How do you dissolve septic tank sludge?
How to Reduce Sludge in a Septic Tank Without Pumping
- Install an aeration system with diffused air in your septic tank.
- Break up any compacted sludge.
- Add a bio-activator or microbe blend.
- Maintain the aeration system.
- Add additional Microbes as required.
What happens to sludge in septic tank?
In reality, most of the faecal sludge collected from septic tanks is dumped into rivers, drains and sewers or emptied untreated into agricultural fields and low-lying areas. A tiny portion of it reaches STPs, though ideally it should not.
How long does it take waste to decompose in a septic tank?
In addition, during the approximate two to three days wastewater resides in the septic tank, the biodegradable organics in the septic tank are expected to decompose, in the absence of oxygen, into less complex organic compounds.
Can you put too much bacteria in a septic tank?
Too much of a good thing can cause problems. A septic system relies on the correct balance of bacteria to do its job. An overpopulation of bacteria can deplete the oxygen in the septic tank and turn the environment septic. A septic, septic system is one in which the ecosystem within the tank is out of balance.
What eats sludge in septic tank?
One example of a homemade remedy is to flush ¼-½ a cup of instant yeast down your toilet. The yeast eats away at the sludge and helps loosen it, breaking it down so that wastewater can get through.
Do septic tank additives really work?
There is little scientific data to suggest that you should add bacteria or enzymes to your septic system. The United States Environmental Protection Agency reported that biological additives do not appear to improve the performance of healthy septic tanks.
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?
How do I check the sludge level in my septic tank?
To measure the sludge layer:
- Slowly lower the tube into the septic tank until it touches the bottom of the tank.
- As the device is slowly pulled out of the water, the check valve closes capturing a liquid/solid profile of the septic tank water. The thickness of the sludge layer can be measured.
Where does poop go after septic tank?
After the waste is filtered, it moves into a sand container, where sand, ashes, and gravel settle at the bottom of the container. The gravity pull allows sewage to run through the pipes of each structure and sends the waste material to a sewer line that flows into larger vessels to the sewage treatment plant.
Does poop dissolve in septic tank?
Solid waste (a.k.a., poop) can build up, break down, fuse and create a mass that does some really bad things to your septic system. Here is what you can do, both prevention and repair-wise, with regards to solid waste becoming too solid in your septic tank.
How do I increase bacteria in my septic tank?
Flush a packet of brewer’s dry yeast down one toilet on the bottom floor of your house once a month. The yeast will help add “good” bacteria to your septic tank and break down waste.
How often should you pump your septic tank?
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.
Do I need to add enzymes to my septic tank?
But septic tanks don’t really need help from extra additives. As long as you are only putting wastewater and toilet paper down the pipes, the tank can take care of its job on its own. Putting anything extra in can cause more harm than good and it’s best to stick to the tanks natural ecosystem when possible.
How long does it take for Ridex to work?
The enzymes in RID-X® begin working as soon as they come in contact with water. The bacteria take 2-4 hours to germinate and then begin to break down solid waste. If the temperature and conditions are favorable, then the bacteria will multiply to the maximum level that the environment will allow in about 2-4 days.
What is the best bacteria to put in septic tank?
Much like your stomach, septic tanks need good bacteria and enzymes to break down the solids that pass through it. These beneficial bacteria and enzymes can come from several sources, but our favorite is actually rotten tomatoes. These naturally occurring enzymes are proteins called Pectinase or Pectinolytic enzymes.
Wastewater and the Septic System
What is a septic tank, and how does it work? All waste from toilets, showers, sinks, and washing machines is sent to a septic tank, which is connected to a septic system for the remaining 20% of American houses and institutions that do not have sewer connections. In the first treatment of wastewater by capturing particles and settleable organic matter before dumping of the wastewater (effluent) to the drainfield, a septic tank is a large-volume, waterproof tank. Construction and operation of the septic tank are relatively straightforward; nonetheless, via the intricate interplay of physical and biological processes, the tank serves a variety of vital purposes.
The following are the most important functions of a septic tank: Take care of all of the wastewater generated by the residence or institution.
Reduce the amount of solids that have collected and allow them to decompose.
This reasonably calm body of water allows the wastewater to be kept for a long enough period of time to allow the particles to separate through a combination of settling and flotation processes.
- Scum: Substances that are lighter in weight than water (oil, grease, and fats) float to the surface of the water and produce a scum layer.
- Aerobic bacteria are actively engaged in the digestion of floating particles.
- Because sludge is denser than water and fluid in nature, it settles to the bottom of the tank in a thin, flat layer.
- As the bacteria die, they decompose and become part of the sludge.
- It is the clear liquid that exists between the scum and the sludge layers.
- The floating scum layer on top of the tank and the sludge layer at the bottom of the tank each take up a specific proportion of the total volume of the tank’s total volume of water.
- As the wastewater rests in the tank, the active solids separation takes place, resulting in cleaner wastewater.
- In order for effective separation of solids to occur, the wastewater must be allowed to rest for an extended period of time in the tank’s quiescent conditions.
