of a contract for laying the pipes, a start was made on the dredging of a trench in the seabed for their protection.
355. Delivery of the pipes in unprotected lengths of 27 feet commenced.
356. A contract was let for the site formation of the balance tank and pumping station at Sandy Bay. Site excavation for the 30-million-gallon service reservoir on Mt. Davis continued, although the anticipated rate of progress was not attained.
357. Investigations of the site for the 6-million-gallon service reservoir at Kennedy Town were completed.
358. After reaching agreement on the route to be taken by the trunk mains from Mt. Davis to Central District, approximately 9,200 feet of 24" steel main was laid in Bowen Road.
Plover Cove and Hebe Haven Integrated Scheme
359. A preliminary contract let for this scheme included:
(1) site investigation along the proposed line of the dam in Plover Cove; (2) the construction of a test mound to decide on the materials required to form the dam embankment;
(3) boring and drilling along the proposed tunnel lines and at the sites of the subsidiary dams;
(4) boring to decide the location of suitable materials for the construction of the dam.
360. After encountering various difficulties and sinking many bores to much greater depths than had been expected it was finally concluded that the sites provisionally chosen for the subsidiary dams were unsatisfactory.
361. A contract was completed for the site investigation along the proposed line of the dam at Hebe Haven, but the difficulties experienced with the uncompleted first contract at Plover Cove resulted in the submission of the final report being delayed.
362. It became evident that before either the Hebe Haven or Plover Cove Reservoirs could come into production, it would be possible to start work on part of the scheme and make available within three to three and a half years' time a useful addition to the water supply. Approval was therefore obtained to commence the following works estimated to cost $100 million:
(1) service reservoirs above the Kowloon Foothills Roads and a mile long tunnel under Lion Rock;
(2) stage I of the Plover Cove treatment works, with a capacity of 60 million gallons a day;
