After septic tanks have been used for six months or more, the tank should have developed three layers: a scum layer on top, a clarified effluent in the middle which is free of large solids, and a sludge layer on the bottom.
- The septic tank has a scum layer on top and a sludge layer in the bottom. You need to remove the scum and sludge layer, so that you have the cleanest water going to the septic field. We use backflushing to get the maxium amount of sludge out of the tank.
What does the scum layer look like in a septic tank?
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 water surface in the tank. Aerobic bacteria work at digesting floating solids.
What are the 3 layers in a septic tank?
The contents of the septic tank stratify into three layers: • Floating Scum Layer – soaps, greases, toilet paper, etc. Liquid layer – water, other liquids, and suspended solids • Sludge – heavy organic and inorganic materials settle to the bottom of the tank.
What happens to scum layer in septic tank?
Septic tanks are mainly settling chambers. They allow time for solids and scum to separate from the wastewater, so clear liquid can safely go to the drainfield. Over time, the scum and sludge layers get thicker, leaving less space and time for the wastewater to settle before passing to the drainfield.
What is the sludge layer in a septic tank?
Sludge – The bottom layer of your septic system is made up of a material called sludge. Sludge is comprised of byproducts of the decomposition of other wastes that are dealt with by your septic tank. Heavy materials that sink to the bottom of the septic tank also become part of the sludge.
How do I check the sludge 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.
How do you remove scum from a septic tank?
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 floats on top of septic tank?
Heavy solids, such as dirt and digested waste, will sink to the bottom of the tank to form the sludge layer. Meanwhile, solids that are lighter than water, such as grease, hair, and toilet paper, will float to the top to form the scum layer.
What causes crust in septic tank?
If there is a solid, thick (over one inch) crust on the top, it should be pumped out with the rest of the tank contents. Thick crusts may be the result of excessive soap, grease or fats put down the drain.
How do you dissolve sludge in a septic tank?
One is to inject air into the tank to try and mix the contents and break down the solids. The more common method is to use a mechanical mixer that acts somewhat like a baking mixer where the contents are mixed until they form a slurry that can be withdrawn by the vacuum pump.
What are the signs that 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 thick should the sludge layer be in a septic tank?
Septic tanks need to be pumped out when the sludge layer exceeds 24 inches in depth or when the bottom of the scum layer is less than 3 inches above the Page 2 lower end of the submerged outlet. If you cannot locate the submerged outlet, clean the tank if the scum layer is more than 12 inches thick.
What Are the Septic Tank Layers? – Septic Maxx
Millions of people in the United States still have septic tank systems linked to their residences. Do you understand how your septic system works, despite the fact that they are so common? Despite the fact that you may not be employed in the septic system sector, it is critical that you grasp the primary components of your septic system as well as its fundamental operations. Even a rudimentary grasp of how your wastewater system works may help you keep repairs to a minimum and extend the life of your wastewater system.
Scum, sludge, and effluent are the three layers of wastewater that make up your septic tank: scum, sludge, and effluent.
Spillage: Spillage is the solid material that accumulates at the bottom of your septic tank, forming an unsightly coating on top of the water.
Anaerobic bacteria that grow at the bottom of your tank and feed off of the sludge layer can be found in the tank bottom.
- Scum is a term used to describe a collection of material found in a septic tank that are lighter than water.
- Most of the floating solid waste items float to the surface of the water, where aerobic bacteria begin to work, digesting the bulk of the floating solid waste materials.
- A large portion of the liquid in your septic tank is composed of this substance.
- In order for your septic system to work effectively, these layers must remain balanced and maintain an appropriate retention duration throughout time.
- In order for your tank to function effectively, it must have a minimum retention time of twenty-four hours.
- In most cases, clogged drainfields are the most prevalent reason for a sewage treatment system to fail.
- It is completely natural and has been particularly formulated to assist in replenishing the beneficial bacteria and protease in your tank in order to guarantee adequate drainage into your drainfields.

What are the Septic Tank Layers?
Sludge, effluent, and scum are the three layers of wastewater that make up your septic tank: sludge, effluent, and scum. You will have a perfectly functioning septic system when each of these wastewater layers is correctly balanced. As a homeowner, you should become familiar with the indications that indicate when the sludge layer has become overburdened and when your septic tank needs to be drained.
What Are The Three Layers of Wastewater?
