What is a slurry tank? Everything you need to know

Need somewhere to store your slurry? We’ve got you covered.

Slurry tanks, silos, pits and lagoons – there’s plenty of options (and names) out there, but what do you need? Well, a slurry tank is often a great shout.

Here we’re delving into the realm of slurry tanks, a great option for the modern farmer looking to elevate their game, maximise their capacity and enhance their slurry’s nutrient value.

But what is a slurry tank, and how do they work? Hold tight; we’ve got a lot to get through.

What is a slurry tank? The basics

When it comes to on-farm storage, there’s lots of options to choose from. You may think that as long as you’ve got something in place, you’ll be fine. But do you know your slurry silos from your slurry pits?

If not, head to our 2023 guide to slurry storage, where we take a deep dive into the fundamentals of each.

But for now, we’re answering one main question: what is a slurry tank used for?

Simply put, slurry tanks are versatile containers designed specifically to hold a mixture of organic materials – including manure, water and other agricultural byproducts.

While unpleasant, storing this mixture is like gold dust to a farmer, eventually transforming into a nutrient-rich, highly effective fertiliser to enhance crop yield. You may also hear these referred to as slurry silos, agriculture tanks, or digestate tanks.

Unlike pits and lagoons, which also offer large capacity storage space for your slurry, farm slurry tanks stand out by offering controlled storage conditions, mitigating the risk of leaks and environmental harm.

Slurry tank benefits

Now we know the basics, it’s time to break down the slurry tank benefits:

• Due to hazardous waste being contained and controlled within the sturdy walls, a slurry tank prevents contamination, acting as a more environmentally-friendly option.
• If properly installed, your farm will be compliant with slurry tank regulations – avoiding hefty fines and penalties.
• You’ll maximise your slurry’s nutrient value due to better management, enhancing the yield and quality of your crops. More bang for your buck!
• Better space efficiency due to bespoke, customisable spaces so you can store more slurry and create more fertiliser.
• As a secure reservoir for manure and waste, slurry tanks keep everything under wraps to keep nasty odours at bay

All in all, the key role of a slurry tank is to aid in the conversion of organic matter into valuable fertilisers. These tanks don’t just store, they contribute to the circular economy of farming! However, for more into the benefits of slurry storage here.

Key considerations in slurry tank design

Slurry tank design isn’t just about aesthetics; it’s a science that needs to be mastered.

Capacity

When selecting a slurry tank, farmers must assess their overall waste production to determine the right tank capacity.

An easy way to do this is by using the handy Agriculture and Horticulture Development Board (AHDB) slurry wizard.

Just fill in a few details about your business and farm’s operations, like your herd numbers, acres of land and more. From there, the handy tool will run the maths to work out your requirements and explore which storage scenarios work for you while complying with the regulations from the Department for Environment Food & Rural Affairs (DEFRA).

There’s no one-size-fits-all solution for slurry storage. That’s why we offer a range of solutions, bespoke and customised to what your farm needs.

With a range of tank sizes, paired with durable slurry tank covers, we’re here to ensure waste management meets productivity.

Location, location, location

Placing your slurry tank must be a strategic move rather than a random decision. Placement affects efficiency, safety and ease of maintenance. And not to mention the minefield of regulations that must be adhered to!

In 2024, 2,487 pollution incidents were recorded. And unfortunately, that’s a huge 31% increase on the 2016 levels – meaning it’s more important than ever to take the issue seriously.

As a quick overview, DEFRA outlines a few slurry tank regulations (last updated in 2024), that basically state how slurry stores and water must keep their distance.

Fresh or coastal waters? Keep your tank at least 10 metres away. Springs, wells or boreholes? Maintain a 50 metre buffer.

Plus, there’s a few important documents you need to sift through before getting to work, such as checking your farm records, mapping and flood risks. These all work to ensure risk factors such as pollution from run-off or flooding by understanding your soil type, slopes and presence of land and yard drains. 

Longevity, efficiency and safety

Every year, farms nationwide are producing and utilising millions of tonnes of livestock slurry. So it’s important to store it efficiently to make the most of it!

The design of a slurry tank directly impacts its efficiency and safety. Well-designed tanks promote proper mixing, reducing the likelihood of sediment buildup and aiding in effective waste breakdown.

Slurry tanks can be built from a variety of materials, depending on what you’re after. For instance, our steel mesh slurry tanks are made out of durable materials with a galvanised exterior and interior.

However, the mesh allows these tanks to be adaptable, acting as agile partners that mould themselves to your needs. Easy to install and dismantle, a mesh panel slurry tank offers a solution that harmonises with the uniqueness of your farm.

Alternatively, our steel panel slurry tanks are a more long-term solution, made from corrugated steel panels and a double layer protective system.

Whichever tank you choose – whether it’s an easily-manoeuvrable, quickly-installed mesh slurry tank or the sturdy, permanent steel slurry tank – both will be constructed to ensure longevity, safety and efficacy.

