What could possibly be better than swimming in your own inground pool? Swimming in one that is chemical free, low maintenance, and also provides visual interest year-round. Often called natural swimming pools in us these marvels in pool landscaping offer a sustainable alternative to the traditional gunite inground pool.
The Association for Swimming Pools and Natural Swimming Pools (ASPNSP) defines a NSP as one with the following attributes:
The NSP water is held in a vessel such that it is isolated from ground water and surface runoff water.
The swimming area or zone is physically separated from the regeneration area to protect the plants. The regeneration zone is also called a water garden as plants are typically planted in here.
Cleaning is achieved entirely through natural biological processes without chemical additives or devices.
The swimming zone gives homeowners peace of mind as it meets the strict standards of the Association of Pool and Spa Professionals (APSP) in terms of safety.
The pools are based on the principles of natural biological cycles involving beneficial microbes and bacteria. These processes convert detritus (waste matter) and impurities into food sources (nitrates) that in turn provide nourishment for the plants. NSPs have increased in popularity and are designed in any size and shape desired from a standard traditional-style swimming pool to that of an outdoor pond complete with a towering Oak and rope swing.
Natural swimming pools consist of two areas or zones called the regeneration and swimming zone:
Regeneration– The regeneration zone or wetlands zone is the heart of a natural swimming pool and is made up of shallow, deep water and marginal zones. Each zone is planted with aquatic plants native to that geographical area. The plants serve to filter and remove excess nutrients from the water. This zone resembles a water garden due to the variety of plants – floating, marginal and submerged.
Swimming– The water in the swimming zone is pumped through the regeneration zone to be clarified by the biological process. Specialized skimmers are used to remove leaves and large debris on the water's surface. UV lights and sand filters may also be used to remove phosphorus.
Imagine having a low maintenance swimming pool that is safe for people and good for the earth. One that sustains wildlife and is beautiful year round. Natural swimming pools or NSPs are free of chemicals, and ecologically and environmentally friendly.
