Septic drain field – Wikipedia
, also known as a land drain.
- A Soakaway is used in a Septic Tank or Sewerage Treatment Plant system when the discharge from your tank is not emitted directly to a watercourse. In a Septic Tank system a Soakaway if correctly installed treats the sewerage. The Septic tank is a separation device holding the most offensive pollutants.
How does a soakaway septic tank work?
A soakaway is a system comprised of a hole dug in the ground and filled with rubble and coarse stones. If a septic tank is being used in an area that doesn’t have the required vegetation to allow the septic tank to dispose of the wastewater in a drain field, a soakaway can assist in removing the waste safely.
What is the difference between a septic tank and a soakaway?
A soakaway is a hole dug in the ground and filled with rubble and coarse stones, designed to disperse water back into the surrounding ground without flooding. A septic tank has two chambers and is buried underground in the same way as a cesspit.
Do you need a soakaway for a septic tank?
A soakaway is not usually needed with a sewage treatment plant, but it is required with a septic tank. Therefore, water from a septic tank will need to undergo further treatment and cleansing in a soakaway or drainage field before it can be safely released into the environment.
How long do septic tank Soakaways last?
If installed correctly a drainage field for effluent should last for around 25 years as a minimum. A rainwater soakaway should last for far longer as long as the gutters are regularly cleaned and filtered.
How long will a soakaway last?
How Long Do Soakaways Last? They should last the life of the house, at least 100 years but only if installed correctly and filters are used to prevent leaves and other material clogging the soakaway.
How far should a soakaway be from a septic tank?
Minimum distances that the drainfield should be from: Buildings – 15 metres. Boundaries – 2 metres. Water abstraction point (well, spring, bore hole) – 50 metres.
How far must a soakaway be from a house?
How Far Should a Soakaway be From the House? You need to ensure its far enough from the structure to prevent damage — 5 metres is the accepted distance, but this also depends on the calculated size of the soakaway.
Can a septic tank drain to a soakaway?
The most significant change to the General Binding Rules, in this case, stated that all septic tanks must not drain to a soakaway but to a drainage field, or drainage fields, definitely not to a local ditch or watercourse. The septic tank itself will only perform about half of the treatment work.
Do soakaways need maintenance?
They catch any mud, silt or dirt particles that are washed into the drain from the gutters, channel drains or land drains that feed into the soakaway. Maintenance is a just a case of removing the lid every three months or so and lifting out and emptying the silt bucket, then replacing it.
Why is my septic tank always full of water?
POOLING WATER It goes without saying, if it hasn’t rained recently and you’re seeing a lot of water, it’s probably your septic tank. This mainly happens when your tank is at full capacity and there could be solid water blocking the system. This will then force liquid up to the top of the ground.
How do you fix a soakaway problem?
How to unblock a soakaway. On most occasions a blockage can be rectified with high pressure water jets, gaining access to the pipework and backwashing it to drag out the silt and leaves, so that it is left clear and running.
How do you check if you have a soakaway?
If you’re wondering ‘how can I tell if I have a soakaway? ‘, simply follow the rainwater pipes down from the side of your house into your garden. If they lead to a slightly lowered area where your lawn dips, there’s a chance you have a soakaway installed.
What is the Difference Between a Septic Tank and a Soakaway?
Consult your local health department or environmental agency if you need extensive septic work done; they could have resources for finding reasonable financing or offering tax credits for the job. By giving low-interest loans to residents, some communities use money collected under the federal Clean Water Act to help them pay septic system upgrades.
What is a septic tank and how does it work?
Septic tanks are used to collect effluent, as well as to store wastewater and solid waste, among other things. A septic tank relies on a pH balance and bacterial activity to break down solid waste, and once the tank is full, it will overflow into a drain field or, more commonly, a soakaway, which is linked to the drain field. Due to the fact that the tank is self-contained and can be installed underground, it is a perfect alternative to traditional sewage lines if your property is not linked to a public sewer system.
What is a soakaway and how does it work?
A soakaway is a drainage system that consists of a pit excavated in the ground and filled with rubble and coarse stones to collect rainwater. This permits surface water that might otherwise begin to pool to be absorbed back into the ground. When a soakaway is constructed, it is usually located away from the flooding region, and a pipe connecting that area to the soakaway is constructed in the form of a gutter or a drain. This method is particularly beneficial in built-up regions that are constructed of impermeable materials because it decreases the amount of pooling water that might cause flooding in the event of a storm.
If a septic tank is being utilized in an area where there isn’t enough vegetation to allow the septic tank to securely dispose of the wastewater in a drain field, a soakaway can aid in safely eliminating the waste.
Which system is best for my property?
Depending on the amount of land on your property, a septic tank with a linked soakaway may be the best option for you if you want to dispose of solid and liquid waste from your house or company in a natural and cost-effective manner. If, on the other hand, you’re wanting to redirect collecting rainfall or surface water off flat or impermeable surfaces, a soakaway is the best option for your situation.

Septic Tank Soakaway Drainfields
A septic tank soakaway drainage field system fulfills two functions:- it serves as a septic tank soakaway drainage field system.
- Additionally, it makes advantage of naturally occurring aerobic soil bacteria to clean up any remaining contaminants in the effluent. It disperses septic effluent into the soil without producing difficulties due to soil saturation and ‘Backing-up’ of the system
- It is environmentally friendly
- And it is cost-effective.
Over 60% of all sites in the UKFAILthe three mandatory tests required to install a septic tank soakaway. If you can’t have a soakaway drainage field, you can’t have aseptic tankand must consider using asewage treatment plantinstead.
The three tests are as follows:
- The location must not be located inside a Groundwater Source Protection Zone as defined by the Environment Agency. This is necessary to protect the drinking water that has been extracted
- The site must pass the deepTrial Site Assessment. There should never be any groundwater (the water table) or rock inside one metre of the soakaway drain pipe. Hole Testand The soil on the site must pass the Percolation Tests and not be excessively sandy or heavy
- The site must be free of debris.
