How it Works – Household wastewater is flushed or washed through the exit pipe into the septic tank. Heavy solids sink to the bottom. Over 24-48 hoursthe solids break down to form a sludge layer. Lighter floatable solids, such as grease, oils, and fats, collect at the top of the liquid in the tank to form a scum layer.
- The bacteria that live in the septic tank constantly break down solid waste.The tank’s fittings hold the scum and sludge from flowing out into the drainfield.
- Liquid that is washed or flushed into the tank is known as effluent.
- In the tank, effluent is partially treated or “clarified” by bacteria.
- As the tank fills up, the liquid empties into the drainfield, where it is absorbed into the soil.
The liquid drains through the soil layers, where bacteria filter and digest contaminants. By the time the wastewater reaches groundwater, it is fully treated.

How often do you need to clean 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. Alternative systems with electrical float switches, pumps, or mechanical components should be inspected more often, generally once a year.
Household size Total wastewater generated Volume of solids in wastewater Septic tank size
Does shower water go into septic tank?
Everything you flush down the toilet and send down the sinks, showers and washing machine or dishwasher ends up in your septic tank system.2. Wastewater flows from the house to the septic tank. The solids and scum form sludge in the tank and this needs to be removed regularly.
Can toilet paper be flushed with a septic tank?
Will Too Much Toilet Paper Harm My Septic Tank? What are people doing with all that toilet paper they’re hoarding? You may wonder the effects of flushing heaps of paper down the toilet might have on your septic system. While many of you are at home using more of your resources than usual, you might not even think about the fact that your toilets and septic tanks may not be ready for the extra traffic coming its way.
Constant usage of toilets connected through septic systems can eventually lead to clogging, even under seemingly normal conditions. But when you’re home all day and flushing toilet paper every couple of hours, it can take a toll on your entire system and lead to an overflow. And your family might flush things down the toilet that shouldn’t be flushed, such as paper towels or certain other products that can clog up your tank.
Toilet paper is always septic safe. As long as you’re flushing regular, designated toilet paper, your tank should remain fine. Problems arise when you flush huge wads of toilet paper all at once — or often throughout the day. To avoid stopping up your septic system with toilet paper or any other organic matter you’ve been flushing, use a product that will dissolve away matter inside your tank and prevent a backup. A great product is, which will eliminate the organic matter inside your tank. It contains beneficial enzymes that will break down toilet paper, hair and more without damaging your pipes or your septic system. It’s perfect for restoring and maintaining the bacterial balance of your septic system and will also rid your drains of any foul smells caused by clogging.
What happens when septic tank is full?
What does a full septic tank mean? – It’s very typical for a septic tank to be full, which means it’s functioning normally! But there is a standard full range, and then there is the possibility your septic tank is clogged or overfull, both of which are not good.
There are three different ranges your septic tank system could be running at: 1. A full tank means that it is running at a normal full level. This means that the intake and outtake pipes are functioning normally, and wastewater is flowing into the septic system’s absorption or drain field. A pumped tank doesn’t mean that the tank stays empty.
Once you start using your septic system again, it will return to the proper full level.2. The tank can become full because it’s clogged with sludge. When this happens, the liquid/wastewater still flows from the outflow pipe to the drainage area, but the undissolved toilet paper or waste doesn’t break down.3.
What gets pumped out of a septic tank?
How Often Are Septic Tanks Emptied, and Where Do the Contents Go? A typical residential septic tank is usually about 4 feet wide (1 meter) by 8.0 feet (2 meters) long by 6 feet (1.8 meters) tall. Jupiterimages/Getty Images Wherever there are a lot of people operating their homes’ waste systems on, you can bet you’ll find plenty of local businesses that specialize in removing the scum and sludge that accumulate in the tank over time.
- This is an important service; if too much sludge builds up, it can lead to overflow, which is bad for everybody.
- Generally, commercial septic pumping involves a pump truck removing the sludge, effluent and scum in the tank, then leaving the tank empty and ready to be filled again.
- Once the waste is removed, there are only so many things that can be done with it.
