Water Tank Price UAE: Common Questions Answered (2026)
Quick answer: Water tank prices in the UAE scale directly with capacity: a 500 litre tank costs roughly AED 340 to AED 650, a 1,000 litre tank costs AED 900 to AED 1,550 depending on shape and layer count, and a 10,000 US Gallon GRP tank costs AED 14,000 to AED 26,000. This guide answers the most common water tank questions UAE buyers search for, in plain terms.
Key Takeaways
- Price scales with capacity, material, layer count, and shape (vertical vs horizontal).
- A "water tank" in the UAE goes by several names: storage tank, overhead tank, cistern, poly tank, GRP tank, and more, depending on material and use case.
- UAE tanks are priced and sized in US Gallons (USG), not litres or Imperial gallons, which causes frequent confusion when comparing quotes.
- Polyethylene (plastic) covers small to mid capacities up to about 6,000 USG. GRP fiberglass covers mid to very large capacities, including 10,000 USG and beyond.
What Is the Price of a 1000 Litre Water Tank in the UAE?
A 1,000 litre (approximately 264 USG) UAE Municipality Certified plastic water tank costs AED 900 to AED 1,150 in a vertical configuration, and AED 1,350 to AED 1,550 in a horizontal configuration, depending on whether it is the standard 3-layer or the 4-layer insulated version.
| Shape | 3-Layer | 4-Layer Insulated |
|---|---|---|
| Vertical | AED 900 | AED 1,150 |
| Horizontal | AED 1,350 | AED 1,550 |
Horizontal tanks cost more than vertical tanks at the same capacity because they require more material and reinforced moulding to maintain structural strength lying on their side. For a full breakdown, including why "1,000 litre" and "1,000 USG" are frequently and mistakenly treated as the same tank (they are not: 1,000 USG holds 3,785 litres and costs AED 1,800 to AED 3,700), see our dedicated 1000 litre water tank price guide.
What Is a Water Tank Called?
A water tank goes by several different names in the UAE and internationally, depending on its location, material, and function, and all of them refer to the same basic concept: a container used to store water for later use.
Storage tank is the generic technical term used across the industry for any container holding water in reserve. Overhead tank or rooftop tank describes a tank mounted above the property, using gravity to help maintain water pressure at taps and fixtures below, the most common residential configuration in the UAE. Cistern is an older term, still used for underground or rainwater-collection tanks in some regions. Header tank or feed tank refers to a smaller tank that supplies a boiler, cooling system, or another piece of equipment rather than the whole property. Booster tank describes a tank paired directly with a pressure pump system.
Tanks are also commonly referred to by their material: a poly tank, plastic tank, or PVC tank is a polyethylene tank; a GRP tank or fiberglass tank is Glass Reinforced Plastic; an IBC tank is a portable Intermediate Bulk Container, typically 1,000 litres, used for transport and bulk storage rather than fixed installation; and a septic tank is a specific type of underground tank used for wastewater rather than potable water.
Interestingly, the Arabic word for tank or reservoir is khazzan (خزان), which is also the origin of the KHAZAAN brand name. Historically, water reservoirs and cisterns in the Gulf region were referred to using this term long before modern plastic and GRP tanks became standard, and it remains the everyday Arabic word used across the UAE for exactly this kind of water storage container.
What Is the Price of a 500 Litre Water Tank in the UAE?
A 500 litre (approximately 132 USG) UAE Municipality Certified plastic water tank costs roughly AED 340 to AED 650, depending on layer count. This capacity falls between two standard catalogue sizes, 100 USG (379 litres) and 200 USG (757 litres), with 150 USG (568 litres) being the closest single stocked size.
| Size | Litres | 3-Layer Price | 5-Layer Price |
|---|---|---|---|
| 100 USG | 379 L | AED 260 – 400 | AED 320 – 500 |
| 200 USG | 757 L | AED 420 – 650 | AED 520 – 800 |
A 500 litre tank is typically used as a small residential feed tank, a header tank for a single bathroom or kitchen supply, or for light commercial and irrigation applications where a full-size rooftop tank is not required. Contact KHAZAAN for a confirmed price on the exact closest stocked size to 500 litres.
What Is the Price of a 2,000 Litre Water Tank in the UAE?
A 2,000 litre tank converts to approximately 528 USG, which falls between two standard catalogue sizes: 500 USG (1,893 litres) and 1,000 USG (3,785 litres), with 500 USG the closest single stocked size.
| Size | Litres | Price Range (AED) |
|---|---|---|
| 500 USG | 1,893 L | AED 900 – 1,400 |
| 1,000 USG | 3,785 L | AED 1,800 – 3,000 |
For 2,000 gallons instead of litres, see our 2000 gallon water tank price guide. A tank close to 2,000 litres is typically priced near the 500 USG figure above, since 528 USG sits much closer to 500 USG than to 1,000 USG. Contact KHAZAAN for a confirmed price on the exact closest stocked size to 2,000 litres.
What Is the Price of a 10,000 Litre Water Tank in the UAE?