As previously stated, the Environment Agency has verified to us that DEEP BOREHOLE SOAKAWAY drilling since a technique of resolving drainfield concerns is NOT usually acceptable to them, nor are SOAKAWAY TUNNELS, CRATES, AND THE LIKE, as these are designed solely for rainfall soakaways. Keep an eye out for these kind of advertisements on the Internet and report them to Trading Standards!
If you pass the above tests, then the size of the soakaway drainage field will be dependant on the following factors,
1. The soil’s porosity is measured. 2. The size of the property (measured in terms of the number of beds) and the number of people who live in the community it serves. Septic tanks are only permitted for small-scale operations with a workforce of up to around 15 people, according to the Environmental Agency. Drainfield soakaways are made with ditches filled with clean washed stone and fed by solid perforated drainage pipe in a contemporary septic tank system drainfield. There are several ditches that are interconnected and have a grid-like pattern, similar to that of an oven grid tray.
Percolation tests were most likely not performed, which resulted in the results being insufficient and undersized in the first place.
You should empty your tank on a regular basis because if you do not, suspended particles from the tank will be driven down your drains and into your soakaway, blocking the pipes and polluting the soil with a black, slimy biomatt, rendering your drainfield ineffective.
When your tank fills to a level that exceeds the level of the exit pipe, especially after a strong rainstorm, this is a sure indicator that something is going wrong.
Rules and Regulations for Septic and Foul Drainage Soakaway Drainfields
The drainfield should be located at a minimum of the following distances:
- Buildings have a height restriction of 15 metres. Boundaries are 2 metres in length. Distance between the water abstraction point (well, spring, bore hole) and the house is 50 metres. A watercourse (ditch, stream, or river) is defined as a distance of 10 metres. There should be no access roads, driveways, walks, buildings, or other structures inside the drainfield area. If the drainfield is in a field, tractors are not permitted to drive across it. Neither water nor electric cables nor pipes should be located within the drainfield area. The bedrock or water table should never be more than 1.2 metres away from the drainfield pipes at any point in time.

Septic Tank Problems
If you are purchasing a home that includes a septic tank and a soakaway, there are a variety of issues that might occur after the sale. Because it is common for a soakaway to be the source of the problem (either because it was improperly constructed or because it was blocked), it is advisable to have one installed before to purchasing a home. First and foremost, a septic tank soakaway is NOT a “hole filled with stones or boxes” as some people believe. These soakaways are just for ROOF WATER and are not permitted to be used for sewage discharge.
See our Soakaway Drainfieldpage for more information.
Allseptic tanksand theirsoakawayshave problems sooner or later.
It is common for these issues to arise during periods of heavy rain, with the septic tank overflowing, septic tank effluent emerging at ground level, leaking into ditches, or backing up the pipes being the result. These are some of the most frequent septic tank issues. The soakaway drainfield, rather than the septic tank itself, is responsible for the majority of septic tank issues and failures, which can occur with both brick and fibreglass tanks. When it comes to a septic tank soakaway drainfield, there is just one thing you can count on: it will fail!
Boreholes and soakaways are not permitted under the General Binding Rules of the Environmental Agency.
AVOID clicking on advertisements on the internet.
The replacement of all septic tanks whose effluent gets into ditches or streams, either intentionally or by accident, with sewage treatment plants must be completed by the first of January 2020, or BEFORE this date if the land is sold, whichever comes first.
Signs of a failed septic tank soakaway problem:
- Septic tank effluent surfacing on your property (as shown in the photo)
- Noxious or offensive odors emanating from the septic tank or drains
- Effluent pollution of neighboring ditches or streams (see LEGISLATION)
- Toilets flushing at a slow pace
- Gurgling sounds coming from the drains
- A septic tank or soakaway drainfield that has experienced ground movement (dips)
- Overflowing toilet
- Overflowing washing machine hookup
- Overflowing dishwasher
- When the sink empties, the water overflows into the shower or bath. Standing effluent can be seen in the drain inspection chambers of some homes. These should be completely devoid of content. Alternatively, you can look at our other photos of sewerage disasters on sewage reportsor visit the following websites:
The reasons for septic tank and soakaway drainfield failure
Surge of septic tank effluent on your property (as shown in the photograph); the presence of strong or unpleasant odors emanating from the septic tank or drains Contamination of neighboring ditches or streams with sewage (see LEGAL REGULATION); Toilets that flush slowly; In the drains, there is gurgling noise. A septic tank or soakaway drainfield that has experienced ground movement (dips). There is a backup in the toilet; there is a backup at the washing machine hookup. When the sink empties, the water overflows into the shower or bathtub.
These should be completely devoid of any content! We invite you to check our more photographs of SEWAGE DISASTERS on sewage reports or to visit these sites:
2.Depth of the septic tank soakaway drainfield
All septic tank soakaways must be built in the AEROBIC soil layer in order to be effective. This type of soil has oxygen in the air gaps between the particles and can only be found in the top metre of the soil. This is due to the fact that a foul water soakaway performs two functions: the first is to soak up the liquid, and the second is to cleanse the effluent and digest it through the employment of aerobic (oxygen breathing) soil bacteria. Aerobic bacteria have no detrimental effect on soil porosity.
gravel bed beneath the pipe, it is in the ANAEROBIC soil layer, which means that the bacterial growth is anaerobic.
The absurdity of the situation is that most modern ‘onion’ shaped septic tanks come with outlet levels that are deeper than one metre as standard!
As stated in Section H of the Building Regulations 1.39, “Drainage fields should be built and constructed to provide continual aerobic contact between the liquid effluent and the subsoil,” and as stated in BS6297 2008, “The maximum depth of the soakaway pipe should not exceed 700mm.” For what reason do prominent manufacturers create septic tanks that do not meet regulatory requirements?
It is much worse when ‘Cowboy’ installers are hired to complete the job.