Before that restrict septic sludge dumping, waste companies could simply bury it in dump sites. As it became clear that sites like these were a health hazard, they were outlawed. These sites remain, though many are in the process of remediation (cleanup).
These days, federal and state laws govern the final destination of the contents of your septic tank. In some cases, the septic contents are taken to waste treatment plants and added to the stew piped in from a municipal sewer system or delivered to independent, for-profit companies specializing in the treatment of septage.
Septage may also be dumped in approved, The guidelines concerning septage dumping are strict and sites can be few and far between, however. Because of the dilemma posed by disposing of your septic tank’s contents, septage is often used in another way: to grow your food.
Unless there’s a “” label on it, it’s possible the food on your table was grown using the sludge that used to be in your septic tank as fertilizer. This use of septage can be a controversial one. Proponents, including many, say it’s a win-win situation, since municipalities don’t have to worry what to do with the waste, and farmers get cheap fertilizer for their crops.
If applied correctly to cropland with good soil and a low water table, the soil should act as a filter in the same way a drain field does in the backyard of a home with a septic tank. It is a contentious subject and the use of biosolids in agriculture continues to come under fire as a potential health and environmental threat.
The practice can be seen as an effective way to recycle waste, but there are scientists and health professionals who that the use of biosolids in agriculture is dangerous for the nation’s farmland and is creating a number of health risks. There’s another, more cutting-edge way septage is being used these days — generating to power homes.
It’s long been known that the methane produced as a waste product in the breakdown of sewage could be used to generate electricity. While methane is a simple fuel, it can also be broken down and used to generate electricity using located on-site at treatment plants.
What happens if you don’t clean your septic tank?
Consequences of Not Pumping Your Tank – Your septic tanks must be pumped daily to keep them functioning properly. In case the tank is not pumped, then after a point of time, the solids will build up in the septic tank, and the holding capacity of the drain field will get affected.
Not maintaining the septic tank can result in backups, eventually leading to septic system failure. Scum and sludge in your septic tank could accumulate and move to the drain field if you don’t pump it frequently. This will clog the drain field, preventing wastewater from being treated, and wastewater may back up into the house or form a pond in the yard. Organic debris might fill the leach field if your septic tank is not frequently drained. This will harm you and your loved ones, contaminate your pipes, and spread several diseases.
It depends on the size of the tank and the volume of wastewater the household produces. Hence, most homeowners must pump their septic tank every three to five years.
Can I use a dishwasher with a septic tank?
Yes, you can! Septic tank owners ask can you have a dishwasher and septic tank? a dishwasher and septic tank setup is perfectly safe. However, just as you would with your toilet, sink and other drain usage, you’re going to need to be cautious about what you send down the pipes. Yes, You can have a dishwasher And Septic Tank! A few years homeowners had concerns regarding dishwashers and septic tanks. This was mainly due to the chemical formulations of dishwater tablets people were using in their dishwashers. As you may know, bacteria in septic tank systems really do not like chemicals.
Some care is required in order to conserve the good bacteria to ensure that you don’t kill them off! For this reason, dishwashers and septic tanks have received some bad rap over the years with some septic tank users choosing to avoid using dishwashers altogether and instead choosing to simply scrub up at the sink.
However, there’s really no need – it’s actually pretty safe to go right ahead and use a dishwasher and septic tank. However, before you go ahead and put dishes in, have a quick read through our guide below – we’ll fill you in on most things you need to know about using dishwashers and septic tanks together.
How do you empty a septic tank?
How are Septic Tanks emptied? When septic tanks approach their max capacity the waste must be emptied as to continue normal waste removal. This is done by using a waste removal vehicle which has a large pressurised vacuum attached to a hose which sucks up the sewage into the vehicles waste tank.
An engineer will gain access to the septic tank and insert the vacuumed hose into the septic tanks holding area. When the nozzle of the vacuum is submerged in the waste the pump is activated to increase pressure forcing the waste to rise up the pipe and begin filling the waste removal tank. The size of the waste removal tank will depend on the company that you book the septic tank emptying with.
