GRP water tanks for farms: well and irrigation storage that never rusts
We size the farm tank to your well pump or tanker load, above ground or buried, and deliver it to your farm in any region.
- No rust
- 25-year warranty
- Up to 100,000 L per tank
- Delivery to every region
We reply within one working hour, Saturday to Thursday.
Size from the well or tanker, not from headcount
A farm tank is sized from the water source and the irrigation schedule; send us the numbers and we will help.
- From a well: pump output in litres per hour × the pumping hours you want to store. A pump giving 5,000 L/h for 4 hours needs about 20,000 litres.
- From a tanker: tanker load × the number of loads the tank should take, so a full load empties without waiting.
- For irrigation: the water the schedule needs between fills.
- For the farmhouse: occupants × 150 to 250 litres per person per day × two or three days of reserve.

Sun and heat on open ground
A farm tank stands in the sun all year. GRP does not rust or corrode, and the opaque wall keeps light out, so algae cannot grow inside a closed tank.
Water in an above-ground tank warms in summer like any exposed tank; for the farmhouse supply, a buried tank stays cooler.
GRP is lighter than concrete, so a tank can be moved elsewhere on the farm if the irrigation plan changes.
Above ground or buried?
For irrigation a large above-ground tank on a level base usually suits: faster to install and easier to inspect. We build large horizontal tanks on GRP saddles.
A buried tank suits the farmhouse supply and needs a block-walled pit and concrete slab per the installation guide. In wadis or where groundwater is high, consult your contractor before burying.
| Capacity | Diameter | Approx. length |
|---|---|---|
| 20,000 L | 2.00 m | 6.50 m |
| 30,000 L | 2.40 m | 6.50 m |
| 50,000 L | 3.00 m | 7.40 m |
| 75,000 L | 3.50 m | 8.00 m |
Delivery to the farm, and a diesel tank for the pump
We deliver from our Dammam factory with our own trucks or carriers, or you collect. Send a map pin and the track condition: tanks of 3.00 m diameter and above need a low-bed and a wide gate.
Crane placement is a paid service priced in the quote. If the well pump runs on diesel, we also build above-ground diesel storage tanks to order, which can go on the same quote.
Frequently asked questions
Will the tank last years in the farm sun?
GRP does not rust like steel, and the opaque wall keeps light off the water. The 25-year warranty covers manufacturing defects, subject to the installation guide: a level base above ground, the burial conditions below.
Can I connect several tanks?
Yes. Two or more tanks instead of one very large one are easier to transport and clean. We fit the inlets and outlets on each tank to the connection layout you want.
Will the water taste change?
Algae cannot grow without light, and the wall is opaque. Keep the cover closed and clean through the manhole every six months.
How soon can I have the tank?
Common sizes are in stock; other sizes take about a week, depending on the order.
Can I collect it myself?
Yes, from our factory in Dammam Third Industrial City; we load the tank onto your truck at the factory.
