Only two such bakehouses were in use. The existing Certificate of
Suitability was continued in operation for a further five years in one
case. In the other, notice was given that the Certificate would cease
to have effect and the bakehouse is now closed.
COMMON LODGING HOUSES.—There is one common lodging
house in the Borough which provides sixty-nine beds for women.
WATER SUPPLY.—All drinking water in the Borough is supplied
from the Metropolitan Water Board's mains and has been
satisfactory. E. Windle Taylor, M.A., M.D., D.P.H., the Director
of Water Examination of the Metropolitan Water Board has kindly
supplied the following information and figures:—
"The water supply to your Borough has been of satisfactory
hygienic quality and adequate in quantity during the year 1959.
It is derived from the non-tidal portion of the river Thames, stored
in the Board's reservoirs at Staines and Littleton and filtered and
chlorinated at the Board's works at Ashford Common and Barn
Elms. The Board's waters are not plumbo-solvent.
Samples are collected at each stage of the purification process
and in the distribution system daily and immediate action is taken
in respect of any form of contamination or of any variation in
quality. All repaired mains are disinfected with chlorine before
being returned to service.
Preliminary calculations indicate that the average consumption
for the whole of the Board's area during 1959 was three hundred
and fifty-one million gallons daily".
