Although I didn’t believe it at first, the claim that powdered detergents are terrible for septic systems has come up twice in the last few weeks, and I had to conduct some research to support my doubt after hearing it both times. What did I learn as a result of my research? A common misconception among septic system owners is that powdered detergents (such as laundry and dishwashing detergents) can block their tanks. This is really a MYTH, to a degree. After doing some research, I discovered that there is no difference between powder and liquid detergents; rather, it is a difference between natural/biodegradable components and chemical/petroleum based chemicals.

It is necessary for the specialists to provide a more thorough explanation before propagating this MYTH.

If you are unfamiliar with septic systems, here is some background information.

Water, pH, and bacteria must be in the proper balance in a septic system in order for it to function properly.

  • Even though I didn’t believe it at the time, the notion that powdered detergents are harmful to septic systems has come up twice in the last couple of weeks.
  • Was it a surprise to learn what I learned?
  • However, this is a MYTH, to a certain extent.
  • It’s also about the fillers and additives, as previously stated.
  • Consumers should look a bit further into the contents of their cleaning products since labels and marketing materials for cleaning products may be deceptive and difficult to understand.

Let’s speak about it. Surfactants Surfactant is an abbreviation for surface active agent. Surfactants are substances that aid in the removal of debris from a surface. Surfactants can be classified as either natural/biodegradable or man-made/chemical. This was surprising to me since I had assumed that the term surfactants meant something negative and that it was a warning indication to keep away from that particular product. The chemical compound washing soda is classified as a surfactant in its pure state.

I’m glad there’s more chemistry!

Those of you who have already made the transition to natural cleaning and body care products may have noticed a reduction in the amount of suds in your life, as well as the fact that you and your house are just as clean and happy without all of the foamy activity.

Septic System Safe Laundry Detergents

The usage of a septic system for water and sewage disposal is common in the United States, with over 25% of houses employing one. It is essential to understand how a septic system works in order to follow best practices in the home goods that you use to keep it in good working condition. Most of us don’t consider about septic tanks until there is an issue, which is typically not until it is too late. A septic tank is a tank that collects and treats all of the wastewater generated by households that are not linked to a public wastewater system.

Laundry Tips for Healthy Septic Systems

Laundry provides a significant amount of water to the whole system. Here are a few pointers to keep in mind in order to avoid problems: Try to limit yourself to no more than one or two loads of laundry every day if possible. Even if you have a normal washer that takes a big quantity of water for each load, it is preferable to spread out a week’s worth of laundry across many days rather than doing numerous loads on a single day. If at all feasible, replace your old conventional top-loading washer with a new high-efficiency top-loading or front-loading washer.

  1. To maintain the health of the system, laundry wastewater should not be discharged directly into the septic system drain field; instead, it should be discharged into the septic tank.
  2. Normal quantities of detergents and bleaches can be used in the septic tank without causing any disruption or harm to the bacterial action.
  3. Surfactants derived from nonylphenol ethoxylate are found in several laundry detergents.
  4. If these chemicals are not treated appropriately in a septic system, they can pose a major threat to groundwater and surface water quality in the surrounding area.

The cost of septic tank friendly laundry products might be higher than that of conventional detergents. A dry well should be installed next to the sewer line if you are establishing or updating a septic system and wish to use different detergents instead of the standard household detergents.

While using the proper laundry detergent might help to keep a system healthy, you must still be attentive in order to keep your septic system operating at peak performance. The tank must be emptied on a regular basis and utilized in the right manner.

Laundry Tips for Healthy Septic Systems Continued…

Powdered detergent has the potential to cause blockages in septic systems, slowing down the processing speed of the septic tank and, in severe circumstances, completely blocking a drain. Excessive quantities of filler or carrier can be found in less cost powdered laundry detergents. Some of the fillers may be montmorillonite clay, which is a kind of clay that is used to seal soils. When washing clothes, the ideal approach is to use liquid laundry detergent or a single-dose detergent pod that does not contain fillers that might hurt the system.

Alternatively, you can put a lint filter in the drainage line of your washing machine if you frequently suffer blockages in the drainage pipes of your septic system to the drainage field.

Installing a dry well to collect laundry greywater is an option to consider.

When it comes to installing greywater irrigation systems, many municipal systems in drought-prone areas provide lessons and discounts on the necessary hardware and supplies.

Selecting a Laundry Detergent for a Healthy Septic System

Based on the sort of septic system you have in place, you may choose which laundry detergent is the most safe to use. If you want to utilize a typical, gravity-powered system, liquid laundry detergents are the best choice. However, if you have an aerated septic system, a powdered septic tank friendly laundry detergent is a preferable alternative since it will prevent excessive foam in the aerated septic system. Surfactants should be kept to a bare minimum in septic tank friendly detergent. In addition, the label should state whether or not the detergent is biodegradable.

