First you take a layer of gravel to reduce the insoluble contaminations.
The second layer needs to be finely grained sand. The silica will get rid of the manganese, iron and other metal contaminants.
The third layer is zeolite rock which exchanges harmful for benign ions.
Lastly you need a strong carbon like charcoal that reduces the impurities even further.
You boil or distill the output to kill off the microorganisms.
And then you drink the water through a filter made of thin coconut husk films.
What you drink will not be water anymore at that point, it will be a mineral-filled cocktail of a higher dimensional order. There exists nothing in this life that will give you a higher sensation of satisfaction, nothing more worthy to be called by the 4 letters that embody a transductional principle known as love.
