What is a concrete water tank for?
A reinforced concrete water tank is a built reserve, constructed on site with a reinforced floor slab and walls, which stores the irrigation water for your finca so you can use it when you need it. In the Axarquía it's the most common way of not depending on your irrigation turn: water from the irrigation community, the well or the rain goes into the tank and you water at your own pace, by drip or with a pump.
Being reinforced concrete, it withstands the pressure of the water and the soil, doesn't warp in the sun and lasts for decades with minimal maintenance. We also build it to measure: the size, shape and height your plot allows, making use of the slope when possible to irrigate by gravity.
If you're looking for a concrete cistern (aljibe) or a built irrigation tank, it's all the same: we build it from start to finish, from the excavation to the lid.
What do our customers use it for?

Buried, semi-buried or above-ground tanks
The location, the slope and machinery access decide which tank suits you. We look at it on the visit and propose the option that best fits your plot.

Buried tank
It sits underground and only the access hatch is visible. The water stays cool and dark, free of algae, and you can have a terrace, parking or garden on top. It's the classic country house cistern.

Semi-buried tank
It's set into the bank, making use of the slope. Less excavation than a buried tank and, if it's on the upper part of the finca, it lets you irrigate by gravity and save on a pump.

Above-ground tank
On a reinforced floor slab, usually circular, which spreads the water pressure better. It's the option for large irrigation volumes and the easiest to inspect and maintain.
We also build them rectangular or square when you need to make use of a corner of the plot, and with a concrete roof or open, depending on the use.
What our irrigation tank includes
We do the whole job, without you having to coordinate anyone else. Excavation, steel fixing and concrete pouring are done with our own machinery and team, and we hand it over ready to fill.
What we do:
- Setting out and excavation with our own machinery
- Reinforced concrete floor slab
- Reinforced concrete walls (steel fixing and shuttering)
- Internal waterproofing
- Lid and access hatch
- Inlet and outlet pipes, and connection to your irrigation
- Overflow and bottom drain for cleaning
- Backfill and compaction around it
- Removal of surplus soil
The tank is designed for the volume you need: a cubic metre of water weighs a tonne, so the reinforcement and wall thickness are never improvised.

How we build a concrete water tank
A tank has to hold tonnes of water for many years. That's why we always follow the same build sequence:
1. VISIT AND MEASURING: We look at the site, the access for machinery and where the water comes from. We talk about the m³ you need.
2. FIXED QUOTE: We give you a fixed written price, according to the size and type of tank.
3. EXCAVATION: We excavate and level the base with our own machinery. Surplus soil is removed or reused on the finca.
4. REINFORCED FLOOR SLAB: We place the steel and pour the base slab, which spreads the whole weight of the water.
5. REINFORCED WALLS: Shuttering, steel fixing and pouring of the walls, leaving openings for pipes, overflow and drain.
6. WATERPROOFING: We treat the inside so it doesn't lose water and fit the lid, hatch and connections.
7. TEST AND HANDOVER: Backfill and compaction outside, a test fill and handover of the tank ready for irrigating.

What size tank do I need?
The sum is simple: 1 m³ is 1,000 litres. Multiply what you irrigate per day by the number of days you want in reserve, or think about the volume of your irrigation allocation. Some examples of internal dimensions:
Rectangular 5 × 4 m with 2 m of water. About 40,000 litres: a good reserve for a medium-sized plot.
Circular, 6 m in diameter with 2.5 m of water. About 70,000 litres for fruit farms.
Made to measure. For large farms we design the tank around your real consumption and the space available.
Not sure how much you need? Tell us what you irrigate (number of trees or area) and how often you get your water allocation, and we'll help you size it on the visit.
Concrete or polyester tank: which suits me?
For a few thousand litres, a prefabricated tank may be enough. When it comes to proper irrigation reserves, reinforced concrete wins:
| Reinforced concrete | Polyester / plastic | |
|---|---|---|
| Lifespan | Decades, it's a solid build | Shorter: sun and knocks damage it |
| Size | Made to measure, with no practical limit | Catalogue sizes |
| Buried | Yes, it withstands the pressure of the soil | Only specific models |
| Shape | Adapts to the space and the slope | Fixed |
| On top | Can take a slab, terrace or garden | No |
| Transport | Built on your finca | Has to be delivered and lifted in by crane |
| Investment | Higher at first, better in the long run | Lower for small volumes |
Concrete water tank prices
The price of a reinforced concrete tank is calculated according to the m³ and the work your plot needs. We don't give rough prices off the cuff: we come and look with no obligation and give you a fixed quote. These are the factors that decide it:
CAPACITY (M³): It's what counts most in the price: more volume, more concrete and more steel.
BURIED OR ABOVE GROUND: Burying it means more excavation and soil removal.
MACHINERY ACCESS: Narrow tracks or sloping farms make transport more expensive.
TYPE OF GROUND: Rock, loose soil or fill change the excavation and the base.
ROOF: Open, with a lid or with a concrete slab you can walk on.
CONNECTIONS: Pipes, pump, filters or connection to your drip irrigation.
NO-OBLIGATION QUOTE: ask us for a quote or send us the m³ and a photo of the site on WhatsApp. We'll come and look and give you a fixed written price.

Concrete water tank FAQs
How much does a concrete water tank cost?
The price of a reinforced concrete water tank depends mainly on the cubic metres, whether it's buried or above ground, machinery access and the ground. That's why we don't give rough prices: we come and see the site with no obligation and give you a fixed written quote.
Is a concrete or a polyester tank better?
For small volumes a polyester tank can do the job. For irrigation reserves of several tens of m³, a reinforced concrete tank lasts much longer, is made to fit the site, can be buried and withstands sun and knocks without warping.
Do I need a licence to build a water tank on my finca?
Normally yes: a concrete tank is a construction and the town hall usually asks for a licence or a responsible declaration, especially on rustic land. Each municipality has its own requirements, so it's best to check before starting; we'll guide you on the documents usually requested.
How long does a reinforced concrete tank last?
A well-designed, well-poured reinforced concrete tank, waterproofed on the inside, lasts for decades. Maintenance is minimal: an occasional clean through the bottom drain and checking the internal waterproofing if a leak ever appears over the years.
Can the tank be used for drinking water?
Our tanks are designed for irrigation water. If you want to store water for human consumption, the inside needs a lining suitable for drinking water and appropriate water treatment; mention it on the visit and we'll take it into account.
Buried or above ground?
A buried tank takes up no space and keeps the water cool and free of algae, but needs more excavation. An above-ground tank is easier to build and inspect, and on a hillside a semi-buried tank on the upper part lets you irrigate by gravity. We decide together after seeing your finca.