3. Nature of the soil and its effect on the soakaway performance
Normal soakaway drainfields will not be able to soak wastewater away into clay or clay-based soils because of their porous nature. Because of the poor porosity, soakaways frequently fail within the first 5 years of operation because the air gaps in the soakaways become clogged with the high amounts of suspended particles in the effluent, which are frequently greater than 1200mg/litre. In addition, this quantity of suspended particles may be found in poorly maintained sewage treatment facilities, and the same principle applies – you can contaminate your own soakaway!) In any case, even with a sandy soil, the high level of suspended particles and the black slime that forms during the decomposition eventually damage the porosity, although it may take 15 to 25 years in some cases.
Solids are ‘blasted’ into the soil’s air spaces, causing the soil porosity to decrease even more quickly and hastening the demise of your soakaway drainfield!
Additionally, after a soakaway failure has occurred, adding commercially available “friendly bacteria” sachets is a waste of time. Because there is no flow into the soakaway as a result, they are unable to do anything to restore the soil’s permeability.
4.Winter water table and its effect on the septic tank soakaway
It is possible that the winter water table will rise to levels higher than the septic tank’s outlet level, resulting in water from the soakaway being discharged back into the septic tank through the outflow line to the soakaway. One thing is certain: water will ALWAYS find its own level, no matter how deep it goes. Due to the fact that the septic tank fills with cleared effluent and settlement chambers mingle with it, when the water level lowers, the resultant effluent is full of particles, which subsequently clogs the soil porosity in the soakaway, this is the most common scenario.
Before purchasing a construction plot, always dig a Trial Site Assessment Hole to assess the level of the winter water table under the ground.
5.Deterioration of the septic tank
Because raw sewage is a very corrosive environment, many septic tanks’ internal divisions/fins/rods, and notably metal struts and bolts (in the case of certain ‘Onion’ septic tanks) and mortar joints (in the case of brick constructed septic tanks), among other components, degrade with time. The hydrogen sulfide gas produced by the decomposing sewage corrodes concrete tanks and causes them to fail. This results in the formation of sulfuric acid on the tank’s lids and walls, which disintegrates the concrete.
Make a mental note of how the concrete is disintegrating.
As soon as the septic tank is no longer capable of clarifying the sewage as a result of internal collapse, the quantity of suspended particles in the final effluent grows quickly, and soakaway failure happens in a very short period of time.
6.Sodium Binding in the soil
Sodium Binding is caused by an excess of sodium (salt) in soils containing fine particles of silt or clay. A waterproof layer is formed around the soakaway trench as a result of the clay particles adhering together as a result of this process. Sodium may be found in a variety of products, including washing powder, detergents, perspiration, dishwashing tablets, water softeners, and the water used in vegetable preparation.
7. Another house joining the septic tank system
Drainage systems such as septic tanks and soakaways are intended to handle a specific volume of liquid each day. You will be unable to raise this amount without also expanding the capacity of the septic tank and soakaway to accommodate the increased volume.
8.Heavy Rain and its effect on the septic tank system
Drainage systems such as septic tanks and soakaways are designed to handle a specific volume of wastewater each day. In order to raise this capacity, the septic tank and soakaway must be expanded to accommodate the increase in size.
9. More people using the septic tank system
If you have purchased a house where only one or two people were previously using the system and you now have a family of four, the amount of water entering the soakaway will have increased significantly. Although the previous owners may not have experienced any issues, this does not guarantee that you will not as well, as the soakaway may not be able to handle the increased daily flow.
The fact that a septic tank treatment system is installed is something to keep in mind when purchasing a home with one.
How to solve the septic tank soakaway failure problem
- If you are not in a Groundwater Source Protection Zone and have adequate area (at least 100m2 of ground that is 15m from any building) and the appropriate soil type, you can completely replace your soakaway drainfield in a different portion of your garden. A winter water table that never reaches within a metre of the bottom of the soakaway, as well as no rock within one metre of the bottom of the soakaway, are also required. All of these are new regulations, and you must follow them to the letter. Unfortunately, over 70% of all sites fail one or more of these standards, and if this is the case, installing additional below-ground soakaways is out of the question. The use of our own copyrightedabove ground soakaways may be a possibility, but new soakaways are not inexpensive to purchase. Please see the link SEPTIC TANK SOAKAWAYS for a more in-depth discussion of these new regulations.
- You have the option of scrapping the entire system and installing a full sewage treatment unit that can discharge to a ditch, stream, land drain, or other location providing it complies with the General Building Rules. The effluent has been removed from your property, as has the hassle of dealing with soakaways. If you have a ditch or other watercourse that is easily accessible, this is now the most affordable alternative available. You can learn more about VORTEX sewage treatment plant by visiting their website. You can purchase a ‘conversion’ kit to install inside your septic tank, but you must be aware that these ‘conversions’ are in violation of the Environment Agency’s General Binding Rules because they do not have and will not be able to obtain the necessary EN 12566 Certification. You will never be able to obtain an exemption from the Environment Agency for these conversion kits, and in any case, they became illegal on July 1, 2013, as a result of the Construction Products Directive. Septic tanks were never intended to be used as a sewage treatment unit in the first place. They have an insufficient number of chambers, as well as the incorrect arrangement of chambers, which are the incorrect size to accommodate the situation. It would be necessary to dig up your septic tank and ship it, along with the conversion kit, to an EN Test Center in Europe for performance testing in order to obtain a Permit for one of these. The testing would cost around £30,000 and you would be issued the necessary EN 12566-3 Certificate
- However, the testing would cost approximately £30,000. You may utilize your septic tank as the first settlement stage of a comprehensive three-stage sewage treatment facility. Installation of theSeptic Tank Conversionunit follows the installation of the septic tank and is linked to the output line. This unit will convert your system into a full sewage treatment unit
The FilterPod sewage treatment plant is the only plant in the United Kingdom that has received the necessary EN12566-6 Certification, and it is the only septic tank conversion unit that has been approved by the Environment Agency under the General Binding Rules. Be wary of certain providers and INSIST on seeing their EN12566-6 Certificate – they will not have one if you ask for one. The final effluent from an aerated septic tank conversion unit meets the same standards as the final effluent from a full-scale sewage treatment system.
