million parts of water. Even when only one part of chlorine was
added to ten million parts of water, the reports from the analysts
were very good, but it is thought better to use more than this
quantity in order to ensure a safe supply at all times. Most of the
analyses are made after the water has been chlorinated, i.e. as it is
delivered to the public. The samples are taken either from the
wells, mains or taps in a private house. I have never yet had a
report on the chlorinated water which cast any doubt on the
purity. The chemical analyses have been good and the Bacteriological
examinations have always shown that there was no Bacillus
Coli in 100 c.c. and no Bacillus Enteritidis in 100 c.c. This is a
very high standard and the analyses can be considered very
satisfactory.
Workmen Employbd at the Works.
No member of the staff employed at the Works has had
Typhoid Fever. Workmen employed in the Wells are required to
wear rubber boots, well washed before entering the wells. This is
to prevent fouling of the well by the carrying in, for example,
excreta on their ordinary boots.
Other Precautions.
Great care must always be taken when dealing with a public
water supply and any activities likely to have an effect on the
supply must be closely watched.
Therefore, care has been taken at various times to control the
sanitary arrangements of camps, etc. by insisting that special
closets should be used and arrangements made to carry away from
the ground slop water which might otherwise find its way into the
soil.
Owing to the special character of the Borough's water supply,
such camps should not be encouraged.
