The city water is pumped to reservoirs, through a tunnel 9 ft.
Large reservoirs assist to store this water after it is raised, and to equalize its distribution.
The filtering works include 6 lime saturators, 2 mixing or softening tanks, 6 settling basins, 10 mechanical filters and 2 clear-water reservoirs.
The American type of storage-tank is generally employed, in conjunction with clay-lined reservoirs.
Roughly speaking, the district consists of a series of parallel ridges, whose summits are depressed into beds or hollows, along which the rivers flow; while between the ridges are low-lying rice lands, interspersed with numerous natural reservoirs.
