of sewers with a view of some uniform system being
adopted for dealing with complaints of offensive emanations
from gratings connected with both local and main sewers."
Two of the resolutions adopted by the conference were
to the following effect :—
"1. That the closing of sewer ventilators, in response to complaints, increases
the general evil, the diminution of which is to be obtained by the
multiplication of the ventilators at regular frequent intervals.
"3. That pipe ventilators up buildings, or otherwise, where possible, should
always be adopted in addition to surface ventilators."
The engineer reported subsequently that—
"The general result of the conference confirmed the action of the main
drainage committee and the Council in recent years, and that the remedy
for sewer emanations is to be looked for from the maintenance of more
ventilating openings, both at the street level and by means of pipes
carried up houses and other buildings."
Upon the recommendation of the engineer, the main
drainage committee directed the report to be printed, and
copies thereof to be sent to each member of the Council, and
to the engineers and surveyors of the district boards and
vestries in the metropolis. The decision of the Council to
ventilate the main sewers by large and lofty iron pipes at
intersections of roads, street refuges, &c., referred to above,
may, perhaps, be regarded as an outcome of the deliberations
of the conference.
