Are you still allowed to fill your pool on Mallorca in 2026? The answer depends on where you live. Because of the ongoing water shortage, several municipalities have restricted or completely banned filling pools from the public mains, while others cap consumption per household. If you want to fill or top up a pool now, you should know your municipality's rules, plan for the tanker truck alternative, and reduce your pool's water consumption in general. Here you will read what this means for your running costs on Mallorca and how a delivery by Cuba de agua works.
At a glance
Parts of Mallorca are at the Prealerta drought pre-warning level in 2026. Deià bans filling private pools from the mains year-round, and Esporles has capped consumption in two residential areas at 340 liters per household per day. Whether you are allowed to fill from the tap or switch to a tanker truck, expect to pay a low three-figure amount depending on volume and distance.
Water shortage on Mallorca 2026: how serious the situation is
The Balearic Islands measure drought with an official index that is updated every month. In June 2026, Mallorca's water reserves stood at 46 percent, and over 80 percent of the Balearic land area was in Prealerta, with another roughly 10 percent already in Alerta. You can find the current status for your municipality in the drought index of the Balearic water portal, which the regional government updates monthly with groundwater and reserve data.
Important to understand: the Prealerta and Alerta levels do not trigger automatic, island-wide bans. Whether you may fill your pool is decided by your municipality through a local ordinance (Bando or Ordenanza). That is why something can be allowed in Santanyí that is banned in Deià. The municipalities in the Serra de Tramuntana and in the Pla are traditionally the hardest hit, because they depend on local springs and wells.
Which municipalities restrict pool filling
The situation changes constantly, but a few examples show the range of measures:
- Deià bans filling private pools from the public mains year-round, as well as washing cars and terraces with drinking water.
- Esporles has capped consumption in two residential areas at 340 liters per household per day. Violations can bring fines of up to 2,500 euros.
- Other Tramuntana municipalities such as Valldemossa or Banyalbufar regularly issue time-limited restrictions on garden irrigation and pools in dry summers.
- Palma currently has no filling bans, but the utility EMAYA is calling on residents to save water and publishes saving tips and information on the water supply for the city.
Warning: check your municipality's Bando
Violating a municipal water ordinance is no trivial matter. Depending on the municipality and the severity, fines run into four figures. Before filling, check the website or the notice board of your town hall (Ajuntament) and ask in writing if in doubt.
Am I allowed to fill my pool on Mallorca in 2026? That depends on your municipality. Without a local restriction, yes; in municipalities like Deià, filling from the mains is banned. Delivery by tanker truck usually remains permitted there, because it does not draw on the municipal drinking water network.
Water delivery by tanker truck: process and costs
A Cuba de agua is a tanker truck that delivers drinking or non-potable water directly to households. On Mallorca the trucks typically deliver 8,000 to 12,000 liters per trip into a cistern or pool and charge per delivery, not per cubic meter like the mains connection.
This is how an order works:
Call a supplier in your area
Water suppliers usually operate locally. Ask for drinking water quality (agua potable) or non-potable water, because not every supplier delivers both.
Clarify quantity and access
A full tanker truck needs a driveable access road. On narrow finca tracks, smaller vehicles with 5,000 to 6,000 liters come instead, and the price per liter goes up.
Delivery date and payment
In dry summers, waiting times of several days are normal. Payment is often in cash or by bank transfer directly to the driver or the company.
Prices vary widely by region and distance. As a guide for 2026:
| Posten | Kosten | Dauer |
|---|---|---|
| Tanker truck 10,000 to 12,000 liters | 90 to 180 € | per delivery |
| Small vehicle 5,000 to 6,000 liters | 70 to 120 € | per delivery |
| Complete fill of an 8 x 4 m pool (approx. 45,000 l) | 400 to 700 € | one-time |
For comparison: from the mains, a cubic meter costs between 1.80 and 4.50 euros depending on the municipality. A complete fill by tanker truck is therefore considerably more expensive than from the tap, but in municipalities with a filling ban it is the only legal route. Our post on saving water on Mallorca shows how to save water and money in general.
Reduce evaporation and treat the water instead of replacing it
An uncovered pool loses up to 5 centimeters of water depth per week through evaporation at the height of summer. For an 8 x 4 meter pool, that is around 1,600 liters you have to top up every week. The most effective countermeasures:
- A pool cover (tarp or slats) cuts evaporation by up to 90 percent and keeps the water cleaner.
- Keep the water temperature low: the warmer the water, the higher the evaporation.
- Wind protection from hedges or walls reduces the loss further.
- Fill only to the middle of the skimmer, not up to the edge.
The second big lever: treat the water instead of replacing it. With good care, a complete water change is only necessary every four to six years. With regular filter run times, clean chlorine and pH values, and an annual deep clean, the water lasts many seasons. We break down what care and service cost in the post on pool costs and pool service on Mallorca.
Tip: top up in the morning hours
If topping up is allowed, do it early in the morning. That is when evaporation is lowest and the pressure in the mains is most stable. A sub-meter on the garden connection also shows you exactly how much water actually goes into the pool.
Conclusion
Whether you may fill your pool on Mallorca in 2026 is decided not by the island but by your municipality. In Prealerta zones like Deià and Esporles, tough restrictions apply with fines of up to 2,500 euros; elsewhere filling remains allowed. First check your town hall's Bando and the official drought index, plan for a tanker truck delivery at 90 to 180 euros per trip where bans apply, and reduce evaporation with a cover. That way the pool stays usable without you getting into hot water legally or financially.
