@MaximumEfficiency this is just untrue. Distilled water has a taste and that is literally nothing but water. Clean drinkable Water will have varying tastes dependent upon the minerals contained in the water, and what amounts of those minerals are present. the amount of mineral in the water can be too high to be safe, but that isn’t what is being discussed here.

@James Gardner potentially. If the water is within the watershed of NYC, the DEP police team that can help you with the matter. If it’s outside the NYC watershed, contacting your regional DEC office is the way to go. I believe your regional office is in Albany but I’m not 100% sure on that

I'm actually hoping when they finally bring tunnel 1 offline we get some photos of what it looks like on the inside. No one's been in there for over 100 years, they found out in the 50's the sectioning valves were inoperable, so they couldn't even shut sections off for maintenance. As it is right now, if a major failure happened in tunnel 1 or 2 it would be a huge disaster for the city, the capacity just isn't there until tunnel 3 is fully operational.

@Saosaq Ii that would be an awesome thrill ride, but given the massive volumes passing through, you can bet that what you heard is about another set of tunnels. There is no way to get in the water or out, let alone survive any kind of bump against something protruding from the side even as little as a deck of cards... (I'm a rescue diver. We dive where no other professional divers would dare enter, and I can assure you we wouldn't dive in fully operating water tunnels...) If anything is done, it will be submersible camera pods on cables for visual inspection, ground penetrating radar from the surface and other modern imaging technology, _not_ human "feet on the ground"...

I was an intern in a chem lab in NYC's DEP chem lab one college during summer, measuring fertilizer and coliform concentrations. They knew it was a pretty boring internship so they tried to attract interns with weekly field trips (on paid time! Well, it was minimum wage...) to various water things... we got to go INTO the old croton aqueduct in Ossining. It's super cool.

I’m a pilot and last week I flew into White Plains, right over the Kensico Reservoir for Runway 16. It was a gorgeous summer evening and all I could imagine was paddle boarding on the beautiful lake I was flying over. I noticed that there was no traffic on the water and no houses on the shore which seemed strange given the lake’s proximity to a huge population center. Later I figured it had to be part of the city’s water supply to enjoy such a lack of disturbance and I got to thinking about what goes into keeping NYC hydrated. This video had perfect timing to my logistical ponderings. Thanks for some more outstanding material.

Im from new york and when i was in elementary school we took part in a program that connected upstate schools and downstate schools to learn about the water program and connect the two. it was really cool because we got to go upstate to the reservoirs and do the filtration tests. the program was funded because there is some animosity because the city flooded multiple towns in the creation of the reservoir and many people here dont even know the history

Thank you for making a video on this topic. I’ve been acutely aware of the complexity of NYC’s water source since I learned that my great great grandfathers farm was purchased via eminent domain along with the whole town of Cannonsville. That town no longer exists , along with many other towns, as they were bought to flood for these reservoirs. The buildings and churches still exist under the reservoirs today. The only thing that was removed was graves.

its interesting that the next longest tunnel is for the Helsinki water supply which is a substantially smaller city and the tunnel is only about 10% shorter :D though the bedrock there is very stable so probably more afordable
Cupriferous Catalyst
I wonder how similar it is to the bedrock here in Stockholm. All the new subway lines here are built really deep underground, and from what I've heard it's because it's one of few regions where the ground conditions are so good for digging that it's actually cheaper than the infrastructure modifications required to build the same train line on land. I'm sure there was a more detailed explanation in the video I learned it from, but I'm no expert so all I know is that tunnels here are easy to dig because of the rock itself, and I wouldn't be surprised if conditions in Helsinki are pretty similar!

I grew up with the Croton River Reservoir systems in my everyday background in Putnam County NY and was always in awe when I was told that (most) bodies of water I saw everyday were the Citys water supply. Most of my summers were spent hiking and fishing in NYC DEC controlled areas. Winters were spent walking on the ice watching the icefishers. The Citys land ownership has made the county artificially rural. This video spoke to me personally as I have spent time at almost everyplace you have shown. My great great grandfather emigrated from Italy to work on the New Croton Dam. This system and the infrastructure in it helped spark my interest in engineering at a really young age, and I went to college in the Catskill region near Kingston NY. This is also the most concise yet detailed explanation of the system I have found that taught me a few things I didn't even know despite having seen this entire system in the background of my life. Well done.

