What Element Is Soakaway And Septic Tank In A Construction Bill? (Correct answer)

Do you need a septic tank for a soakaway system?

  • THE SOAKAWAY SYSTEM A soakaway system normally includes screens, a catch pit, a septic tank, soakaway pit and trenches, and the associated dung channels. Farms which can achieve very high levels of dry removal ofsolidwaste,andlowlevelsofwateruse(ie.chickenandsmall duckfarms), willnot normallyrequire septic tanks.

Is a soakaway a watercourse?

To a drainage field or soakaway system – The waste water percolates through holes or slots into the pipe work, into the surrounding soils. To a watercourse – the waste water would flow through pipe work to a watercourse.

Is a soakaway a drainage field?

A drainage field/soakaway is designed to spread partially-treated effluent over a larger area. Drainage fields typically consist of a system of sub-surface irrigation pipes which allow the effluent to percolate into the surrounding soil. Biological treatment takes place naturally in the aerated layers of soil.

What is septic tank and 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. Blockages can cause flooding.

What is septic tank construction?

The septic tank is a buried, water-tight container usually made of concrete, fiberglass, or polyethylene. Its job is to hold the wastewater long enough to allow solids to settle down to the bottom forming sludge, while the oil and grease floats to the top as scum.

Do all septic tanks have a soakaway?

A soakaway is not usually needed with a sewage treatment plant, but it is required with a septic tank. This is because the water released by a septic tank is primary treated effluent, meaning it has only gone through one stage of treatment.

Can you use a soakaway for a septic tank?

Soakaway CRATES and TUNNELS are also not allowed for septic tank or any sewage effluent, only for rainwater.

How does a soakaway septic tank work?

A soakaway in simple terms is a hole in the ground filled with rocks. It will be set away from the septic tank, and wastewater is then released into it. That wastewater will diffuse through the rocks and slowly escape into the surrounding ground.

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 big does a soakaway need to be for a septic tank?

The minimum size a soakaway should be constructed to is 30m. Pipes should be laid on a 300mm layer of shingle or medium of up to 50mm. The trenches must be filled 50mm above perforated pipe and covered with a membrane and then filled in with soil.

What constitutes a soakaway?

Soakaways are a long established way of dealing with rainfall. They are essentially a pit in the ground into which you run your rainwater drainage. They are also used, less frequently, to dispose of the effluent from septic tanks, where they are more commonly known as leaching fields.

What is soakaway in plumbing?

A soakaway is where surface water from your roof or driveway is piped to a large underground pit filled with gravel within the boundary of your property, normally 10 to 15 feet away from the foundations. This allows the water to slowly drain into the ground surrounding the soakaway and re-enter the watercourse.

What material are septic tanks made of?

Tank Materials Concrete, fiberglass, and plastic are commonly used. Concrete is sturdy, and it’s still used for some septic tanks today.

What are the parts of a septic tank?

A typical septic system has four main components: a pipe from the home, a septic tank, a drainfield, and the soil. Microbes in the soil digest or remove most contaminants from wastewater before it even- tually reaches groundwater. Your Septic System is your responsibility! Howdoes it work?

How Your Septic System Works

Underground wastewater treatment facilities, known as septic systems, are often employed in rural regions where there are no centralized sewage lines. They clean wastewater from residential plumbing, such as that produced by bathrooms, kitchen drains, and laundry, by combining natural processes with well-established technology. A conventional septic system is comprised of two components: a septic tank and a drainfield, often known as a soil absorption field. It is the septic tank’s job to decompose organic matter and to remove floatable stuff (such as oils and grease) and solids from wastewater.

Alternate treatment systems rely on pumps or gravity to assist septic tank effluent in trickling through a variety of media such as sand, organic matter (e.g., peat and sawdust), constructed wetlands, or other media to remove or neutralize pollutants such as pathogens that cause disease, nitrogen, phosphorus, and other contaminants.

