REPORT ON THE WORKING OF THE KING INSTITUTE, GUINDY
to deal effectively with the pollution present in the raw water. As supplied to the town, however,
the water was passable.

Negapatam .— The gallery supply to this town in September 1924 was of indifferent quality.
In February 1925 vibrios were detected in all the samples collected from the distribution system
and there was an epidemic of cholera in the town. Chlorination was recommended and the
epidemic was soon controlled.
Nellore.— The water-supply to this town continued to be in very fair order.
Ootacamund .—The water-supply to this hill station continued to be in good order.
Periyakulam .—The sand filters acted at best as strainers only. The necessity for over
-hauling the filters was brought to the notice of the authorities concerned.
Rameswaram .—The supply to this union continued to yield excellent results.
Salem.—The raw water of Panamarattupatti tank was not in any way improved in its
passage through the sand filters; on the other hand there was deterioration combined with the
production of sulphuretted hydrogen. Even the physical appearance had not improved and the
town received a supply of water, which was a shade worse than the raw water.
Tanjore.—In July when the Vennar was in floods the gallery effected a definite improve
-ment in the bacterial flora, but failed to deal effectively suspended matters in the raw water.
In December, a fair supply at the source was found to deteriorate in transit through fouled pipe
lines.
Tirupati .—The gallery continued to yield satisfactory results.
Trichinopoly .—During the year under report, the infiltration gallery was damaged by
unprecedented floods in the Cauvery. Consequently the raw water from the river was chlori
-nated efficiently and supplied to the town. The municipality was advised to instal chlorination
on a permanent basis in view of the uniformly poor results yielded by the gallery over several
years.
Tuticorin .—The water-supply is entirely unprotected and it is not Surprising therefore that
the drinking water is anything but satisfactory. The urgent necessity for introducing a fully
protected water-supply has been repeatedly urged apparently to no purpose.
Vellore.—The Otari tank having run dry in May, the water from a trench dug below the
bund of the tank was allowed to feed the sand filters. These acted only as strainers, the
improvement on the bacteriological side falling considerably short of the standard. Chemically,
however, the filtrate showed improvement over the raw water.
Vizagapatam. — I n

town, as the filters were being overhauled. In December two sand filters that had been relaid
yielded filtrates of good quality.
Vizianagram .—The gallery yielded variable results. The water was of poor quality in
July 1924 but had improved in January 1925.
Jails.
Bellary .—The drinking water well was found to be highly polluted. The sample of
chlorinated water supplied to the jail population was of good quality.
Cannanore .—In September 1924, both the tope wells yielded poor results bacteriologically,
but in March 1925 the samples from the two wells were of good quality. Systematic bactericidal
treatment was advocated.
Coimbatore .—The aeromotor well and the garden well constituted the supply to the jail
population; chlorination was found efficient and the treated water was of good quality.
Cuddalore .—The water of the " Lake well, " although chemically of a good quality, was
bacteriologically unsatisfactory. Systematic bactericidal treatment was recommended.
Palamcottah .—The raw water from the jail was altogether unsatisfactory; chlorination was
recommended as a routine measure of safety.
Rajahmundry .—In May 1924, the raw water from the well in Block VIII was chlorinated
and supplied and the treated sample was good; but in November, the water had been so overdosed
with chlorine that the sample strongly smelt of chlorine, even after receipt in the laboratory, and
was unsuitable for examination. The necessity for chlorinating supply after carrying out the
field tests every day was again urged.
Salem.—The raw water of the jail well continued to be of poor quality. The chlorinated
sample examined in October 1924 was not satisfactory indicating that the process as practised
was ineffective. The hospital well having run dry, the water from a well in the bed of a nullah
was utilized for drinking purposes. The desirability of extending the municipal supply was
again strongly recommended to the Inspector-General of Prisons.
Tanjore .—The treated water as supplied to the Borstal School children was unsatisfactory in
July, but it was in excellent order at the December examination.
