Met a guy who is installing a natural pool. Here is a wiki definition

A natural swimming pool or natural swimming pond (NSP) is a system consisting of a constructed body of water, where the water is contained by an isolating membrane or membranes, in which no chemicals or devices that disinfect or sterilize water are used, and all clarifying and purifying of the water is achieved through biological filters and plants rooted hydroponically in the system.


So there is a hole in the ground with a membrane laid at the bottom and extending over the side for a few feet. He wants the overhang as long as possible. There is no overflow other than when it rains it pours over the top and then onto this membrane. Water is pulled from the bottom of the pool where the plants are located. The water is injected back into the pool about 2' down in the deep end where the swimming occurs.

No chlorine just a sand filter. He was trying to get by and not have any equipotential bonding. I told him, IMO he had to but the equipotential bonding was going to be under the rubber membrane.

So you see where this is going-- how effective do you think the equipotential bonding will be if there is a rubber membrane sitting atop the soil. I told him he still had to have it since, IMO it is a pool as well as a artificial body of water or is it? How does this differ from a pond or lake?

Just thought it was an interesting situation and wondered what you all thought. This is not exactly what it will be but the idea is there.

I thought it was beautiful but not sure how practical as a pool. My concern was how to wire things----Is art. 680 being used here

If there is a light , or a pump , you would have to . I think you would have to ground and bond according to the NEC regardless .

You would still need to provide a Recpt with in so many feet of the swimming pool right ?

Yes bonding but where- remember the pool I am talking of does not have the overflow like the one shown unless there is a heavy rain

No I haven't. I am not doing this job and I am not sure how orange county sees it but I think they see it as a pool. The question is more the equipotential bonding.

This pic is more like it but instead of the deck there will be just that membrane coming over the edge of the pool.
