hi guys
i am desiging a swimmig pool
and for the pool i want to make it as sustainable as possible, i was once introduced to the idea, of placing a pool under a pool, which will bbe used to help clean the water out and then can be pumped back up to the pool.
so the pool below the pool will be used to drain the pool water into to clean and then sent back up, so water can be re-used, recyled. does anyone know about this>? i am thinking more commercial rather then domestic?
i will be so grateful for some advice on this as well as other ideas for sustainable pools.
(this is my first post)
Thank you for listening
