Septic Tank Installation

A septic tank is a crucial component of a property's wastewater management system - particularly in areas not connected to municipal sewage systems. It serves as an underground chamber for treating and disposing of household sewage and allows for a smooth-running drainage system. If you're a homeowner, it's important for you to know how a septic tank works to ensure proper maintenance and avoid potential issues. 

By gaining insight into its functioning, you can make informed decisions about its care, contributing to the longevity and efficiency of their wastewater management system. In this blog, we will take a look at what a septic tank, how it works - and why they're a good choice for your homes drainage system.

What is a septic tank?

A septic tank is an essential for a home's domestic wastewater management. It functions as an underground compartment that receives and partially treats sewage from households, allowing for the natural decomposition of organic matter and settling solid waste. A septic tank is vital for treating and purifying wastewater, ultimately facilitating its safe disposal into the surrounding environment. 

What does a septic tank do?

A septic tank is a crucial component of household wastewater management. It is a buried, watertight container designed to receive and treat raw domestic sanitary wastewater. Typically made of concrete, fibreglass, or polyethene, the tank holds the wastewater, allowing natural decomposition processes to occur. 

As the wastewater enters the tank, solid matter and sediment settle at the bottom, while bacterial action helps break down organic matter, partially treating the wastewater. The clarified effluent then exits the tank and is treated as it travels through the drain field before being safely disposed of.

So, how does a septic tank work?

A septic tank receives sewage from residential or commercial sources through underground pipes. The tank is designed to separate the wastewater into layers, allowing for the settling of solids and the natural decomposition of organic matter. Let's take a look at the components and what a septic tank consists of.

Components of a Septic System

Septic Tank

A septic tank typically appears as a large underground concrete or plastic container used for storing and treating household wastewater. The tank is an integral part of the septic system, serving as the primary treatment chamber for waste.

Pipes

Pipes connect the septic tank to the house and the drain field. These pipes transport wastewater from the home to the septic tank and then distribute the treated effluent to the drain field. Proper installation and maintenance of these drainage pipes are essential to ensure the efficient functioning of the entire system.

Drain Field

The drain field, or the leach field, is a network of perforated pipes in underground trenches filled with gravel. Its purpose is to disperse the liquid wastewater from the septic tank into the soil. The soil acts as a natural filter, removing harmful bacteria, viruses, and nutrients from the effluent before it enters the groundwater.

Functioning of a Septic Tank

A septic tank serves as a crucial septic system component, functioning to separate and treat household wastewater. The tank operates through a series of processes that involve the separation of solids, effluent, and scum within its structure. Let's take a look at this.

Solids: 

As sewage enters the septic tank, the larger solids sink to the bottom due to the reduced flow rate. This layer consists of the heavy organic and inorganic materials present in the wastewater, such as food particles, soil, and other debris.

Effluent: 

The middle layer is primarily composed of the liquid portion of the wastewater, known as effluent. It fills most of the tank and contains the dissolved and suspended organic matter that has undergone partial decomposition.

Scum: 

The top layer, known as scum, comprises lighter substances like grease, oils, and other floating materials. These substances form a coating on the surface of the effluent, preventing them from escaping the tank.

Process of Waste Separation and Settling

A septic tank's functioning involves the natural waste separation and settling process. Heavy solids settle at the bottom of the tank, where they undergo anaerobic decomposition by bacteria, reducing their volume and transforming them into a more transparent liquid. Meanwhile, the scum layer prevents the escape of lighter materials, allowing the effluent to undergo further treatment before it exits the tank for dispersion into the drain field.

Bacterial Action

Bacteria play a crucial role in breaking down solid waste within septic tanks, contributing significantly to wastewater treatment. The breakdown process, facilitated by bacteria, is essential for the efficient functioning of septic systems.

In the septic tank's anaerobic environment, various types of bacteria work to decompose solid organic waste, including food particles and human waste. These microorganisms, primarily anaerobic bacteria, initiate the breakdown of organic matter, reducing its volume and transforming it into simpler compounds. This breakdown reduces the accumulation of solid waste within the tank and facilitates the conversion of organic matter into a clearer liquid effluent.

Bacteria decompose organic matter, a fundamental aspect of the wastewater treatment process. As bacteria break down solid waste, they help in the natural treatment and purification of the wastewater within the septic tank. This process ultimately contributes to safely disposing of treated effluent into the drain field, where further natural filtration occurs as the effluent percolates through the soil.

Septic Tank Regulations

As with any sewage treatment plant system, regulations and maintenance rules must be considered. In the UK, septic tank regulations are governed by the General Binding Rules, which impose specific conditions for using and maintaining a reliable septic tank and sewage treatment system. 

As of 2015, the new septic tank regulations mandate that septic tanks have a drainage field to ensure proper wastewater treatment. Additionally, septic tanks can no longer discharge untreated sewage into watercourses, and if the discharge causes pollution, homeowners must take corrective measures.

Tips for Maintaining Healthy Septic Tanks and Systems

Maintaining a healthy septic system is crucial for its longevity and efficient operation. Several vital practices contribute to the proper care and maintenance of a septic system:

Regular Pumping: 

Schedule regular septic tank emptying to remove accumulated solids and prevent them from clogging the system. The pumping frequency depends on household size, water usage, and tank capacity.

Water Conservation: 

Practice water conservation to reduce the volume of water entering the septic system. Repair any leaks in faucets or toilets, and consider installing low-flow fixtures to minimise water usage.

