Young Reddish Blonde Girl Enjoys The Swimming Pool

Natural pools and ponds
Natural pools were developed in central and western Europe in the early and mid 1980's by designers and landscape architects with environmental concerns. They have recently been growing in popularity as an alternative to traditional swimming pools. NSPs are constructed bodies of water in which no chemicals or devices that disinfect or sterilize water are used, and all the cleaning of the pool is achieved purely with the motion of the water through biological filters and plants rooted hydroponically in the system. In essence, NSPs seek to recreate swimming holes and swimmable lakes, the environment where people feel safe swimming in a non-polluted, healthy, and ecologically balanced body of water.
Water in NSPs, being 100% chemical free, has many desirable characteristics. For example, red eyes, dried-out skin and hair, and bleached bathing suits associated with overly chlorinated water are naturally absent in NSPs. NSPs, by requiring a water garden to be a part of the system, offer different aesthetic options and can support amphibious wild life such as snails, frogs, and salamanders.
