Re: Это миф,...

Возможно, вы правы. Правда, вот что пишут:

Lead for the aqueducts of Lyon (France)
Lead pipes were a major element in the water supply within Roman towns and cities. On the other hand, and in particular in the West, lead pipes were applied in so-called siphons, as in the 9 siphons in the four aqueducts of Lyon (France).
It has been said that, based on calculations from Germain de Montauzan 1908, echoed by Smith 1976 and Hodge 1983, some 10.000 - 15.000 tons of lead were needed, but it never was recalculated.
Hodge's conclusions were: (see Hodge 1992 pag 348-9):

Total weight of lead of all the siphons at Lyon is 10.000 - 15.000 ton
Total length of all Lyon siphon pipes: 150 km (9 pipes per siphon)
Mean weight (if all pipes had the same characteristics): 67 - 100 kg/m (154 - 230 kg/10 ft)

Which could bring us to the conclusion that the option for the use of 1 large pipe in stead of multiple small pipes - often rejected because of production problems - was (also) not viable because of the impossibility to handle the weight.
