for Central London. An instrument for measuring smoke pollution is in
operation at the Town Hall. Daily readings are taken and the figures
obtained are in milligrams of solid matter per 100 cubic metres of
air.
Smoke Control Areas
Smoke Control Areas Nos.6,7 and 8 came into operation during the
year. The Council decided not to make any more smoke control orders
as the incorporation into the London Borough of Waltham Forest will
take place early next year, therefore no surveys were carried out
during the year.
Water Supply
The whole of the area is supplied by the Metropolitan Water Board
and the standard has been satisfactory both in quality and quantity.
Bacteriological and chemical examinations of supplies are carried out
by the Metropolitan Water Board. The Water supplied is not plumbo
solvent in action; no cases of lead contamination or other forms of
contamination have been found.
All the dwelling houses and the population in the area are
supplied direct from the water mains, by means of piped supplies to
the houses.
Verminous Premises
The number of dwelling houses reported to be infested with
vermin remains comparatively small.
Sixty-six rooms were disinfested and insecticides were issued,
free of charge, to twenty-four tenants.
Swimming Baths and Pools
There are two public swimming baths and three school swimming
baths within the Borough. The water used in these baths is obtained
from the Metropolitan Water Board mains and is recirculated and
treated by filtration plants consisting of pressure filters, chlorination
plants and, in some cases, aeration plants. The water in the
baths is changed as often as necessary, depending on the amount of
use.
Samples of water from all these baths are taken at frequent
intervals for both chemical and bacteriological examination. All
samples taken during the year indicated that the water was suitable
for bathing purposes.