You need to know the approximate amount of waste that is contained in your septic tank before booking so an appropriate vehicle can be booked to remove your waste. Once the Septic Tank is empty or the waste removal vehicle is full, the sewage will be transported to an approved storage and treatment facility.
How do I clean my septic tank naturally?
Simple, Quick Cleanse – This method is a quick, gentle solution that is also effective. This method requires one to utilize the power of baking soda, vinegar and lemon. First start by mixing a quarter of a cup of Baking soda with a half cup of vinegar and put directly into toilet.
Then add two tablespoons of Lemon juice. The baking soda combined with the vinegar causes a chemical reaction that fizzles and helps break down grim and dirt. The lemons acidity aids in this process and also provides a pleasant aromatic. This solution is will clean your toilet bowl and after flushed, will do the same to the pipes within your system.
And since this is a natural solution, it won’t affect your systems healthy bacteria.
Can hair go in a septic tank?
Hair. Flushing the hair from your hairbrush down the drain or flushing the hair from the catcher in your shower catches down the drain, may seem like an easy way to deal with excess hair. However, that is not how you should deal with hair. Hair contains proteins which the bacteria in your septic tank cannot break down.
Is all laundry detergent septic safe?
What features to look for in a laundry detergent for septic systems? – When looking for a laundry detergent suitable for use in septic systems, it is important to look for the following features:
- Low levels of phosphates: Phosphates are a major source of pollution in lakes and streams, so look for detergents that contain minimal amounts.
- Mild ingredients: Many harsh chemicals used in regular laundry detergents can be damaging to septic tanks and other natural ecosystems. Choose one with mild, natural ingredients instead.
- Biodegradable formula: Make sure that whatever product you choose should break down quickly after being released into the environment.
- High efficiency (HE) compatible: If you own a high-efficiency washing machine, look for a detergent formulated specifically for HE machines.
- Low sudsing: Detergents that produce too many suds can cause clogs and damage to septic tanks, so opt for one with low or no sudsing.
By following these tips, you can be sure to choose the best laundry detergent for your septic system. With the right product, you can keep your septic system healthy and your clothes clean.
How long does toilet paper take to decompose in a septic tank?
How Long Does It Take Toilet Paper To Decompose? – It might not be as quick and efficient as you think, think how often septic systems get blocked up due to toilet tissue. In most cases, it can take as little as one month, perfect, right? Well, in the wrong conditions it could take anywhere in between one and three years for it to fully decompose. It’s crazy to think little sheets of paper could take that long to decompose. But, as I said, it all depends on varying factors:
The thickness of the tissue How much water is available The weather conditions it’s exposed to
Like I mentioned before, biodegradable paper products are all designed to break down quicker than your standard soft toilet rolls. Although all toilet paper decomposes, eventually, there is a more pressing question we need to answer:
Why won’t my toilet flush after septic pumped?
If you are still getting backups in your bathroom piping after having pumped the septic tank, there can be only two problems. The first is a blockage of the inside pipes leading from the fixtures to the septic tank. Drains can become blocked with sludge, roots and dirt from broken pipes.
- The first thing to do is to have your pipes professionally cleaned so you can be assured the pipes are fully open.
- If the technician encounters a problem, he can run a camera down the line and find out if the roots have created a problem with the line or if the septic tank is functioning properly.
- If you have a septic tank cleaning service clear the lines and pump the tank and it’s still not working properly, then the drain field is having a problem.
In addition, if the ground is saturated because of high water table or heavy rainfall, then the septic tank will not drain and it will back up into the house. A drain field can act as a spreader of the effluent or it can act as a collector of rainwater and groundwater.
- When the sludge layer at the top and the bottom inside septic tank get high enough to leave the septic tank and go out into the drain field, it will plug up your drain field.
- The sludge in septic tanks forms a layer below the pipes and prevents the water from leeching into the ground.
- The same type of biodegradable matter that decomposes and falls to the bottom of a lake is what keeps the water from leeching into the aquifer.
