Villa Water Tank Sizes in Dubai and How Many Tankers to Refill Them
By the Dubai Water Tankers team · Published · Updated
How do I know my villa water tank size and how many tankers it takes?
Measure the tank's inside length, width and water depth in metres and multiply them: the result is cubic metres, and each cubic metre is 1,000 litres or about 264 US gallons. Divide the litres by 9,464 to get the number of 2,500-gallon tanker loads. A 3 × 2 × 1.5 m tank holds 9 m³, just under one load.
- Volume (m³) = length × width × water depth (inside, in metres)
- 1 m³ = 1,000 L ≈ 264 US gallons
- One 2,500 US-gallon load ≈ 9.46 m³
- Never order more than the tank can hold

If you order more water than your tank can take, the driver stops when it’s full and the rest goes back on the truck. You’ve paid for water you didn’t get. Order too little, and you’re calling again in two days. Knowing your tank size once saves both problems.
Most Dubai villas have two tanks:
- an underground tank (the main store, filled by DEWA or a tanker), and
- a rooftop tank (a smaller tank the booster pump fills from below).
Tankers fill the underground tank. Its size is what you need.
Step 1: find the size on paper
Before you measure, check:
- the villa’s drawings or handover pack (the tank is often labelled with its capacity in gallons or m³);
- the developer’s or community’s FAQ for your villa type;
- your maintenance company’s tank cleaning report, which often lists the tank capacity.
Step 2: measure it yourself
If there are no papers, lift the tank cover and measure the inside with a tape:
- Length and width of the tank in metres.
- Depth from the floor of the tank to the overflow pipe, not to the lid. Water never rises above the overflow, so that’s your usable depth.
Multiply them: length × width × depth = cubic metres (m³).
For a round tank: 3.14 × radius × radius × depth.
Step 3: convert to gallons and loads
| Unit | Conversion |
|---|---|
| 1 m³ | 1,000 litres |
| 1 m³ | ≈ 264 US gallons |
| 1 US gallon | 3.785 litres |
| One 2,500-gallon load | ≈ 9,464 L ≈ 9.46 m³ |
Dubai tanker sizes are quoted in US gallons. Older villa drawings sometimes use imperial gallons (4.546 L), which are about 20% bigger. If your drawing says “2,000 gallons” and you’re not sure which, measure it.
Worked examples
| Inside size (L × W × water depth) | Volume | US gallons | Loads to refill from empty |
|---|---|---|---|
| 2.5 × 2 × 1.2 m | 6 m³ | ≈ 1,585 gal | A 1,000 + 500-gal drop, topped up by the mains |
| 3 × 2 × 1.5 m | 9 m³ | ≈ 2,378 gal | One 2,500-gal load |
| 4 × 2.5 × 1.5 m | 15 m³ | ≈ 3,963 gal | A 2,500 + 1,000-gal drop, topped up by the mains |
| 5 × 3 × 1.8 m | 27 m³ | ≈ 7,133 gal | Three 2,500-gal loads |
These are examples to show the maths, not typical sizes for any community.
Refilling a half-empty tank
You rarely refill from empty. Measure the empty depth (from the water surface down to the overflow level), multiply by length × width, and order that. If the tank is 3 × 2 m and the water is 0.8 m below the overflow, you need 3 × 2 × 0.8 = 4.8 m³, about 1,270 gallons.
Tell us the size once
When you order, send the tank size or a photo of the opening with a tape measure in it. We’ll suggest the right load, and for regular customers we keep the size on file so the next villa tank refill is a one-line message. Not sure which truck to send?
