128. Water Supply to Aplichau.-This work was referred to in paragraph 127 of last year's Report.
The work comprised the laying of a 2" Steel flanged main on the bed of Aberdeen Harbour to convey water from the 3′′ main on the Island Road at Aberdeen to Aplichau Island.
Special flanged W.I. Pipes of 2" internal diameter in lengths of 20 feet were joined up on shore into sections 140 feet long, at one end of which a special ball and socket joint was fixed to take up the inequalities of the harbour bottom. These 140 feet sections were floated out into position attached to sampans, joined up on the surface, and lowered to the bottom, section by section, an examination of the pipe when laid being made by a diver. The length of this section was 540 feet.
