They're not just for the Beverly Hillbillies...For a more natural swimming experience consider a natural pool that is completely chemical free with a self sustaining ecosystem. These cement ponds have a swimming zone for recreational bathing and a regeneration zone for cleaning the water, think marsh plants/water gardens.
Europeans have been using these kinds of pools for over 20 years successfully and they are now in the United States, check them out here.
So if you are tired of the chemicals and like that more natural look, you too may want to consider a cement pond.
