Aqueducts

2. — Stone or brick work used to build the supporting structures of aqueducts, arches, and bridges.
4. — A built structure that carries water from one place to another, often over long distances.
6. — A curved masonry structure that supports bridges or elevated parts of an aqueduct and helps spread weight.
10. — The regular work (cleaning, repairing) needed to keep an aqueduct working and water flowing.
12. basin (piscina limaria) — A pool where heavier particles and silt settle out so cleaner water continues through the aqueduct.
13. — An underground layer of rock or soil that holds water and can be a source for an aqueduct.
14. shaft — A vertical opening that allows workers to check and repair the inside of the aqueduct channel.
16. (water allotment) — An assigned share of water given to a person or building (e.g., public baths or private houses) from the aqueduct supply.
20. — A gentle slope or incline used so water flows downhill by gravity through an aqueduct.

1. survey — The measurement process used by Roman engineers to keep a steady slope so water flowed without pumps.
3. caementicium — Roman concrete, a durable building material Romans used to build aqueducts, arches, and bridges.
5. (specus) — The open or covered trough inside an aqueduct through which water flows.
7. — A channel or pipe that actually carries the water inside an aqueduct system.
8. network — The system of pipes, channels, and outlets that send water from the aqueduct to fountains, baths, and homes.
9. — A storage basin or tank where water is held before distribution to a city or baths.
11. (bridge) — A bridge-like section of an aqueduct (often with many arches) that crosses a valley or low ground.
15. — A U‑shaped pipe or system used to carry water down and up across a valley using pressure and gravity (sometimes used in aqueducts).
17. (caput aquae) — The place where water first enters the aqueduct system, often a spring or source protected by a structure.
18. — A curved roof or ceiling made of stone or concrete used in tunnels or covered parts of aqueducts.
19. pipe (fistula) — A metal pipe (often lead) used in Roman times to distribute water from the main channel to buildings.
