Are you stuck choosing between concrete and plastic water storage tanks? Sure, the price tag matters, but have you thought about which one will actually save you money in the long run? Let’s talk about it.
I get it – when you’re looking at water tanks, the first thing you check is the price. But here’s the thing – sometimes what looks cheaper now might cost you more later. Today, we’ll break down everything about concrete and plastic tanks, especially focusing on your wallet (both now and later!).
Cost Comparison: Plastic vs Concrete Water Storage Tanks
Hey, looking at prices between plastic and concrete tanks? I’ve got all the numbers right here. Let’s break this down in a way that actually makes sense.
Let’s first look at this comparison table:
| Tank Size (Litres) | Plastic Tank Cost | Concrete Tank Cost |
|---|---|---|
| 100-115 | £79.20 | £20-£70 |
| 200-250 | £110.40-£146.40 | £80-£200 |
| 300-350 | £128.10 | £200-£300 |
| 500 | Up to £514.80 | £300-£500+ |
| 1000 | £200.40-£287.99 | Additional costs* |
| 1700 | £648+ | Additional costs* |
*For concrete tanks above 500L, you need to consider:
- Ready-mix concrete: £100-£160 per cubic meter
- Delivery cost: Around £150
- Installation: £300-£1,500
- Pouring cost: £80-£90 per m³ (C8/C10/C15 grades)
- Or £90-£95 per m³ (C20/C25 grades)
Now, let’s talk about what these numbers really mean for your pocket.
The Hidden Story Behind These Prices
- Initial Purchase Cost, at first glance, concrete tanks might look cheaper for smaller sizes. You can see this clearly in the 100-115 litre range where concrete costs £20-£70 while plastic is at £79.20. But here’s the catch – that’s not the whole story.
- Installation Reality Here’s something most people don’t think about right away. With plastic tanks, installation is pretty straightforward. But with concrete? You’re looking at extra costs:
- Installation fees: £300-£1,500 (varies based on size)
- Delivery of ready-mix concrete: About £150
- The actual concrete pouring: £80-£90 per cubic meter
- Plus, you might need specialized equipment
- Size Matters For bigger storage needs, things get interesting:
- Plastic tanks become more straightforward in pricing as you go up in size
- A 1000L plastic tank costs between £200.40-£287.99
- Concrete tanks above 500L need custom calculations including material, labor, and installation
- For really big storage (10,000L+), concrete offers modular units, but remember to add all those extra costs
- Long-term Cost Factors Here’s what you need to think about for the future:
- Concrete tanks:
- More durable against weather
- Can last longer with proper maintenance
- But repairs are expensive and complicated
- Might need specialized treatments to prevent water seepage
- Could crack in freezing conditions if not properly maintained
- Plastic tanks:
- Usually cheaper to repair
- Easier to replace if needed
- Less likely to develop leaks
- Don’t need special treatments
- But might need replacement sooner than concrete
- Special Considerations If you’re thinking about specialized systems, keep this in mind:
- Storage tank costs can jump 2-10 times higher for specialized systems
- Concrete septic tanks typically run £700-£1,300
- Plastic tanks with special features (like UV protection or extra durability) will cost more than basic models
- Real Talk About Value Let’s get real about what you’re actually paying for:
- With concrete, you’re investing in something that could last longer but costs more to maintain
- With plastic, you’re getting something easier to manage but might need replacement sooner
- For smaller storage needs (under 500L), plastic often works out cheaper when you add up all the concrete installation costs
- For larger storage (1000L+), you need to do some serious math about your long-term plans
Maintenance and Ongoing Costs: The Real Story
| Maintenance Task | Plastic Tanks | Concrete Tanks |
|---|---|---|
| Inspection Visits | £100-£300 | £100-£300 |
| Annual Cleaning | Around £400 | Around £400 |
| Basic Repairs | £100-£500 | £100-£500 |
| Major Repairs | £1,000+ | £1,000+ |
| Cleaning Frequency | Every year | Every 1-5 years |
| Inspection Frequency | Every 6 months | Twice yearly |
Regular Check-ups: What You Need to Do
For plastic tanks, you’ve got to keep an eye out for some specific things. Think of it like taking care of your car – regular checks save you money in the long run. You need to watch for any weird bulging, stress marks, or cracks in the surface. The good thing is, these issues are usually pretty easy to spot.
With concrete tanks, it’s a bit different. You’re looking for cracks, sure, but also any signs of water seeping through. The tricky part with concrete is that small problems can turn into big ones if you don’t catch them early.
The Cleaning Story
Here’s something most people don’t think about until it’s too late – both types need regular cleaning, but there’s a difference in how often. Plastic tanks need a good clean every year. You’ve got to drain them completely and scrub out any algae that’s built up. Plus, you need to check those filters and valves regularly.
Concrete tanks can go a bit longer between cleanings, sometimes up to 5 years. But when they do need cleaning, it’s usually a bigger job. You’re looking at removing sediment that’s really had time to settle in.