I spent much of my childhood in the Catskills, especially by the Ashokan Reservoir. There are trails on the dams and dykes along the banks and on an old rail corridor that was until recently supposed to be restored as a tourist rail operation. Fishing is allowed, but only in flat bottom rowboats and you need a permit to go out. There’s a ton of wildlife in and around the reservoir as the Esopus Creek which feeds it is a trout stream. Various waterfowl can be found on and around it and there are at least three nesting pairs of bald eagles by the shores.

When he said the physics of siphons was not fully understood, I had to remind myself that this was not Half as Interesting
Edward
Edward Aylar önce
I'm an engineer who's worked on the NYC system. We've used actual siphons to temporarily release reservoir water while the outlet pipes are being rehabilitated. There are height limits on siphons because the water is rising above its static pressure line. However, the water supply tunnels are inverted siphons, where the water goes down and then comes back up. There are no limitations on the depth of an inverted siphon.
Ryan Beesley
Ryan Beesley Aylar önce
@Space Elf Downlink part of the problem with your statement is, what does pulling a vacuum mean? We actually have a very good understanding of siphons in a localized system. If the exit of a siphon is below the entrance, and the siphon is sealed so that neither air nor water can escape the siphon except through the entrance or the exit, then a volume of water completely occupying the siphon so that air cannot bypass it, will exhibit the same dynamic pressures at the same elevation throughout the system. This is because fluids move from high pressure to low pressure to equalize. The pressure in the siphon itself is facilitated from the atmospheric pressure of the upstream body of water supporting the column of water. An inverted siphon works for the same reason. It isn't creating a vacuum because you can't pull pressure, but you can push. Thus the low pressure doesn't pull the fluid into the space to fill the void, but it does allow the supported column of fluid to be pushed into the vacuum to equalize the high and low pressures. I think the part which is not understood is how this works over a large distance where the atmospheric pressure at the entrance is different than that of the exit. This is no longer something which can be understood as a local system. However, I think I disagree with that assessment. It is still a localized system governed by the same localized system as before, just segmented into much smaller units. Measured at say every foot, it remains a question about static pressures in that segment and fluids moving from high pressure to low. I think the physics behind a siphon is well understood in principle, but beyond a highly controlled and localized experiment, there is a lot which makes things a deal more unpredictable.

@JamEngulfer What does "fully understood" mean? Knowing the very basic operating principle? Or being able to create an experiment and have a theory that will predict *everything* about that experiment *precisely*? There are a great many things where the former is done, but the latter isn't, because there's always imperfections and details missing that make the prediction unreliable/inaccurate

As a New Yorker, being able to drink good tasting tap water is great. I recognize that not everyone has that privilege, so I am grateful for it. Also having lived in a place where I could basically see the Kensico Dam from my house, it's quite a sight. Not monstrously tall, but impressive nonetheless. And the little green at the base of the dam is a great place to relax.

I studied at Cornell University over a decade ago. I took a microbiology course and as a side project we looked at cryptosporidium parvum oocysts (ie. parasite eggs). These oocysts are spread by cattle manure and can contaminate drinking water causing diarrhoea. There was concern they could contaminate Catskill/Delaware aqueducts because there was runoff from surrounding dairy farms that drained into them.

Hey there, I used to work on the Kensico Reservoir in 2018-2022 as contractors for NYCDEP for the Waterfowl Management Program.

It was a cool job and the reservoirs are beautiful. Nice video!

Thanks for calling it the Tappan Zee Bridge, though I don't know if that was on purpose, instead of the Governor Mario M. Cuomo Bridge. No one local calls it by that name because the State Capital took over naming it without any support from the locals of either county the bridge connects. There's been a political movement from both counties to have it rename to something that locals would agree on.