Specifically, this is how a typical conventional septic system works:

  1. All of the water that leaves your home drains down a single main drainage pipe and into a septic tank. An underground, water-tight container, often composed of concrete, fiberglass, or polyethylene, serves as a septic system’s holding tank. Its function is to retain wastewater for a long enough period of time to allow particles to sink to the bottom and form sludge, while oil and grease float to the surface and produce scum. Sludge and scum are prevented from exiting the tank and moving into the drainfield region by compartments and a T-shaped outlet. After that, the liquid wastewater (effluent) exits the tank and flows into the drainfield. The drainfield is a shallow, covered hole dug in unsaturated soil that serves as a drainage system. Porous surfaces are used to release pretreated wastewater because they allow the wastewater to pass through the soil and into the groundwater. In the process of percolating through the soil, wastewater is accepted, treated, and dispersed by the soil, finally discharging into groundwater. Finally, if the drainfield becomes overburdened with too much liquid, it can flood, causing sewage to flow to the ground surface or resulting in toilet backups and sink backups. Finally, wastewater percolates into the soil, where it is naturally removed of harmful coliform bacteria, viruses, and nutrients. Coliform bacteria are a kind of bacteria that may be found in the intestines of humans and other warm-blooded animals, with humans being the most common host. As a result of human fecal contamination, it is a sign of this.

The Guadalupe-Blanco River Authority has built an animated, interactive model of how a residential septic system works, which you can view here.

Do you have a septic system?

It’s possible that you’re already aware that you have a septic system. If you are not sure, here are some tell-tale symptoms that you most likely are:

  • You make use of well water. In your home, the water pipe that brings water into the house does not have a meter. In the case of a water bill or a property tax bill, you will see “$0.00 Sewer Amount Charged.” It is possible that your neighbors have a septic system

How to find your septic system

You can locate your septic system once you have confirmed that you have one by following these steps:

  • Taking a look at the “as constructed” drawing of your house
  • Making a visual inspection of your yard for lids and manhole covers
  • Getting in touch with a septic system service provider for assistance in locating it

Failure symptoms: Mind the signs!

Examining the “as constructed” drawing of your house; Checking for lids and manhole covers in your yard. A septic system service company who can assist you in locating it is to be sought.

  • Water backing up into the drains of homes and businesses
  • It is especially noticeable in dry weather that the drainfield grass is bright green and spongy. The presence of standing water or muddy soil near your septic system or in your basement
  • A strong stench emanating from the area surrounding the septic tank and drainfield

Quantifying the impact of septic tank systems on eutrophication risk in rural headwaters

Open access is granted under a Creative Commons license.


Septic tank systems (STS) are a possible source of nutrient emissions to surface waterways, however there is currently insufficient data in the United Kingdom to determine their relevance for eutrophication in the country. In this study, we looked at the influence of STS on nutrient concentrations in a stream network surrounding a typical English community over the course of one year. Septic tank effluent discharged through a conduit directly into a single stream included significant concentrations of soluble nitrogen (8–63 mgL 1) and phosphorus (1–14 mgL 1), as well as other nutrients (Na, K, Cl, B, and Mn), which were representative of detergent and household inputs.

  1. Ammonium-N and soluble reactive P (SRP) fractions were also dominant (70–85% of total).
  2. Annual flow-weighted concentrations of NH 4 N and SRP rose from 0.04 and 0.07mgL-1, respectively, upstream to 0.55 and 0.21mgL-1, respectively, downstream at the ditch location, where flow volumes were low.
  3. The highest nutrient concentrations were found at all locations when the flow rate was low, and stream discharge was shown to be the most critical element influencing the eutrophication impact of septic tank systems in all cases.
  4. The findings were published in the journal Environmental Science and Technology.

