Being Australia, I'm sure there is some old grand ma who has written some regulation about pool depth but I can't find it.

I want to build a pool that is 4m wide x 20m long and at it's max depth 5m, but I only need a small section to be 5m deep.
No gradient, just a straight drop off from 1.5m to 3m then 5m.
Can it be done?

I can't be the only one that's curious about why you want to do this. Are you plannning on having a 3m diving board, or do you just want to take playing Marco Polo to a whole new level?

I like sitting/lying at the bottom of deep pools, the pressure makes me feel better. I can free dive ~25m.
I would love 30m deep but I doubt that's possible or would be prohibitively expensive.

Hot sauna + cold 30m deep pool = bliss.

I got short of breath just watching that

What is it for?

Called a NSW pool builder... he said he's not aware of any depth constraints but it would exponentially increase the cost... North of $250k for a basic design to 3m depth.

Get a dam builder in and go to 20 metres.

It will make it cold. will take a lot longer to heat up come summer. U really want that? Mates dad likes cold pools so he made his deep. it was fkn freezing.

would the depth need to take into account distance from near by structures?, I think it relates to shear failure.. and the capacity to not affect the stability of soil surrounding structures during your dig phase?

Yes definitely and the type of soil but you can always underpin the nearby structure's foundations or use piles and capping beams to overcome that as long as you you have the desire and $$$

theres a pool at the top floor of a cairns apartment building. Prvatley owned. Sticks out several meters from the outside of the building with a glass floor and sides. So you are swimming 12 stories up with nothing below you. Would be great for skinny dipping with nude members of the opposite sex i reckon. Apparantly the whole apartment is soundproofed for the loud parties. Just goes to show you can do anything if you have the coin.

You would get a nice diving boat for that and the maintenance would probably be the same cost as a pool that size.

Thats a friggin' big pool

That sounds familiar. Yep, near the hospital there, I knew I'd seen that before...

thats the one. chemist wharehouse or maybe terry white? one of the chemist chains.

Did you slip that zero in by accident? I was quoted $25k recently.

Edit: actually, I've just re-read your first post and given the length you're talking maybe that's right, although it's still a bit steep for what's basically a sealed hole in the ground.

You could possibly drill a well, say 1-meter diameter.
I have something like that on farm, about 15 meters deep, square 2 x 2 meters

the movie is about 2'.15 "long. But the guy needs to resurface. So more like 3 and half minutes. not many can do so even sitting in the chair by a computer screen.

I think must be some gold deposited at the bottom after few hundreds/thousands of years, but how to get to the bottom to check it out?

Build up instead of down, or split the difference.
