is certainly true in terms of septic tank standards. To have an aseptic tank constructed in the Lone Star State, you’ll have to go through a number of hoops, including site inspections, permits, and permitted installation processes, to name just a few of them. If you’re building a home on the range, here are some things to bear in mind while establishing a septic system: Making sure you have the right permits in place before constructing a new septic tank or updating an existing one is the first step to taking care of business.

The majority of septic tank installations in the state of Texas require a permission from the state. There are, however, certain exceptions to this rule. Texas state law does not require a permit if the tank complies with the following requirements:

  • In order to qualify, the tank must serve a single-family dwelling located on a property with a minimum of 10 acres in size (and this residence might be the sole residence on the site)
  • The tank must not be a source of public nuisance or harm groundwater. Neither the tank nor the property can be more than 100 feet apart from each other. The tank is unable to dispose of the wastewater on the land
  • As a result,

Emergency septic tank repairs are another exemption, and they are not required to get a permit in this case. Even if you complete the repairs within 72 hours after starting them, you must still submit them to the appropriate permitting authorities. In addition to the state criteria, licenses issued by local authorities may be subject to more strict regulations.

Grandfathered Septic Tank Systems

If the following conditions are satisfied, a house septic tank in Texas may be grandfathered and exempt from some regulatory procedures, depending on the circumstances:

  • The system must have been installed before to September 1, 1989, or prior to the establishment of an authorized installation program by a local dealer The tank must be equipped with a treatment and disposal system. The tank is not being utilized to treat a bigger volume of sewage than it was when it was initially constructed.

Septic Tank Site Evaluation

Installed systems must have been completed before September 1, 1989, or before a local dealer established an approved installation program. Treatment and disposal facilities must be included in the tank design. The tank is not being utilized to treat a bigger volume of sewage than it was when it was initially erected; nonetheless,

DIY Septic Tank Installation

Under Texas law, it is permissible to construct your own septic system. Certain systems, on the other hand, cannot be marketed to individual property owners and must instead be sold through manufacturing representatives. Additional requirements include that if you pay for any work done by contractors while installing the tank yourself, the contractors must be licensed to do so by the State of Texas. One such instance would be the hire of a contractor to dig a hole for the installation of the septic tank.

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).

See also:  Where Can I Buy A Septic Tank In Eugene? (Solution)

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:

  • 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. Remember that the great majority of the rules that regulate OSFs are enacted by the State of Texas. If you have any questions about this, please contact us. The state rules that apply are as follows:

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.

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. When a property is sold, Texas state law mandates that the homeowner transfer ownership of the home’s wastewater treatment system. If the transfer is not completed, the license may be revoked under the terms of the legislation. It is possible to receive a license transfer application at the ANRA office or by visiting ourForms and Instructions Page.

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?

A person must first be recognized as a certified sanitarian by the Texas Department of State Health Services or as a professional engineer by the Texas Board of Professional Engineers in order to lawfully deliver a site design.

Heres a look at texas septic system regulations

The Texas Department of State Health Services or the Texas Board of Professional Engineers must recognize an individual as a registered sanitarian or as a professional engineer before that individual may lawfully deliver a site design.

Penalties for Non-Compliance

According to Texas septic system legislation, a homeowner who deviates from the approved plan may face legal consequences. He or she may also be subject to legal consequences if they use an insufficient septic system. Site evaluators, installers, and apprentices may have their licenses revoked if they are found guilty of any of the following violations: Information or paperwork that has been falsified. Not exercising sound, professional judgment when carrying out their responsibilities Contravening the provisions of applicable rules or state legislation.

It is possible to find out who is responsible for providing permits, completing inspections, and granting final approval of on-site sewage systems in your region by consulting your local health department or the Texas Commission on Environmental Quality office in your area.

Septic Systems

Septic tanks are available in a number of different designs and sizes. The size of the tank is determined by the number of bedrooms and square footage in the home. If you do not have proper installation records, we can give you a decent approximation of the size over the phone or measure your tank. Most of the time, your septic tank is buried near your house. A sewage pipe connects it to the rest of your home’s plumbing system. The pipe, which is normally 3 to 4 inches in diameter, can be located in your foundation or crawl space and should not be disturbed.

The information you’ve acquired allows you to estimate the position of the tank and probe carefully with a shovel or iron digging rod to identify the four corners of the tank lid as well as its estimated depth using an iron digging rod.

It collects and treats waste.

Grease and lighter materials float to the surface of the water, whereas heavier solids sink to the bottom.