14 Best Septic Safe Laundry Detergent in 2021

Almost every homeowner is confronted with the challenge of providing a system for cleaning his or her rural house, particularly in circumstances where there is no local central sewer. In such instances, an autonomous system is given, in which the reservoir serves as a holding tank for wastewater and serves as a treatment facility for the wastewater.

As a result, septic tanks are becoming increasingly popular as a remedy. However, there are a few things you should be aware of in order to ensure that your cleaning system runs well. This article will also teach you about goods that are safe for use in septic tanks.

What Is a Septic System?

The septic tank is the final destination for all of the sewage. It is completely sealed and includes anaerobic microorganisms that are specifically designed to digest wastewater. Therefore, contaminants are recycled into sludge that settles at the bottom and water that is fully free of impurities and suited for technical applications. However, the process of purification is not yet complete. In the other tank, the water passes through a second step of filtration before being released. Aerobic bacteria that are “alive” in this environment filter the water once again.

Useful Hints to Keep Your Septic Safe

Thekitchn It is not enough to simply follow a list of septic-safe cleaning products in order to ensure that the septic system operates properly. There are various guidelines that must be followed when using a washing machine or dishwasher. Here are only a few examples:

  • Always attempt to turn on the machines when you have enough items (dirty linens or dishes) to fill a complete load of laundry
  • If it is not absolutely required, limit yourself to one washing cycle every day. You can use a brief cycle to clean simply a few items if you still need to clean them. When purchasing a washing machine or a dishwasher, look for models that have water-saving capabilities. Always make an effort to use the smallest amount of detergent that is reasonably practical
  • Do not use detergents that may interfere with the operation of a septic tank.

What laundry detergent is safe for septic systems?

ProfsnabvlWhile chlorine-containing detergents are far less costly, repairing the microflora of the septic tank will be significantly more expensive. The use of a septic-safe detergent will help to extend the life of your cleaning equipment. Cleansers that are suitable for use in the home can be split into two categories:

  • A phosphate powder or gel has a clear detrimental influence on the environment: phosphates entirely destroy calcium ions, which allows active surfactants to perform their functions. Part of the bacteria is killed by phosphate-containing chemicals, which reduces the overall efficacy of the entire purification system. Because of this, it is preferable to avoid using this sort of cleaner if you have a septic tank
  • Cleaners that are devoid of phosphates and chlorine can be used in septic tanks, but the higher surfactant content has a negative impact on the microenvironment as well. So make an effort to pick such goods, but keep an eye out for surfactant concentration that is less than 5 percent.

What Chemical Substances Are Prohibited for Septic Systems?

It is never recommended to drain or flush harsh chemicals into an autonomous sewage system. They have the potential to be harmful to bacteria. As a result, try to stay away from things like:

  • Chlorine in its purest form, as well as chlorine-containing compounds and detergents
  • Substances and products containing surfactants in excess of 5% of the total surfactant content Fluids containing phosphates and petrochemicals (kerosene, gasoline, engine oils, paints, solvents, fuels and lubricants, cadmium)

How to Keep Your Septic System Healthy

If you own your home, you are probably well aware of the need of keeping your septic system in good working order. The introduction of soap suds, liquid laundry detergents, and clothing fibers into the system increases the likelihood of it being damaged significantly. Even natural remains such as plant bits, vegetables, or coffee beans might pose a hazard to our septic system! Owners of such a system frequently claim that it emits an unpleasant stench as a result of the same reason. Because of this, it is advised that frequent checks and cleaning be included in the maintenance schedule.

1. Inspect the system

This will entail frequent inspections for proper upkeep as well as the preservation of records.

2. Pump out the septic tank regularly

Every one to three years, it is advised that you perform this to remove the suds and product remains from the drain field; otherwise, there is a great chance of the drain field being clogged.

3. Conserve water and monitor its usage

Septic systems can back up when we discharge more water into them than what is suggested by the manufacturer.

4. Use laundry detergents reasonably when washing clothes

When we use an excessive amount of liquid laundry agents and other laundry detergents, both powdered and liquid, there is a considerable chance that the bacterial equilibrium of the system will go out of balance.

The same is true for any type of substance that will be introduced into the system, such as bleaches, cleansers, and so on.

5. Never deposit non-decomposable items into the sewer

It is possible that the suds or an excessive amount of liquid laundry detergent will be harmful, but cooking fats, tea leaves (and other natural products), tissues, wet-resistant paper towels, and even cigarette butts will not decompose and there is a high likelihood that they will eventually plug the entire system.

6. No grease running down the drain!

The use of any fatty substance, natural or not, can either clog the pipes or cause an accumulation in the septic tank itself. It is far preferable to dispose of them in a separate trash can from the rest of the rubbish.

