Sewer Department.
GENTLEMEN: In compliance with
your notice OF engagement under date of
August ", have the honor to submit
herewith my report upon q proposed in
tercepting sewer In In Brandywine creek
valley.
Accompanying the report is FIRST gem

Although my instructions properly
limit me to q consideration OF The area
embraced within this one basin, IL Is evil
dent that a proper treatment OF the
problem involved inc udes an examina-
lion of such Of the remainder of tn, city
rs is necessary to rightly comprehend a
systematic collection Of tie sewerage of
the entiro city at some future day; or at
least that the work done on this one
section shall be capable of harmonious
union with sewers eventually to be con.
strucied elsewhere In the city. These
considerations have properly Influenced
me In my work.
The conditions as I have found them
may be outlined as follows: The Bran
DIVINE creek with an approximate
average dry weather fl W OF l75, 1000. 900
gallons per drain) flows along the foot OF
the north tlope In the district under con-
sideration Tor approximately 1900 feet;
the district under consideration includes
approximately 025 acres, and is at pres.
ent occupied by population Of 1000
an i several large factories. In the lower
part of the district near French street the
pumping station OF the city water works
is located and It draws water from q race
extending 400 feet along the south
bank oil the Brandywine to a dam about

1t receives water from the creek.
Below Van Buren, street the surface
drainage from q portion Of the district
| under consideration Ia carried over the
race In la'ge wooden fumes into the
creek. which lies on u lower level. The
surface drainage here mentioned includes
large quantities OF domestic wastes, which
fnd their way directly into the cutters
in the uncovered districts. Leakage
from these fumes fall into the race, and
| this direct pollution of the water supply
of the city is further augmented by filtra-
Lion OF filth through the soil, Iotably
near the cemetery, and the addition TO
The water of the creek above the dam
already mentioned of increasing quanti-
ties of domestic and manufacturing
wastes through Rattlesnske and Cfooked
run, and from the factories q short dis
tance above the city line along the Bran
dywine. The mouth OF the race Is favor
ably located to receive large percentage Q
Of this pollution which Is naturally kept
by the currents of the creek along ils
south bank.
After speaking OF the determination OF
the Water Commissioners to RET ain the
pumping station at Its present location,
he refers to the report of Professor
Seeds, In reference 10 the impurities in
the water, and that OF Mr.. Herring on the
sewerage OF the city. He then con-
tinues:
As has been stated one of the
prime objects OF the construction
of the proposed sewer 10 to reliove
the race aud the water supply from
pollution. This end must constantly be
kept In view. 1t follows that the sewer
must be caIable of carrying away all
matters at present or alter the grow th OF
tho district capable OF jeopardlzlng the
water supply. To accomplish this pur-
poGe two methods suggest themselves
First, alter the ewage has been brought
10 the south bank Of The Iace, carry II in
short imperyious conduits under the race
directly into the creek; lateral soil drair-
age could for Iart Of this plan he dis
charged In tho same way; or, second, con-
struct an intercrptipg sewer OF suitab Bile
size to receive the flow from all branch
lines and conduct 1t parallel to the race
TO point on the creek below the pump
ing station. The fret plan for the present
would undoubtedly be the cheaper, but
the pollution in the creek at these points
would not hong be permissible and the
interceptlng sewer would then become
essential. No such temporlzing cou'd I've
couutenanced and the intercepting sewer
become necessary.
He makes careful calculation CT the
sewage that will probably flow into the
Brandywine from houses and factories in
tho near future, and then follows with
an estimate Of the size of sewer re-
qulred to carry It of. lie proposes tive
plans, either of which in his opinion
would accomplish the purpose. Tho es-
innate for constructing the interceptiug
sewer along the south of tho race Ii
{47,355.
The estimate for interce pting sewer
north OF the race Is $4i $50.
The report will be considered by the
Street and Sewer Commission at the next
meeting on Tuesday evening.
