SECTION C.
SANITARY CIRCUMSTANCES OF THE AREA.
(i) Water Supply.—The district is served by the Metropolitan Water
Board and the South Essex Waterworks Co., both maintaining a constant
supply. The subject of the water supply of the Borough was dealt with at
length in the Report for 1945. .
The part of Ilford within the area of the Metropolitan Water Board is
supplied with water derived from the River Lee, which after passing through
storage reservoirs is filtered and chlorinated at Lee Bridge and Ferry Lane,
and pumped from those works. Contact tanks are now in operation at
these works in which the dose of chlorine is able to exert its full effect
before the water passes into the distribution system. An additional amount
of water is supplied to the area from Wanstead well and Rammey Marsh
well.
Samples of the water in all stages of purification are analysed daily at
the laboratories of the Board.
Lieutenant.Colonel E. F. W. Mackenzie, Director of Water Examination
of the Board has kindly supplied me with the information that 1,998
samples of filtered water were submitted to chemical and bacteriological
examination and found to be pure and wholesome. All new and repaired
mains are chlorinated before being restored to use and samples of water
from them are tested bacteriologically. The water is not plumbo.solvent.
The length of mains laid by the Metropolitan Water Board in Ilford
during 1950 was two yards of 3.inch and 743 yards of 4.inch.
The water to the other part of the area is supplied by the South Essex
Waterworks Co. The supply is obtained from the River Stour and from
deep wells at Mill Road, Grove Road and Roding Lane.
Mr. Hugh G. Ramsay, Engineer to the South Essex Waterworks Co.,
has kindly supplied me with the information that just under 4,000 chemical,
bacteriological and biological examinations were made at the Langham
laboratory, and all were reported as wholesome. The samples taken were
from wells and houses in various parts of the area. A supplemental supply
of water was obtained from the Metropolitan Water Board for the period
18th February to 3rd June.
The length of mains laid by the South Essex Waterworks Co. in
Ilford during 1950 was 46 yards of 3.inch, 247 yards of 4.inch, and 7 yards
of 6.inch.
There are now no public wells in existence. There are a few private
wells for domestic and commercial purposes.
5 samples of piped water supply (3 South Essex Waterworks Co. and
2 Metropolitan Water Board) were taken for chemical and bacteriological
examination, and all gave satisfactory analyses.
(ii) Drainage and Sewerage.—The Borough Engineer has kindly
supplied me with the following statement: —
Ilford Corporation (Drainage) Bill. This bill has been passed by
both Houses of Parliament and has received the Royal Assent. It is
now known as the Ilford Corporation (Drainage) Act, 1950. It is
hoped to commence the work which the act authorises during 1951.
Flooding of Streams. No serious flooding of streams occurred
during the year.
Pollution of Streams. There was no serious instance of pollution
of watercourses during the year.
