No, it was a soviet thing. Why? Because it's cheaper.

But it's also accidental genius: It has the unintended side effect of bringing the corruption to daylight, literally.
You wouldn't want to know what soviet water pipes hidden in underground tunnels look like. Or maybe you already know from super sus' videos.
No maintenance plans to speak of, decades of ad-hoc repairs carried out not by replacing damaged sections, but by banging on reinforcement plate after another. Everything's rusted to shit. Much of the water is lost to leaks and only god know what kind of shit ends up in the water supply.
