REPORT.
(i) The spring water is at this time of year very inferior in quality to the lake water ; fœcal bacilli
are present in the spring in .1 cc.
(ii) The lake water is now much improved in quality owing to the recent rains, fœcal bacilli are present
in 5 cc. If greater care was taken with the conserving of the catchment area, the water would be still better.
(iii) As in the last analysis the filter beds are spoiling a good. water by adding fœcal bacilli. The
lake water unfiltered contains fœcal bacilli in 5 cc., the filtered water in 1/10th of a cc.
(iv) The water in the town pipes is better than the water as it leaves the filter beds, as some of the
bacilli have settled in the pipes in the form of silt. But the silt is adding some objectionable bacilli that have
disappeared from the lake water : Vide sample IV.
This deposit should be removed as often as possible by opening the wash-out cocks.
The chemical analysis of the water shows that it is not a very first class water, but if the filters were
working better a better result would be obtained.
R e c o m m e n d a t i o n s . —
Information is requested as to whether a fine sand is pro curable near Adóni.
The filtering material should be changed.

Samples taken—5th February 1909.
Remarks..— There has been no rainfall at all since November 1st.
The water in the lake is now 7 feet deep. The spring water is not let into the mains at present

REPORT.
The sample from the spring is of fair quality. It contains fœcal bacilli in 1 cc. It is very much inferior in
[illegible] lity at this time of the year to the unfiltered lake water.
(ii) The sample taken from the lake is a very good water. It contains fœcal bacilli in 50 cc. This is due to the

(iii) The two samples taken from the hydrants are of the same quality as that from the filtered reservoir.
Chemically the water is not a good water either before or after filtration. These results also demonstrate the
satisfactory nature of filtering medium because there is little or no purification effected by passing the water through
[illegible]sand.
Recommendation.—It
is absolutely imperative that the present sand be removed and a finer variety put into
[illegible]beds.

Samples taken-9th September 1908.
Remarks.—The water comes from two catchment areas in which are a number of so-called springs.
Surface water in fair quantities finds its way into the supply. The water passes into
a storage reservoir and is gravitated into the town. The supply to the town is
intermittent. There has been some rainfall recently the last amount on the 8th
instant exceeded half an inch.

REPORT.
2 3 9
The water of Coonoor being largely a surface water is contaminated to a considerable extent. There are fœcal
illi in . 01 of a cc. The special varieties present do not indicate very recent pollution.
The three samples taken from various places in the pipe line do not show any marked difference in the quality of the
ter due to carriage in pipes.
One sample however taken from a pipe near the station is inferior to the others. Inspection and further investigation
necessa ry and will be undertaken shortly,- The presence of rain in the hills at this time will cause the samples to be about
heir worst owing to the washing of the catchment areas.
mmendations:—
(i) The pipe line down to the station should be roughly inspected for leaks.
(ii) If the amount of water is sufficient the intermittence of the supply should be stopped.

REPORTS.
The sample taken from the reservoir is of a fair quality only. Fœcal bacilli are present in 1 cc.
2. The sample taken from the service reservoir is worse, bacilli being present in • 1 cc. This is probably
silt in the reservoir.
3. The samples taken from the distributary system show a slight falling off in the number off fœcal bacilli.
B u t i n
the cases decidedly objectionable organisms are present in the water. The sample taken from near the railway station
every occasion is markedly inferior in quality to any other sample in the town. The pipe line should be very carefully
peoted and if it happens that this tap is situated towards the end of a branch that the wash-out valves should be opened
the pipes swilled out. This may remedy the evil.
After settlement chemical analysis of water shows that it is a good water.