Despite the fact that it has a larger capacity than a ‘all in one’ sewage treatment equipment, the septic tank may still survive for up to 12 months between emptyings.
- Even if you have recently purchased a home that has an inoperable septic tank system, it is sometimes feasible to utilize the legal process to force the seller’s Solicitor to pay for the necessary repairs or replacement. It is also feasible to have your Buildings Insurance provider reimburse you for the whole cost of the new system. For further information, please see our sewage systems insurance website or call James Webb on 01759 369915.

Septic tank and soakaways failures
Fabian Belin published an article on March 30, 2015.
How to avoid septic tank and soakaways failures?
The majority of septic tanks and soak-aways have issues, which mainly involve drain pipes backing up or the septic tank overflowing, resulting in effluent backing up and seeping into ditches, damaging the surrounding environment. When it comes to septic tank difficulties, it is more often than not related to the soak-away system rather than the septic tank itself. Failure of soak-aways can be caused by a wide range of variables, including improper maintenance of the septic tank, soil type and composition (soil quality), elevation of the groundwater table, and the design specifications of the septic system.
Whether you see any of these indicators, you should lift the drain inspection chambers to see if there is any standing effluent in them and clean them.
- The most common causes of septic tank and sewage system failure are as follows:
Reason 1: Poor septic Tank Maintenance
The majority of septic tanks are sadly not properly maintained since their owners are sometimes under the mistaken impression that they are saving money. For example, onion-shaped fiberglass septic tanks produce less high-quality effluent than classic brick concrete two-chamber septic tanks, which are more expensive. Septic tanks have a storage capacity of 12 months’ worth of sludge, and as a result, they must be emptied at least once every 12 months.
If sludge is washed into the soakaway system, it has a significant impact on the soil’s ability to retain water. Thus, the effluent will not have the opportunity to soak up into the groundwater.
Reason 2: Wrong soakaway Depth after the septic system
In accordance with Section H of the Building Regulations 1.39, ‘Drainage fields shall be built and constructed in such a way that aerobic contact between the liquid effluent and the subsoil is achieved.’ In reality, most modern septic tanks in the shape of an onion have outlet levels set more than a meter below ground level, which results in the use of anaerobic conditions after the septic system, which is undesirable.
- Soakaways for septic tanks should be built on soil that has plenty of oxygen.
- The ground serves as a medium for dispersing the effluent and is also employed as a component of the system to break up and digest the effluent that will eventually be treated.
- Because of this, it is recommended that the soakaway depth not be larger than one meter below ground level, including the 300mm gravel bed that is often present under the pipe, in order to prevent the soakaway from attempting to work in anaerobic conditions.
- This bacterium is not harmful to humans.
Reason 3: Soil Type and/or groundwater table
Drainage fields shall be built and constructed in such a way that aerobic contact between the liquid effluent and the subsoil occurs, according to Section H of the Building Regulations 1.39. In reality, most modern septic tanks in the shape of an onion have outlet levels set more than a meter below ground level, which results in the use of anaerobic conditions after the septic system, which is not desirable. Soakaways for septic tanks should be built on soil that has plenty of organic matter.
The ground serves as a medium for dispersing the effluent and as a component of the system for breaking down and digesting the effluent to be treated.
Rather than breaking down the affluent, a distinct form of bacteria occurs that produces a slime that reduces the amount of time the soakaway can be used before it has to be replaced, ultimately resulting in a loss in soil porosity.
Reason 4: Septic Tank construction and septic system capacity
Soakaways are intended to handle a specific volume of wastewater generated on a daily basis. With an increase in the volume of wastewater generated, it is necessary to rebuild the soakaway so that it can accommodate the increased treatment capacity required. The corrosive atmosphere of a septic tank may cause metal elements to corrode, as well as mortar joints to erode over time. Internal parts of the septic system, such as fins, rods, and metal struts and bolts in the “onion” type septic tanks, as well as the joints in the brick-built septic tanks, are affected by this corrosion.
A result of this corrosive action is the internal collapse of the septic system, which results in a dramatic increase in suspended particles in the final effluent and the failure of the soakaway within a short time period. As a result, the septic tank is unable to effectively clear the sewage.
What is a Soakaway? We explain everything
In order to handle a specified volume of wastewater each day, soakaways are built. Increased wastewater production necessitates the reconfiguration of the soakaway system to accommodate the additional treatment capacity required. The corrosive atmosphere of a septic tank can cause metal elements to corrode, as well as mortar joints to crack and crumble over time. Internal portions of the septic system, such as fins, rods, metal struts and bolts in “onion” style septic tanks, as well as the joints in brick-built septic tanks, are affected by this corrosion.
Consequently, the septic tank is unable to effectively filter the sewage.
Regulations
There are rules and regulations in existence regarding wastewater soakaways, which are primarily intended to safeguard the environment from contamination. You may learn more about septic tank regulations in our Guide to Regulations, but the most important thing to remember is that a septic tank should only discharge to a drainage field unless a permission has been obtained for some other form of soakaway arrangement. A sewage treatment facility may discharge directly into a watercourse or onto a drainage field; however, any other sort of soakaway system would necessitate the obtaining of a permit as well.
Ground conditions
It is possible for ground conditions of a property to vary over time, notably the presence or absence of underground water (also known as the water table). As a result, the drainage field or soakaway’s ability to operate properly may be impaired, resulting in issues.
Usage of the septic tank or sewage treatment plant
When using a septic tank or sewage treatment plant, it is critical to operate the tank as carefully as possible. This will guarantee that you receive the most number of years of service out of your soakaway or drainage field. Take a look at our post on things you should and should not flush down your toilet.
