this latter Work would provide the means of eventually diverting
a large portion of the Sewage (which for the present must
have a sluggish outlet into the existing Park Road Sewer) by
the construction of intercepting lines along the Commercial and
adjacent Roads, and which in effect would cut up the proposed
new line of Sewer in the Park Road into short lengths, and
thus produce for it additional and nearer outlets towards the
"Main Line," and which would ultimately relieve it from any
inefficiency of working through the present want of fall.
Another reason may be assigned in support of the efficiency
of this line of Sewer (even under its present disadvantages)
viz., the construction of the "Pumping Establishment" before
spoken of, producing as it will a continual drawing off of the
Sewage towards the outlet, and thus partially compensate by
a constant flow for the deficiency of fall at present attainable
in the proposed route.
Nevertheless, I would here remark in justification of my
former Reports on this matter, as well as the general plan for
the entire Sewerage of the Parish prepared by me in 1856,
that it would have been far preferable had the improved
"Main Sewerage Works" therein anticipated, been constructed
so that no expedient should have had to be resorted
to, such as has led to the necessity of this explanation.
I hope I have succeeded in making this subject better
understood, and for this purpose have also appended to this
Report a plan to illustrate the present and probable future
working of the proposed Sewers.
During the past year to which this Report has reference,