Proper Waste Disposal: 

Avoid flushing inappropriate substances down the drain, such as grease, oil, non-biodegradable items, chemicals, and excessive household cleaners. These substances can disrupt the natural processes within the septic tank.

Maintain Drain Field: 

Protect the drain field by avoiding activities that could compact the soil, such as parking vehicles or heavy machinery over the area. Planting trees and shrubs near the drain field should also be avoided to prevent root intrusion.

Periodic Inspections: 

Arrange for periodic inspections by professional septic system service providers. These inspections can reveal issues early on, allowing for timely repairs and maintenance to prevent major problems.

Importance of Periodic Inspections by Professionals

Professional inspections play a critical role in ensuring the optimal functioning of a septic system. Here's why they are essential:

1. Early Problem Detection: Professional inspections can identify potential issues before they escalate into costly and disruptive problems. Early detection allows for proactive maintenance and repairs.
2. System Optimisation: Inspections help optimise the septic system's performance by identifying areas that may require adjustment or improvement. This can contribute to the system's overall efficiency.
3. Compliance with Regulations: Regular inspections are a legal requirement for homeowners with septic systems in many areas. Compliance with these regulations is essential to avoid penalties and ensure environmental safety.
4. Expert Advice: Professional inspectors can provide valuable advice on best practices for maintaining the septic system, including tailored recommendations based on the system's specific characteristics.

Final Thoughts

A septic tank functions as a crucial component of household wastewater management by harnessing bacteria's natural decomposition abilities to break down solid waste. This breakdown process is essential for treating and purifying wastewater, ultimately facilitating the safe disposal of treated effluent into the drain field.

Proper maintenance and care

It is important that you prioritise the proper maintenance and care of your septic systems. Regular pumping, water conservation, and responsible waste disposal are essential practices that contribute to the optimal functioning of the system. Additionally, periodic inspections by professionals play a vital role in early problem detection, system optimisation, compliance with regulations, and expert advice - allowing you to look after your home efficiently.

By understanding how a septic tank works and embracing best practices for maintenance and care, you can ensure their septic systems' longevity, efficiency, and environmental safety. This proactive approach safeguards the household infrastructure and fosters a deeper understanding of this essential aspect of wastewater management.

If you've stumbled across this blog, it's probably because you find yourself thinking about the underground heroes that are septic tanks. Whether you have one in your home or not, a crucial question to consider when looking at these systems relies on the lifespan of these remarkable tools. So, how long do these tanks really stick around for? 

In this blog, we're going to dive into the world of these sewage treatment plants, unraveling the secrets behind their longevity and find out how long of a shelf life they really have. We'll chat about what impacts how long they last and share some practical tips to keep them going strong. 

Brief Overview of Septic Tank Systems

A septic tank is an essential component of wastewater treatment systems for properties not connected to public sewer systems. It serves as an underground chamber typically made of concrete, fibreglass, or plastic. Its job is to treat wastewater, including solid waste sewage from the household, to ensure that your drainage system flows properly.  

The septic tank functions by separating solids and scum and treating wastewater from your home, allowing the liquids to pass through for further processing via an inlet pipe. Ultimately, the tank facilitates the breakdown of waste through biological decomposition processes, ensuring that only treated effluent exits the system for safe disposal.

So, how long do septic tanks last?

In short, the answer is: it depends on different factors. On average, a properly maintained, reliable septic tank can last 20 to 30 years and some well-designed concrete septic systems even have the potential to last between 40 to 100 years. 

However, the longevity of a septic tank is influenced by many factors - some out of the septic tank's control. Let's look at some of these influences to understand better how a septic tank operates and how they can be hindered. 

Factors Influencing Lifespan

The lifespan of a Septic Tank consists of several crucial factors. Let's take a look at the main factors below so that you have a good idea of how they operate best.

Quality of Installation:

Proper installation procedures are essential for ensuring a septic tank's durability and optimal functionality. Attention to detail during the installation, from the initial site preparation to the final inspection, is critical. For maximum life-span, let's take a look at how the septic tank installation process should go.

1. Site Assessment: Before installation, a thorough site assessment should be conducted to determine the best location for the septic tank. Factors such as soil composition, water table levels, and proximity to structures must be considered to avoid future complications.
2. Proper Sizing: The septic tank should be properly sized according to your needs and the needs of the household or property it serves. Undersized tanks can lead to frequent backups and overflows, while oversized tanks may not function efficiently.
3. Precise Placement: The tank should be placed at the correct depth and orientation to ensure proper wastewater flow. Additionally, the inlet and outlet pipes must be installed at the appropriate angles to facilitate waste movement through the system.
4. Secure Connections: All connections, including pipes, fittings, and seals, should be securely installed to prevent leaks and potential contamination of the surrounding environment.
5. Ventilation: Adequate ventilation is crucial for the septic tank to function effectively. Proper vent installation allows for the release of gases produced during the decomposition process, maintaining a balanced ecosystem within the tank.
6. Backfilling: Backfilling around the tank is necessary to prevent shifting or damage. The soil should be compacted in layers to provide stability and support for the tank structure.
7. Inspection and Testing: Once the installation is complete, thorough inspection and testing should be carried out to ensure that all components are functioning correctly. This includes checking for leaks, conducting a hydraulic load test, and verifying proper drainage.

Tank Material

The material of the tank is a crucial factor in determining its longevity and overall performance. When comparing concrete and plastic tanks, each material offers distinct advantages and vulnerabilities that should be considered before making a choice.