@Mike B As land develops, it gets covered and can't absorb as much water and standing water in fields is tolerable. Flooding of residential areas is a health risk. Hence, put a pipe in to drain it and while you are at it use the pipe as a sewer. They didn't even treat it for 70 years, just move it away from population and diffuse in larger body of water. Separate systems being worth investment is a post 1950 concept.

How in hades does "architecture" even pretend to comprehend aquatic ecosystem biology? With that said -- yes, the whole NYC metro area is an ecological nightmare, as is any overgrown, densely populated city. People are so vain in their naivete about matters of long-term aquatic ecosystem health, as if nature takes care of itself despite human intervention. Look at Lakes Powell and Mead right now -- dewatered, to turn deserts into grass-covered artificial landscapes. The Los Angeles River has not run for about 70 years now, thanks to "development." Artificial water transport systems were created to help LA "grow" despite having no more water for what then existed. People consider this "progress," though they don't even pretend to wonder what exactly constitutes "progress" when you are destroying the ecosystem you depend upon for life.

Are you referring to rain water and sewage systems? If yes then not only do I agree but I really to know what genius decided to combine those two things. It's really not natural to not allow rain water to seep into land. I wonder if taking all that rain water and not letting it saturate acres and acres of land. That land saturated with water makes humidity on hot days. Humidity on hot days causes clouds and clouds cause rain to fall. I'm not suggesting that's true, just asking a question.

Its an issue in many older cities in the country. For the last couple of decades, Seattle has been building a series of huge tunnels that serve as holding tanks for storm run off until the sewage treatment plants can catch up. Seattle is also doing a lot to divert runoff at the source. Chicago has been at it even longer, but they aren't doing much to divert at the source.

@SofaSpy The LIRR connection is nearly done and is scheduled for completion this year. It's officially called East side access. What a wonderfully creative name for a multi-billion dollar project. Politicians are not supposed to be creative, they are managers. Virtually all projects are privately inspired. There is a new project for Penn station in the works with wide ranging construction effects. from the 2nd ave wiki; "A 1.5-mile (2.4 km), $6 billion second phase from 96th to 125th Streets is in planning and is expected to open by 2027-2029."

@fire surfer @fire surfer 2nd Avenue Subway has been delayed for many decades and it's not 20% really completed. They only built so far. The section in midtown Manhattan. The real project is supposed to go all the way up to the Bronx and all the way down to the lower east side of Manhattan. , The Long Island railroad extension to Grand central's terminal started in the 1960s but just like the 2nd Avenue subway construction started and stop constantly and was delayed decade after decade. The tunnels under the East River work built in the 1960s. Without even being connected to any tunnels on the mainland. Hudson Yards was privately funded by a developer. Sadly, if it's not infrastructure that people can see, politicians don't have the political spine to continue building it because the public thinks it is a waste of money, and they won't get re-elected. For example there are a lot of new upgraded subway stations in NYC but the subway system train signals were never updated and we're still using early 1900s technology. Only recently have they begun to upgrade the signals to be a computerized system, it's slated to go live in 2026

According to Food Theory (spinoff channel from Game Theory) New York's water has lower chlorine levels and higher fluoride levels than other places in the U.S., which allows yeast to do its job better and longer before the chlorine kills it off. That extra yeast time allows the pizza dough to stretch extra thin without breaking, and affects the flavor.

Interesting, I was just in New York yesterday and pondered this same exact question while overlooking the Hudson River - how such a massive population center surrounded by undrinkable water can support itself. I checked the maps and saw basically no substantial reservoirs nearby and no rivers besides the Hudson which, just by looking at it, definitely isn’t drinkable.

If you go all the way to the source, the Hudson River is actually a freshwater river stemming from a natural aquifer.

8:15 I don't think the tunnel acts like a siphon, since the water moving up and down does not rise above the level of the original reservoir. Water can go down and up a pipe because the higher pressure at the bottom pushes water upwards in the forward direction away from the source. I've never heard of such big mysteries in hydrodynamics to warrant calling it "not fully understood"; what competing theories are there?

As a native New Yorker this video was pretty accurate and answered a few questions I had about how we manage our water system. I’ve always been mystified as to how we can manage our water so we’ll that even tap water is safe to drink. I wish my parents country could learn from this but it’s tough since it’s Mexico which is prone to quakes. Anyways great video dude!

