The discovery and removal of these sanitary defects
represent an enormous amount of labour by the sanitary
inspectors, who have now their respective districts well in
hand. It is found that continuous house to house inspection
is an absolute necessity if a good sanitary state of
the sub-district is to be maintained, as inspection will in
very numerous cases reveal serious defects which did not
exist on the occasion of a previous visit a few months
earlier.
I have to express my satisfaction at the manner in
which Assistant Inspectors Freeman and Poole have performed
their duties during the past year.
The method of ventilating sewers by upcast shafts
reaching above the highest points of the houses to which
they are affixed but terminating at a lower level than the
chimney tops, has been extended considerably during the
past year in the parish generally. When complaint is
made of offensive surface street ventilation, the removal
of the grating and the adoption of the above plan has in
every case removed the noxious emanations complained
of. In the case of the Bridge Road Sewer constant complaints
of the offensive odours emitted from the gullies
and ventilators, which forced their way through the
traps of the house drains, had for many years prevailed.
The adoption of upcast shafts by the Metropolitan Board
of Works has remedied this and not a single complaint
has since been received.
It is desirable that the svstem should be extended to
•/
all cases in which efficient ventilation of the sewers
does .not now exist, more especially in the case of the low
level main sewer running from East to West through the
whole length of the parish, the condition of which has
elicited numerous complaints.
