Samples were taken from these Baths on 40 occasions and
numerous other visits were made to check the chemical content of
the water.
The Surbiton Lagoon, situated in Raeburn Avenue, Surbiton,
is an open air pool 165 feet long and 90 feet wide, with a depth
of three to nine feet, There is also a paddling pool for small
children,,
The water is from Metropolitan Water Board mains and is
treated by continuous pressure sand filtration, sterilisation by
breakpoint chlorination and oxygenation over an ornamental cascade,
Periodical samples of water are taken by the Borough Engineer
and Surveyor and the plant is adjusted as necessary. In addition
samples were taken on four occasions by the Health and Welfare
Department for bacteriological examination all of which proved to be
satisfactory.
(b) School Pools, One private school has a small swimming
pool which is used only by scholars and staff. Sterilisation is by
hand dosing with chlorine and changes of water as necessary.
Samples were taken during the summer when this open air pool was in
use. These were satisfactory with the exception of one occasion
when the dosing had not been fully carried out at the time of inspection
but this was immediately rectified.
There are seven swimming pools with treatment plants at primary
schools. In addition to numerous pool-side tests, bacteriological
examinations were carried out on 62 occasions,
Chlorinators at three of these school plants were out of action
for part of the swimming season which meant resorting to hand dosing
of chlorine. This method is more difficult to control and called for
much more time being spent on supervision. An increased number of
samples were reported as containing coliform counts higher than
desirable due to this situation, the cause being insufficient
chlorination.
All school baths were kept under observation, advice was given
where necessary and the overall standard maintained was satisfactory.