If sludge is detected in your water, the system is in a shutdown or failure status. The Texas Commission on Environmental Quality (TCEQ) licenses and regulates septic systems (also known as On-Site Sewage Facilities or OSSFs) throughout the state (TCEQ).

Frequently Asked Questions about Septic Systems

Septic tanks are available in a wide range of designs and sizes for purchase on the market today. Size of tank is determined by the number of bedrooms and square footage of the home. Alternatively, if you do not have exact records from the installation, we can provide you with a decent approximation of the size over the phone or measure your tank. Typically, your septic tank is buried close to your home or building. A sewage pipe connects it to the rest of your home’s plumbing. In most cases, the pipe is 3 to 4 inches in diameter and can be located in the foundation or crawl space of the home.

The information you’ve acquired allows you to estimate the position of the tank and probe carefully with a shovel or iron digging rod to discover the four corners of the tank lid as well as its estimated depth using a shovel or iron digging rod As its name suggests, an underground septic tank holds waste that must be treated before it can be disposed of.

The bottom of the container holds heavier particles, while the top of the container holds grease and other lighter solids.

A system shutdown or failure occurs if there is sludge present in the water supply.

  • System types that are conventional include passive systems with drainfields, gravelled or stone systems, chambered system leachfields, low-pressure dosing systems, evapotranspiration systems, and aerobic wastewater treatment systems.

Questions Applicable to All Types of Septic Systems

Is it necessary for me to seek a permit in order to repair my septic system? Yes. Repairing any form of septic system in Texas requires a permit that has been granted by the state, with limited exceptions. In order to ensure that the individual performing the repairs has sufficient expertise and knows the proper methods and protocols for fixing the system, this law was enacted. Environmental protection, as well as the protection of the homeowner and his neighbors, are the goals of the law. What is the procedure for getting a permit for a repair or an installation?

  • The kind of soil, the location of the system in relation to creeks, rivers, lakes, and property lines, as well as the type of septic system to be repaired or rebuilt, as well as the installation or repair plan, are all taken into consideration in the permit application.
  • In light of the possible problems associated with acquiring permits, the majority of service providers ask that the homeowner complete and submit the application on their behalf.
  • Is it safe to flush toilet paper down the toilet?
  • Based on the number of bedrooms in the house, the size of the holding tank is determined.
  • Because of this, using toilet paper should not pose an issue as long as the system is not needed to process more wastewater than it was designed to manage.

In what intervals do I require pumping of my system? This answer is dependent on the size of the system as well as the amount of individuals that are utilizing the system to provide it. For the average household, the answer is every three to five years, depending on the circumstances.

The Texas Commission on Environmental Quality contributed the information in the table above. Is it necessary for me to add any supplements to my system? The majority of the time, additives are not required to keep a well functioning septic system running. However, there are occasions when a system becomes overwhelmed with organic material, and the enzymes and bacteria found in additives might actually be beneficial. The possibility of this occurring arises when a system is temporarily forced to process more garbage than it was designed to handle, as in the case of repeated big parties or an influx of guests for a prolonged period of time.

Flooding Related Questions Applicable to All Types of Septic Systems

Water overflowing from a traditional drain field might cause a septic system to flood if the field has been saturated by rain or rising stream, creek, or river water. Flooding happens in an aerobic system when the aerobic tanks become overflowing with runoff rain water and the system ceases to operate. In any instance, the first indicator that there is a problem is generally the fact that the toilets are no longer flushing correctly. In addition, because shower and bath drains are typically positioned at the lowest gravity point in the home, raw sewage may back up into these drains first.

