Page 196. In the meter repair workshops 23,941 meters were overhauled and tested and a further 8,765 meters were repaired on site, making a total of 32,706 repairs. This represents 93% of the total meters installed, which means that on the average meters are being overhauled about once a year.

Renewals and Improvements
Page 198. Red Hill Filters. These filters, referred to in paragraph 215 of last year's report, were completed and put into service. With a designed capacity of 600,000 gallons per day and provision for extension to 900,000 gallons the Stanley peninsula is now assured of an adequate supply. These filters provide for the first time in Hong Kong, for correction of pH value by the addition of lime after filtration. The total cost was $319,175.
Page 199. Bowen Road Service Reservoir. The site of the new service reservoir formerly contained filters and two small service reservoirs. The filters were removed last year and incorporated in the new Eastern Filters, leaving two small service reservoirs at different levels with a combined storage of only 1.12 million gallons. The head of water from the upper to the lower reservoir is used to drive hydraulically driven pumps discharging into Magazine Gap tank.
Page 200. The present scheme provides for a 5 million gallons service reservoir at a level roughly midway between the present reservoirs, to be supplied with water from Bowen Road. The head of water from Bowen Road will be sufficient to drive the hydraulic pumps when transferred to a new pump house at a level just above that of the new reservoir.