Percolation tests
An apercolation test must be performed on a property prior to the design and installation of any drainage field or soakaway system on the land. In order to determine the appropriateness of the ground conditions and the needed size of any drainage field, it is necessary to conduct a percolation test.
Damage to the tank can cause problems for the soakaway
Wastewater treatment facilities and septic tanks are meant to prevent solid waste from departing a holding tank and making its way into a drainage field or soakaway. The damage to the tank may result in solid waste particles becoming trapped in the soakaway, which will cause the drainage system to overflow. If you have reason to believe that damage to your septic tank has occurred, it is critical that you get it examined as soon as possible.
Septic Tank Versus Soakaway
If you’re constructing a new home and don’t have access to the city’s sewage system, or if you’re searching for a more environmentally responsible approach to recycle your used water, you’ll need to think about how you’re going to deal with any surplus waste generated during the construction process. Both septic tanks and soakaways are excellent wastewater treatment options, and while they serve slightly distinct functions, a combination of the two is frequently the most effective wastewater treatment solution.
When it comes to choosing a septic tank over a soakaway, it’s important to understand the differences between the two systems. This will help you pick the system that will best fit your needs and save you money. So, let us begin with the septic tank:
What is it and how does it work?
Essentially, a septic tank is a self-contained system of tanks that is used to collect effluent as well as solid waste and wastewater for storage purposes. In the first tank, bacterial activity breaks down solid waste, allowing it to be recycled. Afterwards, the partially treated effluent passes into the second chamber, where it is subjected to additional natural biological action. It is then held within the tank until it overflows into either a drainage field or a soakaway, where microorganisms in the soil will further decompose the waste and release it into the environment.
When it is not possible to connect a property to a centralized sewer system, this sort of system is frequently employed in rural locations.
What about a soakaway?
Instead of a tank, a soakaway is just a pit in the ground that has been filled with coarse stones and debris. This is in contrast to the use of an aseptic tank. The mix of stones and debris allows surface water to dissipate into the ground rather than remaining on top of the surface. An underground soakaway may be positioned away from any regions of flooding, but it will be connected to the flooding area by a pipe that serves the same purpose as a gutter or drain between the flooding area and the soakaway.
A soakaway system can be used to regulate waste water on its own, or it can be used in conjunction with a septic tank in situations where there isn’t enough space for a drainage field to be installed.
The difference between a sewage water soakaway and a surface water soakaway
To distinguish it from an aseptic tank, a soakaway is merely a pit in the ground that has been filled with coarse stones and debris, rather than a tank. The combination of stones and rubble allows surface water to dissipate into the ground rather than remaining on top of the ground. An underground soakaway may be positioned away from any regions of flooding, but it will be connected to the flooding area via a pipe that serves the same purpose as a gutter or drain. Because it permits water that would otherwise pool and flood to naturally’soak away,’ soakaways are particularly beneficial in densely populated regions where impermeable materials have been used in construction.
Using a soakaway, the waste may be securely evacuated from the area.
Should you choose a septic tank or a soakaway?
Septic tank installation on your property provides an environmentally friendly and cost-effective method of disposing of solid and liquid waste. Depending on the type of land surrounding your septic tank, you may also be required to connect a sewage soakaway to handle the effluent generated by the tank.
If, on the other hand, you have rainwater or surface water gathering on a flat or impermeable surface on your property, constructing a soakaway will be beneficial to you.
How long does a septic tank soakaway last?
The use of a septic tank is a common method of disposing of waste when you are not linked to a public sewage system. In order to improve the efficiency of this method, a soakaway is frequently constructed to handle the wastewater. A soakaway in conjunction with a septic tank is an effective way to handle waste, but like with any system, it is important to keep it in good working order. In reality, a soakaway has its limitations and may only be utilized under specific circumstances. At OMDI, we have extensive experience in the design and construction of septic tanks, as well as the construction of soakaways to accompany them.
How do septic tanks work?
Septic tanks are often built in the backyard or in a garden, away from a house or structure. It breaks down trash and separates solids from liquids by using bacteria as a catalyst. Using an effective drainage system, the effluent is then gently released into the surrounding ground. A soakaway is incorporated into the design at this point.
What is a soakaway?
In its most basic definition, an asoakaway is a hole in the earth that is filled with rocks. It will be placed distant from the septic tank, and the wastewater will be discharged into it after that. It is expected that the wastewater will disperse through the rocks and slowly seep into the surrounding soil and ground water. For those unfamiliar with the phrase, a soakaway is an underground drainage system that provides for the proper disposal of sewage from an on-site septic tank. Pipes link it to a septic tank, which serves as a holding tank.
The soakaway provides a gradual technique of diffusion, which prevents wastewater from collecting and puddling, as well as helping to avoid floods in the area.
How long does a soakaway last?
Septic tanks require frequent maintenance to ensure that they continue to operate efficiently. In order for the wastewater disposal system, which includes the soakaway, to continue to work, maintenance must be performed on a septic tank to remove the sludge that has built up. Every 12 months, septic tanks must be emptied and maintained to ensure that they are working properly. However, they should also be serviced if they begin to smell, since this may be the first indicator of a serious problem in the future.
If there are difficulties with the septic tank, you will discover them in the drainage field.
In order for a soakaway to function properly, it must be allowed to accumulate sludge and waste products before they obstruct effective drainage of wastewater.
When it comes to drainage systems, OMDI knows exactly how to set them up so that they endure for a long time. We can also assist you with servicing and maintaining a soakaway system in conjunction with a septic tank for the best results.

The soakaway begins to fill up from the first day, and the FOG used in cooking is not broken down by anaerobic bacteria, which is a good thing. Soakaways begin to obstruct from the very first day. After a while, the earth becomes completely sealed, and water can no longer escape. Whenever there is a backup of water in the Septic Tank, to the point where the water level rises past the tee on the output pipe, the FOG, which constitutes the majority of the floating solides, instead of being held, escapes!
The soakaway will be unfit for any use very quickly.
