The work of removing from the sewers deposits which accumulate there is one
of considerable magnitude. For this purpose the county is divided into four districts,
each district being made the subject of a separate contract. Contracts are
based upon prices for the cartage and disposal of the deposit which is removed from
the sewers bv the Council's staff. The cost of this work in 1927 was approximately
£3,400.
Flood relief
works.
The Council on 22nd July, 1919, had before it a comprehensive scheme of works
to mitigate floodings in various parts of London on both sides of the river Thames
during times of heavy rainfall. The scheme, which is described in the Annual
Report for 1920 (Vol. III., p. 121), specified seventeen works and the total estimated
cost, based on pre-war conditions, was £2,467,150.
The first work undertaken was the construction of the north-eastern storm
relief sewer from Kelvin-road, Highbury, to the Thames at Shadwell, which was
commenced in 1921.
In order to provide additional employment the Council on various dates subsequently
decided to accelerate the work on other portions of the 1919 scheme,
particularly those which would provide work suitable for unskilled or partly skilled
labour. The works selected were the improvement of the river Graveney, the
Wandle Valley sewer, the Charlton storm relief sewer, flood relief works at Hammersmith,
the enlargement of the Isle of Dogs and Abbey Mills pumping stations, the
south-western storm relief sewer, storm relief sewers in Lewisham and Woolwich
and the north-western storm relief sewer. All these works have been approved
for grant by the Unemployment Grants Committee.
A further item in the scheme, the construction of the Beverley Brook relief
culvert, which was commenced in 1925, did not rank for Government grant.
Of the 17 specified works included in the scheme of 1919, 12 have been
completed or are in hand. The estimated final cost shows an increase of about 72
per cent, on pre-war figures.
The completed works comprise the improvement of the river Graveney completed
in January, 1923 (cost, approximately £200,000), the Wandle Valley sewer
(first portion) completed in January, 1924 (£175,000), Charlton storm relief sewer
completed in March, 1924 (£150,000) the north-eastern storm relief sewer completed
in September, 1924 (£700,000), the Beverley Brook relief culvert completed
in September, 1926 (£38,450) and the Lewisham Branch sewer completed in
October, 1926 (£246,656).
Further particulars of these works are given in previous Annual Reports.
Details of the schemes which were completed during the year under review, or
were still in hand at the end thereof, are given below.
The enlargement of Abbey Mills pumping station involves alterations in the
Worthington engine house (now known as the Gwynne engine house), at the station,
the installation of new pumping plant there, and the provision of additional boilers
in one of the boiler houses and of supplementary plant. This work was completed
at an approximate cost of £60,000.
