question relating to building materials. The work of pipe founding was entrusted to the Stanton Ironworks
Company, Limited, Notts., and to the Staveley Coal and Iron Company, Limited, Chesterfield, in
approximately equal proportions. For laying and fixing the pipes the tender of Mr. Whittaker Ellis,
amounting to £15,169, was accepted. All the tenders referred to are subject to adjustment in respect
of any variations in the cost of labour and materials.
The Northern outfall sewers are above the ground level from Old Ford to the outfall at Barking,
and they run in an embankment. During 1920, repairs were authorised to the road on the embankment
between the outfall and High Street South, West Ham, at a cost not exceeding £1,000. Barbed
wire fencing has been erected in place of broken fencing along the foot of the embankment at a cost of
about £1,000. £3,000 has been authorised for repairs to the bridges supporting the Northern outfall
sewer.
Outfall and

sewer.
To mitigate floodings on low ground in Greenwich and Woolwich, alterations were authorised
to the Southern outfall sewers and a local sewer in Greenwich-road at an estimated cost of £1,450.
The Southern high-level sewer No. 1(Clapham to Putney extension) is carried over the Wandle
by means of the Wandsworth aqueduct, which consists of a series of brick piers and arches. For many
years a lateral movement has been taking place, the greatest deviation from the perpendicular being
23½ inches. It is essential that support should be given to the structure and brick buttresses are being
placed against certain of the piers, the estimated cost of the work being £2,000.
To alleviate flooding near Queen's-road, Battersea, a local sewer in Lavender-hill has been connected
with the southern low level sewer No. 2 at a cost of approximately £718.
Repairs to old main sewers have been authorised during the year as follows—(i.) £4,000 for Eelbrook
sewer, (ii.) £3,000 for Fleet sewer, (iii.) £2,000 for Hackney-brook sewer, (iv.) £3,000 for Londonbridge
sewer, (v.) £5,000 for Ratcliff-highway sewer, (vi.) £2,000 for Ranelagh sewer, (vii.) £2,000 for
Regent-street sewer.
Main sewers.
The upper end of the Counter's Creek sewer ceased to be used as a main sewer, and, as it interfered
with the development of the St. Quintin housing-estate belonging to the Kensington Royal Borough
Council, its retention as a main sewer was formally terminated and the Borough Council accepted future
liability therefor.
The Council on 22nd July, 1919, had before it a scheme as follows of works to mitigate floodings
in various parts of London during times of heavy rainfall:—
Flood relief
works.
North Side.
Pumping-station at Hammersmith and new relief sewer from Hammersmith-road (Hammersmith
storm-relief sewer)
Enlargement of Lots-road pumping-station and new relief sewer from Walham-green. (Walham-green
relief sewer)
Storm-relief sewer from Kilburn and Shepherd's Bush to Hammersmith (North-western stormrelief
sewer).
Alterations to King's Scholars' Pond sewer and pumping-station.
North-eastern storm-relief sewer.
Storm-relief to Fleet sewer.
Alterations and new engines at Abbey Mills pumping-station.
Isle of Dogs pumping-station enlargement.
Supplementary works.
South Side.
Beverley Brook relief culvert
Wandle-valley sewer—1st portion.
Wandle-valley sewer—2nd portion.
Improvement of the River Graveney.
Storm-relief sewer from Norwood, Streatham and Dulwich to Vauxhall (South-western stormrelief
sewer).
Shad Thames pumping-station—Additional engines.
Storm-relief sewer and storm water pumping-station at Deptford.
Storm-relief sewer from high-level sewer No. 2 to River Thames at Charlton (Charlton stormrelief
sewer).
Storm-relief sewers in Lewisham and Woolwich.
Supplementary works.
The construction of the north-eastern storm-relief sewer had been decided upon before the war,
and the plans were practically complete, but the Government restrictions on expenditure during the
war prevented the work from being undertaken. The proposed sewer will run from Kelvin-road, Highbury
to the Thames at Shad well, a distance of about 4 miles. The initial diameter will be 8 feet;
this will be increased at points of connection with other sewers and its ultimate diameter will be 11 feet
4 inches. From Highbury to Bethnal Green-road the sewer will be of brick, and from the latter point
to the river in cast-iron tunnel. By relieving the pressure on existing sewers, the new sewer should
mitigate floodings over a widely spread area including parts of Islington, Stoke Newington, Hackney
and Shoreditch. The differences in construction lend themselves to a division of the work, and the
sewer has been made the subject of two contracts. For the section from Highbury to Bethnal
Green-road, seven tenders ranging from £342,928 to £610,548 were received, and for the remaining
61001 R
