which all interested therein confidently hope will accomplish
satisfactorily the great end for which it has been
designed. A short account of that portion of the scheme
which refers to the Southern Metropolis, will I trust not
be considered an unprofitable occupation of the time of the
Vestry.
Southern
High Level
Main Sewer
The design of the Southern Main Drainage consists of
two systems of Arterial Sewers, viz. High and Low Levels,
The former being intended to intercept at the foot of the
high ground all the drainage above it, and to convey the
same by gravitation to its ultimate outlet at Crossness Point
in the Erith Marshes.
Effra Relief
Main Sewer
In connexion with this work there is also the Effra Relief
Line, intended to intercept the more elevated, and equally
impure drainage arising in the locality of Norwood, which is
at present the principal feeder of the Dulwich open Sewers,
some of which open Sewers affect in their course the salubrity
of one of the most rural and valuable portions of this
parish.
Low Level
Main tsewer
The Low Level Sewer is designed with the view of affording
to the lower portions of the Southern Metropolis a
permanent outfall, by means of pumping, and thereby
ridding it of the constantly recurring results produced by a
pent up and tide locked system of sewerage.
Having glanced at the foregoing propositions, I will now
describe somewhat more fully (as far this parish is concerned)
the intended course of these main lines, as well as
the results to our own local sewerage, which they are calculated
to produce.