A relationship exists between effective volume and daily wastewater flow rate, and this relationship may be expressed as In this equation, retention time (days) equals effective volume (gallons) divided by flow rate (gallons per day) Sludge and scum storage require a minimum retention duration of at least 24 hours, during which half to two thirds of the tank capacity is consumed by sludge and scum storage, according to standard design rules for holding tanks.
- Please keep in mind that this is a bare minimum retention duration under the conditions of a large accumulation of solids in the tank.
- As sludge and scum collect and take up more space in the tank, the effective capacity of the tank steadily decreases, resulting in a shorter retention time.
- In addition to clogged pipes and gravel in the drainfield, which is one of the most prevalent reasons of septic system failure, pathogenic bacteria and dissolved organic pollutants can develop as a result of this practice.
- A common design rule is that one-half to two-thirds of the tank capacity should be set aside for sludge and scum collection, depending on the size of the tank.
- In practice, however, the pace of solids collection varies significantly from one situation to another, and the real storage duration can only be established by periodic septic tank inspections.
- While new solids are continuously being added to the scum and sludge layers, anaerobic bacteria (bacteria that do not require oxygen to survive) are consuming the organic material in the solids, allowing the process to continue.
- Anaerobic decomposition causes a gradual reduction in the amount of collected solids in the septic tank as a result of the process.
Compaction of the older, underlying sludge also contributes to the reduction in the volume of the sludge layer.
Using EnviroZyme’sConcentrated Grease Control 10XandSeptic Treatmentproducts can help prevent non-clarified wastewater from running through an outlet that does not have adequate effective volume and/or retention time.
This successfully minimizes the number of layers in a septic tank as well as the frequency with which it must be pumped out.
The results were interesting.
This was due to the fact that natural wastewater already contains bacteria, and these bacteria gradually regained dominance in the biomass.
(Click on image to expand) In addition, we measured the carbonaceous biochemical oxygen demand (cBOD) in the clear liquid component of each tank, which was approximately 10 inches below the surface of the liquid.
This implies that, once cleaned, the effluent from a septic tank will help to limit the quantity of dissolved organic pollutants that enters the surrounding environment.

The role of enzymes and bacteria in a septic tank
Wastewater from residences is disposed of into a septic tank for treatment in areas where municipal sewer lines are not readily available or are inaccessible. The presence of microorganisms, particularly bacteria, in the septic tank helps to break down and liquefy organic waste. The treatment of wastewater in most septic systems is divided into two primary steps. When wastewater is fed into the septic system, the solids fall to the bottom of the system, where they combine with the anaerobic bacteria to produce the sludge and scum layers.
After passing through the second phase, the effluent is discharged into the drainfield region, where it is further treated by physical and biological processes as it percolates through the soil.
What are enzymes?
Bacterial enzymes are a class of proteins that are released into the environment. Enzymes are quite selective in terms of the types of organic materials that they degrade. Enzymes, in contrast to bacteria, are not living organisms. They are incapable of growing or reproducing. Enzymes are often produced by bacteria and serve as catalysts for anaerobic digestion, which occurs in the absence of oxygen. Enzymes may be thought of as blades that cut through complicated molecules and break them down into smaller fragments that are more digestible for bacteria to consume.
Types of enzymes found in septic systems
Following are some of the most essential enzymes in sewage treatment systems. Protease is a digestive enzyme that breaks down protein-based waste such as blood and feces. Lipase is a digestive enzyme that breaks down fats, greases, and oils. Amylase is a digestive enzyme that breaks down carbohydrates such as porridge, rice, pasta, and so on. Cellulase is a digestive enzyme that breaks down cellulose, such as that found in paper-based goods. Urease is a digestive enzyme that breaks down urea.
The majority of these enzymes are generated by bacteria in their natural environment.
Organic matter and enzymes such as amylase, protease, cellulases, and lipases are introduced into the septic tank by Bio-maintenance Sol’s products in order to break down the organic waste and aid in the digestion process in the tank.
What are bacteria?
The enzymes listed below are some of the most significant in septic systems. In the body, protease is responsible for breaking down protein-based waste, such as blood and feces. Lipase– is a digestive enzyme that breaks down fats, greases, and oils in the stomach. A substance known as amylase is responsible for the breakdown of starches such as those found in porridge, rice, pasta, and other grains. Cellulase is a digestive enzyme that breaks down cellulose, which is found in paper-based goods, among other sources.
Any plant material, such as vegetables, can be broken down by xylanase.
If you want to enhance the number of bacteria in your system, it’s a good idea to add biological supplements.
Organic matter and enzymes such as amylase, protease, cellulases, and lipases are introduced into the septic tank by Bio-maintenance Sol’s products in order to break down the organic waste and assist in the digestion process in the tank.
Types of bacteria found in the septic tank
When it comes to septic systems, there are four basic kinds of bacteria to consider. There are anaerobic, aerobic, facultative, and bacterium spores among these types of bacteria. Let’s take a closer look at each of these in turn.
As the name implies, anaerobic bacteria flourish in conditions with little or no oxygen, which is why they can be found in typical septic systems. They generate energy by using chemicals like as nitrates and sulfates, which helps to slow their metabolic rate down. Despite the fact that they are smaller than aerobic bacteria, they are highly selective, and because of their lower metabolism, it is more difficult for them to create enzymes. These animals have exceptional resistance to environmental stress and can thus live even when their environment changes dramatically.
