The increased quantity of raw water pumping can be largely attributed to the greater quantities received from the Sham Chun Reservoir.
Waste Detection
10.14. Waste detection covered the detection of leaks, and repairs to valves, house connexions and the distribution system, as well as investigations of high consumptions, unauthorized usage of water, etc. Though waste detection procedure, which is water consuming, was to some extent restricted by the shortage of water, 34 of the 93 waste detection areas were examined and tested, and an estimated saving of 6,040 gallons per hour was achieved by the repairs effected.
Metered Services
10.15. The following table gives the position over the last three years:

Workshops
10.16. 1,960 separate items of work, including 39 orders from other departments, were carried out. This work at times fully committed the resources of the workshops, with the result that 48 orders had to be executed under contract by local firms.
10.17. 46,489 meters were overhauled, representing 50.5% of all meters in service.
Distribution and Mainlaying
10.18. Work continued on extensions to serve new developments, replacement of defective pipes, enlargements of under-sized mains, and alterations necessitated by road re-construction.
