1890 Article Gallery Capodimonte Tufa Rock Reservoirs Naples Water Works MAB1

This is an original 1890 half-page article about the Rock Reservoirs for the water supply of Naples in Italy. The peculiarity of these reservoirs lies in the fact that they have been excavated in the solid rock. This rock, which is known to geologists as tufa, which has, since its ejection from the crater, become compact and massive, so that it is sufficiently solid to be practically impervious; at the same time, it is sufficiently soft to make the task of excavating therein a comparatively easy one. The first of these reservoirs--that for the high-pressure service- is that of Scudillo. This is formed of three great galleries of oval section and having a mean depth of 50 meters (164 feet) beneath the surface. Each gallery is 9 1/2 meters high, 10 meters wide, and 114 meters long, and is separated from its neighbor by rock walls 10 meters in thickness. The galleries are in communication with each other by crosscuts. The illustration is of a gallery of the Rock Reservoir of Capodimonte.
