Is there really such thing as a “green” swimming pool? I’ve been wondering this for about a decade now. We had planned to build a natural swimming pool(NSP) on our property as soon as our kids could safely swim – and that day has finally come. We are now in the planning phase and hope to start construction in early spring if all goes well. There are many types of natural swimming pools and they can be the same style and materials as a conventional swimming pool or look like a natural pond. So what is a “natural swimming pool”? It has two main components:
the swimming zone – can be made with pond liner or even a gunnite concrete material with tile like a conventional pool.
a regeneration zone – where plants rooted in gravel substrates consume the excess nutrients. This area can be within the pool behind a separation wall, or in a separate vessel altogether.