A 10,000 litre tank converts to approximately 2,642 USG, which falls between two standard catalogue sizes: 2,000 USG (7,571 litres) in polyethylene and 3,000 USG (11,356 litres) in GRP fiberglass, with 3,000 USG the closer single stocked size.
| Size | Litres | Material | Price Range (AED) |
|---|---|---|---|
| 2,000 USG | 7,571 L | Polyethylene | AED 3,500 – 5,500 |
| 3,000 USG | 11,356 L | GRP | AED 6,000 – 10,000 |
Note this is a different capacity from a "10,000 gallon" tank, covered separately below, which is nearly four times larger at 37,854 litres. Always confirm whether a quote refers to litres or US Gallons before comparing prices.
What Is the Price of a 10,000 Gallon Water Tank in the UAE?
In the UAE, "gallon" almost always means US Gallon (USG), not Imperial Gallon, since USG is the standard unit used by UAE tank manufacturers and suppliers. A 10,000 USG tank holds 37,854 litres. (For reference, if you specifically meant Imperial Gallons, 10,000 Imperial Gallons equals roughly 45,460 litres, or about 12,010 USG, a noticeably larger tank, so always confirm which unit a quote is based on.)
At 10,000 USG, polyethylene is no longer available. Polyethylene tanks top out at around 6,000 USG, so a tank at this capacity is manufactured in GRP fiberglass.
| Shape | Price Range (AED) |
|---|---|
| Vertical | AED 15,000 – 26,000 |
| Horizontal | AED 14,000 – 22,000 |
A 10,000 USG GRP tank is typically used for commercial and industrial applications: hotels, labour camps, factories, and large residential developments needing substantial central water storage. At this capacity, installations commonly involve crane placement and, in some cases, a hot press SMC panel tank system instead of a single-piece tank, particularly where site access is restricted. See our guides on GRP fiberglass tank pricing and commercial and industrial water tanks for more detail.

| 300 | 1,136 L | Polyethylene | AED 600 – 900 |
| 500 | 1,893 L | Polyethylene | AED 900 – 1,400 |
| 1,000 | 3,785 L | Polyethylene | AED 1,800 – 3,000 |
| 2,000 | 7,571 L | Polyethylene | AED 3,500 – 5,500 |
| 3,000 | 11,356 L | GRP | AED 6,000 – 10,000 |
| 5,000 | 18,927 L | GRP | AED 9,000 – 15,000 |
| 10,000 | 37,854 L | GRP | AED 15,000 – 26,000 |
| 20,000 | 75,708 L | GRP | AED 50,000 – 85,000 |
These figures exclude delivery and installation. Layer count (3-layer vs insulated 4-layer or 5-layer), horizontal vs vertical shape, and brand all move the final price within these ranges. For an exact quote on any capacity, contact KHAZAAN directly.

Q: How much does a 500 liter water tank for home cost? A: A 500 litre water tank for home use costs roughly AED 340 to AED 650 in the UAE, depending on layer count. This size falls between the 100 USG and 200 USG catalogue sizes, with 150 USG the closest single stocked tank.
Q: What is the price of a 10,000 litre water tank? A: A 10,000 litre tank converts to approximately 2,642 USG. The closest stocked catalogue size is 3,000 USG (11,356 litres) in GRP fiberglass, priced at AED 6,000 to AED 10,000. This is a different, much smaller capacity than a "10,000 gallon" (10,000 USG) tank, which holds 37,854 litres.
Q: How much does a 2000 liter water tank cost? A: A 2,000 litre tank converts to approximately 528 USG, close to the 500 USG catalogue size (1,893 litres), priced at AED 900 to AED 1,400. Contact KHAZAAN for a confirmed price on the exact closest stocked size.
Q: Why do water tank prices vary so much for what seems like a similar size? A: Price is driven by material (polyethylene vs GRP), layer count (3-layer vs insulated 4-layer or 5-layer), shape (vertical vs horizontal), brand, and certification status. Two tanks of the same litre capacity can differ significantly in price if these specifications differ.
Q: Is a "gallon" water tank the same everywhere? A: No. UAE suppliers price and size tanks in US Gallons (1 USG = 3.785 litres), not Imperial Gallons (1 Imperial Gallon = 4.546 litres). A "10,000 gallon" tank could mean two meaningfully different capacities depending on which unit is intended, so always confirm before comparing quotes.
Q: What is the smallest water tank size available in the UAE? A: Standard catalogue sizes start at 50 USG (190 litres), typically used as a small header or bathroom feed tank.
Q: What is the largest water tank size available in the UAE? A: Single-piece GRP tanks are available up to roughly 20,000 USG (75,700 litres) as a standard catalogue size, with larger custom and hot press panel tank systems available for industrial and infrastructure projects with no practical upper limit.
Q: Does "water tank" always mean a tank for drinking water? A: Not necessarily. The generic term covers potable water storage tanks, non-potable irrigation or fire-suppression reserve tanks, and septic tanks for wastewater. UAE Municipality Certification specifically applies to tanks intended for potable water storage.
Q: Why is the brand called KHAZAAN? A: Khazzan (خزان) is the Arabic word for tank or reservoir, the same everyday term used across the UAE for water storage containers. It reflects exactly what the business supplies.
