SANITARY CIRCUMSTANCES OF THE BOROUGH.
Water.—The North and South Greenford and Northolt
Wards are supplied by the Rickmansworth and Uxbridge Valley
Water Company with the exception of five roads in Greenford
North Ward which are supplied by the Colne Valley Water Company.
The rest of the Borough is supplied by the Metropolitan Water
Board.
There are eight factories in the Borough using water from
deep borings ranging in depth from 300 feet to 600 feet. The
water is used for general factory purposes and in four of them
it is also used for drinking. Samples from these four supplies
were taken and submitted to chemical and bacteriological analysis
and the report in each case was that the water was satisfactory
for drinking purposes.
Samples were also taken from a shallow boring of water
which was used in a dairy in connection with the milk cooler
and the cold store compressor. The analysis in this instance
showed the water to be polluted and its use in the dairy was
prohibited.
Rivers and Streams.—No complaints were received during
the year with reference to the river Brent or its tributary stream.
Drainage and Sewerage.—With the exception of 52 houses
in Northolt Ward, ten in Greenford North Ward, one in Hanwell
North Ward, two in Mount Park Ward and five in Drayton Ward,
all houses in the Borough are supplied with water closets and are
connected to the sewerage system. During the year one house
previously drained to a cesspool was connected to the sewer.
Closet Accommodation.—Excepting those parts of the Borough
already mentioned the whole of the houses are provided with water
closets, there being as a rule one water closet for each house or
part of a house let as a separate tenement.
The following table gives the number of pail closets, the number
of cesspools and the number of water closets connected therewith
in the areas mentioned:—
