CITY WATER SUPPLY

9O9 and 1925 lbs, depending upon the
character and volume of water being
treated, or between OF and 2 grains
per gallon. The solution is mixed
with the water at the inlet end Of the
basin by means of a mechanical mix
ing device.
(c) Filtration. The water is dis
charged by gravity from the sedimen-
tation basin into the mechanical fltra-
ton system, which consists of filter
beds each about 1920 #. in plan by
about AZ fit. deep, containing approx
mately l fit. of gravel and Az #. of
sand above the underdrains. Each bed
has rated capacity of 100000 gal
Ions per day. The units are provided
with automatic rate controllers and
loss of head guages and manual rate
control is also provided for each bed.
The filters are washed by water and
air during the winter months once in
10 to 20 hours and in the summer time
every or hours.
(d) The filtered water is discharged
by gravity into the clear water reser-
Won, a rectangular concrete basin hav-
ing capacity of about $4,000 gallons.
This reservoir is so constructed that
there is continuous flow from the
inlet to the outlet and this is accom-
pl1shed by the concrete pier placed in
the center of the section and extending
from the inlet end to within a few feet
of the farther end of the basin.
(e) COLONIZATION. Liquid chlorine
is applied in the clear water reservoir
within few feet of the outlet pipe,
which discharges the water by gravity
into concrete suction we'll. There
are two manual control Wallace-T Tier
nan type "B" units, and scales are
provided to weight the chlorine cylin-
ders. About lb. of chlorine per mil
lion gallons is applied, equivalent to
OH parts per million.
Consumption and Distribution.
Consumers-6,646.
Consumption-Ave about 5,000,-
900; maximum about 100000; mini
mum about 100000.

Fire Protection-In addition to the
clear water reservoir supply, there is
an elevated steel stand pipe having a
capacity of 100000 gallons, distant
from the pumping station about IN
miles.
Sewerage-The sewage is discharged,
untreated, into the harbor and into the
lake. On the north side there are two
outfalls, Is" and AZ" line, about
n of a mile north of the station. Five
outfall sewers discharge into the har-
Dor, one 3O", three "a" and one 49,.
To the south of the station there are
six outfall sewers ranging in size from
u" to 99".
Daily psychological examinations
of the purified water are made at the
laboratory of the plant and these data,
together with operating results are
submitted to this department each
month. For the purpose of determin-
ing the quality of the raw lake water
and the purified supply at the time of
the investigation, a sample of each
water was collected and forwarded to
the state laboratory of hygiene for ex-
animation. The results of these exam
nations show with reference to the
raw water that it is contaminated,
colon being found present in two of
the three portions examined, whereas
the purified water shows a very low
count, 8 at 20oC and 2 at 37oC, and the
absence of B. Coli in all portions of
water examined, indicating satisfac-
tory purified supply.
The lake and harbor water is con-
siderably polluted by the discharge of
raw sewage and such contamination
places a heavy burden on the filtration
plant. 1t appears that the city officials
have given some consideration to treat
ing the sewage, but nothing definite
has been done in this respect. In view
of the fact that pollution of the lake
is increasing, it is believed that the
city officials should take steps looking
to the development of a plan, provid-
ing for the collection and treatment of
the sewage and thus prevent gross
pollution of the lake which now takes
place and thereby protect the water
supply by lessening the burden on the
publication plant.
Conclusions and Recommendations.
1t may be concluded from this in
vestigation:
That the inspection of the system,
review of the monthly reports, and the
recent bacterial findings indicate salts
factory operation of the publication
plant.
That the water supply is safe at
the present time.
That the lake water in the vicinity
of the plant is considerably contain
mated.
1t is, therefore, recommended:
That the city officials take steps as
soon as practicable looking to the de-
velopment Of plan providing for the
treatment of the sewage to the extent
of tank action, with view to prevent
ing contamination of the lake and pro-
tecting the public supply very
truly, E. j. Tully, chemical engineer,
state board of health.
