KURNOOL.
Sample taken—31st August 1908.
Remarks.— The water is taken from the Cuddapah-Kurnool canal which is now in flood. The
water passes into a settling tank, then through filter beds into a storage reservoir
from which the town is supplied by gravitation.
The supply at this time of year is intermittent.

REPORT.
(i) The unfiltered water shows considerable contamination, fœcal bacilli being present in 1 cc.
(ii) The water after passing through the filter beds is very decidedly worse than it was before filtration ; obviously
feltering material is not satisfactory or the working is wrong.
(iii) The samples taken from the pipe line, viz., III, IV, and V, show a great increase in the total colonies and also
increase in the fœcal bacilli. The cause of this may be twofold : (i) either silt in the pipes or (ii) aspiration of contaminated
and water into the interior of the pipes when the supply is cut off.
Recommendations.—
(i) A sample of the filtration sand be sent to the Sanitary Commissioner for inspection.
ii) That the wash-out stop cocks be opened as soon as rain has fallen and water is plentiful and the pipes be
out to remove the silt.
(iii) The pipe line should be inspected for leaks. This does not necessarily mean opening the ground, but a
1 inspection should be made for dampness of the soil ; all leaks should be stopped.
(iv) Whenever water is plentiful the supply should not be cut off at all.

supply is from an irrigation canal local rainfall has not much influence on either
the quantity or quality of the water.
The settling or storage tank usually contains enough water for about 15 days supply,
but when it is pumped full it holds a months' supply,
The supply is intermittent.

Samples taken-15th July 1908.
Remarks.—Water comes from the Vaigi river across which an infiltration gallery is thrown.
The river bed is carefully conserved for two miles above the gallery.
There is practically no above-soil flow in the river at present but sub-soil water is
reached by digging one and half feet in the sand of the river bed.
The water is about at its lowest; no rain has fallen recently.

REPORT.
(i) Water of open stream is very highly polluted, but there are slight indications that the pollution may be
very recent. Fœcal bacilli are present in 1/100 of a cc
(ii) Water from infiltration gallery shows considerable improvement on the stream water ; fœcal bacilli in
This is fairly satisfactory but is capable of improvement -vide recommendation.
(iii) Water from distributary system shows some increase in pollution which requires further investigation.
Recommendaeion.- That the open stream cut parallel to the infiltration gallery be removed at least 60 and
80--100 feet above the gallery so as to increase the filtration.

There has been a fair amount of rain in the form of heavy showers recently over
2 inches fell on the 3rd October and about half an•inch on the 9th.

REPORT.
(i) The Vaigai river water is very highly polluted evidently by the washing of the land by the recent rains
pollution is recent and is of an objectionable nature ; fœcal bacilli are present in 1/100 of a cc. and less. The water is
than last quarter.
(ii) The water taken direct from the infiltration is however a very good water. There are no fœcal bacilli 50
This is a great improvement on last quarter. The explanation of this happy state of affairs is evidently that in the
weather the gallery receives a mixture of true sub-soil water and a little very indifferently filtered " above-soil " water
rains have fallen the water that passes into the gallery is entirely a pure sub-soil water with no admixture. As already
the stream (or above-soil water) is very highly contaminated at this time so that if any found its way into the galley
presence would be immediately detected.
(iii) The two samples taken from the pipes are as good as that taken from the gallery.
The chemical analysis demonstrates the fact that the stream water and the gallery water are in reality diffe
The free and albuminoid ammonia and oxygen absorption figures are less in the gallery water ; this however would not
for remark, but the nitrate figure is much higher in the gallery water ; this is most probably due to the subsoil stream
through some strata charged with nitrates.
The present condition of the water is most satisfaotory.
