In addition to the above several accounts were prepared in connection with work carried out by the drainage office. There were also the usual accounts for fees for disconnecting traps on Crown Land.
Accounts for shoring and other work due from owners of private properties or their contractors were dealt with in the usual manner.
29. Improvements etc., to Public Streets.—The policy of requiring houses, when undergoing reconstruction, to be built at a higher level where necessary in order to provide for the future raising of certain low-lying areas in Hong Kong and Kowloon has been continued. In some cases, arrangements were made allowing the ground floors to be retained at their existing levels upon owners giving an undertaking to raise such floors when the raising of the street is carried out.
30. Footways.—Attention has been given under Section 134 of the P. H. & B. O. (clause 11 of Schedule G) to footways under verandahs and balconies, any necessary repairs being carried out by this Department at the cost of the owners of the property from which such verandahs and balconies project.
31. Typhoon and Rainstorm Damages.—The exceptional rainfall during the months of June and July resulted in considerable damage to property. In June a retaining wall erected on the East side of I.L. 2354, Stubbs Road, to support spoil gave way, causing damage to other private property below the site, and a very large quantity of debris etc., was washed across the Wongneichong Road on to Happy Valley. Two persons were killed.
In June further damage was caused by flooding in the vicinity of Wongneichong Village; roofs, flank, front and rear walls of fifteen houses collapsed or were otherwise rendered dangerous, but no casualties were reported. Further damage was done by floods in July, when certain of the village houses collapsed. No casualties were reported.

(e). North and South Tunnels and South Conduit.
North Tunnel.-—Operation was commenced in April at its South end and at the close of the year a length of 1,043 feet has been driven under the Smuggler’s Ridge.
— Q 135 — P.W.E. New Territories.
It was found necessary to line several short lengths with cement concrete of a minimum thickness of 12 inches at distances of 291 to 304, 419 1/2 to 461, and 554 to 627 feet from the Tunnel portal.
The rock met with was mostly granite of varying hardness with instrusions of soft green stone.
In December a start was made with the excavation of the open cut approach to the North end of this Tunnel.
South Conduit.—This work was nearing completion at the end of the year. Owing to the poor nature of the foundations more work than was anticipated had to be undertaken at the main stream crossing near the North Tunnel
South Tunnel.—Operation was commenced at the North end in February and at the South end in April. By the end of the year a length of 1,327 feet has been driven from the North end while another length of 1,143 feet has been pierced from the South end. Granite of a good quality was found throughout and no lining so far has been found necessary.
A length of 884 feet of cement concrete invert has been laid up to 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, 12 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.

An 18 inch diameter draw-off pipe has been provided, with 12 inch control valves.
A covered gauge basin has been constructed with 15 inch connections to the Kowloon Supply and the projected Shing Mun trunk mains. The connecting main, live hundred feet in length, of 15 inch C.I. pipes was also laid.
The top water level of this Reservoir is 275.00 A.O.D. and the depth when full is eighteen feet three inches, its capacity being 1.547 million gallons.

These two works are being carried out together under one Contract, No. 12 of 1921 and the Department is in charge of the whole of the work which, in addition to the Government’s share under sub-heads (a) and (b), includes the whole of the work of Reclamation for all the Participants under the Praya East Reclamation Ordinance No. 17 of 1921, with the exception of raising drains and sewers behind the Reclamation proper, the formation of roads and surface water channels and connections, etc., which works are being carried out by the Public Works Department.
The Government’s Contribution under (a) amounts to approximately 18% of the total cost of the Reclamation, the remaining Participants finding the balance of the Funds necessary for carrying out the work.

(i) The filling for the Reclamation, referred to in paragraph 2 of Annexe L to the Report of the Director of Public Works for 1924, is being obtained by the demolition of Morrison Hill. Early in the year it was realised that, owing to the quantity of rock then being exposed in the hill proving to be much greater than was originally anticipated, the Contractor could not be expected to carry, on the work at his prices which were tendered on the assumption that the excavation in the hill would be mostly soft material. Government, therefore, appointed a Committee of Engineers, consisting of the Port Engineer and his Deputy, and two other independent engineers, to examine the situation and report as to the best means of settling the deadlock, with the result that no stoppage occurred, but that from March 31st, the Contractor should in future be paid a bonus percentage on the whole of the Contract conditional on certain progress in the filling to the Reclamation being maintained, month by month, for the remaining period of the contract which was extended by 15 months, until 31st January, 1929.
(ii) Sea Wall.—Dredging was continued throughout the year on the trench for the wall, a further length of 347'-6" ( F1 to F2 finally sounded 20.7.25) of trench being completed, and a further length of approximately 1,251 feet was filled in with pell-mell rubble. Concrete blocks for the foundation of the sea wall were laid for a further length of 1,637 feet and 1,459 lin. feet more of wall was built. Two sets of boat-landing steps were built, and 1,241 lin. feet of coping set. Pending the completion of reinforced concrete pier No. 2, a temporary bamboo pier was built and maintained for the purpose of supplying water to the Waterboat Companies.
The construction of the necessary culverts for sewerage through areas already reclaimed was proceeded with, and in one case the new sewer was put into service; others are ready for service whenever the sewers behind the new Reclamation are raised.
(iii) The aggregate area of Reclamation approximately formed by the end of the year amounted to 44 acres being an addition of 8 acres during the year. Of the total area reclaimed about 11 acres were brought up to finished level, ready for the formation of roadways by the Public Works Department, when the lots thereon can be handed over to their rightful owners.
As a result of the labour troubles which commenced about the end of June, considerable delay was caused to the work generally, and for about a month practically no work was done.
The retaining wall to the North side of Gap Road between the Monument and Stubbs Road was completed as was also a short length of curved retaining wall to allow for easing the turn from Gap Road to Stubbs Road.
Morrison Hill was attacked from a fresh point on the North side, at the Wanchai Road level, by running a gullet into the hillside over the line of the twin storm-water culverts. Excavation was removed from this point by Decauville wagons to a tip on the site of Godown No. 142, from whence it was transported to the Reclamation at formation level.

Revenue.—Pending development of the areas which become available, it is the practice to permit such area's of reclaimed land to be occupied at competitive rentals, under Licence, and the fees collected in respect of these licences during the year under review amounted to $30,231.80 which was credited to the reclamation fund.
