Terrible idea, what kind of fool would do this?
Looking good.
Filtering water to purify it should be as simple as sand, charcoal and gravel, though I'm not sure what the proportions need to be to ensure filtration of all micro-organisms. Boiling under about 15psi of pressure will kill anything that gets past the filtration. Viruses are another matter though, not sure how to eliminate 99.99% of those. There is always distillation, but distillation removes the flavor that people expect in their water. I suppose trace minerals could be added back in, even fortifying additives like calcium and fluoride to protect pony teeth could be added.
Stainless steel, not only difficult to make, but difficult to make safely as it requires chromium, and that is some serious toxic death.

Cave divers, spelunkers, deepsea divers, you know, crazy people.
Terrible idea to leave the phone unattended
going against a current, with out propper equipment, posibly diving into a cave, hmmmmm, as a diving instructor i know there is little else that you can do wrong, maybe if he blinfolded himself and when they are halfway down strangle the pony??
Swimming into what I presume is an underground river?
Better bring some thread lest you get lost!
9388561
Out of curiosity, what sort of equipment?
9388401
Don't forget wreck divers.
9388693
Them too.
Im wondering if the guy getting asked about the water pipe spell is only used to doing nobles houses, one or two supplies for bathroom, maybe kitchen, a small thing a unicorn can barely fit their horn inside, rather than the city pipe thats made out of cannon sections big enough to stick the whole unicorn inside.
Depends on how far their alchemy has come, the simplest way to make Pure Water would be to use a Solar Still with an Alembic. Given how short the cooling stem available is, a great advancement would be the water cooling jacket, coil, and reflux condenser. Which would mean souring pure sand, lime and other materials, such as the only place to use lead, as lead oxide, up to 40% by weight, resulting in a simple version of heat resistant glass? Borax, used in metallugical flux makes a resulting glass even tougher and more resiliant?
If there isnt rock farms already, then starting the crystal caverns growing hollow gems would lead to them? Drill a hole in the ground, rock, spell it for a given gem material, variation of the purification spell, then let impure water flow through it for material supply?
They have animal repulsion spells for other reasons that can be used around the pipe entrance to stop fish etc getting in to the main filter spell?

Too bad they don't have much choice at the moment. As long as they are nopony like Pinkie, Rainbow, or Lyra nearby, it should be fine.

They are not due to exist for some time. Coast is clear!

Filtering water to purify it should be as simple as asking any random pegasus to form a cloud and make it rain into a public fountain. Then once a day, drain the fountain dry and let the sun sanitize it. Waterborne pathogens aren't going to survive an hour of no moisture on dry stone at noon. Or enclose the fountains in glass, build a few simple pumps so that ponies can put water into containers instead of directly sticking their mouths in, and maybe only sanitize it once a week. Or once they have the magic purifying ring, just stick one in the pipe that pumps water from the fountain, and then you don't even need to drain or clean it anymore.
They could do all this right now with virtually no expense and without months or years of quarrying and masonry. And given the number of fatalities it would likely prevent over that time, it would be irresponsible for them to not do something so simple as this. Plus it would provide a proof of concept that would be likely to result in greater faith and funding from the princess.
The issue is that once you start exploring the question of "what makes sense in Equestria," does it really make sense to go ahead with that year-long city-wide megaproject to build a brick aqueduct? Wouldn't it be faster, easier and cheaper to simply add it to the duties of the weather patrol?
Tracking the source of the water into and up the mountain, to hopefully find a closer location to tap into? Good Idea.
Using a water breathing spell that requires a Unicorn maintain it with power and presumably concentration while navigating an unknown area? BAD IDEA! A sharp blow to the Unicorn's head and you both drown.
Swimming against the current into a cave system to find the water's source with ZERO training, preparation or equipment? TERRIBLE IDEA! Cave diving is incredibly dangerous. Even if you assume a virtually unlimited source of air from unicorn magic, getting lost/trapped and then dying of starvation are very real dangers. If you can't find your way back out, you die.
As far as equipment goes. If you're cave diving, aside from plenty of air, you're going to need light of some sort and a virtually foolproof method of navigating back to the entrance. A visually unbroken line of easy to see rope along with markings indicating "Entrance is back this way" would be a good start. Again, if you can't find your way back out, you die.

