Water Restrictions and Pools on Mallorca: What Owners Can and Cannot Do in 2026

Mallorca has one of the densest concentrations of private pools in Europe and a water balance that swings hard between wet winters and dry summers. In recent dry years several municipalities have limited or banned filling private pools with mains water during the worst months. Here is what that means in practice for owners in 2026, and how to run a pool that restrictions barely touch.

What restrictions usually mean

Rules are set municipality by municipality and change with reservoir levels, which is why your neighbour two towns over may face different rules than you. The common pattern in dry summers: no filling or refilling from the mains while the restriction lasts, with exceptions varying locally. Filling by water tanker normally remains possible, at roughly 100 to 150 EUR for a standard 8×4 pool load, and your town hall or your pool company can confirm what applies in your municipality right now.

Evaporation is the silent thief

An uncovered pool on Mallorca can lose up to five centimetres of water a week in high summer, which over a season adds up to a large share of the pool volume. A cover is the single biggest lever an owner controls: it cuts evaporation dramatically, keeps heat in and chemistry stable, and pays for itself in water and chemicals alone.

A leaking shell wastes water twice

Old grout, hairline cracks and tired skimmer joints let thousands of litres migrate quietly into the ground, and under restrictions that loss is doubly expensive because replacing the water may not even be allowed. The 48 hour bucket test tells you if you are losing more than evaporation, and professional leak detection finds the exact spot without digging. A full renovation with a watertight shell runs 8,000 to 20,000 EUR and turns a thirsty pool into a tight one.

Maintain year round instead of empty and refill

The old habit of emptying the pool each winter and refilling in spring belongs to a wetter era. Modern practice on the island is to keep water in the pool year round, balance it through the winter and avoid the 48,000 litre refill entirely. A service contract at 150 to 250 EUR per month costs less than most owners expect once the saved water, chemicals and spring repairs are counted.

The checklist for a restriction proof pool

• Cover on whenever the pool is not in use
• Bucket test once a season, and after any suspicion
• Backwash the filter on schedule rather than by habit, every backwash sends hundreds of litres to the drain
• Fix leaks the same season they appear
• Keep the water in the pool over winter, maintained rather than replaced

Restrictions are not going away, but a tight, covered, well maintained pool sails through them. If your pool loses water or the shell is due for renovation, request free quotes from vetted local builders and fix it before the next dry summer.