Durable construction and secure covers ensure that both the environment and workers are safeguarded – the top priority on your farm.

Types of slurry tanks and their applications

We’re proud to offer a whole range of slurry tank types to suit your farm’s specific requirements – but what slurry tank design is right for you? Let’s take a look:

Vertical or horizontal slurry tanks?

Vertical slurry tanks:

Vertical tanks are the masters of space optimisation. For farms with limited real estate, these tanks stand tall, efficiently utilising vertical space while minimising their footprint.

Ideal for cramped quarters, vertical tanks bring a sense of height to your farm, maximising storage without sacrificing precious ground.

Horizontal slurry tanks:

Enter the world of horizontal tanks – the champions of simplicity and convenience.

These tanks lay low, effortlessly fitting into your daily operations. Their design ensures easy access and maintenance, simplifying your interactions and minimising downtime.

Steel mesh or steel panel slurry tanks?

Farmers’ guide to slurry tank maintenance

Though it goes without saying, maintaining the optimal performance of your slurry tank is essential for a seamless and productive farming experience.

The odd malfunction, however small, can disrupt the rhythm of your operations. Those seemingly innocent minor leaks can start snowballing and turn into major setbacks.

Here we’ll explore a few common troubles that may crop up with slurry tank care and of course, arm you with a few savvy troubleshooting solutions:

Agitator malfunctions: Ensuring optimal mixing

Your slurry mixer is responsible for breaking down solids and ensuring your mixture is entirely homogeneous. Any issues can lead to uneven nutrient distribution and sediment build-up – bad news for your slurry.

The best way to keep your mixer in good shape is to check the agitators are properly aligned and free from obstruction.

Next, give your blades a thorough once-over for any wear and tear, replacing any worn components promptly. Finally, make sure to grease and lubricate any parts to prevent friction-related issues and keep your mix smooth.

Leak detection: Preventing environmental contamination

Leaks are huge troublemakers, jeopardising both your slurry and the environment. When your tank’s integrity is compromised, you’re likely to lose out on valuable slurry and pollute the surrounding land with hazardous waste.

Stay ahead of the game with routine visual inspections. Sweep your tank with a discerning eye, scouting for cracks and any telltale signs of leakage.

Spotted some damage? Replace any damaged or worn seals right away to keep things secure.

Ensuring your farm is covered for common problems – such as leaks and cracks – is essential, otherwise you can rack up a hefty bill! Do your research and ensure your farm’s insurance covers all the essential stuff to give you peace of mind.

Odour control: Keeping the neighbours happy

Inadequate odour control and ventilation can lead to unpleasant working conditions, potential health hazards and a few unhappy neighbours…

The release of poisonous gases, such as hydrogen sulphide and methane, is one of the biggest dangers of improper slurry management. That means that your tank needs to have proper ventilation, covers and structural integrity to keep gases at bay.

Give your ventilation systems a routine check to ensure proper functioning, as well as using a robust slurry tank cover to keep everything under wraps. That way, you’ll be able to keep everyone on your farm and beyond happy and healthy.

Blockages: Promoting smooth flow

Clogs and blockages in outlet valves and pipes can impede drainage and disrupt flow, leading to sediment build-up and an inefficient, ineffective fertiliser.

But it’s not too tricky to keep things flowing.

The work starts before you’ve even begun. Before you introduce any slurry to the tank, take a step back and make sure you know what you’re doing. A consistent introduction is essential, followed by a proper mix to prevent clogs at the get-go.

Afterwards, frequently check outlet valves and pipes for obstructions or build-up. If necessary, flush the valves to dislodge or clear debris. Job done!

Slurry tank maintenance checklist

Clearly, slurry tank maintenance isn’t without its challenges. But fear not! Here’s a handy checklist to ensure your slurry tank remains reliable for the long haul:

1. Tank walls and linings: Regularly inspect for signs of corrosion, rust or deterioration to prevent structural damage.
2. Debris removal: Sediment and dirt accumulates easily in your slurry tank. Frequently remove debris to prevent clogs and promote effective waste breakdown.
3. Mixers: Check for proper functioning and alignment of your mixer to ensure it’s effectively breaking down solids and promoting even distribution
4. Seals: Inspect seals for any signs of wear, cracks or tears. Replace any damaged seals promptly to keep leaks at bay.
5. Covers and hatches: Examine these are all sealed properly to protect your slurry from the elements.
6. Valves: Inspect outlet valves and pipes for leaks or blockages to ensure proper flow and drainage from your tank.
7. Slurry: Test the nutrient and pH levels of your slurry to ensure both are at the desired levels to become an effective fertiliser.

By diligently following a few easy maintenance practices, you’ll not only extend the lifespan of your tank, but also contribute to a healthier and more efficient farming environment.