The advantage of adopting anaerobic bacteria is that you will not be required to have any electromechanical equipment in your system.
Facultative bacteria are capable of flourishing in both the presence and absence of air. When there is enough oxygen available, they can survive by aerobic respiration. When there is no oxygen available, these bacteria convert to fermentation. As a result, facultative bacteria may be described as having the potential to change into either aerobic or anaerobic conditions depending on the conditions in the environment they are exposed to. In most cases, this transition takes a few of hours to complete.
Bacteria such as this require the presence of oxygen in order to thrive. Aerobic bacteria are extremely effective at feeding on organic waste, and as a result, they may be employed to break down trash in high-tech waste-treatment systems. Aerobic bacteria, on the other hand, are extremely sensitive to changes in their surrounding environment. Aspects of their size are likewise greater than those of anaerobic bacteria in most cases. Aerobes have a substantially greater metabolic rate than anaerobes, and this difference is considerable.
Bacteria endospores are a dormant structure that is created by stressed bacteria cells and is used as a protective barrier. They create a protective shell around the cell, which shields it from the impacts of the environment. Endospores can, as a result, endure circumstances that would readily kill any other bacteria, such as high temperatures. These materials can survive extreme pressure, ultraviolet radiation, chemical degradation and other conditions. However, despite the fact that this makes it easier for them to live in the septic tank, they are not particularly effective when it comes to the digestion of organic waste.
- A pathogen is a microbe that is responsible for the transmission of illness.
- The bacteria in the septic tank are responsible for the breakdown of organic waste in the septic system.
- An inadequately functioning system may not be able to effectively remove harmful microorganisms, resulting in groundwater pollution.
- Diseases transmitted by drinking water are caused by harmful bacteria, which are found in abundance.
Septic system owners must consequently examine their systems on a regular basis to verify that they are operating in the manner intended by the manufacturer. Shock therapy should be used promptly if you have a clogged drain field in order to restore it to its normal operating state.
The sludge layer
Heavy materials in wastewater from your home sink to the bottom of your tank, forming a layer known as sludge. When wastewater from your home enters your septic system, it forms a layer known as the sludge layer. Anaerobic bacteria aid in the partial breakdown of the sludge by oxidizing the organic matter. Sludge layers are often composed of mixed biodegradable and nonbiodegradable substances, making it impossible for the bacteria to completely decompose the layer. As a result, septic tanks must be drained on a regular basis, according to the requirements of your provincial legislation.
Applying probiotics to septic systems
At some point, every septic system will fail. Not if, but when will this happen is the real question. The harmful compounds utilized in houses, which ultimately make their way into septic tanks, might be held responsible for this impending breakdown of the system. Despite the fact that there are billions of naturally existing bacteria in the septic tank, these bacteria require a pH level of about 7. The harmful compounds that come from residences interact with the pH levels of the septic tank, resulting in the death of a large number of bacteria in the tank.
It has been suggested that using probiotics to septic systems may be one method of addressing this issue.
Even though there are thousands of different septic tank additives available on the market today, they are not all created equal. Some of them, in fact, will cause more harm than benefit to the septic tank’s environment. Some investigations have revealed that chemical additions can really cause the collapse of a septic system as well as the pollution of groundwater. For this reason, only biological additions such as those provided by Bio-Sol should be used in your recipes. They are created from bacteria and enzymes that have been meticulously chosen, and they inject billions of bacteria into the sewage treatment system as a result of their use.
It is a good idea to add biological additives to your septic tank on a regular basis to ensure that it is operating as effectively as possible.
What happens when feces and urine reach the septic tank?
Excrement from the feces is defined as solid biological waste that is expelled from the large intestine through the anus during defecation by the anus muscle. Feces are eliminated from the body at intervals ranging from three times each day to once every three days, depending on a variety of circumstances. Feces are composed primarily of water with a small amount of solid substance (25 percent). Decomposed microorganisms, indigestible meals, lipids, inorganic particles and protein make up the solid stuff un the environment.
In reality, the activity of bacteria on the bilirubin is what causes the brownish hue of feces to develop.
When the kidneys create urine in order to eliminate waste items from the circulation, they are said to be “urinating.” Urine is yellowish in color and has a variable composition, but the primary components of urine are water and organic solutes, which are excreted in the urine (urea, uric acid, creatinine, hormones, mucins, pigments, inorganic ions, carbohydrates and trace amounts of enzymes).
Urine also contains trace quantities of other chemicals and ions, such as citric acid, ammonia, phosphorus, gluconic acid, and uric acid, amongst other things.
Depending on the individual’s diet and health, the precise value will be established.
The color of urine can also be altered by some disorders, natural substances, and medications. For example, if you consume beets, your urine may become pink or crimson, while this is completely safe.