- Scum is the substance that makes up the top layer of the septic system. When items like soap byproducts and cooking oils reach the top of the wastewater tank, they create this scum. Effluent is the wastewater that remains in the intermediate layer of the septic tank after the scum has risen to the top of the tank and the sludge has sunk to the bottom of the tank, which is known as the effluent layer. In certain cases, it may contain minute particles of waste items. When your septic system is operating properly, the effluent/water is released into the drain field from the tank
- However, this is not always the case. In your septic system, sludge makes up the lowest layer, which is made up of a substance known as sludge. In your septic tank, sludge is made up of byproducts of the breakdown of various waste materials that have been disposed of in the tank. Heavy items that sink to the bottom of the septic tank become a part of the sludge as a result.
Pumping the sludge out of your tank on a regular basis is essential for keeping your septic system in excellent operating order.

Receive Notifications Septic tanks allow gravity to separate materials from wastewater because heavier particles settle while fats, grease, and other lighter solids float, allowing heavier solids to be removed from the wastewater. Particles removal in a septic tank is often thought of as occurring predominantly through settling, although separation of suspended solids by flotation is also extremely significant in the tank’s operation.
- The presence of fats, oils, and grease in the wastewater helps to improve the flotation process because they congeal on the surfaces of tiny particles, making them more buoyant and floatable in the water.
- After six months or more of usage, septic tanks should have established three layers: a scum layer on the surface, a cleared effluent layer in the center that is free of big particles, and a sludge layer at the bottom of the tank.
- A scum layer should be present, albeit it may be a thin zone of an inch or less in thickness, or it may be a bigger coating depending on the methods used within the house or facility.
- The effluent baffle’s aim is to ensure that the scum layer remains in the septic tank and should be replaced as soon as possible if it has been removed or has become inefficient.
- The design detention period for a septic tank should be lengthy enough to allow for appropriate suspended particles and oil/grease removal by sedimentation and flotation.
- Third, there should be little to no turbulence in the septic tank in order to allow settleable particles to build at the bottom and floatable solids to accumulate at the top.
In little, typical doses, they should not be an issue, but when used excessively, additives such as powerful phosphate-based cleansers, fabric softeners, and degreasers can have an adverse effect on scum development and cause it to build more quickly.
In addition, greater water temperatures and higher water flow rates aid in the mechanical emulsification of lubricating oils.
The influence of the microbial community – A healthy microbial community is required for the septic tank to function correctly.
This covers any product found in a house that has the ability to destroy microorganisms.
Ideally, the pH level should be in the range of 6-8, which is close to the pH of tap water.
Low pH levels are caused by acidic substances such as cleansers or furnace condensate, whilst high pH values are generated by basic substances such as basic cleaners or other chemicals.
This has been observed when regeneration water from water softeners enters septic tanks.
It may be possible to help by routing the recharge out of the system or by replacing outdated units that require much more salt.
When there is no scum layer, you should collaborate with the property owner to identify the potential causes of the problem and take steps to correct them in order to extend the life of downstream components.

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.

Inspecting Your Septic Tank
|Firstuncover and remove the first manhole cover. Some systems have”risers”that make this job easier by bringing the tank lids up to the ground surface. (We encourage you to have risersinstalled so you won’t need to dig down each time you inspect.)The diagram at left shows the top of the two most common septic tank configurations. The upper figure is found onnewer tanks and the bottom one is usually found on older septic tanks. In most cases, the hole to the left is thefirst compartment, the hole to the right is the second compartment, and the rectangular cover is to the crossoverbaffle. (Some tanks, 25 years or older, may have only one compartment that is round, oval, or square.)This procedure determines the thickness of the scum level(SC).|
- In order to make the scum stick, One of the PVC pipes was cut down to 6 feet from its original length of 10 feet. Glue a 90-degree elbow on one of the ends. Create an elbow out of a 6-inch piece of PVC tubing and glue it in place. End caps should be placed on the open ends. Place a board or a stick over the top of the hole, manhole, or riser to prevent water from leaking in. As shown in Figure 1, lower the scum stick down the manhole of the first compartment of the tank until it rests on the top of the scum layer (see Figure 1below), and mark the scum stick where it passes the reference point (A). Work the stick through the scum layer, starting at the elbow end and working your way down. Continue pushing straight through the scum layer, turning the stick 90 degrees, and pulling up on the stick until you feel the bottom of the scum layer. Note where the scum stick crosses the reference point (B) with a marker. Removing the scum stick and measuring the distance between the two markings will get the following results. This is the measurement of the thickness of the scum layer (SC).

