At a regional level, the regional administration has lifted the general prohibitions that were in place in the past. However, Spanish regulations stipulate that direct competencies over domestic supply and the use of drinking water in urban environments belong to the town halls. Therefore, if we own a property in Andalusia with a private swimming pool, we must specifically check the municipal decrees and local ordinances of our town or city in case there are specific limitations in specially regulated areas.
What Are the Mandatory Technical Requirements for Pools in Andalusia?
Although filling is authorized on a general basis, any swimming pool in Andalusian territory must strictly comply with a series of technical conditions to guarantee environmental sustainability:
- Recirculation systems: It is mandatory for the facility to have an active water treatment and recirculation system, designed to minimize the need to renew the total volume of the pool shell.
- Prohibition of emptying: Unjustified annual emptying is restricted unless structural repair or deep sanitary disinfection reasons are alleged.
- Local sanctions: The improper use of drinking water or refilling while bypassing local decrees can lead to municipal fines ranging between €30 and €1,800.
How Has the Situation of Andalusian Reservoirs Evolved After the Drought?
The technical reports presented by the Drought Management Commissions confirm that the autonomous community’s water reserves are well above alert thresholds. From recording absolute historical minimums in October 2024 (where Málaga’s reserves plunged to 15.5%), the situation has shifted to a scenario of absolute tranquility thanks to a winter of continuous storms and rain fronts at the start of this year, 2026.
Systems that were on the verge of collapse, such as the La Viñuela reservoir in the Axarquía, have far exceeded the normality limits set in the Special Drought Plan. This express recovery has even allowed the resumption of resource transfers that had been suspended for five years, guaranteeing the supply for both the tourism and agricultural sectors.

How Can I Optimize Water Savings in My Private Pool?
The main recommendation from professionals is to avoid emptying the pool annually and to opt for continuous chemical maintenance throughout the year. Keeping the same water in the pool shell for a period of 4 to 6 years is perfectly viable if correct disinfection and filtration guidelines are followed.