@whodoesntlikesurfing I mostly drink unfiltered well water which has no taste at all, and also regularly drink NYC tap water. For the most part, the water lacks any taste or smell. I’ve only had problems when drinking from taps connected to older buildings/pipes. Also worth noting that most large buildings contain their own water filtration systems as a safety precaution (despite it not being needed). It’s rather unprecedented for a megacity such as NYC to have such good natural water quality, and an abundance of it too.

@David Devenport it’s awesome that is still an option in some areas. Where I live in the Midwest our watershed has so much agricultural that not filtering our water would be extremely unsafe. We have good coagulation often putting out post sedimentation water with turbidity less than 0.5 ntu where as EPA maximum is 0.3. Post filtration we typically put it out around 0.06

It's Amazing how this makes NY and Marseille similar : Marseille had the same problem during the 19th century so they build an 80km canal to take water from a nearby river to the city only using physics, they had to build what is still today the biggest stone made aqueduct in the world. Now Marseille is renowned for and proud to have the best public water in the country for the same reasons as new York

A lot of really excellent information is presented in this video! Thanks to Wendover Productions for the video. However, I would like to point out that the bit about siphons was not completely correct. Siphons will fail if the crown, the maximum peak of the bend, exceeds approximately 10 meters from the upper reservoir. The actual height depends on barometric pressure. At this height, the downward pressure of the column of water "pulling" on the water at the crown reaches barometric pressure and the water effectively boils and forms a vapor bubble that would cause the siphon to stop. This is the similar to the principle that mercury barometers use to measure atmospheric pressure.

For many years, my family owned some land on Mombaccus Mountain, at the edge of the Catskill Park, overlooking Ashokan Reservoir. It was always a beautiful spot, now even better with the addition of the adjacent rail trail. An older cousin was one of those scientists working for NYC's DEP, and he told me a bit about how the system works. I also was once an NYC employee, and a coworker who used to be a sandhog, got me a quick look at NYC Water Tunnel 3 in the early 90's. Very cool. If you know where to look, you can easily trace parts of the tunnels as they pass thru Westchester, Putnam, & Ulster counties by the berms that cover them. The entire system is world class, and so is the water.

Water tunnel #3 was started in 1970 and was originally scheduled to be completed in 2000. That didn't pan out. The Feds wanted NYC to build a water treatment plant for the entire Catskill system, but the price tag for such was absolutely astronomical. So all the small towns in the Catskill/Delaware water shed got waste water plants instead. You should have shown all the other connecting tunnels that tie the Catskill/Delaware system together.

The NY legislature is still talking about renaming the bridge, either appending Tappan Zee to it, back to honoring Malcolm Wilson, or straight up just naming it the Tappan Zee." This is pure bs politics from the legislature.

I’m a pilot and last week I flew into White Plains, right over the Kensico Reservoir for Runway 16. It was a gorgeous summer evening and all I could imagine was paddle boarding on the beautiful lake I was flying over. I noticed that there was no traffic on the water and no houses on the shore which seemed strange given the lake’s proximity to a huge population center. Later I figured it had to be part of the city’s water supply to enjoy such a lack of disturbance and I got to thinking about what goes into keeping NYC hydrated. This video had perfect timing to my logistical ponderings. Thanks for some more outstanding material.

What’s even more interesting is that the cities jurisdictions span even further beyond the reservoirs shown here. There are multiple sewage treatment plants in upstate New York that are owned and operated by NYC. Most of those plants discharge into the Esopus Creek, Neversink River, and Deleware River, downstream of where the water diversions are. So the actual span of the operation is even larger than we see here! It’s really amazing actually.

@heidi Rabenau I found the Tomorrow's build video gave way to much credit to the hyperloop which is obviously failing in the real world, and I still believe that hyperloop has basically no use cases (just use a train lol) but the real engineering video on spinlaunch was actually very insightful and well made, and making launching satellites cheaper is a real problem that is worth attempting to address. The working 1/3 scale prototype launching at Mach 1.6 is at least convincing enough evidence to continue development I think.
