What If Machines Completely Replaced Manual Scavenging in India?

Manual scavenging is officially banned in India, yet sanitation workers still die while cleaning sewers and septic tanks due to toxic gases such as hydrogen sulfide and methane.

Technologies like suction-cum-jetting machines, hydrovac trucks, and robots such as Bandicoot already exist. In theory, they can significantly reduce or even eliminate the need for humans to enter hazardous spaces.

But if the technology exists, why are workers still being sent inside?

Some possible reasons:

- Hiring daily wage workers may be cheaper than renting and operating machines.

- Smaller municipalities may not have enough equipment.

- Maintenance and operator training are often inadequate.

- Enforcement of existing laws remains weak.

- Economic pressure forces workers to accept dangerous jobs.

My question:

If India made mechanized sewer cleaning mandatory in every district, how much could this reduce sewer deaths, and what barriers would still remain? Because today, also many deaths are felt.

Pic 1: A worker filling the gap between the stopper and the slab with sealant. This liquid creates a watertight seal and acts as a buffer for thermal expansion, preventing the concrete from cracking.

Pic 2: Japanese J-Slab tracks.

Pic 3: J-Slab precast unit (L&T factory). The circular cutouts lock onto cylindrical stoppers 👉🏼👌🏼 to prevent the track from moving laterally or longitudinally.

Pic 4: Chinese CRTS III track. It features a smooth surface because the stoppers (shear keys) are hidden underneath. Unlike the Japanese design, it uses no liquid sealant and uses different method to tackle thermal expansion.

Pic 5: Chinese CRTS I. An earlier generation of Chinese track that uses the rectangular stoppers shown here.

This video starts with a fantasy scenario:

“What if naked wires could detect exposure themselves, trigger alarms, and auto-register complaints?”

But the real focus is not science fiction.

The real question is:

Why do exposed dangerous wires remain visible for months even after complaints?

I tried exploring:

- delayed maintenance

- department responsibility shifting

- illegal cable clutter

- public normalization of danger

- and whether technology alone can solve infrastructure negligence.

Many developed countries reduced exposed wire risks using underground cabling and smart monitoring systems, but implementing such systems uniformly across India is far more difficult because of scale, maintenance, coordination, and infrastructure inconsistency.

So the bigger question becomes:

Is India’s infrastructure problem mainly technological…

or systemic?

And can smart monitoring actually work if accountability itself is weak?

I was going to one of my friends place in goregaon using the Western express Highway on my cycle, the road was so bad that my hands and back started paining because of the bumps, are these roads supposed to be so bad or what I mean it is a national highway and the quality is worse than a "chand ka rasta" i don't understand,is there any way in which this can be brought up to the government, it's very very unsafe to ride on such roads as falling becomes much more probable.

Got completely bored while studying today and ended up making this custom map of Patna's ongoing and completed infrastructure projects.

Here is the breakdown of what I marked:

🚇 Patna Metro

• Thin Red & Blue Lines: Metro routes under construction.

🛣️ Major Roads & Corridors

• Light Orange: AIIMS-Digha elevated road/corridor.
• Orange: Atal Path.
• Green (near Ganga River): JP Ganga Path (Marine Drive).
• Another Green (with underground red metro line): Bailey Road flyover.
• Dark Green (near Patna Junction): Mithapur-Mahauli elevated road (near completion).
• Yellow (with underground blue metro line): Ashok Rajpath double-decker flyover.
• White: All interconnected flyovers around Patna Junction.
• Brown: Flyover on Zero Mile/Bypass.

🌉 Bridges & Intersections

• Dark Yellow (at Atal Path start): Lohia Path Chakra intersection.
• Purple (from left to right): 1. JP Setu, 2. Mahatma Gandhi Setu, 3. Kachi Dargah - Bidupur 6-lane bridge.
• Black: Rail Over Bridges (ROBs) and connectors to Ganga Path.

Let me know what you think of this map! Did I miss any??