Remove the covers from the inlet, outlet, and crossoverbaffles on the ducting system. Examine the baffles to confirm that they are still present and that they are not significantly rusted. Venting holes should be present and unobstructed if the baffles are made of concrete and are molded into the rest of the tank’s structure.
- Ensure that the intake baffle is unobstructed and that the pipe is properly sealed to the tank
- Ensure that the exit baffle is unobstructed and that the liquid level is at the bottom of the pipe, rather than below or above the bottom of the pipe. The line connecting it to the tank must be completely sealed. PLEASE NOTE: In the following photo, looking down an output baffle, the effluent is below the pipe, suggesting a faulty seal. Additionally, the crossover baffle should be clear of blockage.
- This means the input baffle should be clear and the pipe should be completely sealed to the tank
- This also means that the exit baffle should be clear and the liquid level should be at the bottom of the pipe, not below or above it. Pipe connections to tanks must be properly sealed. PLEASE NOTE: In the following photo, looking down an output baffle, the effluent is below the pipe, suggesting a faulty seal
- The crossover baffle should be free of obstructions as well.
Septic Tank Problems, Part One: A Healthy Septic Tank
“I have no idea why I’m having septic tank troubles; I’ve never even had to pump my tank before,” a common complaint among homeowners. as though this was evidence that their septic system had been functioning well before abruptly failing. However, keep in mind that most failed septic systems have been in problems for one or more decades before the first indicators of trouble show up.

However, keep in mind that most failed septic systems have been in problems for one or more decades before the telltale indications surface.
- 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. In the tank, this scum layer floats on top of the water’s surface and collects bacteria. Aerobic bacteria are involved in the digestion of floating particles. Effluent is the cleared wastewater that remains after the scum has risen to the surface and the sludge has sunk to the bottom of a wastewater treatment plant. It is the clear liquid that exists between the scum and the sludge layers. It exits the septic tank and enters the drainfield
- It is a natural occurrence. A layer of sludge is formed at the bottom of the tank as the “sinkable” materials (dirt, grit, bones, and unconsumed food particles) settle to the bottom of the tank. Because sludge is denser than water and fluid in nature, it settles to the bottom of the tank in a thin, flat layer. Underwater anaerobic bacteria devour organic components in the sludge, emitting gases as they do so, and eventually die and become a part of the sludge as they die off.

Troubleshooting Septic Tank Issues, Part Two: The Issues Begin Troubleshooting Septic Tank Issues, Part Three: Drainfield Issues
How your septic system works
A septic tank and a drainfield are the two main components of a septic system. Water from your home is channeled into your septic tank, where heavy sediments sink to the bottom of the tank and produce a layer of sludge on the bottom of the tank. Grease, toilet paper, and other light substances float to the surface and accumulate to produce a scum layer on the surface of the water. Between the sludge and the scum is a semi-clear layer of wastewater known as effluent, which contains no particles and is located between the two layers.
Bacteria living in the soil purify wastewater by devouring dangerous bacteria and viruses before the wastewater seeps into the groundwater table.
These layers will ultimately require the services of a professional septic pumper to be removed.
In order to properly maintain and check your septic system, you must first identify the sort of system that you have, as well as the needs for particular maintenance and inspection.
The gravity system is the most frequent variety since it does not require the use of a pump to function. Pressure distribution systems, sand filter systems, mound systems, and aerobic treatment units such as the Glendon BioFilter system are examples of other types of systems.
How to Measure Septic Tank Sludge Depth
What is the best way to determine when to pump your septic tank? In a previous piece, you learned that the only way to know for certain when to pump your septic tank is to take an actual measurement of the amount of accumulated sludge and scum in the tank. It is designed such that the septic tank should be pumped when the combined sludge and scum layer displaces 30% of the tank’s total volume. Using the above example, if the liquid depth of the tank is 48″, the tank should be pumped when the combined thickness of the sludge and scum layer measures 14 12″ (48″ X 0.30).
An example of this would be a long hollow plastic tube with a check valve at the bottom of it.