National septic standards recommend that septic tanks be pumped every three years to prevent this problem. Once a drain field fails, you only have a few options. One is a completely new drain field and the other is to add more branches to the existing drain field and increase your capacity.
How long does it take for a septic tank to be full?
A properly designed septic tank system will have a septic tank with sufficient volume to accumulate solids for several years. Over time the solids accumulate and begin to fill up the septic tank. If these solids are not periodically pumped out, suspended solid particles may begin to flow into the absorption field.
- These solids will eventually clog the absorption field and may require the installation of a new absorption field.
- Newer septic tank systems are required to have an effluent filter located on the outlet of the septic tank.
- The purpose of this filter is to protect the absorption field by trapping suspended solids.
If the septic tank is not pumped out periodically, the effluent filter may become clogged causing wastewater to back up into the house. A specific determination of when it’s time to pump a septic tank can be made by having the depth of the solids and level of scum buildup checked periodically.
- New septic tanks have an access port over the inlet and outlet tees to facilitate the cleaning of the effluent filter and pumping of the tank.
- Two factors primarily affect the pumping frequency required.
- The first factor is the holding capacity of the septic tank.
- The more people using a system, the faster the solids build up, and the more frequently the tank will have to be pumped.
A larger capacity system provides better treatment and requires less pumping. The standard three or four bedroom house has a 1000 gallon septic tank. The second factor is the amount of solids in the wastewater. If you have a garbage disposal, you will have to pump out your septic tank more frequently.
The use of a garbage disposal may increase the amount of solids in a septic tank by as much as 50%. Pouring grease or other non-biodegradable types of solid waste drown the drain will add to the accumulation of solids. Homes with garbage disposals are required to increase the size of their septic tank by 50%.
A three or four bedroom house with a garbage disposal is required to have a 1500 gallon septic tank. The recommended pumping frequency for pumping out septic tanks can be estimated based on assuming a wastewater retention time of 24 hours and assuming that 50% of the solids are digested by bacterial action in the tank.1.
- How often should I pump my Septic tank? A: On average, every two years depending how many people live in the house.2.
- Why do Septic systems fail? A: Because of lack of maintenance and due to build up of sludge and deposits.3.
- Why do I need certification? A: Certifications are required for real estate transactions.
They are outlined as requirements to obtain certain types of home loans. They exist to protect the buyer from purchasing “unserviceable” property. Also, they are outlined as requirements to obtain certain types of home loans in escrow items.4. Where are septic tanks located? A: Usually 12-18 inches underground and normally 5 – 10 feet from the house (varies).5.
How long do septic tanks last? A: Typically between 15 – 20 years.6. How fast will a septic tank fill up? An empty septic tank will usually fill up in less than 10 days. THE CALCULATION IS: 50 GALLONS OF WATER PER DAY PER PERSON AVG HOUSE IS 3 PEOPLE 3 PEOPLE X 50 GALLONS = 150 GALLONS PER DAY FOR 3 PERSON FAMILY TANK CAPACITY IS 1000 GALLONS LESS THAN 7 DAYS but don’t worry this is NORMAL.7.
If I had my tank pumped 15 years ago, why is it overflowing in less than a month? The system is starting to fail. Septic tanks should be pumped every 2 years as maintenance to ensure a long life for the system ( a long life is 50years). Septic tanks are notmeant to overflow since they are pumped every 2 years.
Systems that are overflowing require immediate repair and attention. Further detail: A septic system is an ecological system that requires regular maintenance every 2 years to ensure performance. Maintenance is pumping every (2) years to remove soilds that have accumulated in the septic tank and monthly bacterial treatments.
Once a system is overflowing it is no longer digesting water; hence it’s overflowing. Overflowing systems must be replaced according to your local jurisdictions requirments. CLICK HERE EMAIL US YOUR QUESTIONS

4 Ways to Protect Your Septic Tank While Doing Your Laundry If your home relies on a septic tank system, you may have heard horror stories about catastrophic flooding caused by washing machines. Fortunately, most modern septic systems are entirely capable of handling wastewater from your washing machine, but irresponsible use can still cause serious problems in septic tanks and lines.