How to Make the Septic System Less Smelly?

  • Tips for Septic System Owners on Keeping Their Home Clean
  • Have you ever noticed that the odor coming from your septic system is foul? Perhaps this is due to the fact that it hasn’t been cleaned in quite some time! In part because the septic system contains microorganisms that digest natural materials and create a by-product that helps maintain the right pH level, the pH acidity level gradually climbs over time as these microscopic “assistances” are unable to handle all of the waste. It is at this point that the odor becomes noticeable. It is possible to just use a household solution to cure the system, but don’t worry, we have some excellent tips to get it back up and running quickly.
  1. Baking soda is an excellent natural slimming agent. Pour one cup of this product down the drain or into the toilet once a week to ensure that the pH level of the septic system is maintained at the right level. Another natural preventative strategy is to dump a gallon of boiling water down the drain once a week. Don’t go overboard with the water. Additionally, the excess liquid will help to wash away the soda more quickly, as well as pushing all of the waste out of the tank that hasn’t been digested
  2. Keep an eye on what you’re flushing down the toilet. If it’s suds, it’s more or less alright
  3. Nevertheless, plant pieces, plastic or paper materials, and other such stuff must be disposed of properly in the garbage. Insist on a qualified cleaning service. It is far preferable to engage a qualified septic tank cleaning service to remove the collected trash rather than attempting to do so yourself, since the results will be far better. When performed incorrectly, this type of cleaning might cause more harm. Don’t flush any liquid paints or cleaning solutions down the toilet, as they will cause a buildup of gunk on the pipes’ walls and eventually cause a blockage in your plumbing system.

Washing Clothes Safely With a Septic System

Waldemar Brandt captured this image. Many of us are unaware that the manner we wash our clothing (and the laundry detergents we use, of course) has a significant impact on the performance of our septic tank. Follow these basic guidelines to ensure that your septic tank is in peak operating condition.

  • Wash your clothes at least twice a week. Due to the fact that an excessive volume of liquid would exhaust the system, it is preferable to one completely filled wash. Liquid washing detergent is the best option. When cleaning garments, use liquids instead of powders since they are safer for the drain field. When washing garments, avoid using excessive amounts of bleach or laundry detergent. It will have a negative impact on the beneficial microorganisms in the system. Consider obtaining a lint filter for your clothes. When we wash our clothing, the lint goes into the system and causes it to get clogged. It is important to remove dirt/mud, as well as other natural sources of soiling (including plant parts) before washing dirty garments. Brush the dirt off before washing soiled clothes.

Never be too busy to spend some time preparing your items for washing, as well as selecting appropriate laundry detergents for the job. Rather than wasting time and money on cleaning or fixing the clogged system later, it is preferable to do it now.

Top Alternative And Natural Cleaning Products For the Septic Tank

Although it is not well known, many commercially available cleaning products are harmful or detrimental to both human health and property. It can refer to both liquid and powdered cleaning products, as well as laundry detergents. Therefore, a large number of homeowners prefer to employ organic and natural ways for maintaining their pipes and septic systems as well! If you are also concerned about the health of your house, look into other methods of upkeep that do not include the use of chemicals.

Its natural nature prevents it from destroying the beneficial bacteria found within the tank, which is in contrast to many chemical agents that do the same.

Primarily employed as a natural cleaning agent A natural liquid cleanser, deodorizer, and grease remover that is quite effective.

Powdered or liquid detergents – septic tank

Having read so much on this site about the advantages of powdered laundry detergent, I was truly startled to find dissenting views on the subject addressed in Heloise’s newspaper column last week. I’m not sure why, but I thought it was interesting. An anonymous reader wrote in to explain that they had an issue with their septic tank and had to have it pumped out, only to discover that there was a pile of powdered laundry detergent in the tank that had not been dissolved at all. Their claims are that the man who cleaned out the septic tank advised them to only use liquid laundry detergent so that the problem would not occur.

I’m sure there are others that feel the same way.

Occasionally, I’ve found that the powdered detergent in the dispenser did not completely dissolve, but instead left a residue.

I also only use powdered detergent in hot water, which is rare for me.

Do you believe this will be adequate to prevent septic tank problems in the future? Is it necessary for me to contact a septic tank provider and inquire about this? I apologize for not having a link to the newspaper piece available.

What Makes A Good Septic Tank Safe Laundry Detergent

When looking for a laundry detergent that is suitable for septic tanks, there are a number of important considerations to take into consideration. In order to determine which laundry detergent will break down better in the tank and thus extend the life of your septic tank, factors such as the type of laundry detergent, whether liquid, powder, or homemade, the level of surfactants, and the presence or absence of biodegradable ingredients will be taken into account.

