Tap water in Málaga
By Linus Palmqvist, Head of Operations Reviewed by Simon Nilsson Last reviewed Yes, and it is softer than almost everyone tells you. Málaga's water company puts the raw supply through reverse osmosis, and says the water reaching homes is habitually below 110 mg/L of calcium carbonate. The Costa del Sol's reputation for scale-heavy water does not match what its own operator publishes.
Málaga's tap water meets Spain's national drinking water standards and is monitored by EMASA, the regional health authority and the national database. What makes Málaga unusual is the treatment: since 2006 the raw water, which arrives brackish, has been put through reverse osmosis at the El Atabal plant, and that strips out a great deal of the mineral content before it reaches you.
EMASA supplies the city of Málaga. Other Costa del Sol towns have their own arrangements, and Marbella and the western coast are served by Hidralia under a separate municipal contract, so nothing on this page should be assumed to apply to a property in Marbella, Mijas or Estepona.
EMASA publishes the analysis of the water leaving its treatment plant, and the national database holds the results for your supply zone. Between them you get a much better answer than any figure quoted in an article.
EMASA water quality analysisIt reports the quality of the water leaving the El Atabal treatment works, which is where the reverse osmosis happens.
SINAC shows whether your supply zone is currently classified as suitable for consumption, when it was last sampled, and anything outside the permitted range.
Treated water leaving a plant soft does not stay that way if it sits in a neglected roof tank. Older blocks and long-empty holiday flats are worth a closer look than the municipal average.
EMASA runs water and sanitation for the city of Málaga. As everywhere in Spain, you do not choose it and you cannot switch away from it. If your property is outside the city, check your last bill: the western Costa del Sol is served by Hidralia under a different arrangement.

No English service publishedWe could not verify any official English service at EMASA. Its customer channels run in Spanish, and we found no published commitment that a phone call or an office appointment will be handled in English. Given how many English speakers live along this coast that is a little surprising, but it is the normal Spanish position and Barcelona is the exception.
Change the bill into your nameWe checked the major water companies across Spain and marked which ones actually deal with customers in English. See every city in the table .
Ask around and you will be told the water here wrecks appliances. The operator's own figures say otherwise, and the reason is a piece of infrastructure most people have never heard of.
EMASA says the water it supplies is habitually below 110 mg/L of calcium carbonate, around 100 mg/L, and classifies it as semi-soft. That is a long way from the scale-heavy water Málaga is often assumed to have, and it is worth knowing before you spend money on a softener you may not need.
The raw water reaching Málaga is brackish, so it is treated by reverse osmosis at the El Atabal plant before distribution. That process removes a large share of the dissolved minerals, which is what brings the hardness down. Most Spanish cities do not do this to their whole supply.
Two things. The wider Costa del Sol is not all supplied by EMASA, and other towns along the coast draw on different sources. And a lot of the pages telling you Spanish coastal water is hard are published by companies selling water softeners, which is worth remembering when you read them.
Get the last water bill from the landlord, seller or agent and photograph the meter with the reading visible on the day you take over. Then get the contract moved into your name. EMASA handles this through its virtual office and app, and the process runs in Spanish.
We contact your local water company and get the bill moved into your name, in English.
Still have questions?
Free, in English, whether the water is running and the contract just needs your name on it or the supply has been switched off and needs reactivating. Useful in Málaga, because EMASA does not publish an English service.

Head of Operations at Settlewell
Linus moved from Sweden to Málaga in 2021 and set his own home up here, so most of this he has already done the hard way once. Before Settlewell he spent years at Workwide, the cross-border recruiter that has helped over 10,000 people into jobs abroad, latterly as its Head of Recruitment and Operations. He speaks Spanish, lives in Málaga with his partner, and spends his days on the phone to Spanish providers.