Research highlights

The first concrete proof in the United Kingdom that nutrient emissions from septic tank systems have an impact on water quality in rural regions Septic tank soakaways on impermeable soils were found to have failed to adequately treat septic tank effluent in some cases. The downstream eutrophication impact of septic tank systems is highly dependent on the volume of wastewater discharged into streams. When it comes to watershed management planning, septic tank systems are considered mini-point sources that need to be more effectively managed.

Septic Tank Costs: How to Save Money in 2022

Despite the fact that many people who live in urban areas take sewage systems for granted, those who live in rural areas understand the critical role that septic tanks play in their lives. Homes in areas where there is no access to mains sewage must have a septic tank installed, which serves as a holding tank for the waste generated by bathtubs, toilets, and dishwashers. According to their size, they should be emptied at least once a year and are a crucial part of any drainage system. As we proceed through this article, we’ll look at how much septic tanks cost, what factors influence the cost of a septic tank, how to save money on septic tanks, how to determine whether or not a septic tank is the best option for your home, as well as how to locate and hire a company to maintain your septic tank for you.

How Much Do Septic Tanks Cost?

The amount you may anticipate to pay for a septic tank will vary based on the size you choose and whether you want an above-ground or below-ground installation. Here are a few of the most prevalent varieties to consider:

Septic Tank Type Estimated Supply Cost Estimated Installation Cost Time Required Total Estimated Cost
Above Ground (up to 2,200L) £1,300 to £1,650 £300 to £800 2 to 4 days £1,600 to £2,450
Above Ground (up to 3,400L) £2,100 to £2,300 £450 to £1,000 3 to 5 days £2,550 to £3,300
Above Ground (up to 4,500L) £2,400 to £2,750 £750 to £1,400 5 to 7 days £3,150 to £4,150

Below Ground (up to 4,800L) £1,200 to £1,860 £2,700 to £3,350 5 to 7 days £3,900 to £5,210

Above Ground

An above-ground septic tank with a capacity of up to 2,200 gallons is expected to cost between £1,300 and £1,650 to install, depending on the manufacturer. You’ll need to set aside two to four days for the installation, as well as between £300 and £800 to pay the price of the installation. Depending on the specifications, an above-ground 2,200-litre tank might cost anywhere between £1680 and £2490 to build in total. A tank up to 3,400 litres in capacity, installed above ground, will cost between £2,100 and £2,300 for the supply expenses alone, with an extra £450 to £1,000 in installation charges, and will take between three to five days to complete the installation.

The final of our above-ground septic tanks is a 4,500-litre capacity tank with a supply cost ranging from £2,400 to £2,750.

It is the most expensive of our above-ground septic tanks. This will take between five and seven days to install and will cost between £750 and £1,400 in addition to the original cost. The overall cost of an above-ground 4,500-litre tank is projected to be between £3,150 and £4,150 on average.

Below Ground

Looking below-ground, a 2,800-litre septic tank will cost between £800 and £1,300 to purchase and install, depending on the supplier’s terms. It will take between two and four days to install, and it will cost between £1,200 and £1,800 to complete the job. The overall cost of a below-ground 2,800-litre tank is expected to be between £2,000 and £3,100 on average. The next item on the list is a below-ground 3,800-litre septic tank, which will cost between £1,000 and £1,500 for the supply only. It will take between three and five days to install and will cost between £2,000 and £2,500 to get it done.

Finally, we’ll take a look at a below-ground 4,800-litre septic tank, which will cost between £1,200 and £1,860 to install and maintain.

The entire cost of a below-ground 4,800-litre tank is projected to be between £3,900 and £5,210, depending on the specifications.

What Affects the Cost of a Septic Tank?

Septic tanks may quickly escalate in price and become quite expensive pieces of equipment. When it comes to arranging your installation, here are some things to keep an eye out for.


