SYNOPSIS OF REPORTS ON INDIVIDUAL WATER SUPPLIES.
Municipalities.
A.dōni.—Samples were drawn in April and October. The water of the Ramjella Spring
was as usual satisfactory. The tank water showed evidence of excessive organic and
bacterial pollution. The slow sand filters were found to be working badly on both occasions.
The Municipal Council has been asked by Government to report on the possibility of their
introducing the improvements suggested by the Sanitary Engineer.
Berhampur.— The raw water of the tank contains organic matter in slight excess. In
April the filters produced only a slight improvement in the quality of the water. In October
the results were satisfactory. There was a deterioration in the water in the distribution
system at the October examination. At the suggestion of the Institute the Municipal
supply was laid on to the Jail during the year.
Bezwada.—On both occasions on which this supply was examined, an excess of free
ammonia was noticed in the sample drawn from a tap in the pumping station. The supply
was otherwise in fairly good order at the head works. Deterioration in transit was however
noticed on both the occasions. Special samples were drawn from the scour valves in
pursuance of Local Self-Government Memo. No. 242265-2, P.H., dated 23rd November 1922.
These samples showed excessive figures for bacterial and organic pollution. The brown
deposit in these samples was found to contain iron in the ferric state probably due to rust
derived from the pipes. No iron bacteria were found and iron was not present in solution.
Chidambaram .—The raw water of the tank is rich in organic matter. On both the
occasions on which this supply was examined no improvement was effected by the mechanical
filters. In June too small a dose of alum was being used and in December it was found that
no alum was being added prior to filtration. The pressure filter as it was worked at that
time was causing a definite deterioration in the water. The necessity for a thorough investi

concerned.
Cocanada.—In June 1922 the sample of the water derived from the slow sand filters was
found to be worse than the raw water. In December no appreciable improvement was
noted.
Conjeeveram.—In April the water at the source was found to be good but gradually
deteriorated in transit after the service reservoir as a result of a fouled or leaky pipe-line.
In October the supply was in very good order.
Coonoor.—The water supply to this Hill station was not satisfactory at the August
examination but was found to have improved in February 1923.
Cuddapah.—In July the water which was fair at the source, was found to deteriorate as
a result of storage in a dirty service reservoir. In January the supply was in fair order.
Dindigul.—In May the supply was satisfactory but in November deterioration was found
to occur in transit evidently due to a dirty condition of the pipe line.
Ellore.—The water supply to this station still continues to be unsatisfactory. In August
1922 slow sand filtration effected practically little or no improvement in the quality of the
water. A definite increase in the free ammonia content was noticed at this time. The water
was discoloured and opaque in the distribution system. In February 1923 very little
improvement was noted.
Erode.— The proper dose of alum was not being used with the filters with the result that
the supply continued to be unsatisfactory. The question of using the proper dosage of alum
has always been and still continues to be the most urgent problem with regard to the Erode
water-supply. This has frequently been pointed out to the authorities concerned.

but was found to have suffered considerably in transit owing to a dirty condition of the
distribution system. The same state of affairs has been recorded in previous years.
Guntūr.—On both occasions the water-supply was unsatisfactory.
Kodaikānal.—Owing to the absence of adequate facilities for transport of the sample
taker to and from Kodaikānal Hills, Government ordered the examination of this supply to be
restricted to once a year. No samples were collected during the year under report.
Kumbakonam.—The water-supply to this station which is derived from a sub-artesian
bore hole, showed, as usual, absence of lactose fermenters in 60 c.cs. on both the occasions.
The free ammonia which is evidently derived from the strata continues to be very high.
Kurnool.—During the year under report the sand filters yielded a satisfactory filtrate.
Slight deterioration, however, was noticed in the pipe line on both the occasions.
