THE REPORT OF THE CHIEF PUBLIC HEALTH
INSPECTOR, Mr. E. S. HERBERT, IS CONTAINED
IN THE FOLLOWING SECTIONS C, D and E.
SECTION C. — SANITARY CIRCUMSTANCES
OF THE AREA.
1. Water Supply.
The drinking water supply in Richmond is made up, in part from
local wells and, in part, from the Metropolitan Water Board. The
origin and method of treatment of these supplies have been fully
reported in the past and remain unchanged. Frequent sampling ensures
that the purity of the water supply is maintained, and throughout
the year the sample results have shown a high standard of bacteriological
and chemical fitness. The drinking water supplies in the
district are not plumb-solvent and every dwelling house in the Borough
has a piped supply of water fit for human consumption.
The determination of radioactivity in the well water supplies of
the Borough was first carried out in 1959 when samples from each of
the five wells proved to be satisfactory. The examination was repeated
in 1960 and further samples have been taken in the past year, and in
all cases the samples have continued to show entirely satisfactory
results.
A river water supply is piped to Kew Gardens, allotments and to
many domestic gardens; the water is chlorinated as a precautionary
measure but it is not fit for drinking.
Table 17 gives information on the consumption of water in the
Borough and on the samples taken.
2. Swimming Pools.
There is only one public swimming pool in the Borough which
is the public baths establishment owned by the Council. The pool is
100 feet by 32 feet with a capacity of 96,000 gallons, the water supply
being from local wells and the Metropolitan Water Board. The water
is filtered by Candy pressure filters, giving a turnover of approximately
six hours, and sterilization is achieved by chlorine gas treatment.
Daily recordings are made of available and residual chlorine in
the water, the pH value, and the shallow and deep-end temperatures.
In addition, bacteriological samples of the water are taken each month,
and all during the year, have proved satisfactory.
