samples were taken from houses in various parts of the supply
area for bacteriological examination, all of which proved
satisfactory. The fluoride content of the various supplies is

The Borough is not supplied with water from any public
wells nor are there any private supplies providing domestic
water to the general public. The Public Health Inspectors

Baths
Strict supervision of the three public swimming baths within
the Borough, two of which are indoor of 120,000 gallons and
68,000 gallons capacity respectively and the Open Air Pool
having 250,000 gallons capacity, was maintained throughout
the year in order to ensure the safety of the water for swimming
purposes. The larger indoor bath and the Open Air Pool are
closed in winter. Regular sampling of the water supply is
made to ensure that the standard of purity required is obtained
by the use of continuous filtration and chlorination processes.
In all cases the analyses of the samples of water taken (13
from the indoor baths and 5 from the Open Air Pool) proved to
be satisfactory. Mains water is used in all baths.