Erring on the side of caution will help to prevent washing machines from causing serious damage to your septic system. Keep the following guidelines in mind to ensure that your septic tank can handle everything your washing machine throws at it.1. Use Detergents and Soaps Correctly You might assume that throwing an extra dose of detergent in with your laundry is harmless, but excessive detergent use can cause serious damage to septic systems.
Septic tanks rely on colonies of beneficial bacteria, which consume and process organic waste so it can be safely released into the tank’s drain field. Most laundry detergents contain cleansing chemicals, such as phosphates and surfactants, which can destroy these vital bacteria and prevent the tank from processing waste effectively.
Under normal circumstances, detergents are diluted in the laundry water to the point where they will not harm the bacteria, but using too much detergent can expose the bacteria to lethal levels of these chemicals. Using too much detergent can be especially harmful if you rely on detergent powders. Using too much laundry powder will cause the undissolved powder to clump together inside your septic system.
If these clumps of powder get caught in the system’s inflow lines, they can cause serious blockages, which may lead to sewage and wastewater backing up into your home. As long as you use the correct amount of detergent with each laundry load, you shouldn’t encounter any of these problems.
- However, if you want to play it safe, choosing liquid laundry detergents that do not contain phosphates, bleach, or nonylphenol ethoxylate (the most common surfactant found in laundry detergent.) 2.
- Clean Lint Filters Regularly Cleaning your washing machine’s lint filter regularly is particularly important for washing machines used with septic systems.
If the lint filter becomes clogged, clumps of lint can escape into the septic system and may cause serious clogging if they get caught in the septic lines. Lint that makes it into the septic tank system can also cause issues. Any non-organic fibers in the lint, such as threads from polyester or nylon clothing, will not be processed by the tank’s bacteria and will settle in the bottom of the tank.
- Over time, accumulated lint and other indigestible matter can form a thick layer of impacted material inside the tank, reducing its overall capacity.3.
- Don’t Overload the System Washing machines use a lot of water, and doing many loads of laundry in quick succession can overwhelm your septic tank system.
If too much wastewater flows into the tank in a short space of time, the tank may be forced to release waste into the drainfield before it has been processed. This can cause serious problems with drainfield clogging and contamination, which are usually expensive to repair.
The amount of laundry you can do in a day will depend largely on your septic tank’s holding capacity. If your tank is relatively large, you should be able to wash several average-sized loads in a day without causing problems. However, older septic systems tend to have smaller tanks, so you should space out your laundry loads if you live in an older home.4.
Consider a New Washing Machine Another way to avoid overwhelming your tank with laundry water is by investing in a newer washing machine. Modern washing machines must meet strict energy efficiency regulations, and use a lot less water than older models.
They can be expensive, but a newer washing machine will allow you to do laundry more frequently without worrying about septic system problems. Follow these simple rules, and you should have no issues using your washing machine alongside a septic tank system.

How long do septic tanks last?
The average life expectancy of a septic tank – The life expectancy of a septic tank can vary according to many different factors, from the environment that it is being kept in, to the material that it is made from. Generally speaking, a septic tank should last for between about 15 and 40 years.
Should a septic tank always be full of water?
Help! My Septic Tank is Full! | Van Delden We often receive calls about “full” septic tanks. But what does full really mean? A septic tank should always be “filled” to its normal liquid level, or the bottom of the outlet pipe which carries effluent to the absorption area. This normal liquid level is usually between 8″ to 12″ from the top of the tank on average (see picture at right).
- If the liquid level is at bottom of the outlet pipe, then one would assume the absorption area is accepting the household wastewater.
- If the liquid level in a septic tank is above the outlet pipe, or to the top of the tank, we call it “overfull” because the tank is filled above its normal operating level.
If the tank is overfull, this is usually a sign of problems with the absorption area.
How deep is a septic tank?
