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, at a cost of approximately
£60,000. At the end of the year the enlargement of the station was
practically completed.

station.
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 was well advanced
at the end of the vear.

The scheme of relief sewers in Lewisham and Woolwich is described in the
Annual Report for 1923 (Vol. III., p. 128). One of the sewers in question, namely,
the Eltham sewer (from the junction of the Council's existing Eltham sewer and the
local sewer in Eltham-road, near Eltham-green, to the southern high-level sewer
No. 2 at Chalton), was completed during the vear at a cost of £207,562.

The scheme also provided for two branches of the Lewisham branch sewer to
Hither-green and Lee-green respectively. Serious complaints had been made in
recent years of flooding in the neighbourhood of Hither-green, and the development
of the Council's Downham housing estate will, to some extent, increase the present
demand on existing sewers at Hither-green. A desirable improvement in the local
sewers in the district also depends upon the construction of the branch sewer to
Hither-green, and the Council therefore decided to undertake the construction of
the sewer 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 Mav, 1927.
Northwestern
storm relief
sewer.
The north-western storm relief sewer extends from Kilburn to Hammersmith
and has been designed to relieve floodings in Willesden, Paddington and
North Kensington. The works comprise the construction of the principal sewer
which is connected with the Ranelagh sewer in Shirland-road, Kilburn, and
runs to the nearest point on the Thames, at Hammersmith, connecting with
various main sewers on the way. Branch sewers connect the new sewei
with the middle level sewer in Ladbroke-grove, and with the Wood lane sewei
at Wormwood Scrubs. A connection has also been made with the new
pumping station at Hammersmith. Altogether the construction of about 5£ miles
of sewer is involved, the approximate cost being £527,000. The principal sewei
has been constructed for a length of about 2£ miles in tunnel, largely under
compressed air, of cast-iron segments lined with concrete, including the connection
from the Hammersmith Pumping Station to the Stamford Brook Sewer in King
Street, Hammersmith. The remainder of the total length of about 5¼ miles,
including the branch sewers named, has been constructed in brickwork in tunnel,
except for two short lengths in cast-iron segments lined with concrete. The work
was let in two contracts, one for the cast-iron sewers, and the other for the brick
sewers. The works are complete and the sewer was in full use in September,
1927.
Southwestern
storm relief
sewer.
The south-western storm relief sewer has been designed to assist the drainage
of Clapham, Streatham, Brixton, West Norwood and Dulwich. It has been completed
at an approximate cost of £300,000. If required, the sewer can be extended
southward to relieve the Effra Branch sewer at West Norwood. The sewer from
Effra-road to Nine Elms was completed in March, 1926. The question of extending
the sewer southwards was considered, but storm relief works were more urgently
reauired elsewhere, and were given preference. To give relief to an area where