1. Concrete Tanks:

• Durability: Concrete tanks are known for their durability and longevity. When well-designed and properly maintained, concrete tanks can last 40 to 100 years, making them a reliable long-term storage solution.
• Strength: Concrete tanks are sturdy and robust, able to withstand external pressure and heavy loads. They provide excellent structural integrity and can serve as their retaining walls in specific applications.
• Maintenance: While concrete tanks have a longer lifespan, they may require periodic maintenance to prevent cracks, leaks, and corrosion.

1. Plastic Tanks:

• Cost-Effective: Plastic tanks are generally more affordable than concrete tanks, making them a popular choice for budget-conscious consumers. They also require less labour and less time for installation.
• Portability: Plastic tanks are lightweight compared to concrete tanks, making them easier to transport and manoeuvre during installation. This portability can be advantageous in situations where flexibility is needed.
• Chemical Resistance: Plastic tanks are inert and non-reactive to most chemicals, ensuring the stored water remains uncontaminated and safe for various uses.

When deciding between concrete and plastic tanks, factors such as durability, cost, maintenance requirements, and intended use should all be considered to select the most suitable option for your specific needs. Proper installation and regular maintenance are key to maximizing the lifespan and efficiency of any water storage tank.

Soil Conditions:

The soil composition and acidity levels in which a septic tank is installed play a crucial role in the overall performance and longevity of the system. Understanding how soil conditions can affect the tank's structural integrity is essential for ensuring the proper functioning of the entire septic system.

1. Soil Composition:

• Impact on Structural Integrity: The composition of the soil, including factors such as texture, density, and permeability, can significantly impact the structural integrity of the septic tank. Too loose or compacted soil may exert excessive pressure on the tank walls, leading to potential cracks or leaks.
• Drainage Capability: Proper soil composition is vital for adequate drainage around the septic tank and drain field. Well-draining soils facilitate the movement of wastewater away from the tank, preventing saturation and potential system failure.

1. Acidity Levels:

• Corrosion Risk: Acidic soils can risk the materials used in septic tanks. The acid in the soil can accelerate the breakdown of tank components, such as concrete or metal, leading to corrosion and structural damage over time.
• Microbial Activity: Soil acidity levels can also impact the activity of beneficial microorganisms within the septic system. Extreme pH levels can disrupt the microbial balance, affecting the decomposition of waste and overall system efficiency.

1. Soil Testing and Assessment:

• Importance of Evaluation: Before installing a septic tank, conducting a soil analysis is crucial to assess the suitability of the soil for wastewater treatment. Factors such as nutrient content, pH levels, and drainage capabilities should be evaluated to ensure optimal system performance.
• Mitigation Strategies: Based on the soil testing results, mitigation strategies can be implemented to address any issues related to soil composition or acidity. This may include soil amendment, installation modifications, or selecting appropriate tank materials that are resistant to corrosion.

By considering the impact of soil conditions on septic tank performance and taking proactive measures to address potential challenges, you can enhance the longevity and efficiency of your septic systems. Regular monitoring of soil conditions and maintenance of the tank environment can prevent costly repairs and ensure the system's smooth operation over time.

Maintenance Practices:

Maintaining a consistent schedule of proper care and attention is essential for extending the lifespan and preserving the efficiency of a septic tank system. By implementing regular maintenance practices, you can mitigate potential issues, prevent costly repairs, and promote the optimal functioning of your septic system.

1. Scheduled Inspections:

• Routine Check-ups: Regular cleaning and inspections by qualified professionals are vital to assess the septic tank's condition and identify any early signs of damage or malfunction. These inspections can uncover leaks, blockages, or excessive sludge accumulation before they escalate into more significant problems.
• Frequency: Inspections should be conducted at least once a year to ensure that the tank operates as intended and promptly address any minor concerns.

1. Timely Emptying:

• Preventative Maintenance: Pumping out the septic tank at recommended intervals is crucial for preventing backups, overflows, and system failures. Regular pumping removes accumulated solids and prevents them from clogging the drain field or causing damage to the tank.
• Pumping Frequency: The pumping frequency depends on various factors, including household size, water usage, and tank capacity. On average, septic tanks should be pumped every 3 to 5 years to maintain optimal functionality.

1. Efficient Water Usage:

• Conservation Practices: Responsible water usage habits, such as fixing leaks promptly, using water-saving fixtures, and spreading out laundry loads, can help reduce the strain on the septic system. Conserving water minimizes the volume of wastewater entering the tank, prolonging its lifespan.

1. Proper Disposal Practices:

• Avoiding Harmful Substances: Refrain from disposing of non-biodegradable items, chemicals, grease, or excessive amounts of household cleaners down the drain. These substances can disrupt the microbial balance in the tank, leading to system imbalances and reduced efficiency.

1. Landscaping Considerations:

• Root Intrusion Prevention: Plant trees and shrubs safely from the septic tank and drain field to prevent root intrusion. Invasive roots can cause damage to the tank structure and compromise its integrity over time.

What to Look out For

Like anything, there is potential for septic tanks to fail - and there are some important signs you can look out for to ensure the correct response. Fixing any septic tank issues as soon as signs arise will ensure that small problems do not become bigger ones. Keeping on top of your sewage tanks will help with the longevity of your septic tank and keep any hazards to a minimum. Let's take a look at important problems to look out for.

