(b.) A short length of sewer in Barker Road from Victoria Hospital to Lyeemun.

The estimated cost of this work is $1,000.

(c.) A sewer laid from the present outfall at Wanchai Gap to a point in the Valley east of Bennetts Hill about 600 feet North of the main road to Deep Water Bay.

The estimated cost of this sewer is $24,000.

2. The existing sewers are in good condition and are of sufficient capacity to deal with a Water Carriage System extended to the whole of the Peak District. The present maximum daily consumption of water in the Peak is

...133,000 gallons

and I estimate the additional consumption, if water closets are installed in the whole of the Peak area west of Wanchai Gap, exclusive of Mount Nicholson, which loes not affect the existing sewers, at about Allowing for future increase in this area. say

to be disposed of by the Peak, Barker, Craigmin and Coombe Road sewers, which are capable of dealing with more than 6 times the D.W.F. to which each would be subject before the overflows came into operation.

3. This sewer might be laid on the lines mentioned in 1 (b) of my minute to you dated 30th March, 1921. In addition, it would also be capable of dealing with the drainage of any houses built on the Northern slopes of Mounts Nicholson, and Cameron, above the level of Wanchai Gap. With the increased volume of sewage involved by taking in additional Peak areas I would suggest that the sewer be continued along the Deep Water Bay Road to a point of outfall where there is a strong current in deep water about 400 yards West of the Aberdeen Paper Mills. I estimate the cost of this work at $25,000 and the sum total of the whole scheme at $55,000.

Mr. NEWHOUSE,

Will you please supply for the information of the Water Carriage Extension Committee:-

(1) an estimate of the cost of construction and reconstruction of sewers required to deal with all drainage between the 400 and 750′ contours on the lines suggested in your report dated 30th March, 1921.

(2) whether the existing sewers are sufficient to deal with a water carriage system in this area, and, if not, what additional cost would have to be incurred.
