Composting Factory at Tsun Wan Berthing Facilities Required.

In the plan attached to P.W.D. memorandum 7121/51

of 16th June, 1951, to you, provision is only made for two 98 foot berths for unloading along the 700 feet of sea wall. It occurred to me that this would almost certainly be inadequate for the unloading of the Sanitary Department's refuse and nightsoil barge fleet or would necessitate an extremely rapid rate of discharge which could only be achieved by very costly machinery. I had a precast made of the times at which refuse and nightsoil barges would arrive at Tsun Wan and at which, they would require to leave and then asked Hon. D.P.W. and Director of Marine for their advice. I attach copies of (a) my memorandum S.D. 482/49 of 12th July to Hon. D.P.W. and Director of Marine; (b) of Hon. D. P.W.'s memorandum PWD 2906/50 of 25th July in reply to (a); (c) of Director of Marine's memorandum MD 565/1950 of 27th July in reply to (a).

2.

The consensus of opinion seems to be that at least three berths will be necessary for refuse barges at Tsun Wan and possibly also a pier at which two nightsoil barges could discharge by pump simultaneously. Hon. D.P.W. considers that it will be necessary to lay mooring buoys in addition to accommodate barges awaiting their turn to discharge alongside the wall. I assume that this means that an additional tug will be required to stand by off the installation to move barges into position and Director of Marine points out that this would entail additional capital expenditure of $350,000 to $400,000. His suggestion that dolphins should be built along the whole length of the wall and barges hand hauled to discharge points as required might be cheaper.

3. The correspondence is of interest as showing the factors which will have to be taken into consideration in the planning and I recommend that a copy of all three documents should be forwarded by you to Mr. Brunt to assist him in his preliminary layout of unloading facilities. I understand that Director of Marine considers that considerable difficulty may be experienced in the designing and use of containers in the refuse barges but it is essential that some means be found for rapid unloading.
