I'm from the Netherlands. The last few years there have been issues with ground water levels dropping and a lack of rainfall. To the point where water companies are asking consumers to reduce their water use for e.g. irrigating their gardens, shower less long, etc.

Of course, the notion of a water shortage in a country where two of the largest rivers in Europe empty in the North Sea and that keeps about a third of it's land that lies below sea levels dry by actively pumping relatively clean water out is a bit of a weird notion to sell. We have a surplus of water, not a shortage. Rivers overflowing their dikes is an issue we deal with regularly. And a lot of infrastructure to dump that into the North Sea by the millions of liters per day.

The issue isn't that there isn't more clean water than we can handle but that more water gets taken from limited ground water reserves than is added back naturally. This would be a non-issue if we'd mostly use surface water instead.

Most of this ground water isn't even used by consumers but by agriculture. And worse, farmers also work very hard to keep their land dry after irrigating it because they need the ground to be moist, not soaking wet as in a swamp. The water that they drain is very high in nutrients because they are using a lot of fertilizer too. So, basically, agriculture is in the business of taking rain water that dumps on their land and surrounding lands and basically dumping it into rivers without even using it for irrigation. But then when it doesn't rain, they use ground water to irrigate, which then drains into rivers. As a result, nature is suffering because ground water levels are dropping and because surface water is polluted. Ground water is also used for consumers.

The solution is of course to use slightly more expensive to use water from e.g. surface water or rain water (which is generally drained to get rid of it ASAP). Of course a lot of that water isn't as easy to access everywhere so it requires infrastructure (pipes) or storage (reservoirs). But historically, ground water was there and relatively clean (so it can be used without much processing) and people just use it without thinking about it. Most people with gardens don't even capture the water that falls on their roofs, which on an annual basis should be plenty to water their gardens. Neither are they (re)using grey water or rain water for e.g. flushing their toilets. All of that is done using tap water that comes from ground water.

This isn't a shortage crisis but a water abuse crisis. The solution is being a bit smarter about what water we use for which purpose. And a lot of that is rethinking intensive agriculture. We grow crops to feed cattle that produces so much manure that we have severe nitrogen pollution getting in the way of economic growth because we have to limit construction in/near polluted areas. Those crops uses ground water and feed the cattle. The problems are connected.
