Julius Frontinus was appointed by the Emperor Nerva to the post of water commissioner for the city of Rome in 97 CE. In On the Water-Rights of the City of Rome he documents his duties, responsibilities and accomplishments during his first year in office. He also sketches the history of the aqueducts and furnishes a wealth of technical data. This is the most authoritative edition of this work to be published to date.
I should read this in the original latin. It is interesting to see, how Roman edicts are issued wrt. to techological marvels, and the policy when it comes to governance.