• Odours and Sewage Backups: Foul smells around the septic tank area or along drains can indicate issues with the system. Additionally, sewage backing up into the house clearly shows a failing septic system.
• Green Patches in the Drain Field: If you notice unusually green patches of grass near the drain field, it could signal problems with the septic system. This may be due to excess moisture or leakage from the system affecting plant growth.
• Slow Draining Fixtures: Fixtures such as sinks, showers, and toilets draining slowly can indicate septic system issues. This may suggest a blockage or a full tank that needs attention to prevent further problems.

Final Thoughts

So, how long does a septic tank last? If it's installed well and maintained carefully, the average system can typically last you 20-30 years - but not everything is perfect. Understanding the importance of regular inspections, timely pumping, and proper waste disposal habits is crucial for your septic tanks success.

A septic tank is designed to collect sewage and wastewater from households that are not connected to the mains sewer. It’s an efficient way to deal with the waste from your household but does require some maintenance.  Septic tanks do need to be emptied at regular intervals, but how often can vary depending on your model. We recommend having your septic tank emptied regularly, but knowing the tell-tale signs of when your septic tank needs emptying might save you in the long run.

1. Overflowing

As the septic tank gets full, the most obvious sign that this has happened will be overflowing. You might notice pools of water surrounding where your septic tank is located. This could indicate that solid waste has blocked up the system, which means the water is pushed up to the surface. Also lookout for a healthy lawn, noticeable healthier than the rest of your garden. This could indicate there is a leak and it’s time to get your septic tank looked at.

2. A bad smell

When we’re talking about household waste and septic tanks, the smell is never a pleasant one. If you notice a bad smell that can’t be accounted for close to where your septic tank is, then it’s time for someone to come out and have a look.

3. Slow Drains

You might notice your drains stop working as well as they used to. This one is much harder to diagnose, as they could be a multitude of reasons as to why your drains are not draining as they used to. If you notice this across your home and after trying traditional drain remedies; then it might be time to empty that all-important septic tank.

4. Pipe gurgling sounds

Again, with slow drains, if you hear that dreaded gurgling sound coming from your drains. This doesn’t mean that your septic tanks need emptying, but it may indicate something is wrong. Especially if you can hear it from multiple drains. Then is it probably time to get them checked out.

It's important to empty your septic tank at regular intervals and have any required maintenance carried out. This can help fix any small problems before they become bigger problems with a big bill.

The world of drainage regulations in the UK is a complex one, and drainage systems must meet and be maintained to a shopping list of standards, all aimed at keeping the public and the environment safe from the hazards of foul water and flooding.

In this guide, we’re going to run over the importance of these drainage regulations, the key drainage building regulations, navigating local and national guidelines, the importance of professional assistance and certification, the consequences of non-compliance, and why you should stay up to date on the latest standards.

Importance of Drainage Building Regulations

Drainage regulations are in place to control the release and management of foul water. Foul water is defined as water that runs away from or out of plumbing systems such as sinks, toilets, washing machines and dishwashers, or pretty much anything that releases wastewater.

This water needs to be drained away from buildings for the sake of public and environmental health, but also because improper drainage can lead to water accumulating in and around buildings, where it can damage them, causing rot, subsidence and mould.

Drainage regulations exist to ensure that wastewater is handled safely and responsibly, and not left to cause a hazard.

Key Regulations for Residential Drainage

There is a primary set of drainage building regulations that must be adhered to, so it’s worth taking the time to understand them a little better. These are the Building Regulations (2010), or more specifically, Section H of these regulations.

The current iteration of these guidelines came into effect in 2015, and closely governs foul water drainage, wastewater treatment systems and cesspools, rainwater drainage, building over sewers, separate systems of drainage, and solid waste storage.

They include detailed stipulations such as where a septic tank can be placed, how rainwater is drained from roofs and surrounding areas, as well as what standards any drainage equipment needs to be built to.

Compliance with these drainage regulations is crucial, as non-compliance not only risks environmental and health hazards, but also leaves you exposed to prosecution, fines, and costs associated with undoing any non-compliant work.

Navigating Local and National Guidelines

As we’ve mentioned, and as you’ve probably found yourself by this point, the world of rainwater drainage regulations in the UK, and indeed other forms of foul water drainage guidelines, is a complex one.

As a result, in most cases we’d recommend hiring a professional to undertake any work. Registered tradespeople who understand specific drainage regulations will be able to provide work that is compliant with the necessary standards, and even formally certify it – which leads us neatly onto our next point.

Professional Assistance and Certification

Your drainage systems should be regularly inspected for any faults and blockages, as spotting these early will help you handle them before they become larger, more costly issues. To a certain extent, this is something you can keep an eye on yourself, as many drainage issues won’t be able to hide themselves from you for too long.

However, having a professional carry out regular, preventative maintenance is the ideal solution. They will be able to conduct thorough investigations of your drainage systems and address any problems at the earliest possible opportunity. Any costs involved in hiring professionals will be dwarfed by the bill you’ll be footed with should a problem go unnoticed and spiral.

Certified professionals can also register with the government. Once registered, they can provide services to a legally-recognised standard, as well as certify the work that they carry out. From a business perspective, these certifications act as proof that work was carried out to the required standard according to drainage regulations and at the intervals that it should be.

From a domestic standing, you can hold onto the certifications and pass them on to the next buyer when you come to sell your home, as they can help increase its value, much like the service record on a car.

