Officers' Quarters, Land Office and Police Court at T'ai Pó. (C.S.O. {11}).

The Chairman explained that it was considered necessary to construct permanent buildings at T'ai Pó for the accommodation of the officers stationed there and for a Land Office and Police Court. The plan which be submitted, showed two 2-storied buildings-one, to contain the quarters, to be erected on the small island where the landing place is situated, and the other, to contain the Land Office and Police Court, on the mainland in the vicinity of the Police Station.

The estimated cost was as follows:-

Quarters, including servants' accommodation and stable, approach path, &c., $24,500 Land Office and Police Court,

Total,

32,000

$56,500

It was unanimously agreed to reconunend that both buildings be proceeded with.

City Water Works Extension-Tytam Tuk Scheme. (C.S.O. 18). The Chairman laid before the Committee a general plan, dated the 17th October, 1903, showing the works which it was proposed to undertake at once and which would form the first section of the scheme. He explained that the result of the last trial-well sunk on the site of the proposed large dam had been disappointing, the rock being found at a depth of about 60 feet instead of about 40 to 45 feet as indicated by all the previous trial works. It was therefore necessary to conduct further trial works both on that site and on others in the vicinity with the view of ascertaining whether a more favourable line could be found for the dam and, as it was evident that some very considerable period must elapse before this part of the scheme could be sufficiently advanced to be available for increasing the supply of water, it was considered advisable to proceed at once with a dam of moderate dimensions and capacity some distance up the valley.

The

It was therefore proposed to construct a dam on the site which was referred to in Mr. COOPER'S Report of the 9th May, 1896, as No. 4, but to increase the size of it so as to render it capable of con- taining 194 million gallons instead of 100 millions as specified in his report. Two pumping engines, each capable of raising 14 million gallons daily, had already been ordered and the proposed dam would afford a supply about sufficient to keep one engine steadily at work during the dry season. second engine was intended as a duplicate, to the brought into service when the other was stopped for overhaul and repairs. In addition to the water impounded by the proposed dam the yield of the streams flowing in the valley would be rendered available by the small dam which had already been constructed in connection with the temporary pumping engine now at work and from which the main to the large pumping engines would be laid.

The other items required to complete the first section of the scheme included the following:-

100-8.12.03.

(i). The construction of a pumping station near the head of Tytam Bay to contain the two

pumping engines already mentioned.

(ii). The construction of a new road contouring the lower part of the valley at an elevation of 130 to 150 feet above Ordnance Datum and then ascending to join the existing road near the new Byewash Reservoir.

(iii). The laying of a suction main from the small dam mentioned above to the permanent

pumping station referred to in (i).

(iv). The laying of a rising main from the permanent pumping station by way of the new

road to the gauge basin at the entrance to the Tytam Tunnel.
