"Swimming Pools (Open Air)
Bathing facilities are provided at three Open Air Pools, during the summer period,
within the Borough, each of these properties being owned by the Council. The water
capacity of each of the Pools is as follows:
Twickenham Open Air Pool 280,000 gallons
Hampton Open Air Pool 206,000 gallons
Teddington Open Air Pool 180,000 gallons
this water being supplied by the Metropolitan Water Board. The pools' water is
filtered through pressure sand filters and sterilized by chlorine gas treatment operating
on the "marginal" principle. The pool water at the Twickenham and Teddington
Pools is turned over once every 6½ hours, whilst that at the Hampton Pool operates on
a 4 hour turnover rate.
Colourmetric tests and water samples at each pool are taken three times daily to
determine free-available/residual chlorine content of the water, the pH values of the
same, and both shallow and deep end water temperatures. Each of the results obtained
are recorded in a standard log-book.
Bacteriological tests of the water at each of the above pools and including Rich'
mond Baths are made monthly and, during the past year 78 samples have been taken,
of which 62 were satisfactory and, whilst the remaining 16 were below the recommended
standard, repeat samples in each case have produced satisfactory results. The
drop in the number of tests taken during 1968 (60 samples) compared to the number
of tests taken during 1967 (104 samples), reflects the closing of the Richmond Baths
from the 19th February to the 25th May, 1968 inclusive, due to essential major repairs
to the ceiling over the main pool and Learners Pool. (See page 58 — Water Supply).
Richmond Baths (Indoor and Open Air)
The new Richmond Baths Establishment, of a "combination" nature, situated in
the Old Deer Park, Richmond, was opened to the public in August, 1966.
The establishment consists of one main Indoor Pool 110' x 42', water capacity of
210,000 gallons and a turnover rate of 3 hours; one Indoor Learner's pool 42' x 24',
water capacity of 17,000 gallons and a turnover rate of 1½ hours, and an, Open Air
pool 110' x 42', water capacity of 160,000 gallons and a turnover rate of 4 hours. The
filtration of all pools' water is through Pre-coat filters, and sterilization is carried out
by chlorine gas treatment on "breakpoint" principle. A system of pool water sampling
and testing is installed and all records are recorded automatically on graphs. A plenum
heating system is installed and the whole establishment is operated electrically utilising
"off-peak" electricity.
The private baths suite consists of 12 private baths for both ladies and gentlemen
respectively together with the necessary waiting rooms, toilets, etc.
The grounds are landscaped and well laid out and provide some two acres of grass
and banked areas which are available for sunbathing, games, etc."
