A. General Provisions The specifications contained herein, together with
i' Oregon Department of Environmental Quality and Federal Environmental
Protect.' .i Agency standards and any other applicable requirements of the
{ Agency, shall govern the char•-7cter and quality of material, equipment,
installation andconstructionprocedures for main line sanitary sewer work
of gravity flow systems.
1. Scheduling
a. Sequence o Operations. The Contractor shall plan construction
j work and execute his operations with a minimum of interference
II with the operation of the existing Agency facilities. It may be
necessary to do certain parts of the construction work outside
normal working hours in order to avoid undesiranle conditions,
and it shall be the obligation of the Contractor to do thio work
at such times. This scheduling, however, is subject to the
Agency's approval and does not relieve the Contractor from making
his work available to inspection.
Page 15
The Contractor shall notify the Agency at least 48 hours (two
working days) prior to any Agency inspection. The Contractor
shall, in addition to regular inspection fees, reimburse the
i Agency for all costs incurred by Agency for inspections performed
on Saturdays, Sundays, holidays or during other than normal
Agency work hours. Connections between existing work and new
work shall not be made until necessary inspection and tests have
been completed on the new work and it is found to conform in all
respects to the requirements of the plans and specifications.
t
b. Proqress of Construction. Construction shall proceed in a
systematic manner that will result in a minimum of inconvenience
to the public. The Contractor shall limit his operations to a
small length of work are per crew. Unless given written
permission from the Agency, the trenching equipment at no time
shall be further than 300 feet ahead of the pipe-laying crew.
The trench shall be backfilled so that no section of trench or
pipe is left open longer than 24 hours. Trenches located in a
right-of-way shall be completely backfilled before the Contractor
leaves the site each day.
Cleanup of all construction debris, excess excavation, and excess
materials, and complete restoration of all fences, mail boxes,
ditched, culverts, signposts, and similar items shall be
completed immediately following the final backfill of the trench,
T or sooner, if so directed by the Agency.
2. Preservation, Restoration, and Cleanup
a. Site Restoration and Cleanup. The Contr;�ctor shall keep the
premises clean and orderly at all times during the work and leave
the project free of rubbish or excess materials of any kind upon
completion of the work. During construction, the Contractor
shall stockpile the excavated trench materials so as to do the
least damage to adjacent lawns, grassed areas, gardens,
shrubbery, trees, or fences, regardless of the ownership of these
ureas. All excavated materials shall be removed from these
ar;Nirzs, and these surfaces shall be left in a condition equivalent
to their original condition and free from all rocks, gravel,
boulders, or other foreign material. Thi Contractor shall
replace topsoil areas over all trenches with a minimum finished
depth of twelve (12) inches. All existing drainage ditches and
culverts shall be reopened and graded, and original drainage
restored. All damaged irrigation and house drainage pipe, drain
tiles, sewer lateral, and culverts shall be repaired
expeditously. Within 500 feet of pipe laying and backfilling
operations in any section, the Contractor shall rake and drag all
distrurbed areas and leave there free from rocks, gravel, clay, or
any other foreign material and ready, in all :~espects, for
seeding. The finished surface shall conform to the original
surface and shall be free-draining, free from holes, rough spots,
or other surface features detrimental to aseeded area.
All areas distrubed by the Contraztor's operation inside
dedicated rights-of-way or easements shall be fertilized and
reseeded or planted.
Page 16
i "
I
Areas outside of the easements or rights—of--way which are
distrubed by the Contractor's operations shall be graded and
reseeded in a method acceptable to the property owner in
question. The Contractor shall obtain a written release from
s such property owners prior to final acceptance of the work by the
Agency.
b. Street Cleanup. The Contractor shall clean all spilled dirt,
gravel or other foreign material caused by the construction
operations from all si:reets and Iroa1:AJ at- the conclusion of each
day's operation. Cleaning shall be by grader and front--end
loader supplemented by washing with water, power brushing, and
� . hand labor, unless otherwise approved by the Agency.
Within five (5) days after completion of all paving and gravel
fshoulder resurfacing, the Contractor shall remove all dirt, muss,
rock, gravel, and other foreign material from the paved surface.
f c. Dust Prevention. During all phases of the work, the Contractor
shall take precautions to abate any dust nuisnace by cleaning up,
sweeping, sprinkling with water, providing an oil dust preventive
treatment, or other means as necessary to accomplish results
satisfactory to the Agency. Dust Prevention measure shall be
continous until final acceptance by the Agency.
d. Preservation of Irrigation and Drainage Ditches. The Contractor
shall arrange schedules so that construction will not interfere
with the irrigation of cultivated lands or pasturelands.
