Mr Bailey says that Albany has the largest
filtration plant in the United States He said to-

Pittshurg has filtration plant under way which
will cost $1,000. and Philadelphia has voted ex-

piled with water from sand filtration plants. The
chief cities which use this system of purifying
water are London. Manchester. Liverpool Ham

DESCRIPTION OF THE PLANT
The l9nd upon which the litter bed is built fronts
the back channel OF the Hudson River north of
Albany Opposite the plant IN the river is a long
narrow island. An investigation showed that the
water In the back channel contained less impu-
rites than that n the main channel. The general
plan OF the filtration plant is that Of a plot OF
ground divided into two parts-One a sedimentstio
basin and the other group Of covered filters The
water passes from the river into the intake pipes.
ana thence into pumping station, the pumps OF
which have a capacity Of is 10000 gallons every
tWenty-rour hours. Upon leaving the pumping
station The water passes through meter, and is
measured. AFTER leaving the meter the water
passes 10 the sedimentation basin through eleven
outlets. These outlets consist Of Pinch pipes on
END pierced with 80 small holes. The water is
thus thrown out IN 80 small streams and be
comes aeratec The sedimentation basin has an
area OF i've acres. and is nine feet deep. To the
now line Of the filters IL has q capacity OF 100000
gallons. The water enters the sedimentation basin
from eleven lulets along side and s Withdrawn
from eleven outlets directly opposite. The filters
are or masonry. and are covered 70 protect them
against the winters. which are severe in Albany.

walls and entrances Of ViJriied brick The
main underoraius for removing the filtered water
are or yitrined pipe. surrounded by concrete, and
are entirely below the floors Of the filters The
gravel surrounding the drains is Of three grades
carefully selected. River sand was used for the
hitter; II being considered the best that could be
used. II was carefully screened before being put
IN the nlters The nominal OF filtration Is
8 900 gallons daily. az which rate each
