DETAILS OF CONSTRUCTION.
The specifications provide for Y
for transformations, to be
built in the sewers during construc-
ton and opposite every lot or build
ing; these will be temporarily closed
until the house-connections are made.
It will, therefore, not be necessary to
break into sewer whenever connec-
ton is required, but if an accurate To-
cation of these Y branches is kept on
record, as should be done, the sewer
may be opened up at any desired
branch and connection made with
out injury to the sewer.
Catch basins, three or four in num-
Der, for the collection of the surface
water from the street cutters, will be
built generally at all street intersec-
tions reached by the system of storm
sewers. These catch-basins are ar
ranged so that the heavy matter from
the streets will collect in them instead
of passing into the sewer, and this
must be removed as occasion requires,
generally after every heavy rain.
All brick sewers will be circular in
Manholes for both sys
TENS of sewers will be located gener-
ally at all street intersections, and
midway in the longer
blocks. Lampholes will be built in
the small or sanitary sewers, general
ly midway of manholes where exceed
ing 800 feet apart. These manholes
and lampholes permit of access to the
sewers for inspection and cleaning
whenever necessary. All changes in
grade or alignment of sewers will oc-
cur at manholes, so that the sewers
will be straight and can be seen
through by any two manholes.
Manholes and lampholes have per-
forated covers for the ventilation of
the sewers; in order to prevent the
dirt from falling into the sanitary sew
ers through the ventilation open
ings, iron pans will be hung under
each manhole cover. These pans must
be emptled as occasion demands.
Flush-tanks will be used at the
head of all long branches in the SAM
tary sewers. These fush-tanks are
arranged for the automatic and quick
discharge of 800 gallons or more of
water, depending upon the size of the
tank, once for "a hours, more or less
frequently, as may be desired. A large
sized tank has been arranged for the
simultaneous flushing of twin sewers
when these occur. Those branches
for which fush-tanks have not been
provided can be flushed as often as
may be necessary by a fire stream
from hose attached to the nearest
fire hydrant.
USE OF SEWERS.
Previous to the construction of the
sewerage system, it will be wise to
pass suitable ordinance setting forth
the regulations governing the use Of,
and connection with the public sewers,
and providing that the work be done
only by regularly licensed plumbers.
Only by some regulation of this kind
can the use of improper fixtures, ap-
purtenances, and faulty construction
of plumbing and transformations
about private premises be prevented,
and unless these connections, with all
their appurtenances are properly ar
ranged, the sewers will probably soon
become INSTRUCTED and involve upon
the city constant expense for clean
ing them. It must be remembered
that sewerage system is not intend
ed for the removal of garbage and SOL
id kitchen refuse, but only for water
closet and other liquid wastes; house
connections should be so made that
any abuse in this matter will result in
annoyance and expense to the guilty
party, by stoppage on his own
premises rather than in the public
sewers. All connections with the pub
lie sewers are made, generally,by and
at the expense of the property owners.
ESTIMATES.
l have made estimates for the cost
of such portions of the work as seems
likely to first demand your considera-
ton. The Washington street main
sewer beginning at Fourth street and
extending to the river, exclusive of
any cost for right of way from Bridge
street to the river, will he as follows:
1885 nneai feet of 10 inch pipe
sewer at $1O5 $1.7l6 IS
manhOles at $46 216 90
3 lamphOles at S12 36 90
"a house connection chimneys at 81 Is 90
Total cost S2,O96 Is
If the branch on Second street from
Washington to Elm streets be built,
the cost will be as follows:
375 feet of inch sewer at S118 $442 SC
l manhOle at $40 ~ On
lamphole at S12 12 OO
q house connection chimneys at 81 A &C
Total cost $544 81
The greater cost of the Second street
