WATER SUPPLIES.
Examinations were made each month of the water, both filtered and unfiltered, from the following supplies :-
Pokfulum.
Elliot.
West Point.
Albany. Bowen Road.
Eastern.
Shaukiwan.
Chai Wan.
Kowloon.
From October onward, monthly examinations of the water from Shing Mun were also made.
Weekly examinations have been made of the unfiltered and filtered water supply of the Dairy Farm Co. at Pokfulum, and free chlorine tests made on the Company's storage tank.
From 20 to 30 samples of tap water from all parts of the city have also been taken weekly for examination. The total number of water samples examined during the year was 2,269 as against 1,774 in 1928.
The water shortage during the year was the cause of a great deal of extra work being thrown on the staff. Many new wells were opened and spring supplies tapped, involving a large number of analyses. Samples of all supplies available to the public were brought in by the Sanitary Department, and in addition an order was made that any private individual could bring a water sample to the Laboratory and have it analysed free of charge.
Samples from many outside sources were examined, from the Canton River; from Foochow, from Manila, from Japan, etc. about 20 in all. 42 samples taken from the tanks on the Canton boats were tested also.
One of the staff proceeded by boat to Canton, taking samples at various points in the river, both up and down, to ascertain to what extent this could be utilised. The Acting Analyst together with the Government Bacteriologist made an examination of the water of the Lo Wu River near Sheung Shui, unfortunately finding this too saline for practical purposes.
