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 my Report for 1945.
The part of Ilford within the area of the Metropolitan Water Board is
supplied with water derived from the River Lea, which after passing through
storage reservoirs is filtered and chlorinated at Lea Bridge and Ferry Lane,
and pumped from those works. An additional amount of water is supplied
from Wanstead 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 2,576
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 1948 was 1,425 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 over 3,300 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.
The length of mains laid by the South Essex Waterworks Co. in Ilford
during 1948 was 24 yards of 4-inch, and 487 yards of 6-inch.
There are now no public wells in existence. There are a few private
wells for commercial purposes.
4 samples of piped water supply (2 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. Survey of Main Trunk Sewers.—The
Borough Engineer has*kindly supplied me with the following statement:—
(a) Foul Water—Main Drainage Scheme.—Reference was made in my
report last year to a comprehensive report then being prepared by the
Borough Engineer on proposals to reconstruct the main trunk sewers
in the Borough so as to enable them to deal with the increased flow
resulting from building development both past and to be anticipated.
This report has now been presented to the Council and has received
approval. Details are now being prepared of the first section of the
scheme and negotiations are about to commence with the Port of London
Authority regarding storm water overflows into the River Roding which
forms an important part of the scheme. On completion of these
negotiations, this portion of the scheme will then be submitted to the
Ministry of Health for approval for loan sanction, a stage which it is
hoped to reach within the current year.
(b) Surface Water—Main Drainage Scheme.—A comprehensive
scheme to improve the main watercourses and main sewers discharging
into the watercourses was referred to in my last report and that portion
of the scheme which dealt with the Hainault Area of the Borough is
now before the Ministry of Health for the purpose of obtaining loan
sanction.
