Roman aqueducts are usually reduced to one photograph: a beautiful row of stone arches.
RomanAqueducts.info is interested in everything that happened before and after the arches.
The private site was assembled by enthusiasts including Wilke D. Schram, Cees Passchier, and Driek van Opstal. It contains detailed information on more than 100 selected aqueducts and a literature index covering roughly 600 Roman and some Greek systems.
Then it keeps going.
The plumbing is the interesting part
There are historical and technical introductions, statistics, maps, photographs, bibliographies, aqueducts on Roman coins, distribution basins, siphons, control elements, qanats, gradients, channels, reservoirs, and individual system pages.
One entry for the Cologne aqueduct lists a route around 95 kilometers long, roughly 130 kilometers in total when branches are included, along with cross-section, estimated volume, gradient, and engineering features.
This is why the site works.
The Roman achievement was not “they built arches.” The achievement was surveying a route, finding a usable source, controlling slope, crossing valleys, tunneling through terrain, managing flow, handling maintenance, and delivering water where people needed it.
The authors are also refreshingly clear about uncertainty. The introduction notes that sources can contradict each other and invites corrections, especially where the team has not personally visited a site.
That is better historical practice than pretending the old literature magically agrees.
For webmasters and researchers, the site is another example of what happens when a narrow subject is allowed to become deep instead of broad. A general history site might give Roman aqueducts five paragraphs. This one gives them an ecosystem.

The arches get the postcards. The engineering gets the website.