Construction may proceed during the irrigation season provided
the Contractor constructs, at his own expense, such temporary
irrigation ditches, turnouts, and miscellaneous structures
acceptable to the owner of the land in question which shall
permit the land to be irrigated by others during construction.
Following the backfill of the trenches, the Contractor shall
6 ` restore all irrigation and storm drain ditches destroyed,
damaged, or otherwise modified during construction to a condition
equivalent, in the opinion of the Agency, to the condition of the
f ditch before construciton. Ditches so constructed shall be built
in their original locations.
e. Stream and Creek Crossings. The Contractor shall comply with all
provisions of the permits required by the Oregon Division of
State Lands and the U,S. Army Corps of Engineers.
Before any work may be performed in any stream, the method of
! operation and the schedule of such work shall be Approved in
writing by the Engineer. Work within major streams shall be
scheduled to take place as specified in the ,applicable permits
for such work, and once started, shall be completed without
interruption of the work. Mechanized equipment shall enter
streams only when necessary and only within the immediate work
s
area.

course of the work. Although maps and information regarding
underground utilities should be obtained from the utility owning
and operating such utilties, the location of such utilities is
not guaranteed. A minimum of forty-eight (48) hours' notice
shall be given to all utility officers which may ne affected by
the constructon operation, Should services of any utility be
interrupted due to the construction operation, the proper
authority shall be notified immediately.
fb) Protection. The Contractor shall exercise all due care in
protecting property along the route of the improvement. This
protection shall include, but not be limited to, trees, yards,
t fences, drainage lines, mail boxes, driveways, shrubs and lawns.
i If any of the above have been disturbed, they shall be restored
f
to as near their original condition as possible.
4. Surv.eyins
a) Permanent _survey markers. The Contractor shall not disturb
permanent survey monuments, property corners, stakes or bench
marks without consent of the Engineer. It shall be the
responsibility of the Contractor to protect such survey markers.
Survey markers which are disturbed or lost shall be replaced by a
registered land surveyor.
1) When a change is made in the finished elevation of the
pavement or any roadway in which a permanent survey
monument is located, the monument cover shall be adjusted
to the new grade.
5, Railroad Crossings
a) General. Crossings of railroad rights-of-spay shall be done in a
manner which conforms with the requirements of the railroad
having jurisdiction. If any bonds and/or certificates of
insurance protection are required, they shall be furnished by the
Contractor or Croner to the railroad company concerned with the
Agency as an additionally-named insured.
b) Permits or Easements. Actual permits or easements for such
'- crossings will be obtained by the Owner and all the teems of such
permits or easements shall be met by the Omer and Contractor.
In some locations, casing pipe may be required by the railroad.
8. Trench Excavation and Backfill
1, Definitions
a) Trench Excavation. The removal of all material encountered in
the trench to the depths shown on the plans or as directed by the
Engineer. Trench excavation shall be classified as either common
Fade 18
14,
1
or rock excavation. "Common excavation" is defined as the
removal of all material which is not classified as rock
excavation. The term of "rock excavation" shall be understood to
indicate a method of removal and not a geological formation.
Rock excavation is definited as the removal of material which
cannot, in the Engineer's judgement, be reasonably excavated with
equipment comparable in terms of machine weight and rated
horsepower to the units indicated in Table 1. Additionally, rock
i._ excavation is the removal of material requiring the use of
� drilling and blasting and g'ruinier—•oper'atau rock brcaUnn,
equipment, Boulders or concrete pieces encountered in the trench
excavation and larger than 112 cubic yard in size shall be
classified as rock excavation if any of the aforementioned
excavation methods are, in the judgement of the Engineer,
required to remove this material.

b) Trench Foundation. The bottom of the trench on which the pipe
bedding is to lay. The trench foundation provides the support
for the pipe.
c) Pure fed ina. The furnishing and placing of specified materials
on the trench foundation so as to uniformly support the barrel of
the pipe.

` cit Pipe _Zone. The full width of the trench and from a point above
the top outside surface of the bell of the pipe to the trench
foundation.
e) Sprincr Line. Half-way up the sides of the pipe when it has been
laid in the excavation.
f) Trench Backfill. The furnishing, placing, and compacting of
material in the trench between the top of the pipe zone material
and the bottom of the pavement base rock, ground surface, or
surface materials es directed.
2, M4teriais
a) Trench Foundation. Trench foundation shall be native material in
all areas except where ground water or other conditions exist
and, in,the opinion of the Engineer, the native material is such
that it cannot support the bedding and pipe. In those
conditions, _excavation shall be included to additional depths as
t t
required and backfilled with crushed aggregate.
