Quite a lot, even if it is a long term project. UNICEF reports that, "Between 2000 and 2022, 2.1 billion people gained access to safely managed drinking water and the number of people lacking at least basic drinking water services decreased from 1.2 billion to 703 million.” [O] That’s not everyone but in about 20 years 2 billion more people got access to safely managed drinking water, and the amount of people who lacked basic drinking water dropped by half a billion in the same time. It won’t mean much to the 700 million who don’t have safe drinking water but progress is being made. 0: https://data.unicef.org/resources/jmp-report-2023/ https://data.unicef.org/resources/jmp-report-2023/
