Timestamped Summary
00:00
The issue of handling and removing human waste and dirty water has been a fundamental problem for cities since the dawn of time.
01:48
The earliest evidence of sewer systems dates back to the earliest human settlements, with civilizations using shallow ditches and clay pipes to remove waste and excess water.
03:16
The Roman sewer system, known as the cloaca maxima, is one of the oldest existing things in Rome and is still used for its original purpose of removing waste and excess water.
04:53
The Roman sewer system influenced the development of new cities in the Roman Empire, but not all cities in history had sewage systems and many relied on cesspits or cesspools to manage waste.
06:24
The need for sewers in growing cities led to the development of the Parasewer system in Europe, but even by 1914, many homes in Paris were still not connected to it, and London didn't have a proper sewer system until the 19th century.
07:54
Sewage farms were early versions of sewage treatment plants where city sewage was used as irrigation and fertilizer, but they had problems with spreading disease, leading to the development of modern-day sewage treatment plants.
09:25
Sewage can cause problems such as algae blooms, fish deaths, and the washing of sewage back onto land, and it can also contain harmful chemicals from industrial and household waste.
