COMPARISON OF SOUTH AND OBISPADO RESERVOIRS.

The two reservoirs are practically of the same capacity, the only

difference being the level of the overflows in their relationship to the

roof, which gives the Obispado Reservoir a slightly greater capacity.

Some comparative figures may be of interest, owing to the differences in

type and construction. Table 7 gives the comparative quantities of

material in each reservoir proper, that is to say, exclusive of the

valve-houses, lay-out of grounds, etc.