In the same way that you might imagine, the size of your tank will have a significant influence on the price. Building requirements in the United Kingdom require you to purchase a tank that holds at least 2,700 litres, or 2.7 cubic metres, of water, which will be adequate for four people. If your family has more people than this, the general rule of thumb is to add 180 litres of water for every new person in your household. It doesn’t matter if you don’t have permanent occupants in your home; if you often have parties and have friends and family stay over, you’ll need to examine if your septic tank is up to the task of handling the extra traffic.

Always keep in mind that septic tanks not only collect used toilet and bathroom water, but also wastewater from washing machines and dishwashers, which must be disposed of properly.

Smaller tanks will require more frequent emptying, increasing maintenance costs; however, larger tanks will not only be more expensive, but they may also limit the number of tanks available for purchase because larger tanks must typically be installed below ground, limiting the number of tanks available for purchase.

Location (Above or Below Ground)

The placement of your septic tank will have an influence on the cost of installation; whether it is above-ground or below-ground, and both tanks are available in a variety of types, the position will be important. Above-ground tanks are often less expensive and are ideal if you simply want a small water storage system. The most cheap options are designed in the shape of low-profile boxes that can be linked together if you want more wastewater storage capacity. Despite the fact that above-ground tanks are less expensive to install, they require regular emptying, which can become expensive over the course of a tank’s lifespan.

However, on tiny sites, you may be forced to purchase a below-ground tank due to a lack of available surface area on the surface.

Before making a decision on what is best for you, you should always check local restrictions before purchasing your tank, since some municipalities restrict the types of septic systems that may be used.


Drainage systems are necessary for below-ground tanks, and the installation of these systems may add to the overall cost of the tank. In addition, the installation of anokaaway, which allows part of the effluent to be filtered out into the surrounding ground, is an advantage of a huge underground storage tank. As a consequence, your tank will need to be filled less frequently, allowing you to save money in the meanwhile. It goes without saying that you must first confirm that the ground is adequate for a soakaway and that it will be able to absorb some of the surplus water before installing a tank.


The type of material used to construct septic tanks has an impact on the price of the tanks. Unsurprisingly, higher-quality materials are more expensive, but if you have the financial means, it’s worth it to spend a little more money up front because the tank will last longer. The following are examples of typical materials you’ll come across:

  • Concrete, plastic, fibreglass (also known as GRP or Glass Reinforced Plastic), and steel are some of the materials used.

Construction materials include concrete, plastic, fibreglass (also known as GRP or Glass Reinforced Plastic), steel, and aluminum alloys.


Construction labor expenses will have a significant influence on septic tank installation prices, which can range from the hundreds of dollars to several thousand dollars for below-ground tanks. If you’re having a tank replaced, you’ll also need to account for the expense of removing the old septic system from the property.

Annual Maintenance Costs

It is labor that has the greatest influence over cost of installation for an above-ground septic tank, which can range from hundreds to several thousand dollars for below-ground systems. If you’re having a tank replaced, you’ll also need to account for the expense of removing the old septic system from your property.

How Can I Save Money on a Septic Tank?

Now that we’ve established how expensive septic tanks may be, let’s look at some of the cost-saving strategies that can help keep some additional expenses at bay.

Dig It Yourself

However, you may save money on the pre-installation phase, which is a welcome relief. If you’re having a below-ground septic tank put, you might want to consider doing some of the ground preparation yourself to save money on labor costs. Excavation is quite straightforward, and the cost of hiring a digger will be significantly less expensive than the cost of engaging a professional crew to build the tank on your property. Furthermore, if you have some basic plumbing knowledge, you could even install the entire drainage system yourself – but if you’re unsure about anything, it’s always more cost-effective in the long run to hire a professional to do it for you in the first place, rather than calling for emergency assistance later on.

Buy The Best Tank Possible

While you may save money by preparing the site yourself, it is worth you to invest in the finest tank available in order to save money in the long run. If you expect your family to grow, purchasing a tank that is just large enough for now may appear to be the most cost-effective option. However, if you need something much larger in a few years, the cost of removal, digging, and re-fitting will outweigh the initial cost. This statement applies to the type of material you choose as well. While concrete is a low-cost alternative, it is not the most long-lasting, and you will find yourself renewing it considerably more frequently than you would have preferred.

