I was wondering why the robots didn't have regular ol' wheels.. one benefit that's coming to mind is that the robot can turn just by adjusting the speed of the spin.

The pipe shown in the video is soil pipe (waste water), which across the network has a mix of old (clay) and new (plastics). There are loads of cracks, deformations, connection ridges, sludge/scale/shit build ups that these wheels would find it easier to climb compared to regular wheels.

Though, I could be completely wrong. Just my initial thoughts.

I work for a water district and review footage of sewer mains. Without getting into much detail, as long as the camera isn’t violently shaky this kind of wheel would be great. Sometimes sewer pipes become offset at joints and because fixing it is expensive as long as shit can still flow it’s ignored. The standard little rover can get over most offsets but debris like a random brick that some how gets in stops it in its tracks. If this new thing can get around obstacles that along would be really good. Also I’ve never seen a gator in the sewer but I’ve seen rats and rat snakes. Coworker saw a raccoon.

In the UK at least CCTV surveys often can’t be completed if there is a large amount of silt or ragging in the sewer. I’d assume in clean water pipes there would be similar issues due to tuberculation in older mains and this may be why they’ve avoided wheels

I’ve never seen a cctv review of a water main, I’d imagine your right but I don’t know. Im the map guy though my review of this stuff is purely for documentation and whatnot so I don’t have details on a lot of the hands on parts of it.

I review footage for two districts one is old enough to have brick sewer lines and yeah a lot cant be complete mostly VCP vitrified clay pipe

So I actually work as a Sewer CCTV camera operator, what is demonstrated in the video isn't anything like what we have. The system in particular we use is made by a company called iBak. It has a camera that can pan & tilt with a +/- 120 degree panning range. The tractor it connects to can survey lines as small as 4 inches diameter.

We do have to deal with stuff like offsets and protruding taps, but we don't have wheels like the one on the video. Ours are typically either rubber or a tungsten composite and both are round like regular car tires, tracked systems do exist as well.

I do know for water there are options to be able to inspect lines from the inside but they can get expensive, mainly due to having to be ultra careful in making sure you aren't contaminating the line/system. That and with the pressures involved it has to be built like a literal tank, even more so than the ones used for sewer inspection. Heck the one I use is about 20lbs of nickel plated brass.

I want to hazard a guess that this style of wheel could also function as paddles better in the event that it gets a little deep somewhere along the line

some_edgy_shit- t1_j2jvmdw wrote

Actually they can get through just fine with regular wheels even in high water. before the rover goes through the sewer main they pull a rotating pressure washer that gets rid of most the grime that would prevent the wheels from getting traction. They get submerged frequently and can handle no problem. Only thing bad about it is there’s nothing to clean the camera after it gets wet so it can ruin the footage. Source I review footage as part of my work

Generallyapathetic92 t1_j2jwsa2 wrote

Not in the UK. No idea what size sewers you’re talking about but never come across anything that does that and sewers being surcharged is often a reason for them being unable to complete the survey.

some_edgy_shit- t1_j2jymsm wrote

I work for a rural water district most lines are 6-8 in. When the camera gets submerged we usually tell the contractor to get new footage. On my end it actually happens fairly often but I have to flag it each time as sagging pipe.

What issues do you usually run into if you don’t mind me asking? I’m curious if it’s much different than here

2

Generallyapathetic92 t1_j2k18cy wrote

So if they need to get new footage I assume that’s because they can’t properly survey it?

Generally debris (from sewer collapse or silt), standing water and roots are the main reasons we can’t complete them. Jetting the sewers may help in some cases but roots can still be problematic even after that.

Water level is rarely due to sagging pipe in my experience as the surveyors can get through some water. It’s normally due to the sewer network being fully surcharged either due to storm events or operational issues.

some_edgy_shit- t1_j2k20zz wrote

Yeah they need to get new footage. What your sayings pretty consistent to what I see. I didn’t bring up roots blocking before because the type of tire wouldn’t help with a root ball. We usually don’t get too many blockages from debris though. The contractor has an issue with trying to save time and they pull the pressure watcher like 20 feet or less ahead of the rover. I’m going to try to attach an image of an odd one

Yeah, depends on the amount of roots in my experience but generally agree it wouldn’t help. Honestly not sure if it will help at all but only reason I can see why they’d do it.

Could be you don’t see many if they are jetting the sewer as standard. Generally not the case in the UK and we’d only jet if there is a need to do so. Assume it saves money overall even if we need to pay again.

some_edgy_shit- t1_j2n7ft6 wrote

If it’s not standard for you it’s probably not standard most places in the us either. I’m split between a county and a military base. The military contract requires we us to jet 10% of the total length of line every year. Thanks for letting me know that through I made an assumption that was wrong.

I don't see how this wouldn't be possible with regular wheels as well. I used to have a toy car that could turn by changing the speed of the wheels, and they were regular circular ones.

I think the shape probably has more to do with traversing terrain easier.

I think the transport is the problem.

You have to convert it to acre feet then the number shrinks and it makes sense. Numbers like billions is to difficult to visualize. So the UK uses about 11300 acre ft per day and you are leaking 2400.

Truesoldier00 t1_j2k4ajd wrote

The robots are good but we have multiple ways to test for leaks. We use smart hydrants which track transients in the pipe. So if something bursts you can find out right away.

