equitable than in the corresponding periods of the previous year. The most difficult supply areas on the Island continued to be the congested districts in North Point, Shaukiwan, Central and Western. Improvements continued to be effected by the relaying and the enlargement of a considerable number of distribution mains.
222. On the Mainland the Shamshuipo Balance Tank, referred to in last year's report as the Kowloon Tong Balance Tank, was put back into service and the supply to the Shamshuipo District was improved. In the southern part of Mongkok and the northern part of Yaumati, both districts being at the extreme end of a distribution system, a large programme of relaying and enlarging of the distribution mains was carried out and showed gratifying results. The number of complaints was reduced considerably and those which were received were distributed more or less evenly over the whole peninsula.
223. Filtration. The amount of water available for distribution even with the reservoirs overflowing was again restricted owing to inadequate filtration capacity. It was not possible to increase this during the period under review, but survey work was completed and an order placed for a modern 7 million gallons per day Rapid Gravity Filtration plant to replace the obsolete and inadequate 4 million gallons per day slow sand filters at Taipo Road and for a new 2 million gallons per day R.G. Plant for the Tytam-Shaukiwan supply.
Temporary arrangements were well in hand towards the close of the year to re-commission the disused slow sand filters at Eastern, the site of which is to be used later for a much needed new service reservoir.
224. Water Analyses. The purity of the water was maintained at a reasonably high standard and no contamination in the main distribution system was recorded. Sampling and testing for Bacteriological and Chemical purity were carried out regularly as in previous years by the Government Pathologist and Chemist respectively. Samples were taken at all stages from the raw water stage to the water at consumers' taps.
