The upper layers of the clay as seen in road cuttings and
openings made for the foundations of houses present considerable
variety in composition and colour. Brown beds
intermingle with others containing yellow sands Dark
smoke-coloured clay streaked with greensand, pyrites and
pebbles lies underneath the superficial brown beds and
occasionally outcrops through them. This prevalence of
clay renders the district damp, a fact of some importance in
connection with housing.
WATER.
The district is supplied with softened water by the Colne
Valley Water Company from their works at Bushey.
An analysis made in July 1920 showed that the water was
satisfactory for drinking and for domestic purposes.
The supply is constant and was quite sufficient throughout
the year.
DRAINAGE AND SEWERAGE.
The sewage of the greater portion (about two-thirds) of
the Urban District is purified by chemical precipitation followed
by land filtration at the Newton Sewage Farm on the Western
border of Roxeth. The effluent was quite satisfactory throughout
the year.
The sewage of the remainder of the District (about onethird)
adjoining Wealdstone, is disposed of by the Wealdstone
District Council to the satisfaction of all concerned. The
effluents of these farms run into the Kenton and Yeading
Brooks, tributaries of the Brent.
CLOSET ACCOMMODATION.
All the houses in the district are supplied with water
closets. There are a dozen water closets without flushing
cisterns.
There are no earth closets or privies in the district.
SCAVENGING.
House refuse is stored in covered and movable ashbins.
There are a few fixed receptacles It is removed by the Council
once a week. During the year 20 complaints of non-removal
were received. During the year 34 house-holders were called
upon to provide new ashbins.
I here are 3 houses in remote parts of the district whose
drains empty into cesspools. The cesspools are emptied by
the occupier. No nuisance has been detected in connection
with any of these during the year.
