environment. With this aim, construction of submarine outfalls in Wan Chai and Lai Chi Kok was completed.
Sewerage systems are an integral part of the new towns being developed in the New Territories. A sewage screening plant is under construction for Castle Peak new town and consulting engineers have completed the design of the Shek Wu Hui pilot sewage treat- ment plant. When commissioned, the plant will improve the sanitary conditions in that area as well as providing information on the best form of sewage treatment to suit local conditions.
The extension of stormwater culverts in Central reclamation was completed, but is still in progress on the reclamation at Wan Chai. Remedial work to landslide areas in the Shau Kei Wan district and construction of the main culvert at Kwai Chung were completed. Work continued on three other projects, namely the river training at Sha Tin, the extension of two large culverts in the Kai Tak area and the intercepting sewer extension around Pillar Island.
PORT WORKS
With work well under way on three container berths at Kwai Chung, the construction of the necessary access roads and flyover was started so that these would be ready for the arrival of the first ships in the latter half of 1972. A contract for dredging the sea approaches to the berths was also let and this, when finished, will enable the largest container ships to tie up even at low tide. The planning of two further container-terminal lots was finalised together with the investigations required for selecting suitable borrow areas to provide filling material for the reclamation involved. Other work completed during the year included a pier at Aberdeen to serve both the Fisheries Office and the Marine Licensing Station, a passenger- ferry pier at Kwun Tong and a further 600 feet of seawall in Kowloon Bay and 250 feet at Cha Kwo Ling, both to retain reclamations.
In the New Territories, work was completed on improvements to the existing breakwater at Three Fathoms Cove, a new pier at Shek Pik on Lantau, a roof to the existing public pier at Tai O and a new spring-fendering system for Tsing Yi public pier. A reclamation to form land for new departmental quarters at Tai Po and naviga- tional beacons at Tai A Chau, Pun Shan Shek, Pak Kok Tsui, Gau Tau, Fan Lau and Yuen Kok were also completed. Dredging was carried out to deepen the approach channel to Tai O Creek and to improve and enlarge the anchorages at Chek Keng, Long Harbour and Sai Kung.
