7. Conclusion

This article provides an overview of the various drinking water treatment techniques used to supplement the drinking water distribution infrastructure, in order to alleviate certain troublesome aspects of the distributed water (taste, hardness, etc.), for use in private swimming pools or for heating water.

Never "tinker" with appliances. Water is too sensitive a product to be treated carelessly. Investment and maintenance costs per cubic metre of water treated are inversely proportional to its capacity. It is therefore preferable to treat the water of a building, or a housing estate, rather than leaving each family responsible for its own treatment.