Septic Tank Emptying
Anaerobic bacteria do not break down the FOG used in cooking, therefore the soakaway begins to build up from the first day. Since day one, Soakaways have begun to obstruct. Water can no longer escape as the earth gradually becomes completely sealed. Whenever there is a backup of water in the Septic Tank, to the point where the water level rises past the tee on the exit pipe, the FOG, which is the principal component of the floating solides, instead of being held, escapes! Because of the FOG, the soil becomes suffocating, and the beneficial aerobic bacteria are unable to break down the organic stuff present.
About Septic Tanks
A septic tank is a tank in the ground that partially cleanses raw sewage before the unclean water is sent into a soakaway for disposal. For many years, septic tanks served as the primary method of removing waste from the environment. Despite the fact that the effluent should be directed to a soakaway, it occasionally finds its way into the river system (including ditches). Environmental regulations have changed recently, therefore it is critical to verify that your septic tank is up to date with these changes.
- A T-shaped input pipe directs the flow of untreated sewage downhill.
There is an assumption that the sinking solids will settle at the bottom of the container and the floating solids will float on top. Fats, oils, and greases make up the majority of the floating solids (FOG).
- Sinking solids settle to the bottom of the tank, whereas floating solids float on top of the tank, according to the theory. Fats, oils, and greases are the primary constituents of floating solids (FOG).
If the level of water in the soakaway rises above the top of this T pipe, the floating solids will be able to escape via the pipe.
Desludging
The man who is performing the desludging may accidentally break the Tee on the Outlet pipe, which will result in all of the floating solids, including FOG, flowing out into the soakaway once the Septic Tank is full, which is normally within a few days following the break.
No one notices, but the soakaway is now forced to deal with the most toxic portion of the organic debris. It is necessary to have a Tee on the Inlet pipe that is about 600mm long in order to send all solids down into the area of the tank that is farthest from the Outlet pipe.
Sewage Treatment Plant or Septic Tank?
In the event that your septic tank system fails, what are your alternatives?
- Replace the existing soakaway
- Construct a pump station, which will pump the effluent to a shallower soakaway
- And complete the project. It is possible to convert an existing septic tank into a sewage treatment plant. In lieu of the septic tank, install a sewage treatment plant and a soakaway
- And Install a Sewage Treatment Plant and pump the effluent out to a shallow soakaway
- Install a Sewage Treatment Plant and pump the effluent out to a ditch. Replace it with a Sewage Treatment Plant, and the sewage will just flow into a ditch.
Replace the current soakaway; construct a pump station to pump wastewater to a shallower soakaway; and complete the project. The Septic Tank will be converted to an advanced wastewater treatment facility. Septic tanks should be replaced by a sewage treatment facility and a soakaway. Install a Sewage Treatment Plant and pump the effluent out to a shallow soakaway; install a Sewage Treatment Plant and pump the effluent out to a ditch. Substitute Sewage Treatment Plant for it, and you’ll just end up in a ditch.
- (Population Equivalent) The number of persons that are currently enrolled in the system whether or not you need to use a pump whether or if there is enough room and access available for the installation
- The work should be carried out by British Water engineers who are qualified in their field.

If you plan on discharging into a river, keep in mind that the Environmental Agency requires effluent to have a biological oxygen demand (BOD) of 20 or less (Biological Oxygen Demand). More information about this procedure may be found here. A Septic Tank can only create 200 BOD under ideal conditions, hence in this scenario, we propose putting anAllerton ConSeptinside the Septic Tank to increase the amount of BOD produced.

Unblocking a septic tank soakaway
Everything went successfully with the installation of your wastewater drainage system. You’ve been taking use of the system’s advantages while remaining blissfully oblivious of its inner workings. All of a sudden, difficulties appear.
Liquid patches form near the soakaway system when the septic tank overflows, toilets stop flushing correctly, or septic tanks overflow. Use this tutorial to assess whether or not your soakaway is the source of your difficulties, as well as what you need do to resolve them.
Avoiding blocked soakaways
Because of the complexity and price of rebuilding a septic tank soakaway, it is far more cost effective to prevent blockages than it is to cure them. Fortunately, many of the difficulties associated with clogged soakaways may be avoided if the subterranean drainage system is correctly planned and constructed, since it should have a long life span and not necessitate the need for extensive upkeep. Read our tutorial on how to build a septic drainage field for additional in-depth information on recommended practices.
Causes of septic tank soakaway blockages
However, even with proper installation, it is still possible for a clog to occur in a soakaway system. For example, a septic tank soakaway can become clogged as follows:
- Resulting from dip pipe or baffle problems in the septic tank
- If the septic tank isn’t emptied on a regular basis, it might cause problems. Growing tree roots impede the flow of water through the system, causing pipes to become constrictive, damaged, or even collapse. Individuals who flush non-biodegradable and man-made materials through the system (such as sanitary goods, diapers, cotton buds, and so on)
- When the soakaway was placed, there was a large rise in water use, which exceeded the predicted water capacity.
Signs of a blocked soakaway
There are some signs you can look for to determine whether or not your soakaway is the source of your drainage problems. These are some examples:
- Waterlogging and saturated ground are problems. Sewage or drain odors that are foul in the scent department Slow-flushing toilets and gurgling sounds coming from the drains are common problems. Overflowing water in the bathtub, sink, toilet, and so on)
- The presence of distortions in the ground over the soakaway, such as dipping, might indicate the presence of collapsed piping.
Unblocking your septic tank soakaway
Determine the root cause of your soakaway’s obstruction problems before you can start working on a solution. You should obtain assistance from an expert to evaluate your soakaways and septic tank if you are unclear of the sort of obstruction you are experiencing. They will be able to identify the problem more quickly, and if your soakaway can be unblocked, they will have the skills and tools necessary to complete the job properly. You should also check to see whether any of the problems you have identified are covered by your insurance coverage.
