undermentioned:—
Supply Authority Square Estimated
Miles Population
for 7971
Croydon Corporation (Central and
northern part of the Borough) 17.0 218,780

The waters in supply are of good organic quality and moderately hard
in character. They have no plumbo-sotvent characteristics and the fluoride
content averages about one-sixth of a part per million. All houses are supplied
from mains and there are no standpipes for this purpose. In the Croydon
Uidertaking's area 94 chemical and 603 bacteriological samples of raw water
were tested, also 125 chemical and 1,547 bacteriological samples of water
going into supply. For results of consumer samples of water sent by the
Health Department to the Public Health Laboratory Service, see Appendix P 69.
SEWAGE DISPOSAL
This is now a function of the Greater London Council. It is understood
that the building of new sludge digestion tanks and other improvements at
the Beddington works to deal with problems which arose in previous years
are proceeding satisfactorily.
