    Or just build more water reservoirs

    Crimea is an arid region but anyway you can not have a city like Sevastopol depend on just rain water.

    No, but you can make sure rain water is collected and used and that water is not wasted.

    Putin already said that desalination is expensive and will affect negatively water bills of the citizens in Crimea.

    It would be unreasonable to expect others to pay for it.

    Here in New Zealand most places water is not a problem because we are not in an arid region, but places like Auckland which has 2 million people struggles with water supply... they take water from the nearby Waikato river, but there are water charges... water going in to a house and water coming out of the drains and sewers is charged... so rain off your roof goes on the garden or is stored in large tanks for use for cleaning or baths, you might use a water purifier for drinking water.

    Charging for the use of water will immediately stop a lot of people wasting water, and those that continue can pay for it.

    Water charges can pay for any water system needed, as long as the money does not get diverted elsewhere.

    Sad part is both tourism and agriculture which are region´s main economic activities will be hugely affected by this water shortages.

    Both of which are industries that can pay for water schemes to get the problems sorted.

    I doubt one solution would work... a few different solutions would be better...

    Only solution is opening of the NCC but I dont see this feasable.

    Well perhaps telling Kiev if the NCC does not start supplying water to Crimea any time soon then the renewal of the gas contracts for gas transit through the Ukraine will be reconsidered.

    I would continue with alternatives too and if the NCC is reopened would carefully check for impurities and contamination.

    Is it not possible to build a pipeline attached directly to either one of the Kerch bridges? Maybe underneath or to the sides via an overhang.

    If the Banderites start any stupid shit with either Donbass or Crimea I think it would not be surprising if the Russian military elects to test an Iskander or three on the peninsula, and the improvised dam on the NCC might suddenly come apart at the seams as a consequence.  What a shame that would be.  Oh the horror...  Twisted Evil

    Apparently there is no water to spare on the other side of the bridge.

    That is not a serious constraint. Russia can build a water pipeline that can tap the necessary sources. But that requires money.

    Doesn't the Kuban river drain into the Azov just a few km east of the Kerch strait? That should be plenty freshwater enough for one huge pipeline.

    Apparently Russia has closed the Kerch strait for a week and left Mariupol and Berdyansk cut off... not necessarily related to Ukraine closing the water supply to Crimea, but a good example of the measures that can be taken to teach the Nazis some manners...

    Not sure, just reporting what I had read.

    I read there are large freshwater aqufiers below the sea of Azov and Russia is drilling wells. The sea itself has very low salinity.

    Only viable long term solution is building couple of desalination plants, for which additional energy sources will be needed plus new technology, all this of course will be very expensive. It will take years if not decades before water crisis will be solved realistically.

    I don't think they need to:

    https://112.international/conflict-in-eastern-ukraine/occupation-authorities-plan-to-get-fresh-water-in-crimea-from-water-well-holes-azov-sea-59869.html

    in any case desalination by reverse osmosis should be quite efficient as the sea of azov is about 1/3 the salinity of typical sea water.

    It is a growing region... an extra nuclear power station would probably be useful anyway going forward... a floating power station could be a short term solution too, but I suspect no one solution will solve the problems... the application of several solutions would be best... having excess electrical power and water supplies will allow more expansion and growth and is going to pay for itself quickly enough.

    Just like improved access via the new bridge and rail links have improved access and made it an easier to get to destination.

    Didn't they already run power cables to Crimea? *Edit* actually they ran 4 lines to Crimea.

    Ukraine responds to data on the discovery by Russian scientists under the Sea of ​​Azov of fresh water that can solve the water problem of Crimea

    Drilling preparation: Crimea will be provided with water from under the Sea of ​​Azov

    The Crimean peninsula has become even closer to solving the "water problem". According to the Deputy Prime Minister of the Russian Federation Marat Khusnullin, wells for the extraction of fresh water for the residents of Crimea will be drilled under the Sea of ​​Azov.

    Khusnullin informed that well drilling will begin in July, and preparatory work is currently underway. Now research in the region for finding fresh water deposits under the Sea of ​​Azov is conducted by two scientific vessels. Scientists must determine the volume of a possible underwater basin, as well as the likelihood of using these waters for domestic needs.

    We are exploring at full speed, we drilled on the spit, we found water, industrial water can definitely be - stressed the Deputy Prime Minister of the Russian Federation, quoted by TASS

    In recent years, the Crimean peninsula has suffered from water shortages caused by droughts. The reserves from under the Sea of ​​Azov will be able, according to the assumptions of experts, to become another source of water that is so necessary for the Crimeans. Deputy Prime Minister of Crimea Yevgeny Kabanov said that scientific research in the region is being conducted by one of the leading profile Russian companies.

    In September last year, it was announced that the construction of the first Russian seawater desalination plant in Crimea was started. In December, Marat Khusnullin noted that desalination should be the last resort for providing residents with fresh water, and attention should be paid to other sources.

    Interesting, over time that should make the Sea of Azov deeper as the evacuation of the aquifer results in subsidence of the rock strata.
    Maybe not that much deeper, but not zero for sure.

    But would there be subsidence, or would drawing fresher water from underground allow more salt water from higher up to filter down... presumably that is how the water got there in the first place and in getting there was filtered and lost much of its salt.

    If it was salt water seeping from above it would never have become fresh. In this case the aquifer is a layer of porous "rock" that extends horizontally onto the mainland
    where it gets the fresh water injection. It really is isolated from the salt water above.

    There are other types of water bearing ground layers where a thick layer of clay acts like a barrier. I am not fully informed on the geology of the Sea of Azov. The "rock"
    may be 10,000 years old and formed from different types of silt deposits in this sea (which is just a bay of the Black Sea). But these deposits include enough fine grades
    that have started to turn into different types of shale.

    http://www.ssc-ras.ru/files/files/11_QI_2013.pdf

    The Sea of Azov has been backfilled with silt and clay deposits thanks to river transport for a very long time. This for sure has resulted in shale-like strata
    that are good at trapping natural gas or oil. They do a good job of trapping water as well. Silt and clay are not the only type of deposits and there are
    sand layers as well which give rise to sandstone. I think that at the relatively shallow depths that there are few gas and oil deposits but kerogen deposits
    instead which have not experienced the slow compression "cooking" into gas and oil. But the various layers of more and less porous rock precursors (both
    shale and sandstone) are there which can trap fresh water.