Soft blockage
Additionally, when there is “soft blockage” created by an accumulation of items that have been flushed through the system, it is a good idea to consult with a professional business. This person should be able to offer the required care and attention to resolve the situation without causing more harm. You’ll also want to make sure that everybody who has been using the toilet that has been linked to the system is aware of what they are not permitted to flush away.
Natural blockage
Natural materials such as silt and leaves might be the source of your clog. If this is the case, soakaways may be cleaned in some circumstances. The piping should be accessible through a rodding point, and the undesired material should be removed using a high-pressure jet washer or hose under high-pressure pressure. The use of this procedure, however, does not ensure success in cases when the dirt build-up is very difficult to remove. Septic tank soakaway blockages are sometimes impossible to clear or are just not cost effective, in which case the system will need to be rebuilt.
Replacing a septic soakaway
The installation of a septic tank soakaway should be done in such a way that all obstructions are avoided. Consequently, when a blockage occurs, it is sometimes too severe to be repaired simply, needing the replacement of the whole drainage field.
Tree root damage, collapsed pipes
In order to avoid any and all obstructions, it is important to build a septic tank soakaway correctly.
Consequently, when a blockage occurs, it is sometimes too severe to be repaired simply, needing the replacement of a whole drainage field.
Septic tank issues
In certain cases, damage to the dip pipe or baffle in your septic tank may be the cause of the problem. This is particularly problematic because the aim of these things is to keep solid waste out of the soakaway. As soon as solid waste enters your wastewater drainage system, the surrounding environment becomes very contaminated very quickly as a result. This might result in more issues with septic tank overflow in the future. Unlike other types of soakaway damage, this type is permanent.
Improper installation
A drainage field that has not been established in accordance with the requirements of Part H of the Building Regulations is at danger of being blocked. The placement of the soakaway too close to buildings, sidewalks, or roadways might result in the collapse of the pipes. The absence of a geotextile might result in silt accumulations in the soil. Failure to complete the required tests on the ground might result in floods when the water table becomes overburdened, resulting in property damage. It is possible that any of these issues will need the replacement of the soakaway.
Because of legal guidance, every new soakaway must not only adhere to the placement standards outlined above, but it must also be put in a different area from the original soakaway.
New Septic Tank Regulations 2020 in England, Wales & UK
If you’re building a home, living in a rural area, or owning land that is not connected to the mains drainage system, it’s critical that you be up to date on the latest septic tank regulations. To combat water pollution, the Environment Agency has established General Binding Rules, which means that by January 2022, you will be required to update or replace your septic system, unless you meet certain criteria. Septic tanks have the potential to pollute groundwater resources as well as surface water in lakes, streams, rivers, and other bodies of water.
- Septic tanks were first regulated in 2010, according to the Environmental Protection Agency.
- In 2011, the government amended its strategy, and a consultation was launched in 2014 as a result.
- Septic tank laws 2015 prescribe how septic tanks are to be regulated in England, with the goal of improving water quality and protecting the environment in the process.
- ‘New discharge’ refers to a device that was installed and started discharging after the specified date.
1:Soakaway System
Water from the septic tank is drained through a network of drainage pipes in neighboring sub-soils, where it undergoes another sort of treatment before being discharged back into the environment.
This assisted in ensuring that the wastewater being released did not pollute the environment. Sewage treatment plants that discharge onto a drainage field are not subject to the 2022 septic tank soakaway requirements.
2: Waterway
The sewage is channeled via a conduit and discharged straight into a lake, river, or creek. The new standards do have an impact on direct discharge to a waterway since they simplify the fact that direct septic tank discharge into a ditch will no longer be permitted under the new guidelines. Septic tank owners are required to follow the “general binding requirements,” which include making certain that their system is properly maintained and does not pollute waterways or soil. Additional safeguards are in place in environmentally sensitive areas, where persons may be required to apply for a permission before entering the territory.
New Septic Tank Regulations In 2022 Explained
Let’s get down to business: what exactly is changing with respect to septic tanks as of the first of January 2022? If you’re responsible for a property that has a septic tank, or if you’re considering purchasing a property that has a septic tank, you should be aware of the future legal obligation to upgrade by 2022, which may have an impact on your situation. Please use the following information to determine if you will be obliged to take action toward compliance before 1 January 2022 in order to avoid breaking rules and incurring an unwelcome fine in the amount of $100,000 or more:
Septic Tank Regulations England
A septic tank is a tank that separates particles from wastewater and then releases the liquid septic waste to the earth through a drainage field that has been properly built and constructed. A soakaway crate or soakaway pit is not an Ezy drain, tunnel, or soakaway crate. These substances are not permitted for use in wastewater dispersion. Surface water drains, rivers, canals, ditches, streams, or any other sort of waterway are prohibited from discharging into septic tanks. According to the newEnvironmental Agency Septic Tank General Binding Rules, if you have a specific septic tank that discharges to surface water (river, stream, ditch, etc.), you are required to upgrade or replace your septic tank treatment system to a fullsewage treatment plant by 2022, or when you sell your property if you purchased it prior to this date, whichever comes first.
- Sewage treatment facilities with complete BS EN 12566-3 documentation are replaced, or the discharge to the waterway is obstructed and redirected to a drain field built and constructed in accordance with the most recent British Standard BS6297 2007 is implemented.
Septic Tank Regulations Scotland
If your property is located in Scotland, you are required to register any sewage treatment discharges, both current and new, with SEPA(Scotland) by the first day of January in the following year. As long as the discharge has been in use since the first day of April 2006, you can register it if the discharge is for 15 or less individuals. Otherwise, you cannot register it. If it was in use before to April 1, 2006, you may be able to register it if it is for a group of 50 or fewer persons. In order to operate with a population greater than these during the times specified above, you must get a license from SEPA.
Septic Tank Rules and Septic Tank Registration Wales
It is mandatory to register your septic tank or sewage treatment plant with Natural Resources (Wales) before the year 2022 if your property is located in Wales.
