General Specifications TO accompany
proposals of II. ]. Reilly and others.
The following plans and general speci,
fcations are Intended to comply with all
the engineering requirements of revised
and amended Specification c, as. adver-
tised for proposals to pc submitted
lines of steel pipe of equal capacity to
Bergen reservoir The drawings accom-
panying these specifications are illlstra-
tive, showing the general features of con-
struction, but in any case where they do
not show all that is called for under
these specifications, the specifications are
to be accepted as final.
It is intended hat all structures herein
included shall be ample for the purpose
both as to capacity, durability and gem
eral workmanship, in az Of which re
prevail of the city's engineer during con-
struction.
GENERAL PLAN.
The water will be drawn from the
Rockawav River near Powerville, the in
lake to be at an elevation of 1876 feet.
The intake gate-house is shown on the
provided with at least two screen cham
accompanying drawings. and is to be
one intake chamber for each steel con-
duit, with a third chamber suitable for
the intake of a 48-inch steel conduit ad-
ditional when the same snail be required.
Each intake is to be fitted with sluice
gates from the screen chambers, and a
sluice gate for the mouth of each pipe
hence the water will be conducted to
a tunnel through First Mountain near
Upper Montclair by two lines of steel
pipe having an effective internal di-
under a hydraulic slope of 1.6 per thou
sand, under which conditions each pipe
will deliver z GOO. 600 gallons daily. or a
into said tunnel by a proposed chamber
of masonry provided with an opening for
a third pipe 4s inches in diameter and
excess of pressure upon the pipe lines.
The tunnel will be lined with brick laid

At its eastern. end a ~gate-house will
be provided with sluice gates for each
conduit, and a third openi1g. and slnice
rate suitable for an additional conduit

eastward to Bergen reservoir there will

difficult river crossings and the CROSSINGS
of the meadows. not only will the safety
of the whole system of works be much
greater thar if a larger pipe should he
employed. hut the expense of mainte-
nance for all future time will be mater
tally decreased.
Rockaway river above the intake will
nave a drainage area. of 118 square miles.
Its supplying capacity for the driest
period Known, such as occurred in 1881
and 1882 will be 100000 gallons daily,
and it will b noted that this estimate
IS at the rate of 666, 900 gallons daily per
city of Newark is drawn from an area
of 62.6 square miles, and in order to de-
liver the 50. 000.0 900 Gallons there estimated
to be available. the supplying capacity
must reach 100000. gallons daily per
square mile. This is sufficient to show
that our estimates are conservative, as
there is no reason for supposing that the
delivery from the P~eQuannocz water
shed will be any larger per square mile
thai from the Rockaway. It is pro
to draw from this watershed $4,000, 900
gallons daily, together with an additions
al rights therein which may be acquir-
ed by the contractor.
RIGHT OF WAY. A right of way
VIII be provided for pipe lines not less
than 80 feet in width from the intake
at Powerful to Passaic river at Belle
by the city. but from that point
eastward to Bergen reservoir, the con-
tractor is to have the us or the right of
way owned by the city, including the
right to lay pipe through the streets by
the most direct route to connect with
Bergen reservoir.
TIME TO COMPLETE. The con-
fractpr will undertake. to cOmDlote the
