Major Water Crisis - Some areas Costa Del Sol Malaga running out of water. Fuengirola just a drip

Seriously.  There is a major water crisis and your worried about your shower. Ask the mayor's to have a word with God and get him to turn the rain back on. 

Great answer 

which God?

Which ever one you want.  

Some people are unbelievable.  

The only long term solution is to change to an electric heater. The changes to climate tend to suggest water shortages in this part of Spain will not go away and one obvious method to save water is to reduce pressure.

This article explains some of the pending problems but does not really tackle the forthcoming problem which will probably become more severe during the tourist season in 2024...  https://ppandalucia.es/en/andalucia/sequia/.   There are other measures in place to alleviate the issues...

"Work to double the capacity of the desalination plant in Marbella will end in the first half of 2024. Then it will be able to provide a better service during the summer seasons with a maximum influx of tourists.

The date was confirmed by the regional minister for Agriculture, Fisheries, Water and Rural Development, Carmen Crespo, during a visit to the plant, managed by public water company Acosol.

The expansion, included in the third drought decree of the Andalusian regional government, will increase the amount treated to 12 cubic hectometres compared to the current six."

"The only long term solution is to change to an electric heater"

Not sure why you posted that reply, how will an electric heater help? It's also depended on water pressure. However, in future people without water storage tanks, will be the worse effected. Even then they need sufficient height or also need an electric pump.     

Electric heaters do not require a minimum flow in the way that gas heaters do (for safety reasons). Granted, you may only have a low pressure shower but the water will be hot.

"Electric heaters do not require a minimum flow" 

You only get out the pressure which goes in, recently there was not enough pressure for the electric water heaters to work at all, which is where this thread started. (The person had no water and frustrated could not take a shower) Many did not have storage tanks on the roof and they were the most effected by the water shortage.
