from Yau Ma Tei Service Reservoir was lowered and a second outlet provided to Gascoigne Road. At Kowloon Tsai Service Reservoir the outlet was diverted round the new Lo Fu Ngam Housing site. New service reservoirs at Tai Po Road, Lai Chi Kok, Tsuen Wan and a balance tank at Kau Wa Keng were completed and put into service during the year.
Catchwaters
326. As a result of the exceptionally heavy rains experienced during the summer months many slips occurred in catchwaters, both on the Island and the Mainland. On the Island these were only of a minor nature and were all effectively cleared in a short time. More serious slips occurred in the Beacon Hill and Shing Mun catchwaters and resulted in considerable damage. Emergency repairs were carried out in the first instance, and during the winter months with the flow at a virtual minimum, permanent repairs were made and the opportunity taken to reconstruct some 8,000 ft. of the Beacon Hill Catchwater invert. A measuring flume was constructed and a flow recorder installed in that catchwater.
New Pumping Plant
327. Elliot Station. The pumping equipment ordered in 1953/54 was received, installed and put into service to supply the Peak and Mid-levels.
Kowloon Supply
328. The new 7 million gallon per day rapid gravity filters functioned satisfactorily throughout the year, and the new 5 million gallon service reservoir on the site of the old slow sand filters was completed and put into service. Part of the existing outlet main was enlarged to improve flow conditions, and the completion of this scheme resulted in a considerable improvement in the supply position particularly in the Sham Shui Po area.
Tsuen Wan Supply
329. The new 5 million gallon service reservoir was completed and the 24" outlet main laid to connect with the distribution system and bring the reservoir into service. The laying of 6,800 ft. of new 18" and 8,800 ft. of new 12" mains between the 61 and 91 milestones on the Castle Peak Road was completed, 15,000 ft. of 8" main was laid to supply factories in the new development area and the distribution system generally extended.