- The scum layer should be pushed through until it is almost broken through by the sludge judge. Mark on the tube in a visibly obvious manner the link between the top of the scum layer and the spot on it. Pulling the tube up and measuring the length of the tube are two options. In many cases, you may see part of the scum layer adhered to the tube to help you locate it
- This is normal.
The following are the measurements for the sludge layer:
- Slowly lower the tube into the septic tank until it comes into contact with the tank’s bottom
- And With each gradual pull of the gadget out of the water, the check valve shuts, allowing a liquid/solid profile of the septic tank water to be captured. It is possible to determine the thickness of the sludge layer
The collected sludge inside the tube measured around 8″ – 9″ in diameter, and there was no scum layer present in this specimen. The thickness of the scum layer would simply be added to the 8′ – 9″ measurement if there was one. In this particular instance, the scum/sludge layer combined displaces approximately 18 percent of the tank volume (8 12″/48″ in this case). Upon further investigation, it was discovered that this septic tank had last been drained 26 months before. The septic tank should be pumped within 43 months of the last septic tank pump out, based on this date (0.18 / 26 months X 0.30 = 43 months) of the last pump out.
- Even if the cost of $75 for a sludge judge is beyond of reach for you, you may construct your own gadget that will do the same function.
- The length of the stick will vary depending on how deep your septic tank is buried.
- The idea here is to avoid wrapping it too tightly around the stick’s handle.
- Pay close attention to the link between the top of the scum layer and the placement on the sticking stick.
- The scum layer is often adhered to the stick to help you locate it, and this is a good way to identify the location.
- Continue to slide the stick back and forth in a plus (+) pattern for approximately 2″ in each direction to enable the solids to flow through the cheesecloth slowly and softly.
Measure the witness line of solids that are lodged into the cheesecloth to determine the amount of solids present. Measure the distance between the “wet” mark on the upper end of the stick and the bottom of the stick. Calculate the percent capacity in the same way as in the previous example.
How to Care for Your Septic System
Septic system maintenance is neither difficult or expensive, and it does not have to be done frequently. The maintenance of a vehicle is comprised of four major components:
- Inspect and pump your drainfield on a regular basis
- Conserve water
- Dispose of waste properly
- And keep your drainfield in good condition.
Inspect and Pump Frequently
Inspection of the ordinary residential septic system should be performed by a septic service specialist at least once every three years. Household septic tanks are normally pumped every three to five years, depending on how often they are used. Alternative systems that use electrical float switches, pumps, or mechanical components should be examined more frequently, typically once a year, to ensure that they are in proper working order. Because alternative systems contain mechanical components, it is essential to have a service contract.
- The size of the household
- The total amount of wastewater produced
- The amount of solids present in wastewater
- The size of the septic tank
Service provider coming? Here is what you need to know.
When you contact a septic service provider, he or she will inspect your septic tank for leaks as well as the scum and sludge layers that have built up over time. Maintain detailed records of any maintenance work conducted on your septic system. Because of the T-shaped outlet on the side of your tank, sludge and scum will not be able to escape from the tank and travel to the drainfield region. A pumping is required when the bottom of the scum layer or the top of the sludge layer is within six inches of the bottom of the outlet, or if the top of the sludge layer is within 12 inches of the bottom of the outlet.
In the service report for your system, the service provider should mention the completion of repairs as well as the condition of the tank.
An online septic finder from the National Onsite Wastewater Recycling Association (NOWRA) makes it simple to identify service specialists in your region.
Use Water Efficiently
In a normal single-family house, the average indoor water consumption is about 70 gallons per person, per day, on average. A single leaking or running toilet can waste as much as 200 gallons of water each day, depending on the situation. The septic system is responsible for disposing of all of the water that a residence sends down its pipes. The more water that is conserved in a household, the less water that enters the sewage system. A septic system that is operated efficiently will operate more efficiently and will have a lower chance of failure.
- Approximately 70 gallons of indoor water are consumed by each individual in a normal single-family house on a daily basis. A single leaking or running toilet can waste as much as 200 gallons of water each day, depending on how often it occurs. Septic systems collect and treat all of the water that a household sends down its pipes. When a family conserves water, less water is discharged into a storm drain or into the septic tank. Improved septic system performance and reduced failure risk are two benefits of water conservation. With the Environmental Protection Agency’s WaterSense program, you may conserve water in a variety of ways and buy goods that are more water-efficient.