Consequences of Non-Compliance

Primarily, the ramifications for non-compliance with drainage regulations are legal in nature, and can include prosecution, fines, and orders to remove any non-compliant structures.

Additionally, wastewater that isn’t correctly drained can lead to health and environmental risks. It can become stagnant as well as cause mould and decay, which all pose risks to public health. If left for long enough, standing wastewater can even degrade the foundations of a building or the earth around them and lead to issues with subsidence and even collapse.

Staying Updated on Evolving Standards

Building and drainage regulations in the UK are strict, and always evolving. However, it’s your responsibility to know the law, so getting to know drainage building regulations and staying up to date is critical.

The best way to stay up to date is by paying close attention to any updates from the government, as well as engaging the services of trusted, accredited professionals, whose job it is to operate only according to the very latest guidelines and legislation.

Speak to the Experts

Because the world of drainage regulations is so complex and pitfalls are all too easy to find, the best course of action is to work with a registered professional who can help you navigate the requirements with ease.

Septic tanks essentially provide private drainage for sites and buildings not connected to a mains sewerage system. Contrary to popular belief, they’re not just for temporary construction sites or homes in extremely remote areas. Rather, they can be found in up to 500,000 properties across the UK, with many homeowners unaware that they even have one.

In January 2022, the UK government issued a new set of regulations on septic tanks, bringing the issue to the fore. It is now mandatory to either fully replace septic tanks that discharge into surface waterways or to redirect your wastewater to a designated, compliant drain field. With this in mind, you may be wondering “how does a septic tank work?” and “what can I do to maintain my septic tank?”. This blog should answer your questions and quell any pressing concerns, explaining how a septic tank works and delving into septic tank maintenance.

What Is a Septic Tank?

Consisting of a large concrete, plastic or fibreglass container that is typically buried underground, septic tankscollect all the wastewater that runs out of your bathroom, kitchen and other drains via the connected pipework. Nevertheless, they do much more than collect waste. In fact, they are designed specifically to treat your wastewater in situ. This helps to keep the area around your home or business clean and hygienic, in addition to protecting nearby waterways from pollution.

How Does a Septic Tank Work?

Septic tanks are sedimentary systems. This means that, over time, the solids contained in your wastewater settle to the bottom of your tank as sludge, before the remaining liquid (the effluent) is discharged into your drainfield. If your wastewater contains any fats, oils and greases (FOG), they will float to the top of your tank, where they will settle as scum. The bacteria in your tank should naturally break down any solid waste, although the middle wastewater layer may still contain smaller waste particles.

Both the inlet and outlet pipes are shaped like a T, in order to prevent both the sludge at the bottom of your tank and the scum at the top of your tank from seeping into the outgoing pre-processed water. Once this water has left your tank, it will be dispersed evenly to filter through the surrounding soil. The soil will then naturally remove any harmful bacteria, viruses and nutrients from the effluent as it trickles and percolates through the ground, into underground watercourses.

Of course, the sludge that accumulates at the bottom of your septic tank over time will need to be periodically removed, which brings us nicely onto the topic of septic tank maintenance.

Septic Tank Maintenance: How to Maintain Your Septic Tanks

It is your responsibility as the homeowner to adequately maintain your septic tanks, ensuring that they do not impact the local environment. If too much liquid accumulates in your drainfield, this can result in flooding and could even cause sewage to come up to the surface, producing hazardous waste and potentially blocking your sinks and toilets.
If you have already noticed such a blockage or any suspicious smells, it’s best to get things checked out straight away. Nevertheless, there are several essential septic tank maintenance steps you can follow outside emergency situations to keep your system running in top condition as well.

Inspect Your Septic Tank Frequently

Considering how a septic tank works, inspections are recommended at least once every three years. You should always get your systems checked by licensed professionals, who will be able to tell if it needs to be pumped. Pumping tends to be necessary once every three to five years, although the exact timeline will depend on both the capacity of your tank and the total amount of wastewater generated.

In addition to the above, it’s a good idea to check your pumps, float switches and other mechanical components on a more regular basis – usually once a year.

Reduce Water Consumption

The more wastewater your household produces, the more quickly sludge will accumulate in your septic tank system. As such, if you’re looking for simple tips on septic tank maintenance, it may be a good idea to try to reduce the amount of water you use and dispose of. This becomes increasingly important when you consider that pouring too much water into a limited-capacity system all at once could lead to the sludge at the bottom of your tank being stirred up, into the effluent and out into the surrounding environment.

Try to limit the number of times you flush the toilet and be mindful of the water you use. Opt for a shower over a bath and always use plugs in your sinks and basins. Your household appliances, such as dishwashers and washing machines, may also have an eco-mode.

Dispose of Waste Properly

Never flush anything you shouldn’t into your septic tank. The bacteria in there can only digest organic waste, so nappies, sanitary towels and face wipes are all a resounding “no”! They will simply block your drains and ruin your system.

Likewise, although your septic tank is designed to handle a small amount of fats, oils and grease, which will naturally rise to the surface, too much build-up could lead to serious problems, so avoid pouring any of these products down your drains.

It’s not just the typical culprits you need to be aware of, either. As explained earlier in the “How does a septic tank work?” section, septic tanks use bacteria to operate. As such, you’ll want to avoid the use of any harsh chemicals that could destabilise the delicate bacterial balance in your tank wherever possible. Look for bleach alternatives wherever you can but don’t be afraid to use hydrogen peroxide if you really need to. It’s always possible to top up the bacteria in your tank.

