| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Aqueducts (aqueducts) | required | 82% | textbook | Inverted siphons and lead distribution pipes are scoped here as advanced aqueduct features, so an aqueduct system is a direct prerequisite rather than loose context. |
|
| Hydraulics (hydraulics) | enabling | 76% | textbook | Inverted siphons use pressure-pipe behavior to carry water down and back up across valleys; hydraulic understanding enables the design without being the physical component. |
|
| Masonry (masonry) | enabling | 72% | textbook | Aqueduct siphons could use masonry, brick, concrete, or stone support works such as arcades, venter bridges, tanks, and pipe sleeves; masonry enables much of the built infrastructure but is not the siphon mechanism. |
|
| Lead Working (lead_working) | required | 80% | textbook | The node explicitly includes lead pipes, and Roman siphon and distribution pipework commonly used soldered lead pipes, so lead working is required for this combined lead-pipe scope. |
