the storage reservoirs proposed, the aoca-
Which are given herein, and they are also
designated upon a map or plan annexed
to this proposal.
The gathering grounds selected for this
proposal are OF sufficient area to deliver
srhe quantity of water called for without
exceeding a daily draft of 666, 094 gallons

the larger reservoirs are placed and pro-
porttoned to a capacity 10 impound ana

proposed to supplement this shed by add

south end of Copperas Mountain. With
this added territory the water she'd will

The area of the lake thus formed win
approximate to 800 acres. and its capacity

Route and Sizes of Pipe-It is proposed
that of the total supply eventually re-
CURED of fifty million gallons, twenty-five
millions shall be taken from Port Dram
| Intake and the balance from Beach Glen
and other sources east of Beach Glen. The
condui viii be laid at once from Port
Dram through the Pockaway Valley to
Beach Glen with a capacity Of IS million
~gallonst from Beach Glen re Jersey City

gallons.
From the Port Dram Intake the water
will be carried across the valley Of Green
| Pond or Burnt Meadow Brook, about 1000
feet. by a 4S-4nch steel pipe, carried on
piers Of masonry, and then
into q 4S-inch circular conduit, with a
grade Of about > feet per mile passing in
a short tunnel through the hill north of
Dover thence by a A0-ineh pipe to within
two miles OF Beach Glen; thence by W
miles of 33-ineh to Beach Glen connection;
thence by a 5-fnch pipe. with a capacity
of 50 million gallons per day to the head
of the falls of Boonton. The size of