Feces, urine, and contamination
The majority of pathogens found in wastewater are derived from human excrement. Unlike urine, which is typically sterile, feces contain more than 100 different types of germs and viruses. Although some bacteria are safe, others can cause illnesses such as dysentery, cholera, typhoid, and Hepatitis A. Although some bacteria are harmless, others can cause diseases such as cholera, typhoid, and Hepatitis A. In addition, viruses such as the rotavirus and the Norwalk Agent Virus can induce respiratory infections in susceptible individuals.
There are five major virus groups that originate in human feces, and they are as follows: These are the ones:
- Infections caused by Adenoviruses, Enteroviruses, Reoviruses, Rotaviruses, Hepatitis A, and other viruses
Out of the five types of viruses described above, hepatitis A and rotavirus are the ones that have been shown to be capable of spreading illness. The human gut is home to a large number of different microorganisms. A significant role in the digestion of food is played by certain of these bacteria (for example, Escherichia coli). When certain bacteria, such as salmonella, provide no help to the digesting process, they are nevertheless completely safe while in the colon. However, when they exit the body through feces, they have the potential to spread sickness.
Despite the fact that urine is sterile and does not have any negative health consequences, it is a significant contributor to nutrient contamination of surface water. Nitrates and phosphates are released into the environment when wastewater is not properly treated, allowing them to enter rivers and lakes where they promote the growth of algae. The greater the concentration of these nutrients in water, the larger the algal bloom. As a result, the natural equilibrium of aquatic habitats is thrown out of balance.
Eutrophication is the process by which a river or lake transitions from a clean water body to a lake or river that is oxygen-deficient as a result of an algae bloom.
What happens to urine and feces in the septic tank?
In the wastewater industry, black water refers to wastewater that contains urine and feces. Despite the fact that it also processes greywater, the septic tank was specifically intended for the treatment of blackwater. Greywater is the wastewater that collects in the sinks and showers of homes. Solid particles from human waste, such as excrement and tissue, fall to the bottom of the septic tank, where bacteria devour them. In a normal septic tank, the bacteria do not require oxygen to survive, and as they break down the solid waste into gas and liquid, the tank is said to be functional.
- Meanwhile, the gas generated by the bacteria (mostly hydrogen sulfide, carbon dioxide, and methane) rises to the surface of the water, where it acts as an insulator, allowing the anaerobic conditions to be improved.
- On average, 60-70 percent of the solid trash is liquefied at this point in the recycling process.
- Another layer of sludge forms at the bottom of the tank as a result of the accumulation of particles that are unable to be broken down by the bacteria.
- At this point, pathogens are eliminated from the wastewater by aerobic bacteria, which are involved in the process of respiration.
- A typical system is capable of removing up to 50% of the nutrients present in wastewater streams.
In order to achieve a higher level of effluent quality, it is necessary to build an advanced septic system. This system is more efficient in removing nitrogen, phosphorus, and other nutrients from wastewater before it is recycled back into the water cycle.
Fecal bacteria and viruses are known to cause a variety of ailments, which is why household wastewater must be thoroughly cleaned. Ideally, while the septic system is operating at peak performance, all pathogens should be properly eradicated from the wastewater before it is discharged into the groundwater. However, if the system fails, ground and surface water may become contaminated, putting humans at risk of contracting infectious illnesses. It is therefore critical to do periodic inspections and maintenance in order to avoid this from occurring.
Septic Tank Everything that goes down any of the drains in the house
|Septic TankEverything that goes down any of the drains in the house (toilets, showers, sinks, laundry machines) travels first to the septic tank. The septic tank is a large-volume, watertight tank which provides initial treatment of the household wastewater by intercepting solids and settleable organic matterbefore disposal of the wastewater (effluent) to the drainfield.Function of the Septic TankHow Long Liquids Must Remain In TankSolids StorageAnaerobic DecompositionFlow Into And Out Of The TankEffluent FilterFlow BufferingMicrobes in Septic Tanks Digest, Dissolve, and Gasify Complex Organic Wastes.FUNCTION OF THE SEPTIC TANK While relatively simple in construction and operation, the septic tank provides a number of important functions through a complex interaction of physical and biological processes. The essential functions of the septic tank are to: receive all wastewater from the house separate solids from the wastewater flow cause reduction and decomposition of accumulated solids provide storage for the separated solids (sludge and scum) pass the clarified wastewater (effluent) out to the drain field for final treatment and disposal.Primary TreatmentAs stated, the main function of the septic tank is to remove solids from thewastewater and provide a clarified effluent for disposal to the drain field.The septic tank provides a relatively quiescent body of water where thewastewater is retained long enough to let the solids separate by bothsettling and flotation. This process is often called primary treatment andresults in three products: scum, sludge, and effluent.Scum: Substances lighter than water (oil, grease, fats) float to the top,where they form a scum layer. This scum layer floats on top of the watersurface in the tank. Aerobic bacteria work at digesting floating solids.Sludge: The “sinkable” solids (soil, grit, bones, unconsumed food particles)settle to the bottom of the tank and form a sludge layer. The sludge isdenser than water and fluid in nature, so it forms a flat layer along thetank bottom. Underwater anaerobic bacteria consume organic materials in