Sewers from Scratch vs. Victorian Patchwork
Episode 3980
Published 1 month, 2 weeks ago
Description
Most city sewers are Victorian-era patchworks, but some were built from scratch. We explore greenfield systems like Brasília and Songdo, why no city has ever ripped out its entire network, and what it's like working underground. The answer to "which is better" might surprise you — and it involves IoT sensors bolted onto 1860s brick.
