208. An appeal to save water was printed in leaflet form in English and Chinese and 50,000 copies distributed, either by House Service Inspectors or by being enclosed with water accounts. A publicity film was also made for showing at local cinemas.
209. Metered Services.
With the delivery of still more meters from the United Kingdom, it was possible to provide meters for all supplies, though not necessarily for individual floors.
REPAIRS AND MAINTENANCE.
210. Major repair works carried out during the year included the sealing of the leaking scour valve at the Jubilee Dam. Unfortunately, after the work was completed, it was found impossible to open the damaged valve and it had to be abandoned, with the result that although the leak is sealed, the scour pipe is no longer operative. Other items were the completion, with the assistance of the Port Works Office, of the repair to the cross-harbour mains by the replacement of joint covers and damaged bolts, and the replacement of the high-pressure valve chamber for the No. 3 Steam Pump at Tytam Tuk.
211. With the completion of the new Kowloon Depot, with its self-contained meter repair shop, the repair facilities were at last able to meet the demands, and by the end of the year, as many as 2,683 meters had been repaired in one month in the two workshops at Hong Kong and Kowloon. Altogether 17,021 meters were repaired in the workshops and 10,217 on site during the year.
212. At the main depot at Bullock Lane, further plant was installed temporarily in the existing workshop, including a heat treatment furnace, a 28"/32" Lang Lathe, an Edgewick Twist Drill Grinder, and two mobile Lincoln shield-arc welding generator sets. Designs were practically completed for a new workshop. During the year, the workshop carried out 931 orders, of which 837 were for waterworks. Of outside work, the inspection and overhaul of boilers in Government buildings continued, though at the end of the year, arrangements were made for the transfer of this work in the future to the Chief Electrical & Mechanical Engineer.
RENEWALS AND IMPROVEMENTS.
213. Eastern Filters Conversion. This scheme was completed by the dismantling of the 3 million gallons per day plant at Bowen Road and the installation of the fittings in the new Eastern structure to bring the capacity there up to a nominal 11 million gallons a day, but capable of overloading to 12 million when required. The whole of the water delivered through the Tytam tunnel is now filtered in the new Rapid Gravity Filters.