Especially in a recently transformed hybrid body that our protagonist has never used to swim with before.
“There are old divers and cave divers. But there are no old cave divers.” -Unknown

Put me in mind of the discovery of U-869. three divers lost their lives searching for evidence that would put a name to the unidentified sub they'd found. Two of them were father and son.

rebreathers, flashlights, a lifeline, anchors for said lifeline, a gas mixer, if they dive to deep, oxigen becomes toxic, and general saftey equipment, like special wetsuits, cold water will suck the life out of you faster than you might think, a computer or a way to measure the time spent underwater necesary to make a saftey stop, if you dive for more than 20 min and its more than 90 feet you need to make a saftey stop or else you can get decompresion sickness, or diving at 35 feet for more than 120 min, there is a lot of stuff you need to do safe diving, but in this case you might just say magic and problem solved
if you are interested in more info you can ceck PADI https://www.padi.com/ they have lots of info on diferent diving subjects

Long Live the memory of the crazy people for they are the ones who discover.

Well, I don't like to say 'a wizard did it', but they are diving with unicorn air magic, so I'm pretty willing to say breathing is the least of their problems.
There are soooo many other problems, mind, but breathing? They're good on that, to start. There are no gas thingies required, since they are not using breathers to get air. I blame unicorns.
Cold water, still a problem. How cold is it? Undetermined, which isn't good either. Will it get colder or warmer? We'll find... out?
Light, are they going to rely on unicorn mare to be that source too? Why's everything gotta rest on her shoulders?!
If this is a spring and not just a cave then they are gonna have a bad time. If the pond is fed by underground spring, they are basically dead if they get past the first branch. The water traveling in underground rivers can easily reach white rapid speeds or faster. Branches can form outlets that are low-flow due to only utilizing excess pressure in the system but once they reach the main thoroughfare, it will just sweep them away. Supporting this is a branch and not the primary outlet. Exploring underground springs is not a job for the living. That's something beyond even cave diving. This is legit, straight-up, lethal.
Yeah this sounds very risky, they should just hire a Seapony or something to figure out the source, that or get someone magically inclined to do so. I mean this is a pony society, no? You could literally go for a walk and then grab any random pony with swirly and watery mark and toss him or her at the problem and expect above average result no?

It's not about the gas it's about the pressure, the deeper you go, oxigen becomes toxic, in general, it's not really a tank thing, the pressure of the water makes it so, and the more pressure there is, nitrogen can make bubbles in the body wich causes decompression sickness If the pressure is reduced too quickly, however, the nitrogen comes out of solution and forms bubbles in the tissues and bloodstream.
9388976
Making rain clouds is an industrial process in the modern show. It's probably a lot harder to do by hoof.
It might be easier than hiring earth ponies to fill up a watertight wagon at the spring and haul it to each public fountain, but it might not.
No, not filter. Have Easy spark electrical through a metal pole in water, with another metal pole nearby. You'll get hydrogen and oxygen gas. trap them in a balloon, then light the hydrogen on fire. You'll get yer pure water.

Less complex: boil the water, trap water vapour, repeat as necessary. It's simpler, and there's not a risk of pulling a Mark Watney on yourself.

But there is a big problem with the as well with the pure water. It is essentially like distilled water thus free of all minerals. While that is not poisonous it is not healthy/good in the long term as drinking water. And not just because that would remove a source of minerals for your dietary needs.
Pure water will absorb into your cells amd cause them to explode.
Big oof for ponies.

Well, it's not that cut and dry. It can skew your balance, but if you're also eating a bunch of other things as one tends to do, the effect is minimized greatly. On the other hand, trying to fast AND live on distilled water? Prepare for pain!