thesludge, giving off gases in the process and then, as they die off, becomepart of the sludge.Effluent: Effluent is the clarified wastewater left over after the scum hasfloated to the top and the sludge has settled to the bottom. It is theclarified liquid between scum and sludge. It flows through the septic tankoutlet into the drain field.Back to listingsHOW LONG LIQUIDS MUST REMAIN IN TANK Effective volume: The floating scum layer on top and the sludge layer on thebottom take up a certain amount of the total volume in the tank. Theeffective volume is the liquid volume in the clear space between the scumand sludge layers. This is where the active solids separation occurs as thewastewater sits in the tank.Retention time: In order for adequate separation of solids to occur, thewastewater needs to sit long enough in the quiescent conditions of the tank.The time the water spends in the tank, on its way from inlet to outlet, isknown as the retention time. The retention time is a function of theeffective volume and the daily household wastewater flow rate:Retention Time (days) = Effective Volume (gallons)/Flow Rate (gallons per day)A common design rule is for a tank to provide a minimum retention time ofat least 24 hours, during which one-half to two-thirds of the tank volume istaken up by sludge and scum storage. Note that this is a minimum retentiontime, under conditions with a lot of accumulated solids in the tank. Underordinary conditions (i.e., with routine maintenance pumping) a tank shouldbe able to provide two to three days of retention time.As sludge and scum accumulate and take up more volume in the tank, theeffective volume is gradually reduced, which results in a reduced retentiontime. If this process continues unchecked-if the accumulated solids are notcleaned out (pumped) often enough-wastewater will not spend enough time inthe tank for adequate separation of solids, and solids may flow out of thetank with the effluent into the drain field. This can result in clogged pipesand gravel in the drain field, one of the most common causes of septic systemfailure.Back to listingsSOLIDS STORAGE In order to avoid frequent removal of accumulated solids, the septic tank is(hopefully) designed with ample volume so that sludge and scum can be storedin the tank for an extended period of time. A general design rule is thatone-half to two-thirds of the tank volume is reserved for sludge and scumaccumulation. A properly designed and used septic system should have thecapacity to store solids for about five years or more. However, the rate ofsolids accumulation varies greatly from one household to another, and actualstorage time can only be determined by routine septic tank inspections.Back to listingsANAEROBIC DECOMPOSITION While fresh solids are continually added to the scum and sludge layers,anaerobic bacteria (bacteria that live without oxygen) consume the organicmaterial in the solids. The by-products of this decomposition are solublecompounds, which are carried away in the liquid effluent, and various gases,which are vented out of the tank via the inlet pipe that ties into the houseplumbing air vent system.Anaerobic decomposition results in a slow reduction of the volume ofaccumulated solids in the septic tank. This occurs primarily in the sludgelayer but also, to a lesser degree, in the scum layer. The volume of thesludge layer is also reduced by compaction of the older, underlyingsludge. While a certain amount of volume reduction occurs over time, sludgeand scum layers gradually build up in the tank and eventually must be pumpedout.Back to listingsFLOW INTO AND OUT OF THE TANK The inlet and outlet ports of the tank are generally equipped with devicessuch as baffles, concrete tees, or in more recent years, sanitary tees(T-shaped pipes with one short and one long leg).InletsThe inlet device dissipates the energy of the incoming flow and deflects itdownwards. The vertical leg of the tee extends below the liquid surface wellinto the clear space below the scum layer. This prevents disturbance of thefloating scum layer and reduces disruptive turbulence caused by incomingflows. The inlet device also is supposed to prevent short-circuiting offlows across the water surface directly to the outlet.The upper leg of the inlet should extend well above the liquid surface inorder to prevent floating scum from backing up into, and possibly plugging,the main inlet pipe. The open top of the inlet tee allows venting of gasesout of the tank through the inlet pipe and fresh air vents of the householdplumbing.OutletsThe outlet device is designed to retain the scum layer within the tank. Asanitary tee can be used with the lower leg extending below the scum layer.The elevation of the outlet port should be 2 to 3 inches below the elevationof the inlet port. This prevents backwater and stranding of solids in themain inlet pipe during momentary rises in the tank liquid level caused bysurges of incoming wastewater.Typical inlet/outlet teesGas Deflection BaffleGases are produced by the natural digestion of sludge at the bottom of thetank, and particles of sludge can be carried upward by these rising gases.Some tanks have a gas deflection baffle, which prevents gas bubbles (towhich solid particles often adhere) from leaving the tank by deflecting themaway from the outlet and preventing them from entering the drain field.Back to listingsTHE EFFLUENT FILTER In newer systems, there is often an effluent filter: one of the significantimprovements in septic tank design in decades. They range from 4 to 18inches in diameter. As we have described, the most serious problem withseptic systems is the migration of solids, grease, or oil into thedrain field, and the filter is effective in preventing this.A filter restricts and limits passage of suspended solids into the effluent.Solids in a filtered system’s effluent discharge are significantly less thanthose produced in a non-screened system.Back to listingsFLOW BUFFERING The septic tank also provides a buffering of flows between the house and thedrain field. Large surges from the household, such as toilet flushing orwashing machine drainage, are dampened by the septic tank so that the flowsleaving the tank and entering the drain field are at substantially lower flowrates and extend over a longer period of time than the incoming surges.Back to listingsMICROBES