Properly Dispose of Waste
Everything that goes down your drains, whether it’s flushed down the toilet, ground up in the trash disposal, or poured down the sink, shower, or bath, ends up in your septic system, which is where it belongs. What you flush down the toilet has an impact on how effectively your septic system functions.
Toilets aren’t trash cans!
Your septic system is not a garbage disposal system.
A simple rule of thumb is to never flush anything other than human waste and toilet paper down the toilet. Never flush a toilet:
- Septic systems are not meant to be used as garbage disposal systems. A simple rule of thumb is that you should not flush anything other than human waste and toilet paper down the toilet. Never flush a toilet if you can help it
Toilet Paper Needs to Be Flushed! Check out this video, which demonstrates why the only item you should flush down your toilet are toilet paper rolls.
Think at the sink!
Your septic system is made up of a collection of living organisms that digest and treat the waste generated by your household. Pouring pollutants down your drain can kill these organisms and cause damage to your septic system as well as other things. Whether you’re at the kitchen sink, the bathtub, or the utility sink, remember the following:
- If you have a clogged drain, avoid using chemical drain openers. To prevent this from happening, use hot water or a drain snake
- Never dump cooking oil or grease down the sink or toilet. It is never a good idea to flush oil-based paints, solvents, or huge quantities of harmful cleansers down the toilet. Even latex paint waste should be kept to a bare minimum. Disposal of rubbish should be avoided or limited to a minimum. Fats, grease, and particles will be considerably reduced in your septic tank, reducing the likelihood of your drainfield being clogged.
Own a recreational vehicle (RV), boat or mobile home?
When dealing with a clogged drain, stay away from chemical drain openers if possible. To prevent clogging, use hot water or a drain snake; Don’t ever flush cooking oil or grease down the toilet. It is never a good idea to flush oil-based paints, solvents, or huge amounts of harmful cleansers down the toilet. We should strive to reduce even latex paint waste. Disposal of rubbish should be eliminated or limited to a minimum. In turn, this will dramatically limit the quantity of fats, grease, and sediments that enter your septic tank and eventually block its drainfield; and
- The National Small Flows Clearinghouse’s Septic System Care hotline, which may be reached toll-free at 800-624-8301, has a factsheet on safe wastewater disposal for RV, boat, and mobile home owners and operators.
Maintain Your Drainfield
It is critical that you maintain the integrity of your drainfield, which is a component of your septic system that filters impurities from the liquid that emerges from your septic tank once it has been installed. Here are some things you should do to keep it in good condition:
- Parking: Do not park or drive on your drainfield at any time. Plan your tree plantings so that their roots do not grow into your drainfield or septic system. An experienced septic service provider can recommend the appropriate distance for your septic tank and surrounding landscaping, based on your specific situation. Locating Your Drainfield: Keep any roof drains, sump pumps, and other rainfall drainage systems away from the drainfield area. Excess water causes the wastewater treatment process to slow down or halt completely.
Septic Tank Maintenance
Among rural residents, the septic tank-soil absorption system is the most often encountered wastewater treatment method. The septic tank is responsible for removing particles from wastewater, while the soil absorption field (drain field) is responsible for filtering, treating, and disposing of the septic tank effluent. The removal of particles from wastewater helps to keep the drain field from becoming clogged and failing prematurely. The septic tank also serves as a storage facility for settled solids and as a biological digestion facility for part of these materials.
How Does a Septic Tank Work?
- By collecting wastewater in the tank and allowing particles to settle and scum to rise to the surface, the septic tank eliminates solids from a home’s drainage system. In order to improve settling, it is recommended that incoming water be retained in the tank for at least 24 hours. Up to 50% of the solids will disintegrate into liquids and gases during the process. All of the leftover particles collect in the tank, and no biological or chemical additions are required to help or speed the settling or decomposition of the materials. The flushing of solids other than human waste and white toilet paper should be avoided as a general rule of thumb. With continued usage of the septic system, sludge continues to collect at the bottom of the septic tank’s tank. Tanks that have been properly designed have enough capacity to last for three to eight years before they need to be serviced. Every year, beginning with the third year, the tank should be examined to assess how much sludge is there. Because both the entrance and the exit are located at the top of the tank, it is critical to remember that septic tanks always seem to be completely filled. Identifying how much of the tank’s volume is being consumed by solids, scum, and sludge is essential for the homeowner. When solids, such as sludge and scum, account for more than 35 percent of the tank’s capacity, the tank must be pumped to remove the solids.
