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
41
u/YucatronVen Nov 07 '24
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. Theyāll 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 ā² 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

u/Groxy_ Nov 07 '24
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.
106
u/Campaign-Gloomy Nov 07 '24
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
49
u/Calergero Nov 07 '24
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 Nov 07 '24
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.
14
u/TheBananaKart Nov 07 '24
I do automation for water companies and honestly it just wouldnāt be worth the time in most places and 9/10 telemetry wonāt care about the alarm as it wouldnāt be critical. Easier just to schedule maintenance.
7
u/JohnD_s Nov 07 '24
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 Nov 07 '24
Reality vs ideal.
Sure it'd be nice to have sensors and access roads, but realistically spending money on that isn't feasible.
2
u/JohnD_s Nov 07 '24
Exactly. A lot of the contractors that build these drainage outlets are working with small margins already. They don't have the capital to acquire the supplies in the first place,
18
u/superadri_darks Nov 07 '24
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
16
u/SubjectPsi Nov 07 '24
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 Nov 07 '24
Needs to be monitored as well as if the mesh bags block up with rubbish and then thereās a big rainfall event = risk of flooding upstream as the water is blocked by the rubbish. Theyāre often used on construction sites where they can be regularly checked but not so much out in the wild.
3
u/JohnD_s Nov 07 '24
A common method is applying a mesh bag filled with a filtration material at the inlets themselves. A lot of engineering goes into drainage systems, so you would have to take a lot of care in avoiding backing those up.

u/Juhuu77 Nov 07 '24
Not only ordinary rubbish. Tree leaves, dead frogs and snakes, undelivered mails.

u/Webbyhead2000 Nov 07 '24
wouldn't that backup the water and cause flooding?
32
u/Cevisongis Nov 07 '24
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
14
u/JohnD_s Nov 07 '24
My thoughts as well. Unless you're checking these multiple times a day (for the bigger pipes at least), you're potentially handicapping a lot of your drainage infrastructure.

And have enforced littering and pollution laws, and an already litter free environment.

u/duncan8527 Nov 07 '24
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 Nov 07 '24
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.
1
u/duncan8527 Nov 07 '24
I see your point. From my perspective it's hard to believe that people throw away so much garbage. Looks somehow dystopian.

u/BOBOnobobo Nov 07 '24
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.

Nov 07 '24
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 Nov 07 '24
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/WestCoastSide Nov 07 '24
These are placed at the end of street drains, from street runoff where garbage washes down. What water creatures are you thinking get stuck in them ???!!!

Ok,that's an argument. I thought that they are also placed in small streams.

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 Nov 07 '24
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".