IN SEPTIC TANKS DIGEST, DISSOLVE, AND GASIFY COMPLEX ORGANIC WASTES In 1907, W. P. Dunbar conducted tests on the decomposition of vegetable andanimal matter in septic tanks. He stated, “The author has investigated thesubject by suspending in septic tanks a large number of solid organicsubstances, such as cooked vegetables, cabbages, turnips, potatoes, peas,beans, bread, various forms of cellulose, flesh in the form of dead bodiesof animals, skinned and unskinned, various kinds of fat, bones, cartilage,etc., and has shown that many of these substances are almost completelydissolved in from three to four weeks. They first presented a swollenappearance, and increased in weight. The turnips had holes on the surface,which gradually became deeper. The edges of the cabbage leaves looked asthough they had been bitten, and similar signs of decomposition were visiblein the case of other substances. Of the skinned animals, the skeleton aloneremained after a short time; with the unskinned animals the process lastedrather longer. At this stage I will only point out that the experiments wereso arranged that no portion of the substances could be washed away; theirdisappearance was therefore due to solution and gasification.”Back to listings|
How Your Septic System Works
Underground wastewater treatment facilities, known as septic systems, are often employed in rural regions where there are no centralized sewage lines. They clean wastewater from residential plumbing, such as that produced by bathrooms, kitchen drains, and laundry, by combining natural processes with well-established technology. A conventional septic system is comprised of two components: a septic tank and a drainfield, often known as a soil absorption field. It is the septic tank’s job to decompose organic matter and to remove floatable stuff (such as oils and grease) and solids from wastewater.
Alternate treatment systems rely on pumps or gravity to assist septic tank effluent in trickling through a variety of media such as sand, organic matter (e.g., peat and sawdust), constructed wetlands, or other media to remove or neutralize pollutants such as pathogens that cause disease, nitrogen, phosphorus, and other contaminants.
Specifically, this is how a typical conventional septic system works:
- All of the water that leaves your home drains down a single main drainage pipe and into a septic tank. An underground, water-tight container, often composed of concrete, fiberglass, or polyethylene, serves as a septic system’s holding tank. Its function is to retain wastewater for a long enough period of time to allow particles to sink to the bottom and form sludge, while oil and grease float to the surface and produce scum. Sludge and scum are prevented from exiting the tank and moving into the drainfield region by compartments and a T-shaped outlet. After that, the liquid wastewater (effluent) exits the tank and flows into the drainfield. The drainfield is a shallow, covered hole dug in unsaturated soil that serves as a drainage system. Porous surfaces are used to release pretreated wastewater because they allow the wastewater to pass through the soil and into the groundwater. In the process of percolating through the soil, wastewater is accepted, treated, and dispersed by the soil, finally discharging into groundwater. Finally, if the drainfield becomes overburdened with too much liquid, it can flood, causing sewage to flow to the ground surface or resulting in toilet backups and sink backups. Finally, wastewater percolates into the soil, where it is naturally removed of harmful coliform bacteria, viruses, and nutrients. Coliform bacteria are a kind of bacteria that may be found in the intestines of humans and other warm-blooded animals, with humans being the most common host. As a result of human fecal contamination, it is a sign of this.
The Guadalupe-Blanco River Authority has built an animated, interactive model of how a residential septic system works, which you can view here.
Do you have a septic system?
It’s possible that you’re already aware that you have a septic system. If you are not sure, here are some tell-tale symptoms that you most likely are:
- You make use of well water. In your home, the water pipe that brings water into the house does not have a meter. In the case of a water bill or a property tax bill, you will see “$0.00 Sewer Amount Charged.” It is possible that your neighbors have a septic system
How to find your septic system
You can locate your septic system once you have confirmed that you have one by following these steps:
- Taking a look at the “as constructed” drawing of your house
- Making a visual inspection of your yard for lids and manhole covers
- Getting in touch with a septic system service provider for assistance in locating it
Failure symptoms: Mind the signs!
A bad odor is not necessarily the first indicator of a septic system that is failing to work properly. Any of the following signs should prompt you to seek expert assistance:
- Water backing up into the drains of homes and businesses
- It is especially noticeable in dry weather that the drainfield grass is bright green and spongy. The presence of standing water or muddy soil near your septic system or in your basement
- A strong stench emanating from the area surrounding the septic tank and drainfield
Taking Care of Septic Sludge Buildup
Written by aby on September 28, 2017 at 11:28 a.m The water that enters the septic tank contains a diverse range of particles and compounds. As much of the solids as possible is decomposed by aerobic bacteria in the tank; the remainder sinks to the bottom and forms a layer of septic sludge on the bottom. The accumulation of sludge in the tank might cause a variety of major issues.
The problem with too much sludge.
Septic sludge is a typical part of every septic tank’s operation. Aerobic bacteria are unable to digest all of the solid waste that enters the system due to a lack of oxygen. As a result, sludge accumulates in layers on the tank floor. Ultimately, as time goes on, the sludge layer will continue to grow in depth until it eventually overflows. ” If the sludge is not cleaned, it will collect until it ultimately overflows, obstructing the soil absorption area once more.” Water cannot flow into the soil and filter naturally if there is a buildup of septic waste in the drain field.
