BID NO. 5, UNDER PLAN G.
Supply of 70 million gallons daily from
Rockaway River at Lower Montvllle, de-
livered into Bergen RESERVOIRS at III 1eel
DESCRIPTION OF WORK.
The supply will be drawn from the
dam being near S~tarkey's Wooden Mill.
This dam will be an earth embarrassment
with concrete core wall and will
way will be blasted in or found
ed upon solid rock at the end of
the dam. The elevation Of reservoir at
full water level will be 23S feet above tide,
and it will be drawn down to12l0 feet. u
will nave an area of 1929 acres. when full
and of III acres at low water level, and
over 80 per cent. of its area the depth Will
exceed s feet when full; over a large por-
tion the depth will exceed. SO feet. LIS
capacity will be u, 600, 000, 900 gallons. The
area of tributary water shed is 1873 square
miles, so that the reservoir will provide
enough storage to furnish 70 million gal
Ions daily.
by a conduit partly of steel pipe, partly of
masonry built open trench and then COW
cred and partly in tunnel.
The gate house at Lower MOntville Res
ervoir and at the entrance of the tunnel
will be so constructed as to permit the
water to be drawn from either 210, 220 or
230 feet elevation or t~hereabouts. The
tunnel through Hook Mountain will be of
a horseshoe shaped section equivalent tc
a circle seven feet in diameter, and the
hydraulic slope in. this and all masonry
conduits or tunnels will fall one foot in
each two thousand feet of length. AT the
eastern portal of the tunnel there will be
a gate house and thence there will be two
lines of steel pipe, the smallest internal
diameter of each being sixty inches and
the hydraulic gradient seven-tenths of a
foot in each thousand feet. Near Little
Falls these pipes will deliver into a ma
sorry conduit, and this and the tunnel
through First Mountain will have an aS-
gregate length of q, 900 feet, the internal
diamete being equivalent to a circular Z
feet in diameter, the section horseshoe
foot in each two thousand feet. Where the
masonry conduit crosses the Morris Canal
near Brookdale, it will be necessary to
slightly depress the grade of the con-
duit, and thus a head of perhaps five
feet of water will be put upon it. This
portion of the conduit will be lined with
steel, forming a steel pipe Z feet in diam
tance of about 100 feet. The masonry
portion of the conduit will terminate in
a short tunnel having the eastern portal
and a ~gateh0uSe near the nOrthernmoSt
corner of Franklin Township, Essex
County;
duit will be composed of two lines of
eter of sc inches, which will deliver into
Bergen Reservoir at 17 feet elevation.
The foundations across the meadows will
be formed to meet varying conditions and
give the most suitable construction in
each case, conforming to the specifica-
tons. The Passaic and Hackensack
Rivers will be crossed by either eight
lines of east iron pipe AZ inches in diam
eter, with flexible joints, four connected
with each steel pipe, or by carrying the
steel pipes through tunnel beneath the
river in a manner acceptable to the en-
