forms the western boundary ; it has a river frontage of
about 4½ miles, and the northern portion of the distuct
which lies along the river is about 1,689 acres in extent,
and consists of marsh land, the level varying generally
between 3 and 7 feet above ordnance datum, and being

B.—Sanitary circumstances of the District.
(1) Water Supply.
This is obtained from the Metropolitan Water
Board. The water is very hard, but of good quality, and
the supply is ample
(2) Drainage and Sewerage.
The main portion of the sewage of the district is
carried by a sewer which was completed and opened in
1898. This sewer consists of two portions, one taking
sewage from the low-lying areas and running from the
western boundary near Abbey Wood Railway Station to
Erith, and the other draining the upper part of Belvedere
and Northumberland Heath. The first mentioned
portion is worked by the Shone Pneumatic System,
ejectors being situated about every half-mile throughout
its length, and worked by compressed air from the Outfall
Works at Anchor Bay. No ejectors are required
on the second portion, as there is a very good fall
throughout the whole length of the sewer.
The Sewage Outfall Works is situated at Anchor
Bay at the eastern end of the district, and after treatment
by septic tanks, aeration beds and percolating
filters, the effluent is discharged into the River Thames.
There are 6 percolating filters with revolving distributors.
The plant at the Outfall Works consists of:—
1 50 h.p. gas engine working air compressor.