Maintain Your Drainfield

The drainfield – the area into which your effluent water finally flows – is often an overlooked aspect of septic tank maintenance. Nevertheless, keeping it in top condition is of utmost importance. Avoid parking or planting trees on top of the area and ensure that other drainage systems, such as your gutters and rainwater pipes, run into another area to prevent a sudden build-up of excess water.

If you live in a rural area or a location without access to a centralized sewage system in the UK, you may need to install your own wastewater treatment system. Septic tanks and sewage treatment plants are two common options for treating household wastewater, but choosing the right size can be a daunting task. In this blog, we will demystify the process of selecting the appropriate size for your UK home, so you can make an informed decision.

Understanding Septic Tanks and Sewage Treatment Plants

A septic tank is a simple, underground tank that collects wastewater from your home's plumbing system. It relies on natural processes to separate solid waste from liquid waste. The solids settle at the bottom of the tank and are broken down by bacteria, while the liquid waste (also known as effluent) flows out of the tank into a drain field where it is absorbed into the ground.

On the other hand, a sewage treatment plant is a more advanced system that uses mechanical and biological processes to treat wastewater. It typically includes multiple chambers or compartments where different treatment processes take place, such as sedimentation, aeration, and disinfection. The treated effluent can then be discharged into the environment or reused for irrigation, depending on local regulations.

Factors to Consider When Determining the Size

When choosing the right size for your septic tank or sewage treatment plant, several factors need to be taken into consideration:

1. Household Size: The number of people living in your home is a crucial factor in determining the size of your system. More residents mean more water usage and wastewater production. As a general rule of thumb, a smaller home with 1-2 bedrooms typically requires a septic tank with a capacity of 2,700-3,400 litres, while a larger home with 3-4 bedrooms may need a tank with a capacity of 3,800-5,700 litres or more.
2. Water Usage: Your household's water usage habits, such as the number of bathrooms, showers, laundry loads, and dishwashing frequency, can impact the size of your system. Higher water usage requires a larger system to accommodate the increased volume of wastewater.
3. Soil Type: The type of soil in your area plays a crucial role in the effectiveness of your system. Different soils have varying rates of percolation or drainage, which can affect the size and design of your system. Clayey soils, for example, may require a larger drain field area compared to sandy soils.
4. Local Regulations: It's important to comply with local regulations and guidelines when sizing your septic tank or sewage treatment plant. Local authorities may have specific requirements on the minimum size of the system based on your location, soil type, and water table level, among other factors. Consulting with a qualified engineer or septic system professional can help ensure compliance with local regulations.
5. Future Needs: Consider your future needs when choosing the size of your system. If you plan to expand your home or increase your water usage in the future, it's best to choose a larger system to accommodate potential growth.

Conclusion

Selecting the right size for your septic tank or sewage treatment plant is crucial to ensure effective and efficient treatment of household wastewater in the UK. Factors such as household size, water usage, soil type, local regulations, and future needs should all be taken into consideration. It's recommended to seek guidance from a qualified professional to determine the appropriate size for your specific situation. Proper sizing and installation of your wastewater treatment system will ensure its long-term functionality and environmental sustainability.

Managing wastewater is an essential part of maintaining any property, especially in rural areas where homes may not be connected to the main sewer system. Many properties in rural locations rely on septic tanks to handle their waste. But how exactly do septic tanks work, and why are they crucial in these areas?

In this guide, we’ll explain the workings of a septic system, why it’s needed in rural areas, and how to keep it functioning at its best. Whether you’re new to septic systems or just looking for more insight, this blog will help you understand why proper septic tank maintenance is key to the health of your home and the environment.

What is a Septic Tank and Why is it Important?

A septic tank is an underground system designed to treat and manage wastewater from properties that aren’t connected to municipal sewer lines. This system is commonly found in rural areas, where properties are often situated far from main sewer connections.

Septic tanks play an important role in safeguarding both hygiene and the environment. They separate solid waste from liquids, allowing the wastewater to undergo natural treatment processes before being safely released back into the ground. Without a well-maintained septic tank, untreated wastewater can contaminate the surrounding soil and water, leading to serious health and environmental risks.

The Three Stages of Septic Tank Operation

Understanding how a septic tank works helps you maintain the system and avoid costly repairs. There are three main stages involved in its operation:

1. Separation of Waste: When wastewater enters the septic tank, solid waste (sludge) settles at the bottom, while oils and grease (scum) float to the top. The liquid in the middle is the wastewater that gets treated.
2. Natural Breakdown: Bacteria in the tank break down the organic matter in the sludge and scum layers. This process reduces the volume of waste and minimizes odors, helping to keep the tank running smoothly.
3. Effluent Discharge: After the wastewater has been treated, the effluent (treated liquid) flows out of the tank into a drainage field or soakaway. There, it filters into the soil, ensuring no harmful contaminants are released into the environment.

Why Rural Areas Need Septic Tanks

In many rural areas, properties are located too far from municipal sewage systems to be connected to public sewers. As a result, homeowners rely on septic tanks to manage wastewater and keep their properties functioning.

A septic tank allows rural homes to handle their waste without the need for a public sewage system. However, maintaining a septic tank in these locations is especially important. Without proper care, issues such as blockages or backups can arise, leading to costly repairs.

Moreover, poorly maintained septic tanks can cause wastewater contamination, which can harm local water sources and the rural environment.

How to Maintain a Rural Septic Tank?

