Underwater CCTV

[Popolou]

Does anyone have any experience with or could recommend a CCTV ip cam that works at some pretty serious depths? Got a water well that is pushing circa 150m with a suspected collapsed pipe. Managed to rig up a standard CCTV POE camera down to 65m before hitting a 15m column of water at which point it imploded. Or is this approaching specialist territory?

Cheers

That sounds a bit specialist, and surely you're going to have to get someone who knows what they're doing to fix it who'll probably have the right gear anyway?

[Popolou]

Apparently not, and their suggestion is to push the existing pump to let it fall to the bottom and replace but if there is any pipe in there it will kill the well. Too expensive to do it blind and hope for the best unfortunately.

Speak to a drainage survey company, or hire the type of kit they use.

Good suggestion, seems their fibreoptic kit can go +150m which is key but no idea on pressures and depths. Will give a few a call. Cheers.

Thing is if you're looking at maybe >80 metres of water the pressure is going to be pretty serious - 8bar plus - more than most drain inspection cameras or standard dive cameras would take. You're into secondary dive camera housings and that's getting expensive. Plus none of them are tethered IP cameras anyway.

If you really want an IP camera you could get a cheap one and encapsulate the whole thing in resin or a waterclear silicone. And seal the cable too.

Plus some decent lighting to go with it.

Cheers, yes that also came up in discussions and exploring that too. Found a few in the 2-300 quid mark which seem to be the right dimensions for a cheap IP cam. And this is all assuming i won't need more than the 100m IP will works to. More i think about it the more that i feel this is going to lead me to a specialist outfit with the right kit.

Out of interest, if the water level is hit at 50m (65m less 15m), why do you need to go down to 150m? Does the level vary significantly throughout the seasons?

150m is pretty deep, definitely into specialist kit. But having had some borehole experience, I doubt it will be cheap.

Sorry for the delay, yes the borehole is 150m deep and the water course/level is at 65m down. The original problem was a failed pump that we couldn't extract. So it's likely after a lot of faffing around it eventually fell to the bottom (150m down) and pulled some of the remaining pipe with it. But we need to be sure before installing all anew. Trouble is, they don't normally go that far down anymore so i am struggling to find anyone with the right kit.

Already looking at a £4k bill so yup, it's piling up!

Surely a drain survey company or a bore hole drilling company would be best. And if they didn't have the right kit then they would be able to put you in touch with someone who does. It's deep, but it's not that deep, I'd be surprised if a fibre optic CCTV wasn't good for 100m of water.

If you have a go pro, or can borrow one, you can get houses which are safe down to 250m, for under £300. Okay it's not a live feed, but would surely do for what you need?

Yeah - seems to me like one of those endoscope cameras typically used for drain inspections wouldn't be bothered by depth .. so long as the fibre optic cable was long enough. Borehole drilling companies are bound to have them, probably the drain ones don't have the length but you never know, gotta be worth explaining to a drain cleaning operation and seeing what they say.
