Natural Swimming Pools, also known as Natural Swimming Ponds or NSP’s began in Europe over 40 years ago. As the demand for environmentally sustainable options grow, so does the audience wanting an environmentally friendly swimming option. In the USA, BioNova has become the preeminent name for expertise in NSP’s. Coupled with over 50 years of experience in the traditional chemical pool industry, BioNova USA knows how to design NSP's that use the proven European techniques and technologies. NSP’s that meet the European Standards DO NOT use any chemicals (like chlorine, bromine or biguanide) or devices (like ozone, ionizers, or salt systems). Ecologically minded swimmers love bathing in a natural pool that is completely free of chemicals. The proven designs that we use have been effective for years in installations throughout the world. Some NSPs (BioSwimPonds) have the "look" of a pond, with aquatic plants contributing to the filtration and aesthetics... Other NSPs (BioPools) do not require plants, but instead mimic the biome of a river or stream using biofilm filtration.
