(vi). Suction Main.-The suction main is 2,416 yards in length, the pipes being the same as those used for the rising main. Two sets of sluice and air valves and two washouts have been provided on the suction main. The suction main is laid in a trench 2 feet 3 inches deep, the joints being run with lead, 1$\frac{3}{4}$" deep, after the insertion of a strand of yarn.
The cost of the works was as follows:
(i.) Storage Reservoir, $383,435.14
(ii.) Pumping Station -
Preparation of site and erection of Buildings,
Pumping engines and boilers (2 sets) $111,820.66
(iii) Road, $86,465.55
(iv.) Access Roads, $198,286.21
(v.) Rising Main. $154,507.57
(vi) Suction Main, $135,094.97
Miscellaneous Charges, $24,815.75
$896,139.64
The foregoing is exclusive of a sum of $142,025.44 spent on the temporary pumping plant, which was brought into operation on the 1st November, 1903, and dismantled in May, 1907, and on preliminary works, surveys, borings, well-sinking, &c., principally at the site of the proposed low-level dam.
1908. Estimates, $15,000.00 Total Estimates, ......... $862,000.00 1908. Expenditure, $13,692.81 Expenditure to 31/12/08, $1,038,165.0896. Miscellaneous Waterworks.—The following are the principal items of expenditure under this heading, representing in some cases only a part of the cost of the works in consequence of their execution extending over more than one year :-
(i.) New Service Reservoir at 750′ level, West Point, Construction of reservoir (capacity 448,000 gallons), completed, $11,544 Extending 8" rising main to do. completed, $11,945 (ii) New 8" rising main to 600′ service reservoir, West Point, Completed, $322 (iii.) Conduit Road Extension-6" main from 750′ service reservoir along Hatton and Conduit Roads, Queen's Gardens and May Road as far as Inland Lot 1772 (except the portion in front of Queen's Gardens houses which was laid in 1907), completed, $13,705 (iv.) Substituting 5″ rising main in Peak Road for old 3″ & 4″, $3,307 (v.) Laying 4" main in diverted portion of Shaukiwan Road past Shaukiwan Marine Lots 2-1, &c., completed, $1,130 $30,409 1908. Estimates, $33,500.00 1908. Expenditure, $30,852.34Item (i). This new reservoir, the reason for which was explained in last year's report, was completed and brought into use in August, but there was still a balance outstanding at the close of the year. Great improvement has been effected in the supply to the houses above Conduit Road and, in the event of fire occurring in this neighbourhood, an efficient supply of water should now be found available.
The reservoir is constructed principally of cement concrete, the walls being faced with brick in cement and the covering consisting of brick arches supported on brick pillars. Its capacity is about 418,000 gallons.
The district supplied from it comprises the whole of Conduit Road, Queen's Gardens, May Road and the group of houses on Peak Road above Queen's Gardens. The latter were formerly dependent upon a small tank of some 12,000 gallons capacity, which would have been found quite inadequate in the event of an outbreak of fire or of any serious breakdown in the pumping plant. On completion of the new reservoir, it became possible to dispense