To keep your septic system in top shape, regular maintenance is essential. Here are some tips to help your system run efficiently:

• Regular Pumping: Septic tanks need to be pumped every 3–5 years to prevent blockages and overflows. Regular pumping extends the life of your system and helps avoid costly repairs.
• Mind What You Flush: Avoid flushing non-biodegradable items such as wet wipes, oils, and chemicals. These can disrupt the bacteria in your tank, leading to clogs and potential system failure.
• Routine Inspections: Have your septic tank professionally inspected regularly. Catching problems early can save you money on repairs and prevent larger issues.
• Protect the Drainage Field: Don’t park vehicles or plant trees near your drainage field, as this can damage pipes and block the flow of wastewater.

Septic Tanks are prone to a gradual build-up of deposits and a slowing down of the natural digesting action of the micro-organisms which normally break them down. Leading to malfunctioning of the septic tank causing, blockages, bad smells, overflowing and consequent boggy conditions in the overflow area around the septic tank.

 Can a septic tank cause the toilet not to flush? 

A common sign of septic tank problemsis a toilet that's slow to flush, overflowing or just won't flush at all, and a plunger can't fix the issue. The tank may be full or there could be a blockage in the pipes, so make sure you get this looked at sooner rather than later to avoid major issues and more costs.

How often should I empty my septic tank? 

Every septic tank varies and depends on the size and condition of the tank, some septic tanks require emptyingevery three to five years, some once every 12 months and some more or less frequently. It all depends on the size, the use and the condition of your tank. However, don't make the mistake of waiting until yours is full before doing so because the more sludge there is in your tank, the less efficiently it will work and the more chance there is of it becoming blocked.

Should my septic tank smell? 

A correctly maintained septic tank should never smell! If you notice a horrible drain smell in your house or out near the drainage field, this is a sign that there is a problem with the system, and you should have it checked out by a professional.

Are you following the new guidelines?

In 2020, The General Binding Rules changed to state that discharges from septic tanks directly to watercourses are prohibited. Therefore, you may need to update and upgrade the treatment system to comply with current rules.

Cost of Septic Tank Installation

Septic tank installation costs vary from job to job. We know this can cause some uncertainty for property owners and investors when trying to budget finances. To help alleviate some of those uncertainties here are some factors that affect the overall cost of your septic installation.

Size and Type of Septic Tank

Both the size and type of septic tank system to be installed will affect the price. Larger tanks and advanced treatment systems carry higher price tags. Whilst you should always opt for the correct sized tank to suit your household needs, this is an important factor to bear in mind.

Soil Conditions

The condition and quality of the surrounding soil can also significantly impact septic tank installation costs. Soils that absorb more water, such as clay or silt, can prove to be troublesome and may require additional groundwork to make the area more suitable, increasing overall expenses.

Location and Permits

The location of your septic tank system and its proximity to larger bodies of water matter for permit requirements. In regulated areas or those near wetlands, special construction permits and independent inspections are often required to ensure compliance, whilst preventing the contamination of sensitive ecosystems. Homeowners and property owners should research the necessary permits and inspections required before planning the installation of their septic tank.

Septic Tank Installation Process

Installing a septic tank can be a complex process, one that is best left to the professionals. For more guidance, we have summarised this process, step-by-step to help ensure everything runs smoothly from start to finish.

Step 1: Site Evaluation

A site evaluation helps assess the suitability of your intended location, which usually includes a percolation test that calculates the soil's absorption rate. Once the soil suitability is confirmed, it’s time to determine the ideal location based on your specifications, tank size, piping layout and other varying factors.

Step 2: Permits and Regulations

After the initial site evaluation, the next step would be to research the relevant permits and inspections for your septic system installation. The permit application and approval process can be between 1-2 weeks, and it is important to wait for this approval before starting any groundwork.

Step 3: Excavation and Tank Placement

After marking out the approved area and placement of your septic tank installation, it’s time to dig trenches for the tank itself, piping, electrical wiring and drainage. Follow the relevant guidelines for depth before lowering your tank and the other components into place. Remember to divert the drainage and runoff away from the system.

Step 4: Connecting the System

Now it’s time to connect your household plumbing system to your septic tank. Be sure to test the watertightness of your septic tank outlets to the distribution box and leach drains.

Step 5: Inspection and Testing

The final stage is to inspect your septic tank, testing it out for proper functionality. Also, inspect the surrounding areas for leaks and test out the connected pumps and controls.

Tips for Cost-Efficient Installation

Although installing a septic tank can be a significant investment, by adopting some of the tips and practices below, you can reduce some of the associated costs.

Choose the Right Tank Size

Work with professionals and septic tank experts to choose the right-sized tank for your household and the level of waste produced. Take into consideration the number of occupants and the average amount of water usage. Oversizing your septic tank can lead to higher upfront costs and may cause further issues down the line, whereas under sizing will result in your tank filling up quicker, increasing the frequency of pump-outs.

Soil Improvement Techniques

As a homeowner, ensuring the smooth operation of your drainage system is crucial for maintaining a clean and safe environment. As you explore drainage solutions, you've likely encountered the term 'septic tank' a cornerstone of effective sewage treatment. But do you truly grasp its significance and inner workings?

Understanding the function and maintenance of septic tanks is vital for ensuring the proper disposal of wastewater and preventing environmental contamination. In this blog, we'll delve into the inner workings of septic tanks, explore their ecological and health implications, and provide essential tips for homeowners to maintain their septic systems effectively.

