WATER SUPPLY
The water supply of the District is provided by The Sutton
District Water Company and The East Surrey Water Company
from deep wells or borings in the chalk.
The water is softened and chlorinated and all houses in the
District are provided with a direct supply which was satisfactory
in quality and quantity during the year.
The natural fluoride content of the water was 0.13 to 0.15
parts per million supplied by both companies.
There are no private wells in the District with the exception
of the one at Cane Hill Hospital which is used to supplement the
public supply.
Routine samples of the treated water in public supply were
submitted quarterly for bacteriological and chemical examination.
In all, 25 samples were taken for bacteriological examination and
8 samples for chemical examination with satisfactory results in
each case.
No samples of raw water were submitted by the department
for bacteriological examination.
In addition, both the Water Companies and Local Authorities
sharing these public supplies provided the department with copies
of reports on the samples taken by them of the treated water in
public supply.
Fifty-two samples were taken from the supplies of the two
Companies and examined for hardness by the department. All
of these were satisfactory in that adequate softening had been
carried out as required.
The private supply at Cane Hill Hospital which is chlorinated
is kept under supervision and sampled regularly by the Public
Health Department of the London County Council. Copies of
reports on the samples taken are submitted to the department for
information.
