Reference Number:

To Dr. Windle,
Southall-Norwood Urban District Council.
I beg to submit the following Report on the specimen of water for
bacteriological examination, marked 13W., received at the Laboratory on
7/7/02 :
This sample of water contains 160 organisms per c.c. The bacillus coli
communis was not found in 55 c-c- I entertain the same opinion of the water as
of No. I2W.
G. L. EASTES.
The Company is erecting a large Water Tower in the District, in
order to furnish a more constant supply at a greater pressure.
Disposal of Refuse.
(a) Household Dust.
All houses in the District are supplied by the Council with
galvanized iron dust-bins provided with covers. The collection is a
weekly one, carried on by a contractor who finds a shoot. The
amount of refuse removed from each house averages rather over one
load per annum. It will be a constantly increasing difficulty in future,
from the rapid extension of huilding operations, to dispose of this
material without causing nuisance, and I again urge you to consider
the advisability of providing a refuse destructor lor dealing with this
and other refuse.
(1b). Sewage Disposal.
I am indebted to our Engineer Mr. Reginald Brown, A.M.I.C.E.,
M.S.I., &c., for the following particulars as to the Disposal Works and
Farm.
The Sewage enters the Disposal Works at two different points.
What may be termed the high level outfall Sewer takes the Sewage
from the District proper. This enters the works by passing through
a small chamber controlled by valves and thence into and through a
receptacle in which is fixed one of Smith's Patent Revolving Wire
Screens.
This screen consists of a water wheel—driven by the momentum
of the Sewage—which caus'es an endless band of wire net to revolve
slowly, thus catching and lifting out all suspended matters beyond a
certain size. A brush revolving in an opposite direction cleans the net
as it passes and the solid matters are cleared to one side and removed
by manual labour. The sewage then passes through a well, inside the
liming house, and from thence through two valves into one or the other
of two small detritus tanks covered with corrugated iron. These