Servicing a Septic Tank
Too much sludge and scum is allowed to collect in the septic tank, and the incoming sewage does not have enough time to settle the solids before it enters the sewer system. A buildup of solids in the drainfield can cause it to clog, which can result in sewage overflowing to the ground surface, where it can expose humans and animals to the disease-causing organisms present in sewage. It is critical to inspect the tank and get it maintained as needed in order to avoid this from occurring. When a full tank is not pumped, it is possible that the drainfield will not fail quickly.
This leads to inefficiencies in the drainfield and the possibility of groundwater pollution as a result.
The frequency with which the tank is pumped is determined by the size of the tank as well as what and how much is flushed down your drains.
The state of Oregon requires a 1,000-gallon septic tank to be installed for residences with up to four bedrooms.
A system that serves a household of two would require pumping every six years if the identical system served a family of four. Systems that were established prior to the implementation of the current laws and regulations may have smaller septic tanks and require more frequent pumping.
Cleaning the Tank
- The Department of Environmental Quality (DEQ) licenses septic tank pumpers who are able to properly pump and clean your tank. If possible, have someone else supervise the cleaning in order to guarantee that it is done correctly. Known as “septage,” the material that is pumped out of the tank must first be broken up, and then mixed up to dissolve the sludge layers that have formed on the surface of the liquid section of the tank in order to remove the whole amount of material. This is commonly accomplished by pumping liquid from the tank and injecting it back into the tank’s bottom. The septic tank should be drained out through the huge central service hole, not the sanitary tee or baffle inspection ports, according to the manufacturer’s instructions. Tanks that are pumped out through the inspection ports may suffer structural damage. Before shutting the tank, inspect the tees and baffles to ensure they are in good working order. If they are missing or in poor condition, sanitary tees should be used in their stead. Never go into a septic tank unless absolutely necessary. Replacement of baffles or repair of the tank should be carried out from the exterior of the tank. When working on a septic tank from the outside, ensure sure the location is adequately aired and that someone is nearby to supervise you. Septic tanks emit deadly fumes that may kill a person in minutes. Never enter a septic tank to rescue someone who has been overtaken by poisonous fumes or a lack of oxygen unless you are using a self-contained breathing device to protect yourself. It is best to call for emergency service and to place a fan on top of the tank to allow fresh air to circulate. To make cleaning and inspection easier, install a watertight riser and a gasketed cover from the central service hole at least one inch above the surface prior to burying the tank
- This will allow for easier cleaning and inspection. It is not necessary to bury the riser cover.
How to Get Further Information
The DEQ’s septic system program is administered by a number of counties. Further information on who to contact in a given county or on the Department of Environmental Quality’s program may be obtained by contacting theDEQoffice closest you or by calling toll free in Oregon 800-452-4011.

Septic system maintenance should be performed on a regular basis. It is important to keep your system in good working order so that it can provide a safe and legal method of waste disposal for your home’s plumbing system. Proper maintenance will also guarantee that the system remains healthy and operating for a long period of time. When it comes to septic system ownership, the more knowledgeable you are and the more familiar you are with the operation of your septic system, the more equipped you will be to take care of it.
This system is composed of three major components: This is the location to which all liquid waste flows as it exits your house through your plumbing system, which is the pipe that is run throughout the walls and crawl area of your home.
Septic tanks are available in a variety of sizes.
If you have any issues about tank sizes, you should consult the South Carolina State Regulations.
Often referred to as the cake, the first or top layer is fittingly dubbed the scum layer due to its thick consistency.
A layer of scum, also known as cake, floats on top of the main layer, which is basically waste water known as effluent.
The scum layer becomes thicker and the sludge layer becomes deeper as time passes.
This is why it is critical to do septic tank pumping and cleaning on a regular and consistent basis.
Gravity is used to transport the effluent from your septic tank to your distribution box once it has exited the tank.
It has multiple holes in it where your drain field pipes are connected, and these holes are where your distribution box gets its name.
A complex of subterranean, perforated pipes lies beneath the surface of your drain field, which is covered with gravel.
Your drain field is a critical component of your septic system’s operation.
Also, keep in mind that parking on or driving over your drain field area can cause irrevocable damage to your septic system, resulting in expensive septic system repairs.
If you are unclear about the location of any components of your septic system, we strongly recommend that you call us for a septic system check.
