more advantages than continuation Of the
present mode OF disposing Of the organic
waste matters OF your city This question
must answer entirely in the affirmative.
/ Then follows a number of conclusive
reasons why he answers In the affirmative.
The amount of roof water TO enter the
sewers must he gauged by circumstances.
| IL should be entirely excluded. or only a
small portion taken up where the sewage
requires pumping, as, for instance, on the
South Side and In portion of the Ninth
ward. Near the highest ends Of the sewers,
where the current Is very slight and irregn.
lar and Is more likely to cause 9 deposit, It
Is well to admit all Of the roof water
i.Near the outlets into the rivers ITS
introductions is not so necessary. The
next point 10 be considered is the outfall
Or place of discharge. There can be no
| debut that the sewage OF Wilmington must
all be ultimasely delivered into the Della
| ware river. The question of utilizing 1t for
4 agricultural purposes 10 locality like
| yours Is settled By the fact that It would
| cost much more TO get the. manurial ele-
| menis out of the sewage than they are
worth. The best plan is TO get rid OF them
as cheaply as possible and therefore, To
waste them into the river. The system must
| then be designed with the main Outfall ON
| the Delaware river. II should be located
above the mouth of the Cbristiana
river, for If below It the incoming tide
would be likely to carry much of the sew
| age back again to the city, unless retained
| In reservoir during such times. But
while the greater part Of the sewage should
| be carried to the Delaware 1t Is not neces-
eary that all of il should be taken there.
The Chrietiana river Is sufficiently large
and has q current sufficiently strong TO per
init always of a certain portion being
delivered into 1t without detriment. Espe-
eially is this the case II the sewage Is
discharged only during outhowing tide, and
retained in storage basins during the
rest OF the time, For this reason and
because any other outfall owing to its dis
lance would be less expedient and more
costly, have located q special one for the
South Side on the Cbristiana river opposite
the mouth of the Brandywine. The guam
tity of sewage from this section of the city
would be relatively small and II stored In
reservoir when the tide runs in an objec-
tionsble effect will never be observed. The
point Of discharge is on the deep water side
of the river, and it is also exposed TO the
flushing effects of the Brandywine, which
occasionally swells to q very powerful
stream.
The alignment of the other sewers can
best be understood by glance at the plan.
I have endeavored to place them mainly on
such streets upon which the houses front,
and thus making them more serviceable
than on the streets at right angles to them.
1t was also my aim to use with preference
back streets In order to shorten the length
of private drains and obviate their passing
through the cellars to the front. Should
this method be preferred by owners more
generally the lines of the sewers can often
H., t,h al until init ns-fa
| ing with the other part OF the system. For
economical reasons have placed main
sewer along the Rattlesnake run, but
should there be difficulties in the way of
passing over private ground it can be laid
on Clayton street, yet without being of
equal benefit to Incorporates adjoining the
run. Should the brick sewer now built on
Fifth street not be low enough at its upper
1 end to receive the seWage from Fifth and
Poplar streets, as required by the plan, then
| the sewage from this point must be inter
| cepted on Lord street instead.
THE COST.
The public and private sewers recently
| built In the city can readily be embodied
into the proposed system if they are found
| to be In a sound condition.
The subject which yet remains to be dis
eussed is the question of cost. The system
as shown upon the plan has been extended
/ over nearly the entire area of the city al
| though harlly one-half of it is now built
| up. II is capable, with this extension, of re-
| lieving. population of 100000 persons.
| The following estimate of cost covers
/ the entire system required for this
1 population which Is double the present one.
II can OF course be only approximate, but 1t
is accurate enough TO permit fair idea to
be gained of the necessary expenses and OBJ

With about this sum the more densely
Inhabited parts Of WILMINGTON could be

Temporary outfal into the Christiana.
With $40 900 it would be possible at once
to reach the Delaware.
As IL is not well in private establishments
at first to build works extensive enough to
accommodate a business not expected for
many years, but as it is better to arrange
those that are at first needed in a way 10
permit OF easy aud economical future exten-
sion, so will the same plan be preferable in
municipal works; aad in designing the
above system have paid special attention
to this potnt, not only as regarding the out
fall but also In each district as far as prac
ticabe.
