Why did the Romans build aqueducts and sewers?
When people drink water with poop in it, they can get other people’s germs. They may get sick with dysentery or die. Dirty water was especially dangerous for babies and old people, and anyone who had been sick.
Roman aqueducts and clean drinking water
To fix this problem, many Roman towns built aqueducts. The aqueducts brought in fresh water from the hills outside of the towns.
Did Roman lead pipes give people lead poisoning?
Probably the lead pipes did result in somewhat higher levels of lead, which isn’t healthy. But Roman water didn’t stand in the pipes – it was always running, so it wouldn’t have picked up too much lead. The Romans knew what lead poisoning looked like, and if people had been getting it, they would have changed their system.
How did the Romans deal with sewage?
The Romans also built public latrines and systems of sewage pipes to carry sewage out of the streets and dump it into the river. Roman sewers were a big improvement on Greek sewage arrangements, where many people just poured their waste into the street however they wanted.
Roman public toilets
There were also big public toilets that had room for lots of people at the same time (this one is from Ostia). Apparently, Roman people weren’t shy about all going together in one big room!
Did Roman women use the public toilets?
Nobody knows whether Roman women used these public bathrooms along with the men, but there aren’t any separate women’s rooms, so they probably did.
Unlike latrines in China, in Rome people sat down to go to the bathroom.
Roman sewers – pipes and storm drains
Roman toilets drained into the sewer pipes underneath them. Then the Roman sewers just dumped raw sewage into the river, which was better than leaving it lying around in the streets, but still did spread germs sometimes.
The Romans didn’t have any way of treating sewage to kill the germs, as we do today. And they didn’t understand that germs made people sick.
Some of these Roman sewers are still being used today. In Rome, the Cloaca Maxima, the Big Drain, still carries rain water away from the Roman Forum to the Tiber River.
Sewage collectors and fertilizer
In smaller towns, though – most of the towns in the Roman Empire – there weren’t any sewers. Sewage collectors came through and got the poop from each house and carried it off to sell to farmers to use as fertilizer on their fields, just like in ancient China at the same time.
In small villages (where most people lived), they didn’t even have outhouses, and people just walked out to the fields every morning and pooped there.
