ENVIRONMENTAL HEALTH.
1. WATER SUPPLY.
The whole area is served by the Metropolitan Water Board through
a piped main supply. The service is satisfactory in quantity and
quality, no houses in the district are supplied permanently from
standpipes, there is no added fluoride, the natural content is 0.20
milligrammes per litre, the water is not plumbo solvent. Regular
chemical and bacteriological examinations are carried out by their
Water examination Department but in addition to this on 29 occasions
samples were taken from private houses, shops, schools, nurseries
and 23 samples were satisfactory.
Repeat samples were taken when reports were not entirely satisfactory.
Uncovered storage tanks in roof spaces can result in
contamination of water and this is particularly likely should birds
have access.
2. SWIMMING BATHS.
(a) Public. The Corporation's indoor swimming baths are
situated in Denmark Road, Kingston upon Thames and comprise two pools,
one of which is in use throughout the year, whilst the other is used
for swimming during the summer months, and in the winter season is
converted for use as a hall for concerts, dancing and other purposes.
In addition there is an instructional pool.
The baths are equipped with pressure filters and sterilization
is effected by breakpoint chlorination. Apart from regular pool-side
tests of the chemical condition of the water, 106 samples were taken
during the year for bacteriological examination of which 105 were
reported satisfactory.
The Surbiton Lagoon, situated in Raeburn Avenue, Surbiton, is an
open air pool 165 feet long, the water being treated by continuous
pressure sand filtration and breakpoint chlorination. Apart from
chemical tests 21 samples were taken for bacteriological examination
all of which were satisfactory.
