under review and all conformed to standards of purity considered suitable for public
supply.

BATHS, WASHHOUSES, BATHING PLACES, ETC.
Provisions exist under Part VIII of the Public Health Act, 1936, for the provision
and control of baths, washhouses and bathing places by local authorities.
The council provides three open-air and three covered swimming pools for
the general public, a swimming pool for the exclusive use of school children, and
four swimming pools situated within school premises.
At three of the public swimming pools a total of 75 slipper baths is provided.
Children's paddling pools are sited in a number of council parks.
All bathing water is subjected to regular chlorination. Automatic filtration
and chlorination plants are installed at the public baths, at the swimming pool used
exclusively by school children and at two of the school pools. Water supply is
from the public water mains except for a school swimming pool supplied by a deep
well.
Bathing water samples are tested at regular intervals during the day for free
chlorine, the presence of which is indicative of the effectiveness of the dosage.
Samples are also regularly submitted for bacteriological examination and chemical
analysis. The results of these examinations were satisfactory in all but one of the
51 samples tested.
Even the presence of small numbers of organisms makes a sample unsatisfactory
when judged by the high standard of purification as demanded in drinking water.
Such was the case with the one unsatisfactory sample. However, the chlorine dosage
was increased and all later samples were satisfactory.
The total attendance at the public swimming pools during the year was 826,291,
an increase of 192,653 over the previous year.
