P.W.E. Hongkong.
The new main consists of about 2,600 lin. ft. of 44" W.I. pipe and 2,500 lin. ft. of 54" W.I. pipe, the pipes being of specially heavy type to resist the very heavy pressure.
When putting in anchor blocks and piers on the new main, it was found necessary in some cases to renew the blocks and piers on the two existing mains.
There are now three mains available for pumping water to the Peak.

Owing to alterations being made to the main Shaukiwan Road at this point, laying in this direction was suspended.
Pipe laying was then commenced from the Shaukiwan end, and a distance of 2,900 lin. ft. was laid in the direction of the City before the above road alterations forced a suspension of the work. As a temporary measure until the road alterations are completed, a 3" W.I. pipe, 4,200 lin. ft. in length, has been laid connecting the ends of the new 8" main thus obviating the necessity of obtaining water from Messrs. Butterfield and Swire as has been necessary in previous years.

(a.) Engine House & Foundations.
(b.) Engine and Boiler,
A report on the tenders received for this plant, by Mr. William Fairley, Consulting Engineer to the Crown Agents, was received in July, and, after consideration, owing to the enormous cost, it was decided to get a tender for electrically driven plant for purposes of comparison.
A tender for the electrically driven plant was received from the English Electric Company through their Shanghai Representative and was so low in comparison with the steam plant tenders that it was decided to again submit the whole matter to the Crown Agents' Consulting Engineer for a full report. This report had not been received by the end of the year.
