that territory on the north side Of
the river, which is too low to drain.
into the Main avenue sewer.
| District No. contains $50 acres
and comprises all the territory
south of Commerce and East of
Garden and Water streets.
The main trunk line for this dis
trict is along the OLD city tract line
with branches through Presa, La
Dor and Plum streets.
District No. 3 contains 1856
acres and comprises the western
and northern portions of the gem
eral system. It's outlet is through
McCracken avenue and Guenther
street, crossing the river at Aran-
sas street through Arkansas street
to South Flores street, up
South Flores street to Camp street,
through Camp street to South La
redo street, and through South and
North Laredo streets to FrederiCks-
burg Road. A branch trunk line
sewer continues through South and
| North Flores streets to Utica street,
where the branch sewer from San
Pedro avenue connects. A small
branch sewer crosses the river at
Johnson street, to take the drain
age from the territory lying east of
South Flores street. 1t is proposed
to cross the river at both of these
points by means of inverted syphon,
shown on plate F and HI. This
line extends up City street, cross
ing the U. S. Arsenal grounds to
Aubury street and Dryer avenue.
The crossing Of San Pedro creek
on Camp street can be made on
grade line above the creek, by
means of wrought iron or steel pipe
riveted together and supported
by masonry abutments, shown on
Plate F.
Laredo street has but little grade,
being nearly level, and in cOnse-
quence it is necessary to lay the
sewer with a light grade. In some
places the sewer is not very deep
and may need some additional fill
ing.
| Also on Cameron street the sewer
lies near the surface in some places,
but from the indications of lateral
profiles it seems quite probable
that you intend raising the grade
of this street.
District No. 4 contains PIG acres
and comprises the southwestern
portion of the system. It's outlet
is through Simpson street dis
charging temporarily into the
river, but can be eventually taken
across the river into the general
system.
Plate A and B represent the de-
tails of the manhole frame, cover,
sand pan and step.
Plate G shows the method of
house drainage, with enlarged
drawings of traps, ETC.; also the
method of connecting house drains
in deep cuttings.
Plate d shows plans and details
of Standard manholes, sewer sec
tions, and flush tanks, also
special manhole for the intersec-
ton Of Navarro and Commerce
streets.
Plate f SHOWS plan of special
| manhole for the intersection Of
Guenther and Mill streets, stand
ard manhole on brick sewer, and
6.inch slant for house connections.
Also the method Of cOncreting
around the sewers, where roots OF
trees would be liable to enter and
choke the sewer.
Plate + shows the proposed man.
ner in which the river may be
crossed with the sewers at jose
phine, Johnson, Camp, Luna and
North Flores streets.
Plates q and II show the river
crossings at Garden, Navarro, Lex
ingtOn avenue and Arkansas streets.
1t is intended that these syphon
pipes shall be equal in capacity to
the sewer with which they are con-
nected, but as it will be many
years before the sewer will be
taxed to it's full capacity, it is best
to use only one of the syphon pipes
| for the present, so as to cause an
increased velocity through the
pipe, thereby keeping it free from
deposits. 1t will be advisable to
stop up those not needed at pres
ent.
Plate / shows special manhole
for Garden and Simpson streets
where it is intended to connect the
two outfall sewers.
Plate shows the plan Of outfall
sewers with sections Of sewage
carriers and sub-carriers, with stop
gates for irrigating.
