PUBLIC SWIMMING BATHS (contd)
Entry to the pool from the dressing cubicle is via the toilets and
footbaths and into the pool by teak steps fitted into each corner.
The pool has a capacity of 109,000 gallons continuously filtered through
pressure sand filters at the rate of 20,000 gallons per hour, chlorinated and
heated to a temperature of 74°F. in summer and 78oF. in winter. Chemical
treatment of the pool is by Alumina Ferric and Sodium Carbonate. A Chlorine
content of 1.0 to 1.5 parts per million is maintained during trade, with a
P.H. value of 7.6. Back washing of filters is done by air agitation of sand
and washing through to waste by M.W.B. water from a main storage tank. The
pool is emptied and re-filled as conditions and analysis reports dictate.
M.W.B. water is used for all purposes.
Cleaning of the pool sides and bottom is carried out every morning
before opening and during the day as circumstances permit.
During the year 8 samples of water were taken from the bath and sent for
bacteriological examination and Chemical Analysis. Results received from
both laboratories showed the water to be satisfactory in every case.