Hidden Costs You Need to Know About
Let’s talk money – because there’s more to it than just the cleaning and inspection costs. With plastic tanks, you might need to deal with:
- Filter replacements
- UV protection renewal
- Pest prevention measures
- Water quality testing
For concrete tanks, you’re looking at:
- Structural integrity checks
- Crack sealing
- Reinforcement work
- Water quality monitoring
Making It Last: The Maintenance Game Plan
For both types, keeping a maintenance log is super important. It helps you track what’s been done and spot any patterns in problems. Think of it like keeping service records for your car – it helps you stay on top of things and can save you money in the long run.
With plastic tanks, you want to check them every six months at least. Look for signs of damage, make sure the valves work right, and keep an eye out for any pests trying to make your tank their home.
Concrete tanks need checking twice a year too, but you’re mainly looking for structural issues. Any cracks need fixing right away – if you let them go, they can turn into bigger problems that cost way more to fix.
The Smart Owner’s Approach
Here’s what I tell everyone – set up a proper maintenance schedule from day one. Whether you go with plastic or concrete, regular maintenance is always cheaper than emergency repairs. Plan for your annual or bi-annual inspections, budget for regular cleaning, and keep some money aside for those unexpected repairs.
Remember, both types of tanks can last a long time if you take care of them properly. The key is staying on top of the maintenance and not skipping those regular checks just to save a few quid. In the long run, good maintenance is always cheaper than replacing a tank that’s failed because nobody looked after it.
Lifespan and Durability: Getting Your Money’s Worth
Look, when you’re spending money on a storage tank, you want to know how long it’ll last, right? Let me break this down for you in a way that makes sense.
Here’s a simple comparison table to show you what you’re really getting:
| Factor | Plastic Tanks | Concrete Tanks |
|---|---|---|
| Average Lifespan | 10-15 years | 20-30 years |
| Maximum Potential | Up to 20 years | 30-60+ years |
| Maintenance Needs | Regular checks | Heavy maintenance |
| Common Issues | UV damage, temperature cracks | Structural cracks, leaks |
| Early Signs of Failure | Color changes, brittleness | Hairline cracks, seepage |
| Repair Difficulty | Generally easier | Complex and expensive |
Now, let’s talk about what this really means for you.
What You Get With Plastic Tanks
Think of plastic tanks like a reliable car – they’ll serve you well for about 10-15 years if you treat them right. Some can even push to 20 years, but that’s if you’re really taking care of them. The thing with plastic tanks is they’re kind of like your skin in the sun – they need protection. Without good UV stabilizers, they’ll age faster, just like you’d get sunburned without sunscreen.
The good news? You can usually spot problems early. The plastic might start changing color or feeling different – that’s your warning sign to start planning for a replacement. It’s not like you’ll wake up one day to find your tank has completely failed.
The Concrete Story
Now, concrete tanks are more like a well-built house – they’re in it for the long haul. We’re talking 20-30 years minimum, and some of these tanks are still going strong after 60 years. That’s pretty impressive, right? But here’s the catch – they need serious attention to get to those big numbers.
Think about it like this: a concrete tank is only as good as its installation. Get that wrong, and you might as well cut its life in half. And just like a house, you can’t just build it and forget about it. These tanks need regular check-ups to spot any cracks or leaks before they become big problems.
More Talk About Maintenance
Here’s something most people don’t think about until it’s too late. With plastic tanks, maintenance is pretty straightforward. You can see what’s going on, repairs are usually simple, and if something goes wrong, replacement parts are easy to find.
Concrete’s a different story. When these tanks need fixing, it’s usually a bigger job. We’re talking about dealing with cracks that can let bacteria grow, handling seismic activity effects, and managing temperature changes that make the concrete expand and contract. It’s not impossible to maintain, but it’s definitely more involved.
Remember, these lifespans aren’t set in stone. How you use your tank, where you put it, and how well you maintain it all play a part. Just like anything else, the better you look after it, the longer it’ll last.
And here’s a tip most people miss – don’t wait until your tank starts failing to think about replacement. Start planning a few years ahead. This way, you’re not rushed into a decision when your tank suddenly develops issues. For plastic tanks, start thinking about replacement options around the 8-10 year mark. For concrete, get serious about thorough inspections after 15-20 years.
Underground vs. Above-Ground: Making the Smart Choice
Let’s dig deep into what you need to know about putting these tanks above or below ground. Trust me, this isn’t just about where you stick your tank – it’s about making your life easier and your wallet happier.
