Natural swimming pools (NSPs) are an increasingly popular ecologically-friendly freshwater alternative to conventional chlorinated and salt-water pools. 

Conventional pools rely on chlorine and other chemicals to maintain sterile, algae-free water. NSP’s, on the other hand, are anything but sterile. They are uniquely beautiful living aquatic ecosystems, designed to look and function like a natural pond. Water quality is maintained through the combination of bio-filters, UV filters, and mechanical aeration in combination with lush aquatic plant filters—the signature feature—surrounding an open swim zone. The plant filters, in turn, provide a habitat for birds, dragonflies, frogs, turtles, newts, and a host of other fauna. The resulting freshwater swimming experience is unparalleled in the industry.