Whether you're considering a property with a septic tank or have an existing system, this knowledge is indispensable for responsible homeownership. Let's uncover the mysteries behind these underground waste management systems and learn how to care for them effectively.

What is a septic tank?

A septic tank is an underground chamber made of concrete, fibreglass, or plastic through which domestic wastewater (sewage) flows for essential sewage treatment. It is a primary component of on-site sewage management systems and is utilised principally for single residences not connected to municipal sewerage systems.

Different types of septic tanks are available depending on property size, soil conditions, installation costs, and specific regulatory requirements. Shallow dig septic tanks are offered to smaller spaces, whereas a traditional septic tank is offered to larger spaces.

Understanding Septic Tanks

The function of a reliable septic tank is to serve three primary purposes. These are the removal of solids, reduction of the flow rate to allow larger solids to sink, and treatment of wastewater through biological decomposition and drainage.

How do they work?

A drainage septic tank receives wastewater from various sources, such as toilets and drains. Once inside the tank, the liquid waste, known as effluent, fills most of the tank while sludge settles at the bottom. 

These sewage tanks act as bioreactors that break down waste into water, with whatever it can't break down sinking to the bottom as sludge or rising to the top as scum. The tank provides a conducive environment for bacteria to break down most solid waste into effluent, which is then piped to the drain field for further treatment.

The Process

A Septic tank consists of a decomposition process. This is where the decomposition of organic matter and the separation of floatable matter and solids from the wastewater occur. Bacteria and other natural processes aid in partially decomposing solids and liquids in the tank. These bacteria, particularly anaerobic ones, thrive in the tank environment and play a crucial role in breaking down waste. Here's a breakdown of how the process of septic tanks works:

1. Separation of Waste: When waste solids enter the tank, they sink to the bottom, decomposing into liquids. Meanwhile, the liquids rise to the top of the tank.
2. Three Layers: Septic tanks allow waste to separate into three layers: solids, effluent, and scum. The solids settle at the bottom, the effluent exits the tank to the drain field, and the scum floats at the top.
3. Effluent Discharge: The liquid wastewater (effluent) exits the tank and is discharged through pipes onto porous surfaces in the drain field. The soil then filters, treats, and disperses the wastewater, ultimately discharging it to groundwater.
4. Natural Filtration: As the wastewater percolates through the soil, it removes harmful coliform bacteria, viruses, and nutrients.

The Benefits of a Septic Tank

1. Cost Savings: Owning a house with a septic tank can lead to savings by not paying for public sewer services.
2. Environmental Friendliness: Septic tanks are environmentally friendly as they do not contaminate the water supply and remove bacteria before releasing water into the soil.
3. Natural Filtering Process: Septic tanks eliminate waste using the natural filtering process of the soil, promoting efficient wastewater treatment.
4. Economic Benefits: Decentralised wastewater systems, such as septic tanks, help communities reduce extensive infrastructure and energy costs for wastewater collection and treatment.
5. Environmental Protection Agency: Septic tanks benefit the environment as they do not contaminate water supplies and promote the removal of impurities.

How Septic Tank Installation Works 

When installing a new septic tank, several critical factors should be considered to ensure proper functionality and compliance:

1. Soil Type and Percolation: The soil type and percolation rate should be assessed to determine the site's suitability for proper wastewater treatment and drainage.
2. Tank Size and Material: Selecting the appropriate tank size and material based on household size, water usage, and environmental conditions is crucial for efficient operation.
3. Location and Drain Field Design: The tank's location and the drain field's design should comply with local regulations and ensure proper drainage and environmental protection.
4. Environmental Impact: Consideration of the potential environmental impact on surrounding water sources and ecosystems is essential.

Regulations and Permits Required for Installation

Local regulations typically do not require a permit for home owners to acquire for septic tank installation. However, you're expected to stick and adhere to local government recommendations.

How a septic tank functions

• Wastewater Collection: Household wastewater from sinks, toilets, showers, and laundry drains into the septic tank.

• Separation Process: Inside the tank, solid waste settles to the bottom as sludge, while lighter materials like grease and oils float to the top as scum.

• Biological Breakdown: Bacteria and enzymes naturally present in the tank help break down organic matter, converting it into liquid effluent.

• Effluent Discharge: The clarified liquid effluent exits the septic tank and flows into the drain field for further filtration and absorption into the soil.

Role of Septic Tanks in Wastewater Treatment

Septic tanks play a crucial role in treating and disposing of household wastewater efficiently and sustainably. Their functions include:

• Primary Treatment: The septic tank acts as the initial treatment stage, separating solids from liquids to prevent clogging and contamination.

• Nutrient Removal: Through natural biological processes, septic tanks remove harmful pathogens and nutrients from wastewater before it enters the environment.

• Groundwater Protection: Properly functioning septic tanks protect groundwater quality by treating sewage onsite and minimising the risk of contamination.

Components of a Typical Septic System

A standard septic system consists of several key components working together to treat and dispose of household wastewater effectively:

• Septic Tank: The primary treatment unit that collects, separates, and partially treats wastewater.

• Distribution Box: Distributes effluent evenly to the drain field pipes.

• Drain Field: A network of perforated pipes buried in soil to further treat and disperse effluent.

• Soil Absorption Area: Soil beneath the drain field where effluent is absorbed and treated by natural processes.

Understanding the fundamental components and functions of a septic system is essential to grasp the importance of proper maintenance and care to ensure the system operates efficiently and protects both property and the environment.
