65. Maintenance of City and Hill District Water Works.- The year opened with a full supply in all districts, but owing to the previous rainy season being a late one no restrictions became necessary until May 5th, when the depletion of the Pokfulam Reservoir necessitated a restricted supply in the district West of Eastern Street.
From 7th to 23rd May all the Rider Main Districts were put on a restricted supply.
From 25th June to 2nd July all the districts were again put on a restricted supply, owing to the temporary flumes at Bowen Road being damaged by a landslide.
From May 24th to the end of the year a constant supply was maintained in the districts East of Eastern Street. At the West of Eastern Street, however, it was only possible to give a restricted supply due to the muddy state of the Pokfulam Reservoir consequent on the washing down of large quantities of detritus from the new Peak Motor Road.
The reconstruction of the Bowen Road Conduit, arising out of last year's landslide near the Military Hospital, was satisfactorily completed, and water flowed through the new section on August 29th.
The total quantity of water stored in the impounding reservoirs on the 1st January amounted to 1,812 million gallons, there being 415 million gallons in the gravitation reservoirs and 1,397 million gallons in the low-level reservoirs requiring pumping. Storage reached a minimum on the 15th May when the total was 916 million gallons, there being 171 million gallons in the gravitation reservoirs.
The reservoirs were at or over their permanent overflow levels for the following periods :-
Reservoirs. Capacity to permanent overflow level, (Million gallons.) Period. Taitam, 384.80 51 days between 24th June and 14th October. Taitam Bywash, 22.36 36 days between 24th June and 14th August. 223 days between 1st January and 24th December. Taitam Intermediate, 195.90 71 days between 17th July and 20th October.