Powder vs. Liquid vs. DIY

In order to determine which sort of laundry detergent to use, you must first decide between powder and liquid laundry detergent, as well as DIY or homemade laundry detergent. Generally speaking, liquid laundry detergent is considered to be the most effective of these options. Clogging and buildup are two of the most common problems associated with the use of laundry detergent in septic tanks. In contrast to solid laundry detergent, liquid laundry detergent dissolves fully and does not block the septic tank.

Another thing to think about is whether or not you want to produce your own homemade laundry detergent.

This is due to the fact that DIY ingredients in laundry detergents frequently avoid filler elements, and components such as baking soda do not produce excessive suds.

Surfactant Levels

Surfactants are compounds that are found in almost all laundry detergents and other household products. When these chemicals are used to your clothing, they operate to lift and remove dirt from the fabric. Although surfactants may be quite beneficial for cleaning stains off clothing, excessive amounts of surfactants can be harmful to your septic tank’s ability to function. Because septic tanks contain high amounts of surfactants, you will want to choose a laundry detergent that has lower surfactant levels.

Natural surfactants are included in certain laundry detergents, and they can be a better choice since they allow your laundry detergent to remove dirt while also breaking down more quickly in your septic tank.

Natural surfactants are usually derived from plant oils, such as coconut oil in coco betaine and sodium lauryl sulfate, which are both derived from sodium lauryl sulfate. However, they will still suds up but are less likely to biodegrade in a septic tank; as an added plus, they are natural!

Biodegradable Detergents

Because of the nature of a septic tank, decomposition occurs with all of the liquid and solid waste that is transported to the septic tank. Septic systems benefit greatly from the use of biodegradable chemicals. Not only do biodegradable detergents break down more effectively and efficiently, but they also contribute to the growth of beneficial bacteria and natural microorganisms in the septic tank’s interior. Finding detergents that include a higher percentage of biodegradable components will, in the end, be far more helpful to your septic tank over time.

Furthermore, unlike other elements in laundry detergent, these substances will not pose any risks to groundwater or surface water when used in combination.

4 Ways to Protect Your Septic Tank While Doing Your Laundry

If you live in a property that is serviced by a septic tank system, you may have heard horror stories of catastrophic floods brought on by washing machines. Fortunately, most contemporary septic systems are well capable of managing wastewater from your washing machine. However, reckless usage of your washing machine can still cause major problems in your septic tank and lines. Washing machines may cause major damage to septic systems, thus it is best to err on the side of caution to avoid this.

  1. 1.
  2. It is dependent on colonies of helpful bacteria to keep septic tanks running smoothly.
  3. Phosphates and surfactants are common ingredients in laundry detergents.
  4. Detergents are diluted in laundry water so that they do not kill bacteria under normal conditions, but using too much detergent can expose bacteria to toxic amounts of these chemicals, which can be harmful to them.
  5. When you use too much washing powder, the undissolved powder will clump together inside your septic system, causing it to back up.
  6. As long as you use the proper quantity of detergent with each load of laundry, you should not have any of these issues to contend with.
  7. Regularly clean the lint filters.

clumps of lint can escape from the filter and block the septic system if they get stuck in the septic pipes.

If this happens, the septic system can become severely clogged.

Organic fibers in the lint, such as threads from polyester or nylon clothes, will be digested by the bacteria in the tank, while non-organic fibers will be left to settle at the bottom of the tank.


Washing machines consume a lot of water, and washing several loads of laundry in a short period of time might cause your septic tank system to overflow.

Consequently, drainfield obstruction and pollution can occur, resulting in major issues that are typically expensive to treat.

With a tank that is large enough to accommodate many average-sized loads in a day, you should have no trouble washing numerous loads each day.


Another option is to get a modern washing machine, which will prevent your tank from being overloaded with laundry water.

Although they are more expensive, a recent washing machine will allow you to do laundry more frequently without having to worry about septic system difficulties.

Please call the septic system professionals atPete’s Outflow Technicians for professional guidance and recommendations if you have any more concerns about how to safeguard your septic system.

How Laundry Impacts Your Septic Tank

A wide range of alternatives are available when it comes to selecting laundry detergent. Many individuals pick a detergent only on the basis of its aroma, while others have certain requirements that must be satisfied before it can be used in their household.

  • They are also particularly harmful for youngsters since they may easily pop out of the hands of small children who grip them too hard.

Running a Washing Machine with a Septic System

Some people feel that using a washing machine when you have a septic system is a bad idea; however, this is not the case in most cases. There is absolutely no reason to wash anything by hand! Running a washing machine does not pose a threat to the septic tank in and of itself. As opposed to this, it is the sheer volume of water that is being pumped into the system that has the potential to cause problems. Instead of eliminating the use of a washing machine, you should strive to keep track of how much water you are using.

Liquid vs. Powder Laundry Detergent for Septic Tanks