It’s worth holding off a little longer to save a little more money in order to acquire something that will fit you for years to come, both in terms of size and material. Getting multiple quotes can save you up to 40% on your insurance: Quotes may be obtained by clicking here.

What Is a Septic Tank?

A septic tank is an underground chamber that is used to treat residential wastewater to a modest degree. It is intended to store wastewater for an extended period of time, allowing particles to settle to the bottom and oil and grease to float to the surface. After that, the liquid waste is filtered away.

How Much Does It Cost to Install a Septic Tank?

In most cases, a new septic tank system will cost you around $3,900 to install. It costs between $1,500 and $5,000 to install a conventional 1,250-gallon tank, which is the perfect size for a three- or four-bedroom house. This price includes the tank itself, which ranges in price from $600 to $2,100 or more depending on the size and kind. Workman’s compensation is included in the price of the installation and often ranges from $1,500 to $4,000.

Types of Septic Tank Systems

Septic tank installation and replacement costs are heavily influenced by the type of system that you select to use. Tanks come in a variety of shapes and sizes. Here are a few examples:

Anaerobic Septic System

Anaerobic systems are a popular alternative for many homes since they don’t require any additional electricity or chemicals to function properly. Anaerobic systems include microorganisms that do not require oxygen to exist and hence are called anaerobic systems.

Solid waste is broken down by microbes, and any leftover liquid waste is pumped out and spread beneath the surface of the soil. The garbage is naturally recycled when the water seeps into the ground and returns to the environment. The installation of these devices is between $2,000 and $5,000.

Aerobic Septic System

Aerobic systems, in contrast to anaerobic systems, make use of microorganisms that do not require oxygen to live. To activate the bacteria in the tank, oxygen is injected into it, and the bacteria then feed on the solid waste. Aerobic systems perform effectively in soils that are unsuitable for other systems and in areas where the groundwater table is elevated. It is an excellent choice for residences that are close to a body of water. Aerobic systems are more costly to install than anaerobic ones.

Gravity Septic System

Gravity septic systems employ gravity to filter and move water through the system. They must be put on a mild slope in order to allow water to flow without the use of a pump. The cost of installation ranges from $1,500 to $4,000.

Conventional Septic System

A standard septic system is comprised of a septic tank and a trench that serves as a drain field for the collection of waste. The trench is built on stone or gravel and is designed to allow water to move through it easily. In order to prevent sand or dirt from contaminating the clean soil, geofabric is laid over the top of the trench and secured in place. In order to function properly, a traditional septic system requires a huge amount of room. The installation of these devices is between $2,000 and $5,000.

Mound Septic System

If your groundwater is close to the surface, a mound septic system is the best alternative. An area for the septic system is prepared, and a sand mound is built to allow effluent from the tank to be pumped into the mound in modest amounts. The sand then acts as a filter, preventing the water from reaching the soil and groundwater. This design necessitates a large amount of floor space. They’re also expensive to install since a sand mound needs to be built before they can be utilized. The total cost is between $10,000 and $20,000 per person.

Chamber Septic System

Chamber septic systems have lately gained popularity as an alternative to traditional septic systems. They are comparable to conventional systems, with the exception that plastic chambers, rather than gravel, are utilized in the drain field. These are less difficult to build and have a lower carbon footprint. The cost of installing them ranges from $1,500 to $5,000.

Septic Tank Materials

Another aspect that influences cost is the type of material used to construct your septic tank. The following are some of the most often seen materials:


Concrete septic tanks are the most prevalent form of septic tank because they are extremely long-lasting and reliable. They can survive for 20 to 30 years if they are properly maintained. Concrete, on the other hand, may break with time. When concrete is reinforced with rebar, the strength of the concrete is increased when subjected to pressure. Because of its weight, installation is more difficult and necessitates the use of specialized equipment. The cost of a typical-sized concrete tank ranges from $720 to $2,050 dollars.


