I went down to the Noyyal today. Or what’s left of it.
I remember going to that water with my mom to wash our clothes. My chithappa used to walk down there just to take a bath. It was a living, breathing part of the dirt we stood on. Now? It is a corpse. An open, frothing sewer of municipal shit and industrial dye. The rich bastards running the factories in coimbatore, textile units around Tiruppur, and even the fucking municipal corporations just keep vomiting their chemical effluents straight into the channel. You look at it and you want to gag. We all know what happened to the Orathupalayam Dam, which was built for farmers, supposedly, but is now choked with toxic sludge that they had to shut it down. A textbook crime scene. I used to think, maybe, just maybe, our next generation could enjoy a river, which I don’t have a chance of having. Nope. They get a stinking, foaming chemical drain. And nobody with any power actually gives a damn.
But it’s not just the poison. It is the blinding, spectacular arrogance of the people who think they can control water.
Engineers. God save us from civil engineers with their rulers and their fluid mechanics textbooks.
They look at a river—a chaotic, messy, meandering force of nature—and they see a defective pipe. They suffer from this terminal drainage blindness. To them, a healthy stream packed with fallen logs, sandbanks, and wild curves is "clogged." So what do they do? They "clean" it.
They scrape away the vegetation. They rip out the roots. They dredge the bottom and slap concrete on the sides until they’ve bullied a living river into a perfectly straight line. They think they’ve achieved efficiency. They haven't. They have just built a high-speed water chute that flushes everything out to sea before it can sink into the soil.
Nature doesn't do straight lines.
When you straighten a channel, you murder the meanders. You destroy the natural speed brakes. Water needs time to seep sideways, to sit, to recharge the dry aquifers. The old Tamil kings actually understood this. We didn't have beavers to build leaky dams here, but the old kings built the eri tank systems and anicuts to mimic them. Catch the rain, slow it down, spread it out.
Now? The British taught us to draw straight lines, and we never stopped. We just want to push water away fast, and then trap it behind massive, stupid concrete walls.
But water is not stupid. It is patient. And it is incredibly vindictive.
When you build a dam, you trap all the silt and sand behind it. The water that spills out the other side is stripped naked. Hydrologists call it "hungry water." It has massive kinetic energy and absolutely no sediment to carry, so it aggressively attacks the riverbed downstream. It scours away the dirt and tears the banks to shreds just to satisfy its capacity. It eats whatever it can reach.
Take a look at the bridges around here sometime. Some of them look like they’re waiting for a stiff breeze to collapse. That is bridge scour. The textbook engineers cleared out all the wood, straightened the channel, and accidentally turned the river into a hyper-fast pressure washer. The hungry water hits the bridge piers, creates an underwater vortex, and just scoops the foundation right out from under the concrete. The bridge looks totally fine from the road, but underneath? It is hanging in mid-air. One heavy flood and the whole damn thing will snap like a dry twig.
It is hilarious. In a very grim, miserable way.
We traded a self-sustaining biological ecosystem for a giant concrete storm drain, and the drain is actively digging its own grave.
The public screams about flooded streets, and the government responds by issuing fresh tenders for more concrete retaining walls. Because concrete is easy to audit. Nature is messy, and you can't issue a lucrative government contract for "leaving a dead tree in the water." So the default answer is always to widen it, straighten it, and strip it bare.
A river is lawless. Ten thousand river commissions with all the money in the world couldn't actually tame one. We are just arrogant enough to think we can bully physics with a T-square and a bag of cement.
The Noyyal will remember what we did. The dirt always gets the last laugh.