The water will continue to rise and overflow the drainage area since it has nowhere else to go.
An ounce of maintenance is always best.
The sludge at the bottom of the tank will remain in place until it is pumped out and disposed of properly. Approximately how often should a tank be pumped in order to avoid harmful sludge formation. To calculate the frequency of maintenance, there are a variety of options, including measuring the sludge depth using a do-it-yourself equipment, making an educated guess about the depth based on the number of people who use the system, and consulting with the experts. Have the tank pumped and then ask the technician when the next filling will be necessary.
Keeping the sludge down with added bacteria.
Using a bacterial supplement in the tank between cleanings is the most effective technique to keep septic sludge under control between cleanings. Bacterial additions provide a healthy dosage of additional aerobic bacteria to the tanks, which aid in the decomposition of solid waste. The hard-working bacteria keep sludge levels from increasing too rapidly and generating difficulties in the environment.

Here’s What You Should Do.
Using a bacterial supplement in the tank between cleanings is the most effective technique to keep septic sludge under control in between. Aerobic bacteria that digest solid waste are provided by bacterial additives, which provide a healthy dose of additional aerobic bacteria to the tanks. The hard-working bacteria keep sludge levels from increasing too rapidly and generating difficulties in the environment.

Do septic additives really work?
Many homeowners are attempting to improve the efficiency of their septic systems by adding additives, such as Rid-X, to give the bacteria in their tanks a small boost. Bonus points for being aware of your septic system! Maintain your zeal, though, for something a bit more constructive. In order for the bacteria in your tank to function correctly, it must have a broad biome of bacteria. That tiny package (whether it contains yeast, Rid-X, or another organism) will only provide a small amount of biodiversity to the system.
Due to the minimal number of bacteria or enzyme contained in an additive dosage when compared to the amount of bacteria already present in a tank, the additive dose provides little, if any, help in wastewater digestion.
It is possible to have too much of a good thing.
Maintaining a septic tank does not need extensive knowledge of chemistry.
Every 2-4 years, this layer of sludge must be removed from your system by a sludge pump. The bacteria in your septic system are excellent at breaking down particles and slowing the building of sludge, as long as the system is kept in a properly balanced environmental state.
Are septic additives worth it?
In a nutshell, the answer is no. The needless expenditure of additives will “ADD” up in the long run. (Please accept my apologies for the dad joke.) Keep the extra coin in case you want to tip the pump truck driver. When comparing tanks with and without bacterial additions, one research revealed no variation in the sludge level between the two groups (McKenzie, 1999).

Septic system maintenance for the enthusiastic homeowner…
For those meticulous homeowners who want to take home a gold medal in septic tank care, we’ve compiled a non-exhaustive list of tasks for you to do. Pumping your tank on a regular basis is the most effective maintenance procedure.
The best way to maintain a septic system
The liquid in a septic tank should look like this: A maintenance item that isn’t your standard squeaky-clean item: This is what liquid septic waste looks like after it is disposed of.
- Review ourMaintenance Suggestions for more information. Avoid introducing harsh chemicals into your system, such as bleach, paint thinners, insecticides, gasoline, antifreeze, and the like, because they can damage the bacteria that is responsible for keeping your system running correctly. If your house has a septic system, you should avoid using garbage disposals because they flood the system with organic materials that are too difficult for the microorganisms in the septic tank to break down. Inorganic items such as feminine hygiene products, kitty litter, cigarette butts, and paper towels should never be flushed down the toilet. They fill your septic tank with substances that are not biodegradable
- Check out our options for septic system laundry
- Keep track of how much water you’re putting into your system and preserve it wherever you can to keep costs down. When possible, combine loads of laundry and only run your dishwasher when it is completely full. The use of grey water (water from the washing machine, dishwasher, baths and showers) to flood your septic system and drain field to the point of exhaustion will interfere with the bacterial composition of your septic tank and drain field. Prevent dangerous compounds from being flushed down the toilet. Use the appropriate rubbish transfer station to properly dispose of chemicals such as solvents, paint, varnish, oil, and insecticides
- Cooking oil and fat should not be flushed down the sink. Drainage and runoff water should be diverted. Pools and hot tubs should never be drained into your septic system or drainfield. To keep water input to your drainfield to a minimum, downspouts and roof runoff should be directed away from your drainfield. Reduce the amount of water you use! When feasible, fix leaks and replace old, inefficient toilets, faucets, and showerheads with new, more water-efficient models. Only use the washer and dishwasher when there are full loads. Additionally, it reduces the cost of water and electricity bills, while also extending the life of the septic system.

Septic Tank Bacteria: What You Need to Know
In the case of a new septic tank owner, or if you’re just not familiar with the way your septic tank operates, you may not be aware of the importance of bacteria and how it affects your septic tank’s operation. Bacteria contributes to the proper operation of your septic tank over time. Your septic tank would most certainly jam up very fast if there were no microorganisms present. By following proper septic tank management procedures, you may encourage the growth of beneficial bacteria. The way you utilize your septic tank, as well as the items you flush down your drains, can have an influence on how well it functions.