You’ll also need permission from the local government if you discharge water into the earth through a watercourse or drain field. It is normally free for small-scale discharges, subject to the following conditions:
- If your sewage treatment plant or septic tank discharges into a drain field in the ground and your residential property has up to 13 occupants, you may be required to install a septic tank. If your package sewage treatment plant flows into a river and the residential property has less than 33 occupants, you may be eligible for a grant. Assuming there is no protected place nearby, or that the groundwater beneath your property flows to a water extraction point that is utilized for human use, you should take precautions. For example, a source protection zone for drinking water or a place of exceptional scientific interest are both examples of what is meant by “special scientific interest” (SSSI). Natural Resource Wales will investigate this once your application has been received.

Frequently Asked Septic Tank Questions… Answered!
The following are some questions you could ask about your septic system that will help you better understand whether or not your septic tank is ready for 2022, how to maintain it, and how it works:
What are Small Sewage Treatment Plants and Septic Tanks?
In order to better understand if your septic tank is ready for 2022, how to maintain it, and how it performs, here are some questions you might have regarding your septic system.
- Solids are collected at the bottom of the tank, where they are turned into sludge, and liquid is discharged onto a drainage field, where microorganisms cleanse the waste as it seeps into the earth. This substance is not permitted to be discharged into a waterway. In the same manner, a Small Sewage Treatment Plant operates, but it makes use of mechanical parts to oxygenate the microorganisms, which increases their effectiveness at treating effluent and allows them to discharge treated wastewater into flowing water or a drain field. An important distinction is that, instead of being cleaned and released, raw sewage is collected and stored in an underground tank, which implies that the general binding laws do not apply to cesspits or cesspools. Cesspit rules, on the other hand, state that they must be drained when they are full and that they should not be permitted to leak or overflow.
What are My Responsibilities as a Homeowner?
According to the Environment Agency’s new code of practice, homeowners are responsible for the installation and maintenance of the sewage treatment system on their property, as well as for reducing the system’s impact on the surrounding environment.
What are the Deadlines?
It is possible that the Environmental Agency may discover that you are now damaging surface water through the discharge from your septic tank before January 1, 2022, and you will be obliged to construct a new system prior to the new legislation being effective. As a result, you’ll have 365 days to upgrade, albeit the exact length of time will be determined on an individual case-by-case basis.
What are the Options?
There are two methods in which you may ensure that you are in compliance with the new regulations:
- Septic tanks should be replaced by wastewater treatment plants because they generate water that is clean enough to be discharged directly into a river
- . Install a soakaway system or a drain field – this will collect wastewater from your septic tank and safely release it into the earth without polluting the environment
What Do The New Regulations Mean For Septic Tank Owners?
Because of the ‘General Binding Rules,’ every septic tank that was erected and is discharging on or after the 1st January 2015 must comply with the rules by discharging to a drain field. This is referred to as a ‘new discharge,’ and no action is required; however, if your septic system was discharging prior to the regulations taking effect on the 31st December 2014, you have a ‘existing discharge,’ and no action is required. It is no longer judged safe to use ‘existing discharges,’ and the Environment Agency requires that these septic systems be replaced with new, compliant systems by the first of January 2022.
According to the Environmental Agency, if your septic system provides a major risk to the environment or human health, or if it is polluting the environment, you will be required to modify or replace your septic tank by the first of January 2022 and within 365 days after receiving notification.
What Else Do I Need to Know?
Check to be that your septic system is properly sized and installed in accordance with the new septic tank installation rules before using it. Always refer to the Government’s Approved Document Hbefore beginning any installation project or executing any maintenance. As a result, you’ll need to make sure your tank is maintained and emptied on a regular basis by a professional (such as a qualified waste carrier) in accordance with the manufacturer’s recommendations. It is the seller’s responsibility to inform potential buyers in writing if an estate contains a septic tank, as well as the tank’s maintenance requirements and exact location.
Keep in mind that if you live in Scotland, Wales, or in or near groundwater source protection zones (SPZ1), you may be subject to additional regulations. However, you should always double-check with your local environmental agency in addition to consulting your manufacturer.
How to Follow the Regulations and Protect Your Local Environment
Conforming to the general binding norms is a simple process. The following are the most important things you must do:
- Have your septic system emptied by a licensed trash hauler on a regular basis to ensure that it does not pollute the environment. Maintain your septic system on a regular basis, and get any issues or flaws repaired as soon as possible
- A maximum of 2,000 liters of treated waste per day into the ground or 5,000 liters of treated trash per day into flowing water is the limit for each day you discharge treated waste. If you discharge more than a certain amount, you’ll need a permission
- Before building a new septic system, check with the Environmental Agency to see whether you’ll need to obtain a permit from them. Consult with your local government to establish whether or not your system complies with building and planning requirements.
Quick Tips for Maintaining Your Septic Tank
Maintaining your septic system effectively will assist you in reducing your energy usage, avoiding expensive repair fees, and preventing pollution. Here’s how it’s done:
- Ensure that the sludge is dumped on a regular basis by a licensed trash carrier. Get it serviced once a year by a trained engineer, and deal with any issues as soon as they arise. Check your local river or stream on a regular basis for indicators of pollution such as grey fungus, luxuriant weeds, froth, sludge, pools of water, or sewage odors, among other things. If you notice any of the following issues, contact a professional for assistance: Wipes, diapers, sanitary goods, and other similar items should not be flushed down the toilet since they might clog the system. Chemicals, oils, and fats should not be flushed down the toilet because they destroy the microbes that aid in the breakdown of waste. Keep phosphate detergents out of your laundry since they are hazardous to the environment. Maintain records of your system’s upkeep so you’ll know when to empty and service it.
Conclusion
Fortunately, there is still time to make the changeover. It’s not all doom and gloom though. After all, no one likes to think of the residents of the local rivers or streams wallowing in the contaminated water from septic tanks, therefore it’s a good thing that the situation has changed for the better. To find out whether your septic tank has existing or fresh discharge, get in touch with the Environment Agency, who will be able to tell you whether your system is compliant.
