REPORT ON THE WORKING OF THE KING INSTITUTE, GUINDY
Kilpauk. The filters considered as a whole did not function well on either occasion. At the
July examination the sample of a mixture of raw and filtered water drawn from the test tap
showed no improvement over the raw water and was definitely worse than the raw water at
the March 1924 examination. The water as supplied to the consumer was little, if any, better
than the raw water.
Madura .—The Kochadai gallery yielded as usual a water of better quality than the
Arapalaiyam gallery ; in October, however, the latter yielded a water of a passable quality.
Two samples were sent on 14th February 1924 by the Chairman, Municipal Council, and
cholera like vibrios were detected in them. The matter was brought to the notice of the
sender, Director of Public Health and Sanitary Engineer.
Masulipatam. —The mechanical filters in this station functioned well during the year.
Negapatam.—The gallery supply to this town yielded variable results, At the first
examination the results were satisfactory, while on the second occasion the water was of
indifferent quality. Deterioration was found to occur in the distributary system.
Nellore.— The supply to this town continued to be in very good order. This is the only
supply in the Presidency with a uniform record of good results during a five-year period.
Ootacamund.—The supply to this hill station was shown by the results of two exami--
nations to be in good order. In July the samples from the Tiger hill and Marlimund
reservoir showed somewhat excessive figures for organic matter.
Periyakulam.— The sand filters have not been working efficiently during the year. The
supply to the town is, therefore, of poor quality.
Rā mē swaram.—The supply continued to be in good order.
Salem.— In April 1923, the filtered water showed little or no improvement over the raw
water. In October on the other hand the sand filters were found to be functioning properly.
A smell of H2 S was, however, noticed in the filtered water chamber.
Tanjore.— The supply to this town was just passable during the period under report.
Tirupati.—The supply was in good order on both the occasions. A slight deterioration
in quality was, however, noticed in certain parts of the distributary system.
Trichinopoly .—The gallery supply to this town was of fair quality during the year.
Tuticorin.— The supply of water from an irrigation tank without treatment of any sort
continues and the quality of the water is anything but satisfactory ; the necessity for
inaugurating a fully-protected supply has been constantly urged.
Vellore.— In May the sand filters brought about little or no improvement in the quality
of the raw water, but in November 1923 they were found to give some improvement in the
quality of the filtrate.
Vizagapatam.—In June the supply was just passable but in December, the samples
examined were quite unsatisfactory. Water from an excavation trench was used alterna--
tively in order to augment the town supply.
Vizianagram.—The gallery supply to this town was in fair order ; but deterioration in
the distributory system was, as the result of a fouled pipe line, found to occur.
Jails.
Bellary .—The water of the well supplying the Bellary Jail gave evidence of excessive
organic and bacterial pollution on each of the three occasions on which it was examined.
Systematic chlorination was recommended as necessary to render the water safe for drinking
purposes.
Berhampur .—The sample drawn in May 1923 from a tap on the Municipal main, supply--
ing the jail, showed deterioration in quality as compared with the sample taken at the source.
The necessity for periodically flushing out the pipe line was pointed out. In October the
water-supply was in good order.
Cannanore .—The water-supply to this jail was on the whole satisfactory during the year
under report.
Coimbatore.— In August 1923, the examination of a sample, said to be chlorinated,
showed that the treatment used was not efficient.
In February a sample was received which was so much overchlorinated as to smell
strongly of chlorine. Probably bleaching powder was added to the sample in the bottle.
The attention of the Inspector-General of Prisons was invited to this state of affairs.
Cuddalore.— In May the supply just passed muster, while in December the lake water
showed evidence of excessive bacterial pollution. Systematic daily bactericidal treatment
was recommended.
Palamcottah.— The water-supply to this jail was found on both the occasions on which
it was examined to be grossly polluted. Systematic chlorination was recommended.
