Where requested, the calculated readings from these samples were
supplied to the Department of Scientific and Industrial Research.
Water
The resident population of 85,840 in some 30,800 dwellings receive
water from the Metropolitan Water Board's mains or from deep wells.
At 31st December, 1964, 75 deep wells were in use. From 68 of these
wells the water is used for domestic purposes. Of the remainder, six
are used for standby only and one in case of fire.
During the year the use of one well situated at the Stag Brewery Site,
Allington Street, S.W.I, was discontinued; this well had previously
served Watney's Brewery.
During 1964, 77 samples of water from wells in the City were submitted
for examination; satisfactory reports were received of 60 bacteriological
examinations and 17 chemical analyses.
Public Swimming Baths
(I am indebted to the Director of Public Cleansing for the following
information.)
The City Council has three public baths establishments at Buckingham
Palace Road and Marshall Street (each having two swimming pools)
and at Great Smith Street, where there is one pool.
The water for each of these swimming pools is supplied by the
Metropolitan Water Board and is continuously heated, filtered and
chlorinated at a rate of 25,000-0,000 gallons per hour, the whole of
the water of any one pool being filtered and chemically treated in
four hours.
Fully automatic chlorine residual controllers and recorders, which
adjust the chlorine content of the water to the requirements of the
bathing load, are in use at both the Buckingham Palace Road and
Marshall Street Baths and were the first of their kind to be used in any
public baths in Great Britain.
Up to 31st August, 1963, an independent firm of analytical chemists
took samples (without notice) of water from the swimming pools each
fortnight. From 1st September, 1963, this work has been undertaken by
the public health inspectors in the course of their routine duties. The
