Cleanup shall consist of the restoration of the construction area to its
original condition or better. Excess materials, roots, and debris shall
be removed. Driveways and shoulder, shall be restored. Valve boxes shall
be checked for proper seating of ilds and satisfactory clearance for in—
sertion of operating wrenches. Valves shall be checked for satisfactory
operation and left open unless specifically 'esignated to be normally
closed. Bonnets and pacKir; glands shall be tight enough to not leak, but
not so tight as to make operation difficult. Fire hydrants shall be operat—
ed to assure that unobstructed flan is obtained, and that drain valves
operate properly. Road surfaces and shoulders shall be restored to the
satisfaction of the responsible city, -ounty, or state official.
:leanup shall also be defined to include the furnishing of satisfactory
evidence that bills for materials and labor, and that cla: is of the Tax
Divisfon and the Department of Labor and Industry have been satisfied.
Specifications
The Contractor shall furnish the labor and equipment necessary to pe:forn
the test, including pressure pump, an accurate pressure gauge, and the
valves, fittings, pipes or hoses as may be required. As may be necessary
he shall also provide corporation cock connections to the mal%s for the
injection of sterilizing solution, or water for the pressura test, or for
release of entrapped air.
After filling the pipe line and releasing trapped air, '.he line should be
checked for leaks at nor:wl pressure, and valves checked for proper
operation and opined or closed to isolate the section to be tested. There-
after, the pressura shall be incre.,sed by p.mping clean water into the lire
" until 150 psi is obtained. This pressure shall be maintained for a period
of one hour and the quantity of water used during the test shall be deter-
mined. The allowable leakage shall not exceed 1/2 gallon per hour per inch
diameter per 1000 feet of pipe under test.
The Engineer or his representat've sha.1 be notified a day ahead of the
test and shall be present whoa chc pressure test is made.
2.17 Crossings of Paved Street,,,
Oil mat., asphaltic concrete, and cement concrete pavement surfaces to be
opened for trenching stall be line cut at a point not ' _...s than 6 inches
back f--m the edge of the '.reach on each =ide. Asphalt. . pavement shall
be cut with a N..a„matSc spade tool at an angle of about 3CP from vertical.
Concrete pavement shall be cut by sa-.ang a groove to a depth of 2 inches,
or by drilling holes spaced at approximately 4 - 6 inches to secure a
reasonably smooth breaking :ine with a "skullcracker" ball or "hydro-
hammer". The face of the cui: shall be approximately vertical. Slabs of
concrete Sess than three feet wide to the neareet pavement joint or crack
shall be removed.
2.18 Bituminous Surfacing
Where the existing pavement is an oil mat, light bitumincus surfacing,
or asphaltic concrete without a cement concrete base, the pavement shall
be replaced with 3 inch of hotmixed, hot-laid asphaltic concrete on top
of 6 inch of 3/4 inch minus slze compacted crushed rock. The asphaltic
concrete mixture, and placinn, shall conform to State Highway Department
specifications for Class I-1, Clasc C. Prior to placing the asphaltic-
con.rete the edge of the previous pavement ahall be cleaned and brushed
with a thin coat of cut-back asphalt. The material shall be compacted
by rollino eohile hot with addition or removal of material as necessary
to secure a smooth, riding surface flush with the existing pavement.
Traffic shall be excluded until the mixture has cooled and set.
2.19 Cra'iel Surfacing
Trench within the traveled way In unpaved streets shall be compacted by
mechanical tamping, or vibration, and shall have a topping of 3 inch
crushed rock, 3/4 inch minus size.

Specifications
2. Placement of dry chlorinated lime,(HTH. Perchloren,etc) throughout ty,e
pipeline as it is constructed. Use of this method will be permitted only
if the pipe line is dry, if the line will be filled within two days after
first hypochlorite is placed, and if the direction of flow while filling is
uphill. In any event,the rate of filling must be slow to avoid washing the
powder, and chlorine, to one end of the pipe.
After introduction of the nhlorine and filling of the line; the sterilization,
agent shall be left for at least three hours but preferably 24 hours. How-
ever, strong chlorine solution shall not remain in the line for more than
five ciys. If the line appears reasonably tight after fillingr the line
pressu:e test may be performed concurrently with sterilization.
Following completion of the sterilizing period, the line shall be flushed
at a rate 'If flow sufficient to remove foreign materials, dirt and stones
that might 'save gotten into the pipe during construction, and to remove the
chlorinated water. Where a sufficient flow for proper flushing might cause
flooding or erosion difficulties from one hydrant, use of several hydrants
is suggested. Valves at connections to existing lines shall be opened only
when the pressure In the new line Is less than in the line connected to.
In other words, a hydrant or other relief on the new line shall be open so
that the flow will be from the existing pipe and sterilizing solution will
not be carried into the existing system.
After the line is sufficiently flushed, the Engineer will take bacterio-
logical samples to determine the effectiveness of the sterilization. The
cork shall not be acceptable, nor shall anv flow be permitted from the new
lines to service connections nor to other parts of the water system, until
a satisfactory bacteriological test has been obtained.
Where the . me methods of sterilizing are impractical for small portions
of the work, as at tees cut Into existing operating lines, the following
methods shall be used.
1. The area of the work shall be sufficient for ampl, orking space. shall
be safe from cave-ins, and shall have no free water in the work area.
2. The work shall he precut and fitted as much as possible before assembly.
3. The interior of pipe, fittings, valves, etc., to be installed shall be
washed clean and then sterilized as much as possible by swabbing, sloshing,
flcoding or other, with strong chlorine solution.
4. Thereafter, the work shall be conducted under as clean conditions as
obtainable. Support parts on planks, change to clean gloves, etc.
2.16 Z=U=Lj1d
The watertightness of the pipe line installed shall be demonstrated rdefore
the work may be considered for acceptance.

