How come we are being bombarded with adds to save water all of a sudden?
Perhaps it’s because there is a shortage due to so many data centres being constructed.
Or perhaps the amount of water the fashion industry uses.
Or is it the fact that there are millions of new houses being built across the country.
And if it is the same as round here it must be more than millions.
I remember in the mid 1970s We were advised to share our baths/showers to save water…and if My memory serves Me right,My Husband and I saved a LOT of water that Year 
Goodness you’ve surprised me there.
I was going to say it’s all because of the recent heatwave and dry summer and the worry over a forthcoming low rainfall winter but I see what you mean about the fashion industry though I would never have believed it.
Amazingly …
AI tells me …
Textiles: Making a single pair of jeans takes about 7,600 litres of water.
But also …
Automotive: Manufacturing an average car requires roughly 148,000 to 175,000 liters of water for painting, surface treatment, and cooling.
Food & Beverage
Producing a single liter of soda can require 350 liters of water.
I thought most of the clothes in the shops are made outside the UK, so it seems unlikely that this is the cause of the fears of water shortages.
Perhaps its the droughts in some parts of the country - and after drought any rain simply runs off the hardened land. Plus its quite hard to move large volumes of water from up north to down south.
Perhaps its decades of under-investment in the water infrastructure by the private water companies. So leaks, insufficient reservoirs, etc.
Perhaps its individual water consumption - it seems Denmark people use 40% less water each than in the UK. Apparently placing a brick in your cistern helps, or shorter time in showers. But then their water is significantly more expensive…
Perhaps its the need (not my word but apparently its a need) to build huge data centres for AI. Or to irrigate golf courses. All of which is done with the highest quality drinking water…
