1925 Expenditure, $60.00
Total Estimates, ...$200,000.00 Expenditure to 31.12.25, $60.00
(h). Pipe Line.-A Contract for £26,043. 12. 3. was let to Messrs. Stewart & Lloyds in England for the supply of the necessary 24 inch diameter steel pipes and specials.
At the end of the year two specimen pipes sent in advance for test purposes were received in the Colony. A further Contract for £407. 14. 0. was let to Messrs. Glenfield & Kennedy, Ltd., for the supply of the necessary valves which were delivered in the Colony in October.
A local Contract for the construction of a piled reinforced concrete culvert under the Railway was prepared, but was not let at the close of the year.

(i). Piper's Hill Service Reservoir. This work was referred to in paragraphs 189 and 213 of last year's Report.
Excellent progress was maintained and the work was satisfactorily completed and tested by the end of the year.
It was constructed throughout of cement concrete, the walls being of gravity section, except where a reduction in thickness was found possible in cuttings. The invert is of cement concrete 8-1/2 inches in thickness, and was laid in approximately 12′ x 12' squares with bitumen expansion joints. The quantity of cement concrete used was 3,614 c. yds.
The roof, which is of jack arching and carried on reinforced concrete beams, is supported by 15" x 15" reinforced concrete piers.
A division wall of gravity section, 13.5 feet in height, is provided so that one-half of the reservoir may be put out of action for cleaning, &c., without disturbance to the other half.
