REPORT.
Dodabetta Upper Reservoir.—Fœcal bacilli are present in 20 cc. The organisms are not objectionable
themselves.
Dodabetta Pipe Line. —This is extremely a good water showing no fcecal organisms in 50 cc. The total
colonies per cc. is as low as 32.
Dodabetta Lower Reservoir. —This shows fcecal organisms in .1 cc. The organisms are not objectionable
in themselves, but it is difficult to explain the large number present.
Tiger Hill Reservoir. —Fœcal bacilli are present in 1 cc. The organisms present are not objectionable.
Tiger Hill Pipe Line. —Fœcal organisms are present in 20 cc. The decrease is due to the action of
the
pipes on the water.
Marlimund Reservoir. —Fœcal organisms are present in 20 cc. They are not objectionable. This sho
w
great improvement on last analyses.
Marlimund Pipe Line. —Fœcal organisms are present in 10 cc. The organisms present are objectionable
in themselves.
Kodapamund Reservoir. —Fœcal organisms are present in 20 cc. They are not objectionable.
Old Ooty Cistern. —Fœcal organisms are present in 10 cc. Those that are present are not satisfactory.
Chemically the best water of all is Kodapamund. All the others may be looked upon as very li
ttle
short of good waters, Marlimund Lake showing most pollution. This may be of a vegetable origin.

REPORT.
Samalcotta Canal.—Fœcal organisms are found in this sample in 5 cc. of the water. Those present,
however, are very highly Objectionable and suggest recent pollution along the banks of the canal.
Th
e sample taken from the storage tank shows fœcal organisms present in .1 cc. Those present are not
objectionable and show that the water has undergone a certain amount of storage and purification.
The sample taken immediately after filteration shows no improvement in the water-supply.
Two samples taken from the distributary system show that the water has undergone a fair amount of
purification due to the action of the pipes, fœcal bacilli being present in about 3 or 4 cc.
Chemically the canal water shows a large amount of pollution and the filtered water showing that only
very partial purification has gone on in the filters.

Storage tank.—Fœcal organisms are present in .1 cc. These are not very satisfactory. The pollution
is due to the recent rains.
The sample after filteration contains fœcal organisms in 1 cc. They are not objectionable in themselv
es
Samples taken from the distributary system show considerable improvement due to the action
in the
pipes, fœcal organisms being present in about 5 cc. This, however, does not apply to the sample taken near
the railway station in which fœcal organisms are present in no less than .01 cc. Probably a collection of si
de in this pipe is the cause of deterioration. This pipe should be scoured out.
Chemically the lake water is a soft water but contains considerable amount of vegetable organic matt
er. After filteration the waters is considerably improved.

Report on the Town Water Supplies of the Madras Presidency
for the quarter ending 30th September 1909, being Part
II of Appendix II to the Annual Report of the King
Institute of Preventive Medicine, Madras, for the year
1909.
Guntúr.—A notable point in the results obtained this year was the fouling of
water consequent on its passage through the filters and the pipes of the distributary
system, the spring water containing few fœcal germs and these of an unobjectionable
kind. Last year the results were very different. The spring water was much worse,
but filtration improved it. The samples from the distributary system this year show
a slight improvement as regards fœcal germs, but have very high total counts.
Coonoor.—From all the points the water was examined this year ; definitely
better results were got than those obtained last year.
Ootacamund.—As noted on other occasions the waters from different parts of
the system vary in an inexplicable fashion. Thus this year the Dodabetta system
is much better than last year, but the Tiger Hill Reservoir water and the Marlimund
water, especially the latter, are worse. This year the Tiger Hill Pipe Line was
extraordinarily pure ; last year it was similar to the reservoir water. The waters
from Kodappamund Reservoir and from the Old Ooty Cistern are much as they
were last year.
Tirupati.—This year the river was in flood when the samples were taken, so it
is perhaps not surprising to find the unfiltered water worse than it was last year.
The filtration is still as it was last year thoroughly ineffective. Huge total counts
in the water of the distributary system is a new feature this year. Possibly the bad
filtration is the cause of this.
Kurnool.—Meteorologically the conditions are similar during the two quarters.
The water in the tanks is however worse than it was last year, but filtration has
improved it, so that the filtered waters on both occasions are fairly alike. The water
from the distributary system is better this year.
Vizagapatam.—No useful comparison can be made as the samples were taken at
very different dates in the two years, and the meteorological conditions were also
totally different.
Cocanada.—There has been heavy rain locally here this year and the water
shows extensive signs of pollution. The unfiltered water was better last year, but
the filtration spoiled it to an even greater extent than this year so that the final
result was worse. The results got from the samples taken from the distributary
system are fairly similar.
In making a comparative study of these two corresponding quarters it must be
borne in mind that in 1908 the medium used was bile salt glucose broths, whereas
in 1909 bile salt lactose broth was used. The latter narrows the result down much
more strictly to germs of animal origin. The comparison made above therefore is
not between fœcal germs in 1908-1909 but between fœcal germs in 1908 and glucosce
fermenters in 1909.
Nellore.—No figures are given for rainfall last year, this year the river is in
flood. There is no improvement however in the filtered water or in that from the
distributary system. The water is in a bad state.
