The reservoir sites must be thoroughly
cleared and prepared, TO the end that the
water flowing therefrom shall at all times
be pure n wholesome, and free from
harmful or deleteriouS matter or sub
stance. All trees, dead and fallen timber,
logs, SaplingS, underbruSh, vegetation,
stumps, posts and other material must
be thoroughly grubbed and removed, and
the whole of the material stacked and
burned or otherwise disposed of outside
of the reservoir limits, and the total area
must be raked clear of all refuse, dead
leaves, vegetation ard other rubbish, and
thoroughly cleaned and prepared in every
way, and all slopes properly protected, so
as to be fit for the purpose intended be-
fore water is let in the reservoirs,
1t is not hereby intended that healthy
| upland sod or soil must be removed. but
the removal of mud or swamp soil con-
tanning accomplishing vegetable matter
may be required by The Engineer.
II any artificial lakes or ponds where
the water surface has been extended by
| the flooding of adjoining lands, shall be
used as reservoirs, they shaH inst be
drawn down and theiEs beds properly pre-
| pared, in accordance with these Specl-
before being put i'll service, II
the Engineer shall SO direct.
There shall be a clear space around the
water-line of the reservoirs, and not less
lIhan sixty feet in width, and additional
space where it may be needed, which is
to be included in the conveyance OF the
ment will not be enforced for the entire
water~line in case Lake Hopatcong or
IGreenwood LAX are offered as reservoirs,
provided tina the bidder specifies in his
| bid what portions Of the margins of those
lakes he wishes excepted therefrcIn, and
provided further that he succeeds IN pre-
venting harmful pollution ofthe water by
a proper exercise of the powers herein
| placed at his disposal. or by other means.
The depth Of reservoirs shall in all cases
exceed eight feet below the full water
level throughout seventy-f1ve per cent. OF
the entire area of the reservoir.
The reservoir Dams may be either OF
masonry or earth entertainments, as. may
be best suited to the differentl localities.
| They shall be of sufficient height and
| strength, of the best adapted shape, and
built in the most substantial and thorough
manner, on properly prepared foundations,
| with the necessary effluent pipes, gate
houses, with gate-chambers vaults,
| gates, valves, screens. and alb other APP
planes and appurtenances proper fer the
purpose intended, with the necessary
slope walls, by-Wash, waste-weiss, blow
| offs, drains and waste pipes, and they
| shall be provided with such sufficient
space or area of land along the foot and
side as MAY be necessary to protect the
same. and shall be fenced where required.
In case there should not exist q public
road, or roads leading. to ana permitting
! access to the reservoirs; where located;
necessary lands and right of way shall
be acquired and furnished to give such
CONDUIT CAPACITY.
The carrying capacity of all rivetea steel
| conduits will be determined by the kut-
ter formula, taking the co-etieient n to
/ equal .016 Sixteen th~ousandthsl. me
| smallest interior. diameter OF the shell as
constructed shall be considered to be the
diameter of the pipe.
The carrying capacity OF All mason"
| onduits or tunnels will be determined ny
| the Kutter formula, taking the co-etfiolent
/ n to equal .014 fourteen t~housandths) for
brick work. concrete or ashlar masonry
lining, and .0lS eighteen thouSandths) Tor
rubble lining. All such masonry tunnels
or d shall be capable of delivering
the full supply called for when ~discharg-
ing with a free upper surface, the water
surface not to be higher than one foot
! below the top of the arch.
The head to be used for computing the
capacity of the conduit shall be the I'LL
ference between the low water level, or
| the bottom elevation of the available
capacity of the reservoir or reservoirs at
the points of intake, and the height or
| elevation of delivery at the points OF de-
| livery designated in these specifications.
RIGHT OF WAY.
| The right of way for conduits snail m
| no case be less han forty feet in width,
| and shall be sufficient to enable the City
in case of purchase fully to protect the
pipe or pipes laid therin. and to maintain
and repair the same. The right OF way
| shall extend from the reservoir or reser-
voirs at the point or points OF intake 70
the points of delivery. Each conduit shall
be constructed on one and the same SIDE
| Thereof throughout, and 50 as not to oc-
cupy more thereof than is necessary.
| Where the City furnishes right of way
| over lands which 1t now owns, the con.
| duits shall be laid on hat part thereof
! DESIGNATED by the Engineer.
LAYING OF CONDLITS.
The conduits shall he laid ia the best
and most thorough manner on true grade
! lines on a bed or foundation properly pre-
| pared. and where necessary. to procure
! such foundation, on piling. The curvature
I Of the pip shall in no case be sharper
than ten degrees. Cast iron pipe with
flexible Joints or other devices accept
able 10 the Engineer may be used at
stream crossings. If steel pipe is used
| where the stream exceeds % feet in width.
FIT must have a thickness OF an
| inch greater than that required for the
same pressure elsewhere.
Where pipes are laid in excavation the
top OF the pipe shall be covered by at
| least three feet of earth. and the pines
| shall be so placed as to bring all the
longitudinal seams on the upper quarter
of the circumference
Wherestae pipe is to be laid across rock,
| swamp or meadow. It may be above the
| surface of the ground, but must be COW
! cred with satisfactory earth. sand or
| gravel. so that it shall everywhere have
| at least three feet of such covering. In
| ali sneh cases, and on all Embellishments
| the contractor must sow Grass seed or
sod, or otherwise protect said embank-
| ments. Necessary culverts and other con-
sfructions must be made to secure. the
Representatives. OF the adjoining
CONNECTIONS.
Where two steel pipes are laid they are
