Aqueduct and Road building Projects under the Republic

This diagram shows the flow of decision making with respect to very large projects. In the case of aqueduct and road building this function usually fell to the Censors. It encompassed the following:

  • Political consensus (not an easy thing to achieve given the fractious nature of Roman senatorial politics)
  • Substantial state funds (to pay for the large amounts of materials and labor)
  • Mobilization of the technical expertise necessary to plan, build and maintain the projects in question

Aqueducts

There were 11 major aqueducts built in ancient Rome between 312 BC and 266 AD. Five of them were built during the Republican period

  1. Aqua Appia
  2. Aqua Anio Vetus
  3. Aqua Marcia
  4. Aqua Tepula
  5. Aqua Julia

Aqua Appia

  • The first aqueduct, built during the censorship of Gaius Platinus and Appius Claudius Caecus; Platinus located the water source and Appius was responsible for the construction
  • It was 16.5 kilometers in length, traveled mostly underground, but rode on arches between the Caelian and Aventine hills
  • It emptied into the Forum Boarium
Political and Military Implications
  • Response to the inadequacy of the water supply in Rome
  • Was an expression of the rising power of the common people versus the patricians
  • Built despite resistance from the consuls at the time
  • Initiated by Appius Claudius Caecus and the fact that the project went forward was a function of his power and prestige; he extended his tenure as Censor so that he could see the project through to completion
  • Appius acquired even more clients as a result of allocating contracts for successfully undertaking such a large project

Aqua Anio Vetus

  • Built between 272-269 BC with spoils from the Pyrrhic war
  • It was anywhere between 64 and 81 kilometers in length, mostly underground
  • The water was of low quality; used mostly for baths, industry and agriculture
  • Building techniques were much more sophisticated than those used in making the Aqua Appia
Political and Military Implications
  • Waters were used primarily for industrial and agricultural use, which reflects Roman commercial and agricultural expansion
  • Infrastructure expansion followed military success
    • Defeated the Samnites
    • Outlasted Pyrrhus
    • Reduced Bruttians and Lucanians in the South
    • Conquered Magna Graecia
    • Consolidating hold on Etruria and expanding into Gallia Cisalpina (both above and below the Po river)

Aqua Marcia

  • Built between 144-140 BC with plunder from the destruction of Carthage and sack of Corinth
  • Rome’s longest aqueduct, 91 kilometers long
  • Built under the praetorship of Quintus Marcius Rex
  • It was constructed to slake the thirst of a thirsty city that had doubled in size since the last aqueduct was built
  • Brought the coolest and purest drinking water to Rome, especially to the higher elevations of Rome: the Palatine, Caelian, Aventine, Capitoline and Quirinal hills as well as lower elevations such as the Forum Romanum and the southern Campus Martius [Dembskey 2009, Page 111-114]
  • Its water was hard, consequently it left large mineral deposits in the aqueduct channel that had to be frequently removed
Political and Military Implications
  • Paid for with plunder from the destruction of Carthage and sack of Corinth

Aqua Tepula

  • Built 127 BC during the censorship of G. Servilius Caepio and L. Cassius Longinus
  • 18 kilometer long
  • Delivered tepid water, mostly for industrial purposes
  • 75% of its volume was designated for private use
  • 15% of its volume designed for public use
  • Agrippa rerouted its path
  • Introduced to service the Capitoline hill; also the Templum Pacis, Esquiline hill, Alta Semita and Via Lata regions
  • The Tepula built during the turbulent 120s BC; there was a slave revolt in Sicily led by Eunus
  • May have been later (under Agrippa) converted as an ancillary d
