How to avoid drinking water shortages

Artificial recharge to ensure the sustainability of groundwater

While in many countries access to clean water is still arduous, this is not the case in places like France. At least, that was true until the late twentieth century. However, climate change is changing things. Indeed, some French water tables are providing less water , this in relation to the amount of precipitation received during the winter, among other things.

As a result, as this report from Le Monde shows, some places are trying to artificially recharge the water tables in order to maintain their sustainability. For example, at the Pecq site, water is pumped from the Seine and piped into various facilities to filter it of its waste. It then seeps into the ground, and this to the aquifer environment. The water can be drawn and purified again for human consumption. A practical alternative, but unfortunately not applicable everywhere.
