In connection with the swimming baths there has been provided
a most up-to-date filtration, aeration and chlorination plant
capable of purifying the contents of each bath every 3½ hours, thus
enabling bathers to use the baths with every confidence.
Regular chemical tests are taken (twice daily) and bacteriological
tests taken periodically.
A summary of Bacteriological Samples taken during the year, with the results of the examinations, is given in the following table, particulars of which were communicated to the Adoptive Acts Committee and the Baths Superintendent at the time of receipt of the Reports:—
