322. Three miles of 15-inch pipeline were laid from Tai Lam Chung, work began on the access road and site formation for the service reservoir and filters and on construction of the pump house at Lam Tei started, and three and a half miles of 10-inch and 8-inch diameter distribution pipes were laid to link Yuen Long to Sek Kong.
Shek Pik Scheme
323. The test section of grouting in the foundations of the dam proved successful and it was decided to proceed with the full scheme. 324. Work started on access roads, staff quarters and other buildings, and the piling work forming part of the grout curtain cut-off to the dam progressed well. Negotiations for the resettlement of the villagers of Shek Pik and Fan Pui, whose present homes and fields must be cleared from the reservoir area, made slow but steady progress.
325. Survey work on the access roads and catchwaters began after survey camps had been set up. Sites selected included those for a pumping station and the rapid gravity filtration plant near Pui O on Lantao Island, a pumping station and balance tank at Sandy Bay on Hong Kong Island together with a 30-million gallon and a 5-million gallon service reservoir at Mount Davis to receive the water delivered from Lantao by submarine pipelines.
326. The survey for the underwater pipeline from Lantao to Hong Kong went to contract, and invitations for tenders for construction of the Shek Pik Dam, including the overflow spillway and diversion tunnel, went out on a world-wide basis.
Plover Cove and Hebe Haven Schemes
327. Last year's Report referred to the possible conversion of sea inlets into fresh water lakes. This led to two sites being investigated at Plover Cove and Hebe Haven. The proposals in both cases are similar and entail the construction of barriers or dams at the sea inlet and pumping out sea water, allowing the reservoir so formed to fill up with fresh water from the natural catchment and with water brought in by catchwater and tunnel from adjoining areas. The Consulting Engineers were asked to prepare feasibility reports on both these schemes, and their report on Plover Cove was completed during the year and is now being studied.
Irrigation Works
328. In addition to repairs to existing schemes necessitated by rainstorms, this office undertook a considerable amount of new work
