Vertical GRP water tanks for villas and roofs, from 2,000 to 100,000 litres
A standing tank whose footprint is just its diameter, made to order in our Dammam factory on the diameter your space allows and the height your capacity needs.
- 25-year warranty
- Small footprint
- 2,000 to 100,000 L
- Delivery to every region
We reply within one working hour, Saturday to Thursday.
Why villa owners choose a vertical tank
A vertical tank stands on its base and occupies only a circle of its own diameter. A 5,000-litre tank, for example, is 1.50 m across and 3.10 m tall when vertical, while a horizontal tank of the same capacity can be up to 4.50 m long.
GRP does not rust or corrode, and the white wall is opaque, so no light gets in, algae cannot grow and the water keeps its taste.
- Bottom outlet near the base
- Manhole for cleaning
- Inlets and vent at the sizes you specify
- Any capacity between chart sizes, since every tank is made to order

Pick the diameter that fits your space
Vertical tanks are built on fixed diameters, and the height grows with capacity. The figures below come from our size chart; sizes in between are made to order.
At the large end we have built, for example, a 75,000-litre vertical tank 3.50 m in diameter and 8 m tall.
| Diameter | Capacity range | Approx. height |
|---|---|---|
| 1.20 m | 2,000 to 3,000 L | 1.95 to 2.70 m |
| 1.50 m | 4,000 to 6,000 L | 2.55 to 3.50 m |
| 1.80 m | 5,000 to 11,000 L | 2.20 to 4.50 m |
| 2.00 m | 10,000 to 15,000 L | 3.50 to 5.10 m |
| 2.40 m | 15,000 to 30,000 L | 3.50 to 6.75 m |
| 3.00 m | 30,000 to 50,000 L | 4.65 to 7.50 m |
| 3.50 m | 50,000 to 100,000 L | 5.60 to 10.80 m |
Before it goes on the roof: load and lifting
Every 1,000 litres of water weighs about a tonne, so a full 5,000-litre tank puts more than 5 tonnes on the roof. Ask the building's engineer to confirm the slab can carry that load where you plan to put it.
The installation guide requires a level, even base and nothing placed on the tank.
- Measure the route to the tank position: gate, corridor, stairs and roof opening, against the tank's diameter and height.
- If the tank will not pass the stairs, it is lifted by crane from the street. Crane placement is a paid service on request.
- Check that the street has room for the truck and crane beside the house.
Delivery and warranty
Common sizes are in stock; other sizes take about a week, depending on the order. We deliver to every region, with delivery and crane costs in the quote, or you can collect from the factory.
The factory guarantees the tank for 25 years from the invoice date against manufacturing defects, provided the installation guide is followed.
Frequently asked questions
How many litres does my house need?
Multiply the people in the house by 150 to 250 litres a day, then by two or three days of reserve. A family of six usually needs 2,000 to 4,500 litres. Do not oversize: water that stands too long loses quality.
Can my roof carry the tank?
Your building engineer decides. Count a tonne for every 1,000 litres of water, add the tank's own weight, and choose a spot the slab can carry.
How does the tank get onto the roof?
If it will not pass the stairs and roof opening, it is lifted by crane from the street. Crane placement is a paid service, priced in the quote.
Will the water get hot on the roof?
Any tank in the sun runs warmer than a buried one. Put it in shade where you can; if cool water matters most, a buried tank is the better choice.
Vertical or horizontal?
Vertical takes less ground and suits narrow yards and roofs. Horizontal is lower and suits places that cannot take the height. Tell us the space and height available and we will suggest one.
How soon can I get it?
Common sizes are in stock; other sizes take about a week, depending on the order.