Why Is Septic Tank Bacteria Important?
Solid waste is continuously drained down the drain to the septic tank. Whenever solids are introduced into the tank, they sink to the bottom and accumulate there. Over time, such sediments will begin to accumulate in the sewer system. In order to prevent this, the tank must be pumped every three to five years since the solids in the tank always ascend to the top of the tank. If the solids reach the drainfield pipe, which is located towards the top of the septic tank, microscopic particles will be released into the drainage system.
Bacteria reduces the amount of bacteria that accumulates at the bottom of the tank.
Beneficial bacteria floats about in your septic system, breaking down solid waste and converting it to liquid waste. Whenever the liquids in the tank reach the drainfield, they are securely discharged into the yard and do not become clogged.
What Can You Do to Promote Septic Tank Bacteria Growth?
Septic tanks inherently contain bacteria that will develop and multiply. By draining more solid waste down into the tank on a consistent basis, you encourage the growth of bacteria. However, there are several things you can do to your septic tank that will help to slow the spread of germs. All of the items meant to kill bacteria such as antibacterial soaps, bleach, antibiotics, and other products designed to kill bacteria have the potential to enter your tank and harm some of the beneficial bacteria in your tank.
It is possible that you may need to alter the way your family operates in order to prevent flushing these items down the toilet.
Before washing soiled garments, soak them in vinegar for a few minutes, and mix baking soda into your laundry detergent before putting it in the machine.
If you require a secure location to dispose of your medication, consult with your doctor to determine where you may properly dispose of your medication waste.
Do You Need to Put Bacteria In Your Septic Tank?
Some firms manufacture bacteria that may be added to your septic tank in order to support good functioning of the system. However, if you follow the instructions to the letter, microbial additives should not be required. Assuming you keep the amount of bacteria-killing agents and chemicals in your drains to a minimum, your tank should have enough bacteria to perform its functions. Whether or not you decide to employ septic tank bacteria, you should check with your local sanitation authorities to see if any chemicals or other materials are prohibited from being flushed down the toilet.
If you’re not sure which septic tank bacteria firms are the best, ask the specialist who pumps your septic tank for a suggestion.

Septic System Information and Care
When municipal sewer service is not available, a septic system that has been properly constructed and maintained is an excellent option for treating wastewater and protecting groundwater quality. A typical septic system is comprised of two key components: the septic tank and the drainfield (or leach field). Waste from toilets, sinks, washing machines, and showers is channeled into a septic tank, which is a holding tank that is typically constructed of pre-cast concrete or fiberglass and is proportioned according to the projected wastewater flow from a given-sized house or commercial establishment.
- In the first stage of wastewater treatment, anaerobic bacteria (bacteria that can survive in an oxygen-free environment) break down solids into liquids and generate gas that is vented through the building’s plumbing vent stack.
- The lack of oxygen inside the septic tank also has the added benefit of deactivating some of the disease bacteria that are prevalent in sewage.
- Because it allows aerobic (oxygen-using) bacteria to continue deactivating the disease germs that remain in the wastewater, the drainfield serves as a secondary treatment facility for sewage.
- Evaporation of water also occurs through the layer of soil that surrounds the drainfield.
- That way, enough permeable or unsaturated soil is available to filter the wastewater before the remainder of it gets into the groundwater table and underlying aquifer.
- In certain instances, modern wastewater treatment systems that “aerate,” or add oxygen to the wastewater, may be necessary to treat the effluent.
Others are equipped with chlorinating chambers or peat moss-based filtering chambers, which kill disease germs before they may infiltrate into groundwater supplies.
Septic System Care
When municipal sewage service is not available, a properly designed and maintained septic system is an excellent option for treating wastewater and protecting groundwater quality. The septic tank and drainfield are the two basic components of a conventional septic system. Sewage from toilets, sinks, washing machines, and showers is channeled into the septic tank, which is a holding tank that is typically constructed of pre-cast concrete or fiberglass and is proportioned according to the projected wastewater flow from a given-sized house or commercial establishment.
When anaerobic bacteria (those that can survive in an oxygen-free environment) are used to perform the first stage of treatment on wastewater, they generate gas that is vented through a vent stack in the building’s plumbing system and break down the particles into a form that can be disposed of.
Drainfields are often composed of a series of perforated pipes or slotted panels that are frequently covered by a layer of gravel, tire chips, or other lightweight materials, such as styrofoam pieces, to carry away the liquid component of wastewater from the septic tank to the drainfield.
As water is drawn downhill through the soil layers of the drainfield, it also serves as a filtering system for wastewater.
Septic systems must be elevated above the ground surface in some regions due to the presence of certain soil types such as clay layers or bedrock, as well as the presence of a shallow seasonal high water table (“mounded” systems).
It is possible that typical septic systems will not be suitable in some situations, such as flood zones near rivers or other bodies of water.
Other modern wastewater treatment methods may include chlorinating chambers or peat moss-based filtering chambers, which are designed to kill disease germs before they reach groundwater levels.