Underground Plastic Tanks
Look, putting a plastic tank underground might seem scary, but there’s more to this story. Here’s what you need to know:
Installation and Setup
- Need special reinforced plastic tanks (don’t even think about using regular ones)
- Usually comes with installation guides but needs professional fitting
- Requires proper ground assessment before digging
- Must have the right backfill material (usually gravel or sand)
- Costs extra for excavation work (around £500-£1,000 depending on size)
Peace of Mind Factors
- Protected from weather changes and UV damage
- Less visible (great if you care about how your property looks)
- Saves space in your garden or property
- Temperature stays more stable (good for water quality)
- But… harder to spot leaks or damage early on
Maintenance Reality
- Needs regular professional checks (at least yearly)
- Repairs can be tricky and expensive (because it’s underground)
- Might need a pump system for water access
- Could face issues with tree roots or ground movement
- Higher risk of contamination if not properly sealed
Underground Concrete Tanks
Now, concrete underground is a different game altogether. Let’s break it down:
Structure and Durability
- Naturally suited for underground installation
- Can handle soil pressure better than plastic
- Less likely to float in high water tables
- Excellent for long-term storage solutions
- Typically lasts 30+ years if installed correctly
Installation Considerations
- Needs serious groundwork preparation

- Might need shade or covers
- Temperature fluctuations can affect water quality
- Risk of damage from accidents or vandalism
Above-Ground Concrete Tanks
These aren’t as common, but they have their place:
Construction and Setup
- Needs solid foundation preparation
- Usually built on-site
- Requires professional construction team
- Higher initial setup costs
- Must have proper reinforcement
Advantages Worth Noting
- Extremely durable against weather
- Great for very large storage needs
- Can be customized during construction
- Less affected by temperature changes
- Lower risk of accidental damage

- Visual impact on property
Making Your Choice: The Smart Way
Think about these key points before deciding:
Property Considerations
- Available space (above or below ground)
- Soil type and ground conditions
- Local weather patterns
- Access for maintenance
- Future property plans
Budget Reality Underground installations (both materials):
- Extra costs for excavation
- Potential drainage systems
- Professional installation required
- Regular professional maintenance
- Higher repair costs if things go wrong
Above-ground options:
- Lower installation costs
- Easier maintenance access
- DIY potential for some tasks
- More flexible for future changes
- But might need extra protection
Long-term Thinking
- How long do you plan to stay at the property?
- What’s your maintenance budget?
- Do you need easy access to the tank?
- Are you okay with visible storage solutions?
- What’s the total capacity you’ll need?
Remember, the cheapest option now might not be the smartest choice for the long run. Think about your specific situation – like if you’ve got limited garden space, maybe an underground tank makes more sense even if it costs more upfront. Or if you’re not planning to stay in the property long-term, an above-ground plastic tank could be your best bet.
Want my honest take? The decision between underground and above-ground isn’t just about money – it’s about what works best for your specific situation. Just make sure whatever you choose, you’re thinking about both the short-term and long-term impacts on your property and your wallet.
Sustainability: Making the Smart Environmental Choice
Look, when we talk about water storage tanks, it’s not just about holding water – it’s about being smart with our resources. Let me tell you why this matters more than you might think.
These days, you can make any tank smarter by use of smart water tank level indicators. They’re not even that expensive anymore – we’re talking about devices that can tell you exactly how much water you’re using and when you need more. Think about it like having a fuel gauge for your water. You can get alerts on your phone when levels are low, track your usage patterns, and even spot leaks before they become a problem.
The Green Angle
Here’s something interesting about both types of tanks:
Plastic Tanks:
- Made from materials that can be recycled
- Lighter to transport (means less fuel used)
- Can be melted down and reused when they’re done
- But they do come from oil-based materials
Concrete Tanks:
- Use natural materials
- Last longer (less frequent replacement needed)
- Can be crushed and recycled as aggregate
- Better temperature regulation (less energy needed for water treatment)
Water Conservation Tips
When you’ve got a storage tank, you’re already halfway to being more water-efficient. Here’s how to take it further:
- Use rainwater harvesting systems with your tank – it’s basically free water from the sky
- Install water-efficient fixtures to make your stored water last longer
- Set up a smart monitoring system to track usage
- Plan your garden watering based on tank levels
- Check weather forecasts to optimize water collection
Looking to the Future
Want to really make a difference? Think about connecting your tank to a larger system. You could:
- Link it to solar panels for pump operation
- Set up automated irrigation systems
- Use smart meters to track and reduce usage
- Create a greywater recycling system
The Community Impact
Here’s something most people don’t think about – when you store and use water efficiently, you’re helping your whole community. Less strain on the main water supply means better water pressure for everyone, lower costs in the long run, and a more resilient system during droughts or shortages.
Remember, whichever tank you choose, the real sustainability comes from how you use it. A well-maintained tank with smart monitoring is better for the environment than a high-tech solution that’s poorly managed. Think long-term, plan your usage, and keep an eye on those water levels. That’s how you make a real difference – both for your wallet and for the planet.
Think Smart, Act Green
At the end of the day, a water storage tank isn’t just about storing water – it’s about being part of the solution. Whether you go for plastic or concrete, adding smart monitoring and thinking about sustainability means you’re not just saving money – you’re helping save the planet too. And isn’t that worth thinking about when you’re making your choice?
