Annual Report of the London County Council, 1911.
All works specifically referred to above have been completed with the exception of the sewer
from Holloway-road to the Thames. Further borings and other preliminary work in connection with
the proposal that the outlet of this sewer should be at Shadwell instead of the Tower were carried out
during the year.
Certain other works, not specifically mentioned above, were provided for in the estimate of the
cost of the flood prevention scheme. One of the most important of these was the enlargement of the
storm water pumping station on the Isle of Dogs. The existing plant consists of two steam-driven
reciprocating pumps, and it is proposed that the station shall be extended so as to accommodate two
centrifugal pumps driven by gas. The cost is roughly estimated to amount to £30,000.
The two schemes referred to above included the undermentioned works which had for their
object specifically or incidentally the relief of sewers in the Metropolitan Borough of Wandsworth—
(i.) the Wandsworth and Battersea relief sewer; (ii.) the Falcon-brook pumping station, and (iii.)the
southern low-level sewer No. 2. Owing, however, to the very large development of building operations
in the borough since the schemes were prepared, it is considered essential that other large works must
be undertaken, and the Council on 7th November, 1911, agreed to the following proposals :—
Estimated cost.
1. To construct a relief sewer from the junction of Balham
road and Tooting Bec-road to the river Graveney £28,000
2. To improve certain portions of the waterway of the river Graveney 5,750
£33,750
Cost of new
works.
It is also proposed to carry out extensive works for the relief of the area in the valleys of the
rivers Wandle and Graveney. The details of these works have not yet been settled, but the expenditure
involved will probably be considerable.
The payments on capital account up to 31st March, 1912, in connection with main drainage
extension and flood relief works amounted to £3,703,358 15s. 8d.
Drainage of
out-county
districts
In addition to the County of London, several neighbouring districts make use of the London
main drainage system; the necessary powers to enable the Council to receive and deal with the
drainage of these out-county areas having been conferred by Parliament from time to time. In every
case in which the sewage is received and dealt with, each out-county authority is required to make
to the Council an annual payment, the amount of which varies in the several districts. The districts
concerned, and the statutes dealing with the disposal of their drainage, are as follows:—
[(i.) Hornsey, under the Hornsey Local Board Act, 1871, the Metropolitan Streets Improvement
Act, 1872, and the London County Council (General Powers) Act, 1906.
(ii.) Tottenham under the Tottenham and Wood Green Sewerage Act, 1891, and the
. (iii.) Wood Green London County Council (General Powers) Act, 1908.
(iv.) West Ham, under the West Ham Corporation Act, 1893.
(v.) East Ham (part of), under the London County Council (General Powers) Act, 1897.
(vi.) Willesden, under the Willesden Sewerage Act, 1896, and the London County Council
(General Powers) Act, 1908.
(vii.) Acton, under the London County Council (Acton Sewage) Act 1898, and the Acton
Sewage Act, 1905.
(viii.) Penge, under the Penge Scheme, 1900.
(ix.) Beckenham (part of), under the Beckenham Sewerage Act, 1873, and
(x.) Upper Norwood, under the London County Council (General Powers) Act, 1903.
Small parts of Ealing, Chiswick, and Mitcham also drain into the London system.
A joint application from the Urban District Councils of Edmonton, Enfield, Leyton, Southgate
and Walthamstow, that the sewage of those districts may be received into the London main drainage
system, has been under consideration for some time, but there are so many important details requiring
to be settled, that it has not been possible up to the present to arrive at an agreement in the matter.
Under the provisions of the Willesden Sewerage Act, 1896, the sewage and drainage of the
portion of the district of Willesden draining naturally towards London are received into the London
main drainage system, and in the London County Council (General Powers) Act, 1908, authority was
obtained for dealing in the same manner with the sewage and drainage of the remaining portion of
the Willesden district which drains towards the river Brent. The Act, in addition to restricting the
quantity of sewage and rainfall which might be discharged into the London sewers, provided—
(1) That the Willesden Council should construct all sewers and works necessary to convey
the sewage and drainage to the county boundary.
(2) That the Council should construct, at the expense of the Willesden Council, a sewer
from the county boundary to the middle-level sewer No. 2.
(3) That the Willesden Council should pay (a) a differential rate of lid. in the £,
calculated on the rateable value of the Brent area, in addition to the proportion of the county
rate levied by the Council each year which is applied for main drainage purposes; and (b) a
capital sum of £40,000 in respect of discharged capital outlay on main drainage works,
