School meals
Typical meals were analysed for fat, protein, carbohydrate, mineral content and calorific
value in order to ascertain that the standards aimed at were being provided by the kitchens.
The results showed a good approximation to the requirements of the various nutritional
factors for the age groups concerned.
Water supplies
Care is taken to ensure that the water supplies to Council establishments are of
satisfactory quality. In the majority of cases water is taken from a public supply, but 15
residential schools and other premises draw water from private wells. In these cases the
supply is chlorinated before use by means of automatic dosing apparatus and the water
supply is regularly examined.
Swimming baths
The Council has under its control 13 swimming baths for public use and 26 swimming
baths situated at schools and institutions. Of these 19 are sited outdoors and 20 indoors.
30 of the baths are equipped with complete purification plant, two with plant for gas
chlorination and circulation only, and seven are chemically treated by hand. It is the
Council's policy to equip all baths with complete purification plants and during the past
year two further complete purification plants were installed.
As an example of the efficiency of treatment, the figures obtained during the five months
summer season from 13 fully equipped public baths may be quoted. These baths are
filled with water from the Metropolitan Water Board mains and are emptied and refilled
only once a year. The weather during the summer of 1959 was very good, and the baths
were extensively used. During this period about 1,750,000 people used the baths, and on
several occasions bathing loads at a single bath reached 7,000 per day. The minimum
recorded clarity was 12 feet, whilst the maximum was 161 feet.

The incidence of coliform pollution was about 2 per cent. and was due to temporary
features such as plant breakdown which were speedily rectified. The results obtained are
considered satisfactory, particularly for the conditions appertaining during the summer of
1959.