  1. If at all possible, avoid using the system when the drain field or tanks are completely submerged in water. It is unlikely that the wastewater will be cleansed, and it will instead become a source of pollution. Conserve water to the greatest extent feasible while the system strives to recover itself and the water table drops. Make every effort to keep silt from entering the pump chamber if you have an aerobic septic system (with electric pumps). The presence of silt in the pump chamber after flooding causes it to settle, which might block the drainfield or harm the pump if it is not removed before flooding occurs. When opening the septic tank for pumping when the earth is still damp, proceed with caution and extreme caution. Mud and silt may find their way into the tank and end up in the drain field. In addition, pumping out a tank that is resting in moist soil may cause the tank to “jump out” of the earth as it is being removed. Because the earth may not have entirely settled and compacted, newer systems are more prone to pop out than older systems. While the land is still wet or flooded, it is not recommended to dig into the tank or drainfield area. Try to avoid operating any heavy gear near the drainfield or tanks while they are wet, since they are particularly prone to harm while they are flooded. This type of action has the potential to permanently impair the soil’s capacity to transmit fluids. When the septic tank is flooded, it frequently removes the floating crust of fats and oils that has formed on top of the tank. Some of this muck may float to the surface and plug the outflow tee partly. First and foremost, if your septic system is backing up into your home, check for blockages in the tank’s outflow. Clean up any floodwater that has accumulated in the house without dumping it into the sink or toilet, and give the water time to recede before continuing. Floodwaters in a house that are later pushed through or pumped through the septic tank will generate greater than typical flow rates through the system as a result of the flooding. As a result, the likelihood of an outlet tee being clogged increases considerably. Avoid coming into contact with any electric pump or equipment that may have been submerged during the flood unless the device has been thoroughly cleaned and dried. Mud and silt may have blocked aerobic systems, upflow filters, trickling filters, and other media filters, causing them to get clogged. Prior to restarting the system, these systems will need to be washed, scraped, and otherwise cleaned
  2. And

What should I do once the floodwaters have receded from my home?

  1. If you have an in-ground well, wait until the water has been tested by your county health agency before drinking it. Please refrain from making use of your sewer system until the water level in your soil absorption field is lower than any water level everywhere else in your home. If you feel that your septic tank has been damaged, you should get it professionally inspected and maintained. Damage can be detected by the presence of apparent settling or settlement of the ground above the tank, as well as the incapacity of the system to absorb extra water. Because most septic systems are below ground and entirely protected, flooding does not do significant harm to them. Septic tanks and pump chambers, on the other hand, can get clogged with silt and dirt, necessitating their cleaning. A new system may be required if the soil absorption field becomes clogged with silt due to the fact that there is no practical means to clear up the buried lines in an absorption field. In order to avoid the risk of harmful gases and germs being released into the environment, get your tanks fixed or cleaned by skilled professionals. Cleaning and disinfecting the basement floor should be done if sewage has backed up into the space. A chlorine solution containing half a cup of chlorine bleach per gallon of water should be used.

Questions Specific to Aerobic Wastewater Treatement Systems

What is the process for renewing my Aerobic System maintenance contract? Upon installation, each aerobic system is accompanied with a complimentary two-year maintenance contract, which begins the day after the installation procedure is complete. The installation business is first responsible for providing this service. Because most systems are reasonably simple to maintain during their first two years of operation, several installers do not provide maintenance services after that initial two-year period.

  • Every year after you sign a maintenance contract with Septic Solutions, your agreement will be automatically renewed.
  • The homeowner is responsible for all costs related with maintenance, chlorine, and pumping (as needed) of the pool.
  • Our customers may select the contract that is most appropriate for their needs.
  • The following activities are carried out during a normal maintenance visit: This will differ depending on the service provider.
  • Aside from that, we also examine the amount of sludge in your holding tank.
  • What role do the air and water pumps play in an aerobic system, and how significant are they?
  • The air pump is used to aerate the wastewater and speed up the breakdown processes in the wastewater treatment plant.

If one of these systems fails to function correctly, the wastewater will become septic.

Is the water that is released from an aerobic system safe to consume?

Before the water is sprayed via the spray field, it is treated to destroy or eradicate germs, and then it is discharged again.

How much does chlorine cost on an annual basis?

We give our clients the option of installing a Smart=Chlor Liquid Chlorinator, which may be run at a far lower cost of chlorine than a traditional liquid chlorinator.

The most common causes of aerobic system odors are: 1) an excessive amount of chemicals being introduced into the system, 2) the presence of a restriction in the air supply, 3) more wastewater being introduced into the system than the system was designed to handle, and 4) an insufficient supply of disinfectant.

When should I add chlorine to my water?

You should keep an eye on your system to ensure that there are always a minimum of 2-3 chlorine pills in the tube at any one moment.

According to Texas law, homeowners are permitted to maintain their own wastewater systems if they have completed a 6-hour, state-approved Basic Wastewater Operations Course, passed the state test, obtained a Class D Wastewater Certificate, and obtained a certification from the manufacturer of their specific wastewater system.

Given the time commitments required to obtain a certificate, the inherent unpleasantness of checking sludge levels, and the requirement that only licensed septic providers perform all necessary repairs, the majority of customers prefer to have their system’s maintenance performed under contract with a certified sewer contractor.
