Have you booked a holiday to the Costa del Sol this year in either private rental appartments or airb&b or booking.com etc ? There is a huge water shortage here and pools will not be opened in residential complexes only in hotels and designated holiday apartments. I have noticed that many of the agents or owners are not giving this information out to people. Families are arriving expecting to be able to use the pool and are not able to. On top of this the beach showers and toilets are also out of use making that not a great option either.
I would suggest you check with who you are renting from to see if this is the case. They are using the excuse that the decision has not yet been made. I have just spoken to a very upset family who have arrived with the intention of using the pool most days.
There are also water restrictions and the water is turned off in some residential properties overnight meaning people are filling buckets to flush the toilets.
Please if you have spent a significant amount of money check that you will have access to the pool !
