Of the 17 specified works included in the scheme of 1919, 10 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), the Lewisham Branch sewer completed in October,
1926 (£246,656), enlargement of Abbey-mills pumping station completed in 1926
(£37,700), north western storm relief sewer completed in September, 1927
(£465,000).
The formal opening of Hammersmith storm water pumping station was performed
by the Chairman of the Council (Sir John Gatti, J.P.), on 20th January,
1928. The station deals with storm water from Hammersmith and parts
of Fulham and Kensington. Two new low-level sewers bring the storm water
to the pumping station. The equipment of the station consists of five 4-cylinder
gas engines, each 480 B.H.P. coupled directly to five centrifugal pumps, each having
a discharging capacity of 200 tons of storm water a minute. The approximate
cost of the station and the new sewers was £250,000.

On. 28th October, 1928, a rainstorm occurred, which put the capacity of the
station to a severe test. The storm lasted for nearly 4½ hours and was heavy and
widespread. At the height of the storm the five pumps were put into operation
simultaneously for the first time and worked together for 1 hour. During the storm
a total quantity of 32½ million gallons of water was pumped from the station into
the river Thames.
In addition to the pumping carried out at Abbey Mills pumping station in
connection with the drainage of the low-lying areas in Poplar and the Isle of Dogs,
storm water from these areas is pumped direct into the Thames at the Isle of Dogs
pumping station, and the general flood relief scheme of 1919 provided for the enlargement
of this station and the substitution of gas for steam power. During the year
the enlargement of the station was completed at a cost of approximately
£51.750,

Shad Thames pumping station, opened in 1909, was designed to accommodate
six pumping sets, but as a first instalment three only were put in. The flood relief
scheme of 1919 included proposals for completing the equipment of this station.
The second instalment, consisting of three engines and pumps, is being added at
an approximate cost of £22,000. The installation of the machinery is almost
complete.

The scheme of relief sewers in Lewisham and Woolwich is described in the
Annual Report for 1923 (Vol. III., p. 128). The scheme provided for branches of
the Lewisham branch sewer to Hither-green and Lee-green respectively. The
Council decided to undertake the construction of the sewer to Hither-green at an
estimated cost of £57,000. The tender, amounting to £53,004 13s. 5d., submitted
by Messrs. Kinnear, Moodie and Company, Victoria-street, S.W.I, for the construction
of the sewer was accepted on 26th May, 1927, and the sewer was put into use in
August, 1928.

The Streatham and Balham storm relief sewer was constructed in 1912. It
receives the overflow of the main and local sewers at Tooting Bec-road, and discharges
into the River Graveney at Collier's-wood. A further extension which would tap
the main sewer further along its course and increase its usefulness was provided for.
The Council decided to proceed with the construction of an extension of the sewer
to Ritherdon-road, a length of about 400 yards, at an estimated cost of £12,000.