Specifications
2.13 Thrust Blocking
Ali elbows, tees, and crosses shall be blocked against the kinetic thrust
of the water flaw by poured-In-place concrete equal ir thickness to the
outside pipe diameter and extending back to undisturbed earth. The area
of the concrete block bearlp- against the undisturbed trench well shall be
sufficiently larg, ti I-aep the thrust bearing pressure well below the safe
valve for the specific soil condition. Concrete shall he 1s3:5 mix or
better, and shall not extend over the ,joint e,ds of the fittings.
Hydrants, and plugs or caps on dead ends of unused braiches of tees and
gate valves, shall be blocked against hydrostatic pressure by concrete
blocking to solid earth, unless they are secured In place by flange
connections, Lugs and bolts, or shackle zoos. Blocking with timber or
ordinary rocks will not b7 acceptable. Blocking, shall be placed so that
it will not interfere with later extension of the pipe line.
The water line pressure test shall not be made until at least two days
have elapsed since the last thrust blocking in the section to be tested
was placed.
2.14 Setting Hydrants
Hydrants shall be set at the locations designated on the plans or de-
termined by the E•ngbmwa In the field. The Hydrant shall be set plumb
with the hose nozzles not less than 12 inches above ground level. Where
impractic..l to ase poured concrete thrust blocking behind the line tee
and the hydrant, the thrust shall be taken by shackle rods or flanged
connections.
Hydrants set in clay, or other impervious soil,shali have a drainage
pit two feet in diameter and three feet deep excavated bellow it and
backfilled with coarse sand or or-vel +^ p,rirt six inches ?hove the
hydrant drain opening.
Hydrants shall be painted one cu,i et tirst lraue enamel pint of the
color conforming tr the local fire department standard. The space
within 5 feet on front, aryl sides of hydrants shall be cleaned of brush
and graded to a neat, smooth surface.
2,15 S&erilization
As sac clons of pipe are constructed, and before pipe lines are placed
In service, they shall be sterilized in conformance with the require-
ments of the Stare Health Department,
Sterilization shall be done by one o" the following methods (in order of
preference) to secure a concentration in the pipe of 30 to 50 ppm avail-
able chlorines
1. Injection of chlorine-water solution from gas chlorinating apparatus
through a hydrant or corporation cock at the beginning of the section to
be sterilized, with water exhausting through a hydrant at the end of the
section. The rate of flow an' the rate of chlorine feed shall be measured
and adjusted to secure the desired chlorine concentration..

Specifications
2.10 jrgpch Excavation
The trench shall be excavated on a true line at the location shown on the
plans and as staked by the Engineer. Width of trench shall be no greater
than necessary to permit access for jointing and backfill tamping. Normal
depth cf cover shall be 36 inches. All known underground obstacles are
shown oi, the plans with instructions given where an altered depth is anti-
cipated. Where inforadtion was not obtainable as to depth of the obstacle,
such fact is noted and it shall be the respunsibility of the Contractor to
uncover the obstacle in advance of trench excavation to determine the proper
grade necessary to miss the obstacle. Where a conflict occurs with surface
drain lines or inlets,they shall be removed and replaced after completion of
the water line.
The trench shall be excavated to a flats or curved bottom with a straight
grade between pipe connections. High spots, rocks, and other uneven support
shall oe removed prior to placing each pipe length. Blocking under the pipe
will not be permitted.
Concrete pavement and asphaltic surfacing excavated shall be hauled to waste.
i,. Contractor shall adequately support and brace utility poles and underground
utility pipes.
2.11 Trench Backfill
As pipe is laid, it shall bo additionally supported by p1,zing suitable
excavated soil under and adjacent to the pipe to the level of the mid-
diameter. The remainder of the backfill, except as specified below for
trench in roadway shall be machine placed and compacted by travel of
rubber tired machinery along the trench.
Backfill at important road or hi,hway crossings shall be with clean pit run
sand, mechanically tamped or vibrated in 12 inch layers to sufficient density
to prevent subsequent settling. The same requirement of mechanical vibration
or tamping with native material backfill shall apply where trench is in the
traveled roadway. Backfill shall follow immudiately after pipe laying,
particularly in heavily traveled streets. If i^imediate replacement of
surfacing is impractical, the top three inches of the trench, when within the
traveled way, shall be filled temporarily with crushed rock until permanent
replacement of the surfacing can be accomplished.
For specifications regarding Highway crossing — See Attached Permit No 2769,
2.12 Handling Pipe
Pipe shall be handled carefully to avoid overstraining it and damage to the
coating or lining. At trench side it shall be kept out of drainage ditches
and otherwise placed so that water and dirt will not be carried into the pipe.
Pipe and fittings shall be lowered into place in the trench by protecting
slings or snubber ropes.
The replacement of pipe found defective from handling or any other factor and
the repair of coating, or lining damage in transit or in handling shall be the
responsibility of the contractor.
