118. In respect of the supply to the Hill District, this district is practically entirely dependent on the quantity of water pumped up at the Bonham Road Pumping Station day by day. Under these circumstances, should anything happen to the pumping machinery or rising main, the Peak and Hill District would be deprived of water pending the completion of repairs or renewals.
119. It cannot be considered satisfactory that a population of from 1,500 to 2,000 should thus "be liable of being entirely deprived of water, and I consider, to meet the present requirements of the Peak and Hill District, provision should be made to provide for the continuance of the water supply in the event of such contingencies as above referred to.
120. The present consumption in the Peak and Hill District is 40,000 gallons per diem, and I consider that the construction of a covered service reservoir to hold, say, 10 days supply or 400,000 gallons at a sufficient elevation to command the entire district is required.
PRESENT REQUIREMENTS.
121. Present Requirements.-Having seen that the maximum daily supply that can be relied upon during the dry season from the Pokfoolum and Taitam catchment areas and reservoirs and streams intercepted by the conduits is 2,700,000 gallons, assuming that the supply is constant during the whole of that period, I now propose to consider the present requirements of the City (including the floating population) and Hill Districts.
122. The following tabular statement shews the quantity of water distributed, omitting the Tai Hang and Wongneichong streams, the estimated population supplied, and the average rate of consump tion for all purposes per head per diem during the years 1892, 1893, 1894, 1895, viz., since the new 'distribution works were completed, and a supply of potable water for the first time in the history of
the Colony distributed to every part of the built area of the City and Hill District.

It must, however, be noted that, during the years 1893, 1894, and 1895, owing to the scarcity of water the intermittent supply was introduced.
123. The following tabular statement shews the number of days in the months during the whole of which the constant supply was maintained, the quantity of water distributed (omitting the Tai "Hang and Wongneichong streams), the estimated population supplied, and the average rate per head per diem during the period of constant supply.

124. The maximum consumption for all purposes occurs in the month of August and during the months of September to April, it is, as a rule, somewhat less, but for the purposes of this report it 'will be sufficient to consider the average daily quantity required throughout the year based on the
results obtained during the periods in which the constant supply was maintained.
It will be seen from the above tabular statement that this varied during the years 1892 to 1895 from 17.6 gallons per head per diem to 14.6 gallons per head per diem.
This quantity cannot be considered excessive especially when the extensive use of water for bathing by the European community is considered.
Indeed, judging from the results obtained in other cities and towns, it is not unlikely that, with 'the introduction of improved sanitation, this quantity will be exceeded, though it is hoped concur- rently with improved sanitation every possible check will be kept upon the waste and misuse of water.