Fiberglass does not deteriorate when utilized underground, and because it is nonporous, it will not support the formation of algae.

Because of the tank’s modest weight, it is easy to install. You won’t have to worry about cracking since, unlike concrete, it will not expand or shrink as the weather changes. The typical cost of a fiberglass tank is between $1,600 and $2,000.


Tanks made of plastic are lightweight and simple to install. They’re also fairly long-lasting. Plastic tanks range in price from $830 to $1,400 on average, depending on the kind.


In spite of steel’s strength and durability, septic tanks built of steel are susceptible to rust and collapse if not properly maintained. As a result, several municipal governments have tightened their restrictions in order to discourage their usage. Typically, you’ll discover them in regions where the system was already in operation. If you are able to have one installed, they range in price from $900 to $9,900.

What Size Septic Tank Do You Need?

The size of your septic tank is normally decided by the number of bedrooms in your house. This is used to calculate the amount of water that will flow through the system on a daily basis. In general, the expense of a system increases in direct proportion to its size.

Two Bedrooms

The size of your septic tank is usually decided by the number of bedrooms in your house. When estimating how much water will flow through the system on a daily basis, this method is employed. In general, the cost of a system increases in direct proportion to the size of the network.

Three Bedrooms

A minimum of a 1,000-gallon water tank is required for a three-bedroom residence, which handles around 360 gallons of water each day on a daily basis.

Four Bedrooms

A bigger tank, with a minimum volume of 1,250 gallons, is required for a four-bedroom residence. It is capable of handling around 480 to 600 gallons of water each day. Additional Related Articles:

Septic Tank Repair Costs

It’s conceivable that only a certain component of your septic tank has to be replaced rather than the complete tank. Repairs and replacement parts can be purchased for a fraction of the cost of a complete system replacement. The following are some of the most often seen repairs:

Drain Field

Drain fields can get overloaded and flood, resulting in sewage backing up into toilets and sinks. The cost of replacing a drain or leach field ranges from $3,500 to $11,000.

Tank Pump

A replacement septic tank pump typically costs between $500 and $1,200.

Tank Filter

Septic tank pumps are typically priced between $500 and $1,200.

Tank Lid

Concrete coverings and steel lids may break and corrode as a result of exposure to the elements. In most cases, you can repair a septic tank lid on your own for about $35 and $60. In most cases, having it changed by a professional is more expensive.

Tank Baffle

The baffle is responsible for directing wastewater through the septic tank. A replacement baffle piece will cost between $23 and $44 dollars.

Additional Factors to Consider

A septic tank can be built either below or above ground, depending on your preferences. Because of the amount of excavating and footing preparation required, installing a tank underground is a pricey endeavor. Underground septic tanks necessitate the construction of a drain field that can accommodate a soakaway. In addition, because the soakaway allows for part of the wastewater to drain into the ground, the tank will require less emptying over time. Over time, this might result in a reduction in your expenditure.

Some demand that an inspector check and approve the site, which might result in a fee being charged to the homeowner. Depending on your state, septic tank licenses may be required to be renewed, but in most cases, you will be required to pay renewal costs when your permission expires.

How Long Does a Septic Tank Last?

The lifespan of a septic tank varies based on the material used and the type of system used. The lifespan of a septic tank might be reduced if the tank becomes clogged due to roots or floods from groundwater. Septic systems have a lifespan of 15 to 20 years on average. Maintaining your septic tank on a regular basis is the most effective approach to extend its life. Keep in mind that maintaining your tank entails more than just draining out the contents; it’s also crucial to have a professional evaluate your tank on a regular basis and perform routine maintenance.
