A GRP tank sized to what your site allows, at the capacity you need
We build each tank on one of seven fixed diameters, extend it to the length that gives your capacity, and place nozzles and partitions where you specify.
- 7 diameters, any length
- Drawing with the quote
- 25-year warranty
- Delivery to every region
We reply within one working hour, Saturday to Thursday.
Seven diameters, any length
Every tank we make sits on one of seven diameters: 1.20, 1.50, 1.80, 2.00, 2.40, 3.00 and 3.50 m. Length sets the capacity, so you are not limited to a catalogue list.
Give us the capacity and the longest length, widest diameter or tallest height your site allows, and we choose the diameter and length. That is how we have quoted sizes outside the chart, such as 2,800, 4,800 and 6,500 litres.

Narrow plot? A long, slim tank
Where a plot is tight between two walls, we build on a small diameter and extend the length: for example 6,500 litres on a 1.20 m diameter.
We have built slim tanks 1.20 to 1.40 m in diameter and close to 12 m long, moved by trailer and craned into city sites.
Box-shaped tanks
When a cylinder does not suit the site, we quote a box-shaped tank to your dimensions, with a drawing and installation guide.
A recent quote was for a tank 10 m long, 2 m wide and 2.1 m high, to the customer's dimensions.
Nozzles and partitions where you want them
Send what you know: capacity, the liquid to be stored, buried or above ground, the largest dimensions the site allows, and a sketch or site photo if you have one. Our draughtsman prepares a drawing of the tank, sent with the quote.
- Number and position of manholes
- Inlet and outlet sizes and positions
- Internal baffles or partitions into compartments
- Vents and lifting lugs
Delivery, placement and warranty
Custom tanks are delivered to any region of Saudi Arabia and placed by crane as a paid service on request, priced in the quote. You can also collect from the factory.
Excavation, base and backfill are your contractor's work under the installation guide we send with the quote; the 25-year warranty from the invoice date against manufacturing defects depends on following it.
Frequently asked questions
I need a capacity that is not in your chart. Can you build it?
Yes. Any capacity can be built on one of our seven diameters by changing the length. Tell us the capacity and the longest length or widest diameter the site allows.
How long does a custom size take?
Custom sizes take about a week, depending on the order.
Do you make square or rectangular tanks?
We quote box-shaped tanks to your dimensions, with a drawing and installation guide. Send the length, width and height available.
Will I see a drawing before production?
Yes. A drawing with dimensions and nozzle positions comes with the quote.
My plot is very narrow. How do I find the right size?
Measure the narrowest width of the pit or space and the longest run available, and include both in your request. We pick a diameter that fits and a length that gives your capacity.
Does the warranty cover custom tanks?
Yes. All our tanks carry the 25-year warranty against manufacturing defects, provided the installation guide is followed.
