Discharge of Trade Effluents into Sewers.— Under the provisions
of the London County Council (General Powers) Act, 1953,
the Borough Engineer's Department consulted with various public
bodies and carried out a site survey from which a list of 351
premises was compiled where trade effluents are discharged to the
public sewer. A further survey of premises has increased the number
of premises likely to discharge trade effluents to a total of 356. Of
these, 65 connections are directly to sewers under the control of the
London County Council and will be dealt with by that authority,
under the provisions of the Act.
In connection with this matter the Borough Engineer has
kindly supplied the following information:—
Premises discharging trade effluent to local sewers 291
Premises discharging trade effluent to L.C.C. sewers 65
Number of sewer connections inspected 26
Number of samples taken 19
Number of samples found satisfactory 15
Applications for new or modified discharges nil
The unsatisfactory samples were found to be caused by errors
in operating manufacturing plant and lack of maintenance of
drainage systems. Remedial measures were taken by the firms
concerned.
It is understood that negotiations are still proceeding between
the L.C.C. and the South Eastern Gas Board concerning discharges
to the Tunnel Avenue sewers.
Water Supply.—The whole of the Borough is supplied with
water by the Metropolitan Water Board which is a Statutory undertaking,
and the responsibility for its purity rests with that Authority.
There are 24,507 dwellings with direct connections to the Board's
mains.
During the year 166 water supply certificates were granted
under Section 95 of the Public Health (London) Act, 1936. Water
fittings have been amended in 249 cases.
Underground Water Supplies (Wells).—In August, 1947,
at the request of the Ministry of Health, a survey of underground
water supplies was made and full particulars were given in the
Report for that year.
In all, 40 wells are listed, only 2 of which are used for the
supply of water for drinking purposes. Of the remaining 38 wells,
13 are used for commercial purposes and 25 disused.
During September of 1953 a further shallow well was sunk
on the premises of the Tunnel Glucose Refineries Ltd., at Tunnel
Avenue, thus making 3 wells in all on this property and bringing
the total of wells in the Borough to 41. This new well is to be used
for industrial purposes only.
