Wondering which type of water tank is better for your property?
This guide explains the differences between aboveground and underground water storage tanks in the UAE. We’ll cover installation, maintenance, cleaning, pros and cons, and how to choose the right one for your space and budget.
What Are Above-Ground and Underground Water Tanks?
Above-ground tanks are installed on a visible surfaces like rooftops, side yards, or concrete platforms. These tanks are commonly used in homes, farms, and commercial properties due to their easy access and installation.
Underground tanks are installed under the ground. They’re suitable for small spaces or when you want a cleaner and more hidden setup. They’re often used in villas, warehouses, and commercial buildings.
How Is a Water Storage Tank Installed in the UAE?
Above-Ground Tank Installation Process
• Requires a flat and stable surface
• No excavation needed
• Low-cost and quick to install
Underground Tank Installation Process
• Requires excavation and machinery
• Needs proper backfill (usually sand)
• Higher installation cost and time
For homeowners looking for minimal disruption and lower installation fees, above- ground tanks are easier. Underground tanks, while more involved, help maximize outdoor space and visual appeal.
Which Water Tank Is Easier to Maintain?
| Factor | Above-Ground Tank | Underground Tank |
|---|---|---|
| Ease of Inspection | Simple, everything is visible | Harder, requires access lids |
| Repair Access | Fast and accessible | May need digging |
| Durability | Exposed to sun/weather | Protected from elements |
In short, aboveground tanks are easier to maintain. Underground tanks stay protected, but any repair job may require more work.
How Do You Clean Above-Ground and Underground Water Tanks?
Cleaning Above-Ground Water Tanks
• Drain the tank completely
• Open the lid or manhole
• Use a long brush and mild, non-toxic cleaner
• Rinse thoroughly and refill
• Recommended every 6 to 12 months
Cleaning Underground Water Tanks
• Often requires professional help
• Drain water using a submersible pump
• Open sealed access cover
• Use high-pressure spray to clean internal walls
• Inspect for mold, cracks, or root damage
• At least once a year is ideal
Both tank types require regular cleaning to avoid bacteria buildup. Above-ground tanks
are simpler to handle yourself. Underground tanks may need expert cleaning services.
Pros and Cons Comparison: Which Water Tank Is Better?
| Feature | Above-Ground | Underground |
|---|---|---|
| Installation Cost | ✅ Low | ❌ High |
| Maintenance Access | ✅ Easy | ❌ Complex |
| Aesthetics | ❌ Visible | ✅ Hidden |
| Temperature Control | ❌ Heats up in sun | ✅ Cooler underground |
| Space Efficiency | ❌ Takes up space | ✅ Saves space |
| Cleaning | ✅ DIY-friendly | ❌ Often professional only |
Which One Is Right for You?
If you’re looking for something simple, affordable, and easy to maintain, above-ground tanks are your best bet. They’re great for villas, farms, and projects where space isn’t a major concern.
But if your goal is to save space, keep your property looking clean, or store water in cooler conditions, underground tanks make a strong case. They are perfect for urban buildings, hotels, or anyone wanting a more discreet solution.
Still unsure? Think about:
• How much space you have
• Your installation budget
• Whether you’ll clean it yourself or hire someone
• Local regulations (like DEWA approvals in Dubai)

Frequently Asked Questions (FAQ)
1. Can underground water tanks be used above ground?
Generally, no. Underground tanks are designed to handle pressure from surrounding soil, not exposure to direct sunlight or surface impact. If placed above ground, they may become unstable or get damaged. It’s best to use tanks specifically designed for aboveground use.
2. Which is better, an aboveground or underground water storage tank?
It depends on your space, budget, and preferences.
• Above-ground tanks are easier to install and maintain.
• Underground tanks save space and look cleaner but cost more to install.
If you want quick setup and easy access, go for aboveground. If you need to save space or want a hidden solution, underground is better.
3. What is the maximum depth of an underground water tank?
Most underground tanks are installed at depths between 1 to 2.5 meters. However, the actual depth depends on the tank design, local soil conditions, and site layout. Deeper installations may require special engineering and support.
4. What is the ideal underground water tank size?
The ideal size depends on your water usage. For homes, a tank between 1,000 to 5,000 liters is common. For commercial or industrial use, it can go up to 10,000 liters or more. It’s always best to calculate based on daily usage and local regulations.