While septic tanks may not be excellent conversation starters at dinner parties and other social gatherings, but they are an essential part of any establishment or house. Septic systems are underground wastewater treatment structures that treat wastewater generated by bathrooms, drains, and laundry plumbing. Photo Courtesy: Unsplash Standard Size of Septic Tanks in the Philippines If your home’s septic tank is too small for your needs, it can’t to handle the amount of waste. This can cause problems like foul odors, flooding, and blocked pipes. You will also have problems if your septic tank is too large.
- Without the right volume of wastewater flowing through it, a septic tank that is too large will not function properly.
- If your septic tank is too huge for your home, you won’t have enough liquid needed to create the bacteria that helps the septic tank break down solid waste.
- The three chamber septic tank will measure 3.1 meters (10 feet) by 1.9 meters (6 feet) and will be 2.1 meters deep (almost 7 feet).
Septic tanks are usually rectangular and measure about 5 feet by 8 feet in size. Septic tank components, including the lid, are usually buried between 4 inches and 4 feet underground in most circumstances.

RELATED: 10 Useful Types of Pipes and the Latest Plumbing Innovations Factors to Consider When Determining the Size of Your Septic Tank Here are some criteria that go into choosing septic tank sizes; keep them in mind as you hunt for the best septic tank for your home and business.
Toilet Water Use
The toilet accounts for a sizable portion of the wastewater produced. Consider the number of times each individual flushes the toilet each day to get a better picture of water usage. On average, each person is expected to flush four times. The amount of water used by the toilet is also significant.
Bathroom Water Usage
Bathing is necessary, and this adds to wastewater production. You’ll need to figure out how many showers each member of the family takes on average to get a sense of how much water they use. A single shower per day may be plenty for some. Others have several showers.
Dishwashing also consumes or adds a significant volume of water to the septic tank. The amount of times you hand wash dishes each day is one detail to be concerned about. It’s also crucial to know how long it takes for water to run while dishes are being washed in minutes.
Waters Taps Use
Water taps are used for several reasons, ranging from brushing your teeth, shaving, face washing, and so on. As a result, data on the number of times each household member uses the water tap is required. It could take anything from a minute to several minutes for the tap to be used each time. As a result, offer statistics on the average number of minutes that such taps run with each use.
If you have a lawn, you probably water it daily. Add information on how many times per week you irrigate your lawn. When assessing water use, the time spent watering is also significant. It will also be required to give data on how frequently you use your outdoor water taps.
Laundry is one of the main sources of water in a septic tank. To figure out how big a septic tank to put in, you’ll need to know how much water you use for laundry. The amount of loads carried out by each household member every week is factored in. On average, each household member should do roughly 7 loads of laundry every week.
It’s also important to consider the type of washing machine you have. Top-loading washers use roughly 50 liters of water per load. RELATED: 8 Most Common Plumbing Problems and Plumbing Tools Different Septic Tank Design Septic system design and size can vary widely from neighborhood to neighborhood, and even across the country, due to a lot of considerations.
Aspects to consider include household size, soil type, site slope, lot size, proximity to sensitive water bodies, weather conditions, and even municipal legislation. The ten most common septic system types are listed below.
A watertight underground tank constructed and built to receive and partially treat raw sanitary wastewater from households. Heavy solids sink to the bottom of the tank, while grease and lighter materials float to the top. They discharge the wastewater to the drain field for additional treatment and dispersal while the sediments stay in the tank.
A decentralized wastewater treatment system comprises a septic tank and a trench or bed subsurface wastewater infiltration system (drain field). A typical septic system is commonly built in a single-family home or small business.
For over 30 years, gravel-free drain fields have been widely used in several areas, and they have largely replaced gravel systems as a standard technology. Examples include open-bottom chambers, fabric-wrapped tubes, and synthetic materials such as expanded polystyrene media. Gravel-free systems can be created using recycled materials, lowering carbon emissions significantly.
Drip Distribution System
Drip distribution is a method of effluent dispersal that can be used in several drain fields. The drip distribution system does not require a large mound of dirt because the drip laterals are inserted into the top 6 to 12 inches of soil. The disadvantage of the drip distribution system is that it demands the installation of a large dosage tank after the septic tank in order to transfer wastewater to the drip absorption region in a timed dose.
