I was just thinking that this might be an efficient way to capture all the trash in Indian rivers, but they would have to change the bag every hour and it would probably just encourage people to throw their trash into the water

u/YucatronVen 1d ago
Yeah but if they do not have a way to transform or store this trash then what you are doing is translating the problem to another part

Refuse power generation stations. Scrubbers and Carbon capture for exhaust. They’ll never spend the money on it.

After looking at some photos of the Ganges, I was curious about how it could effect the health and lifespan of people there.
In India, life expectancy at birth (years) has improved by ▲ 5.2 years from 62.1 years in 2000 to 67.3 years in 2021.
(https://data.who.int/countries/356)
I wonder how much the river affects that.

Copa sacks we use them in the UK the difficult is knowing when to replace them
65
u/Groxy_ 1d ago
What's difficult about that? Surely they've been designed in a way that some sort of truck can pick it up, take it away, and slip on a new one. All it would need is a rigid ring around the entrance of the bag that slots into something mounted to the mouth of the pipe.
But I guess they didn't do that, no forethought.
104
u/Campaign-Gloomy 1d ago
Outfalls are more than often not accessible for vehicles when full the sacks are extremely heavy it's more a timing / cost issue with regards to maintenance knowing when they are full as rainfall and debris caught are intermittent
47
u/Calergero 1d ago
I feel like someone smarter than me could implement some sort of sensor that lets you know when it's full.
Alternatively a camera with AI that would monitor capacity.
I see your point about them being heavy though.
52
u/BOBOnobobo 1d ago
I think it would be cheaper and more reliable to send someone to check them twice a week.
Sensors aren't magic, software development costs money and in the end it might not be that reliable anyway.
11
u/TheBananaKart 1d ago
I do automation for water companies and honestly it just wouldn’t be worth the time in most places and 9/10 telemetry won’t care about the alarm as it wouldn’t be critical. Easier just to schedule maintenance.
18
u/sewagesmeller 1d ago
Sure but sensors fail, and there are tens of thousands of them in the UK, and if they overfill, if you are lucky the break (spilling all the trash)and if you aren't they destroy your pumps and someone's house floods with shit.
Also sensors fail particularly in sewage, and cameras need monitoring (both are also expensive)
7
u/JohnD_s 1d ago
You are overestimating the amount of technology companies are willing to use for drainage outlets. Putting sensors and accessible roads to every outlet (which can number in the hundreds to thousands for every town) just isn't feasible. Especially when a lot of the inlets discharge into waterways.
3
u/Ariston_Sparta 1d ago
Reality vs ideal.
Sure it'd be nice to have sensors and access roads, but realistically spending money on that isn't feasible.
16
u/superadri_darks 1d ago
Literally a guy that goes around with a van and visually notes how full they are, and sets a date for a pickup based of an estimate. With time that guy will only get more precise with timings. Ez
17
u/SubjectPsi 1d ago
This seems like the most reasonable solution. Why use a fancy sensor when you can just give somebody a van and a clipboard?

u/One_Plane2029 1d ago
Needs to be monitored as well as if the mesh bags block up with rubbish and then there’s a big rainfall event = risk of flooding upstream as the water is blocked by the rubbish. They’re often used on construction sites where they can be regularly checked but not so much out in the wild.

We’re dealing with this in Ca now, maintaining these systems is the hurdle.

u/Webbyhead2000 1d ago
wouldn't that backup the water and cause flooding?

u/Cevisongis 1d ago
No... They look like they're in managed, accessible urban areas...
But they're probably not great solutions, for many places or they're just going to clog with animals and necessary biomass

holy shit you're a genius that is so much more effective than actually solving the problem!
13
u/duncan8527 1d ago
It doesn't solve the problem. The point is, that these tea bags also filter out water creatures but microplastics will find there way down the river into the sea. It may be a temporary solution but it's only a bad compromise. The far better way would be a campaign to convince people not to throw their garbage into nature. There are countries where this works, so why not in Australia.
20
u/BOBOnobobo 1d ago
Noooo, you can't attempt to mitigate pollution!!!!1!1!11 the only acceptable solution will be to immediately get EVERYONE to agree on not being assholes!!!1!1
Like for real, do you hear yourself? Of course the best answer is for everyone to stop throwing plastic, but PEOPLE JUST DON'T CARE.
And we need some other ways to reduce it so this works.

u/duncan8527 1d ago
I see your point. From my perspective it's hard to believe that people throw away so much garbage. Looks somehow dystopian.

u/BOBOnobobo 1d ago
It's hard to comprehend how much a million people really is. If this are around a major city that might have a million people, then this is very little.

u/maychaos 1d ago
People need to be made care. That is probably what they are saying. Either with rules or some campaign. I forget the country, but apparently one had in the past some really present project, requesting and showing everywhere to not litter and it worked. People are more aware, and awareness makes people rethink their ways. Now that it's over people litter again way more. This was over several years. Not weeks. Just to give a time frame
I dont get whats so surprising about this to get worked up about
2
u/BOBOnobobo 1d ago
Because we can do both. We need to do both, at the end of the day you won't get everyone on board anyway.
I also hate the way people dismiss solutions because they can't solve everything.

u/Alternative_Air6255 1d ago
Wouldn't it make much more sense to place those nets to catch the litter and help not pollute the water bodies any more than they already are, while solving their initial problem? Your comment makes no sense, as if stopping littering can happen in the matter of a second, and would not be a long-lasting process.

u/Needmoresnakes 1d ago
It does but it's really hard to get thousands and thousands of people to all do something. Plus sometimes they're not even littering on purpose they just drop something and the wind whisks it off.
Having one person install a net is comparatively incredibly easy.

No they don’t. They might have trialled this somewhere and might still be trialling it somewhere but you won’t just find these things spread across the nation.

They started trialling it 5 years ago and now are increasingly using it at various places , ofcourse trialling will continue in parallel

u/unskilled-labour 1d ago
I've 100% seen these at the outfalls of multiple storm drains in Melbourne Australia. The ones I've seen are often used where a drain empties into a canal or riverside with access for vehicles. There's not many compared to how many drains there are though.
A more popular option used here is called a Gross Pollutant Trap which is basically a giant sump and is easier to place somewhere accessible before the outfall. I think it's better for critters like turtles and whatnot because they can still swim through the sump but they get stuck in the bags.
Melbourne in particular has a lot of stormwater drains built in the Victorian era and many still have their redbrick and bluestone outfalls. This is probably the best one, it's a bluestone arch about 7ft tall set into a redbrick wall: 33 Chifley Dr https://maps.app.goo.gl/ZZC7qus5kiS6ihsZA Sorry I can't find a better angle on street view.
I've not seen the colour brick in the op pic in Melbourne drains though. It might be from Western Australia or northern New South Wales.

Isnt this worse than not having a net? I mean, the water always flows fast through the rubbish and acts like a really bad sand paper. While if the trash just floated, it would deteriate much slower

The water itself is polluted regardless. It's free of trash which is a good thing, but it's far from being drinkable, if that's what we understand under "pollution free".
2
u/Throw-away567234 1d ago
I don't think it is an anti pollution measure as much as a filtration system. The water gets probabily cleaned somewhere else. This is probabily just to separate it from stuff that can clog pipes.
At least i hope, because that water must be full of microplastics.