You might think “well you would know because water would be coming out of the ground” but that’s not necessarily true. It can take days, or just not show up at all. But the treatment plant can tell us (the city) our usage is high and we should be on the lookout for a break.

We can also use listening devices. Leaks have a distinct sound so you can put a device onto a water valve or hydrant and listen to the main for hissing.

Tyrion_toadstool t1_j2iu0rx wrote

A few years back the area my parents live experienced a drought with no rain for 6 weeks or so. Almost all their grass died, but they noticed some mysteriously green areas in their yard and a small amount of water pooling and they thought their septic tank was leaking.

It turns out the water main that basically ran underneath their property and served the whole neighborhood was leaking. I don’t remember the exact figure, but it was leaking a staggering amount of water - something like 5 or 10 gallons per minute, every minute, all day, every day. Thankfully they live at the top of a large hill, so the water was pulled away from the house and property by gravity and had plenty of ground to seep into.

But without that drought this may have continued for years and years before it was noticed.

Geez. Do you know the diameter of the main? Just curious. Trying to visualize how big it is and how big a crack/break would be to leak that much water.

Shmeepsheep t1_j2jalc2 wrote

That's really not that much water if you've ever worked around utilities. It's about the equivalent of a half inch copper line.

From a quick googling a residential sprinkler system uses between 12-30 gallons per minute. So about half of what it takes to run a sprinkler system

SeriousPuppet t1_j2jgjyh wrote

Wow. Then wouldn't the fixtures downstream (ie where the water ends up, faucets etc) notice a big drop in water pressure?

Shmeepsheep t1_j2jgyk7 wrote

The farther you get from the source the lower the pressure will be. A home only really needs like 40psi to operate correctly and many times has 100+psi that needs to be reduced because of this.

Also a small leak is not going to noticeably drop water pressure in a 6" main

14

Tyrion_toadstool t1_j2j7604 wrote

I do not. I remember it was an old main that I believe was made of metal. It was replaced entirely with a main of much smaller diameter made of an entirely different, modern material (I can't recall what, exactly). We were told the new main would perform as well as the old one, despite being smaller, and that seems to be the case as we noticed no difference in water pressure after it was installed.

We do this all the time now with what's basically a GoPro strapped to an RC car for about 10% of the price. You don't even need wifi for location because you can count the rotations or just measure the string you tied to the end.

These robots don't actually stop leaks. They just spot them. The real trick is getting the pipe repaired which comes at significant expense and inconvenience to everyone in the area.

You can slickline the pipe, but more cost for less infrastructure. But even then it still reduces the pipe's diameter, so you can only do that so many times before you need to whole ass replace the pipe.

Take it a step further.

It's not even needed. I work at a water utility company and we have pressure sensors on the pipes that will alert if there is a drop. This robot stuff is just bullshit over engineering for a problem that doesn't need solving.

The real problem as stated above, is getting to and repairing those leaks.

beamer145 t1_j2kjhtt wrote

I would expect it is still could be useful, unless the sensors allow to pinpoint the target area within a few meters ? Otherwise you have to start digging up the whole pipe section that is covered by a sensor ? Or am i missing something obvious ?

CheekyHusky t1_j2kowel wrote

So the network sensors detect flow / loss of pressure in a section of pipe.

When the team goes out to investigate, they have other sensors that use acoustics to pinpoint the leak. I personally work in software development so I don't actually deal with the leaks myself so unable to explain 100%, but from my understanding they place them at each end of a section of pipe they know there is a leak at, and then the vibrations will pin point where the leak is.

Sorry to be the stop-having-fun-guy but I'm a utility inspector.

We already have these. Pipe snakes and camera rovers that are typically tethered. Manhole to manhole isn't enough distance to really warrant a wireless solution. Especially when you may have to yank it back out when it gets stuck.

They don't really need to be miniaturized more than they are. The only real bottleneck (that puns was for me) is the labor cost. You don't really eliminate that with a more high tech solution. You're really just making IT guys crawl under manholes instead.

The best way to get ahead of this problem is better code enforcement ans spending money on maintenance that has largely been ignored. However, like with all government spending on infrastructure that doesn't get anyone re-elected.

Agree with you, also these "robots" won't be able to work in a pressurised pipe, so what's the point? When potable water mains burst/leak, there are much better ways of finding it than busting the main open at a perfectly good section to put some robots in.

DHFranklin t1_j2kgs90 wrote

Well sure, but pressurized pipe can be tested with hydrostatic testing at fire hydrants. Smoke testing too if they're old school. If they are chasing down a leak, there is a good chance that they will just shut off water for a day over a city block or housing development while they cam the entire system.

Not to be contrary, but I'm sure that what ever instrumentation would be called for to cam the pipe would be the same to have one of these little robots in. If they were faster then tethered robots or you could let a swarm run through pipes, that might be the good cost/benefit.

I would like to see those tiny gimbled drones that are 3" that could fly through 4" pipe.

In waterpipes it’s alao been done for decades, but in much lesser scale compared to storm or sewage pipes. Most of leaks on waterpipes are microleaks and you won’t find them with robots. And there is also no point of repairing them, because even if cost of one microleak is 100 euros in a year ( and that is already not so microleak), finding and repairing it can cost (depends on location) 3000 + euros and up tens thousands.

All the while, these companies are raking in the cash and paying dividends to their shareholders. I genuinely don't care who "owns" the infrastructure, I'd just like whoever owns it to take their responsibilities seriously and keep it well maintained.
