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, one
of which was opened during the year; 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 76 slipper baths is provided.
Children's paddling pools are sited in a number of Council parks.
The new covered swimming bath providing facilities up to regional competition
standards, was opened at Winchmore Hill Road, Southgate. The bath measuring
110 ft. x 42 ft. is equipped with the most up-to-date treatment plant and is the
first to be equipped with television cameras for scanning the underwater area of the
deep end of the pool. The popularity of the pool exceeded all expectations with
over 140,000 people attending the pool between the opening date of 21st August
and the end of the year.
Some early troubles with the automatic chlorinating plant caused a number
of complaints to be made to the Health Department concerning smarting of the
eyes, and adjustments to the plant were required.
All bathing water is subjected to regular chlorination. Automatic filtration and
chlorination plants are installed at the public baths. 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
29 tests made.