Aerobic Treatment Unit
Aerobic Treatment Units (ATUs) use many of the same procedures as municipal sewage plants, but on a smaller scale. An aerobic system is used to inject oxygen into the treatment tank. The additional oxygen increases natural bacterial activity in the system, which aids in the subsequent treatment of nutrients in the effluent.
Mound systems are an option in areas with shallow soil depth, strong groundwater, or shallow bedrock. The sand mound has a drain field trench built into it. The effluent from the septic tank is pumped into a pump chamber, where it is dosed and pushed to the mound. As the wastewater flows into the trench, it is cleaned and filtered through the sand before being dispersed onto the native soil.
Recirculating Sound Filter System
Sand filtration systems can be installed above or below ground. The effluent from the septic tank is piped to a pump chamber. It is then pumped to the sand filter. The sand filter is commonly built of PVC or a sand-filled concrete box. Effluent is pumped at a low pressure via the pipes at the top of the filter.
In evapotranspiration systems, drain fields are unique. The evapotranspiration system’s drain field is lined with a waterproof substance. The effluent evaporates into the atmosphere after entering the drain field. Unlike traditional septic system designs, the effluent never filters into the soil and never reaches groundwater.
Decentralized wastewater treatment system that collects wastewater from two or more households or buildings and delivers it to a treatment and dispersal system placed on a suitable site near the shared ownership dwellings or structures. In places like rural subdivisions, cluster systems are common.
Septic tanks last for years.
A septic tank can last several years if it is properly maintained and pumped regularly. It’s important to get the right professional to maintain the tank regularly and prevent clogs and other issues.
Septic tanks are cheaper option.
Installing new pipes to eliminate wastewater via a public sewage system is typically more expensive than using a septic tank. If your property is more than an acre, a septic tank will be a more cost-effective choice. The price of installing a tank depends on where you live, the sort of system you need, and the size of the tanks you need.
Septic tanks are environmentally friendly.
Septic tanks have a lesser environmental impact since they use the soil’s natural filtering process to clean wastewater. You are helping to restore the water table beneath your property by using a septic tank. Recycling wastewater on your property guarantees that the local water table is always replenished, which is beneficial to the vegetation and wildlife.

Why don’t septic tanks smell?
What causes septic odor near the septic tank? – Some of the factors that might contribute to septic tank odors near the tank are ineffective digestion in the tank, a septic tank that is full and due for pumping, or loose septic tank covers that are causing the leaking of septic odor.
- Sulfate-reducing bacteria are also associated with septic odors, specifically hydrogen sulfide.
- Sulfate-reducing bacteria are naturally present in most septic tanks.
- These bacteria obtain energy through the oxidation of organic compounds and they do this as they reduce sulfate to hydrogen sulfide hence their name, sulfate-reducing bacteria.
Septic odors are normal for any well-functioning septic tank. As the anaerobic bacteria break down the organic waste, carbon dioxide, hydrogen sulfide, and methane gases are released. Hydrogen sulfide has a foul smell that would easily be detected by the human nose.
However, we rarely smell it because these gases remain tightly shut within the septic tank. If the septic cover gets dislodged or damaged, the odors will escape and the odors will be smelt near the septic tank. If the drainfield gets clogged, the septic system will fail and that might lead to the emission of septic odors.
Although full tanks often have septic odor problems, there are many septic system owners who still battle with these odors even after pumping their tanks. The surest way of dealing with this is using biological additives which include a buffer that can help in organic waste digestion.
Are long showers bad for septic systems?
Avoid Showers that Last More than Twenty Minutes – It is not recommended to take showers that are longer than twenty minutes. If you take a long shower, it can send too much water into your septic tank for it to handle. This will make it work harder and will likely result in overflowing with wastewater.
How do you know when a septic tank needs emptying?
Excess water or an unpleasant smell around the drain field – The field where your tank empties is a place you should make regular checks on – if there are pools of water (although do be conscious of recent weather conditions) or unpleasant smells, these are signs of a full tank.
