# Roman Aqueducts
|
|
|
|
## Overview
|
|
Roman aqueducts were engineering marvels that transported water over long distances using gravity, supplying cities with fresh water for drinking, bathing, and sanitation. Rome alone had 11 aqueducts delivering ~1 million cubic meters daily.
|
|
|
|
## Key Facts
|
|
- First Roman aqueduct: Aqua Appia (312 BCE)
|
|
- Total aqueducts serving Rome: 11 (by 226 CE)
|
|
- Combined length: ~500 km (mostly underground)
|
|
- Daily water delivery to Rome: ~1 million cubic meters [^1]
|
|
|
|
## Engineering
|
|
- Gravity-fed: Maintained a consistent gradient (~1:200 to 1:4800)
|
|
- Mostly underground channels; iconic arched bridges were only ~5% of total length
|
|
- Used *opus caementicium* (Roman concrete) and lead pipes (*fistulae*)
|
|
- Settling tanks and distribution castella regulated flow
|
|
|
|
## Notable Aqueducts
|
|
- Aqua Appia (312 BCE): First aqueduct, built by Appius Claudius Caecus
|
|
- Aqua Marcia (144 BCE): Longest at ~91 km
|
|
- Pont du Gard (France, ~19 BCE): Three-tiered bridge, 49 m high [^2]
|
|
- Aqueduct of Segovia (Spain, ~1st century CE): Still standing
