Extract

A good supply of water was rightly regarded as one of the essential commodities for the maintenance of urban life in the ancient world. One of the major problems with which city authorities had to deal was the maintenance of adequate supplies of water to satisfy the domestic, public, recreational, and industrial demands of the inhabitants. The Romans were particularly renowned for their hydraulic technology in general and the construction of aqueducts in particular, often bringing water from great distances. The geographer Strabo praised the engineering skills of the Romans, maintaining that veritable rivers of water flowed by means of aqueducts through the city of Rome. Close on a century later the first curator of Rome's water supply and one-time military governor of Britain, Sextus Julius Frontinus stated the same, if a little more pointedly, when he compared the achievements of the Romans in the field of water supply with the ‘idle pyramids of the Egyptians or the glorious but useless monuments of the Greeks’.

(eds.), Roman architecture in the Greek world (London, 1987), pp. 72–73Google Scholar points out that it was not through lack of the requisite technology that the Greeks did not make extensive use of long aqueducts but the unstable military situation. The siege of Syracuse by the Athenians during the Sicilian expedition illustrates the dangers. One of the actions taken by the Athenians was to cut off the water supply to the city (Thuc. 6.100). In Greece water was brought to Olynthos from springs about 6 miles from the city, see Robinson, D. M. and Graham, J. W., Excavations at Olynthus VIII (Baltimore, 1938), p. 307Google Scholar, Robinson, D. M., Excavations at Olynthus XII, pp. 103–14Google Scholar.

Despite the obvious spectacular structures such as the Pont du Gard, and the aqueducts of Segovia, Lyon, and Rome, in general less than 10° 0 of an aqueduct was usually carried on arched bridges, see Smith, N., ‘Roman hydraulic technology’, SciAm 238.5 (1978), 154Google Scholar; Hodge, , op. cit., p. 129Google Scholar.

25. Only one instance of the interconnecting pipe was found in situ but the partial collapse of the party walls between tanks, at the point where such pipes were located, indicates that all the internal partition walls were so pierced.

27. The Romans were fully conversant with the technology of the syphon and it was probably utilized more extensively than has been supposed, see Hodge, A. T., ‘Syphons in Roman aqueducts’, PBSR 38 (1983), 174–221, esp. 220–1Google Scholar. The Kremna syphon was less than 300 m. in length, compare Aspendos (0.8 km.) and Les Tourillons, supplying Lyon (ca. 6 kms), see Hodge, ibid., 185–9. Hodge, ibid., 220, calculates that the total length of the syphons in the Lyon area comes to 16.6 kms!.

29. Vitruvius, , op. cit., 7.6.8–10Google Scholarrecommends the use of clay pipes because they are cheaper, easy to construct and maintain, and because water carried in clay pipes remains pure. Terracotta pressure pipes were used in aqueducts in Spain, Hodge, , op. cit., 175Google Scholar. Lead, stone, and terracotta encased in masonry were also used, e.g. see Hodge, ibid., 181–2, 189 (lead), Coulton in Macready and Thompson (eds.) (1987), p. 74 (stone), Thompson, , ‘The Roman aqueduct at Lincoln’, ArchJ 111 (1954), 119 (terracotta sheathed in concrete)Google Scholar.

30. Vitruvius, , op. cit., 8.6.8Google Scholar recommends a minimum thickness of two digits. As far as the author is aware the Kremna pipes are the thickest yet found.