Page 19
i
b) Pipe Bedding. Pipe bedding material shall be clean crushed rock
with a maximum size of 3/4-inch, uniformly graded from coarse to
fine or as approved by Engineer.
c) Pipe Zone. The pipe zone material shall consist of bedding
i material, or native material, i.e. , earth, gravel, rock, or
combination thereof. It shall be free of humus, organic matter,
vegetative matter, frozen material, clods, sticks: and debris and
shall present no isolated points or, areas, or larger stones which
would cause fracture or denting of the struCtUre or subject it to
undue stress. All pipe zone materials shall be subject to the
Engineer's approval.
I-
3. Construction
a) Excavation
1) �Iearincx the Right-af-way. When clearing the right-of-way
is necessary, the clearing shall be completed prior to the
1 start of the trenching. Brush shall be cut as near to the
surface of the ground as practicable and removed to a
disposal site approved by the Engineer. The Contractor
shall observe all federal, state and local laws relating to
fire permits and burning materials. Under no condition
shall excavated materials be permitted to cover brush prior
to clearing and disposal of such brush. Excavated
I, materials shall be placed at locations and in such a manner
that it does not create a hazard to pedestrian or vehicular
traffic, nor interfere with the function of existing
drainage facilities.
2) Open Trench Limit. The length of the trench excavated
shall always be kept to a minimum. The Engineer shall be
the judge of the amount of open trench allowed based upon
work conditions of the area. In normal cases, the open
trench length shall not exceed 100 feet. Related trench
construction such as pavement, road gravel, concrete
restoration, etc., shall be completed within 800 feet of
the open trench limit unless otherwise authorized
e
3) Trench Width. It is the intent of these specifications
that the trench width at the surface of the ground be kept
to a minin,im necessary to install the pipe in a safe
manner. In all cases, trenches must be of a sufficient
width to allow for shoring and to permit proper joining of
the pipe and backfilling of material along the sides of the
pipe. The minimum trench width in the pipe zone must
provide a clear working space of six inches outside the
maximum outside diameter of the pipe.
No maximum width of trench at the top of the pipe will be
specified herein. When required by design, the maximum
trench width shall be shown on the plans. If the maximum
width shown is exceeded by the Contractor without written
authorization, the Contractor• will be required to provide
pipe of a higher strength designation, a higher class of
bedding, or both, as approved by the Agency.
Page 20
Excavation for manholes and other structures shall be wide
enough to provide a minimum of 12 inches between the
structures" surface and the sides of the excavation. The
Contractor shall confine the top width of the trench to
rights—of—way or easements. Special written agreement to
j extend the width may be made with the affected property
owner provided such agreement is first approved by the
P..
Engineer.
4. Rock Excavation. Where the bottom of the trench encounters
ledge ,rock and/or boulders and large stones which meet the
definition of "rock excavation", rock excavation shall be
performed to provide six (S) inches of clearance to each
side and below all pipe and accessories. Excavations below
subgrade in rock shall be backfilled to subgrade with
approved bedding material and thoroughly compacted. The
Contractor shall provide approved types of tools and
devices necessary for loading and using explosives,
blasting caps, and accessories and shall conform to and
obey all federal, state and local laws that may apply and
to directions that may be given from time to time by the
Engineer relative to the handling, placing, and firing of
explosives. When blasting rock in trenchs, the Contractor
shall cover the area to be shot with blasting mats or other
�. approved protective material that will prevent the scatting
of rock fragments outside the excavation. The Contractor
shall give amply warning to all persons within the vicinity
before blasting; station people; and provide signals of
I dange in suitable places to warn people and vehicles before
f firing any blasts. The Contractor shall fire all blasts
with an electric blasting machine which shall be connected
to the circuit immediately prior to the time for firing and
f only then by the person who will operate the blasting
machine.
b) Installation
1) Shorin The Contractor shall provide alp
materials, labor, and equipment necessary to
adequately shore trenches to protect the work,
existing property, utilities, pavement, etc. , and
,. to provide safe working conditions in the trench.
That portion of cribbing or sheeting extending
below the spring dine of rigid pipe or below the
crown elevation of flexible pipe, shall be left iri
place unless satisfactory means of reconsolidating
bedding or side support, disturbed by cribbing or
sheeting removal, can be demonstrated. If a
t moveable box is used in lieu of cribbing or
sheeting and the bottom cannot be kept above the
spr•irg line of rigid pipe or the crown elevation of
flexible pipe the bedding or side support shall be
carefully reconsolidated behind the moveable box
prior to placing backfill. The use of horizontal
strutting below the barrel of pipe, or the use of
pipe as support for trenchbracing, will not be
permitted.
Page 21
2) Dewatering,. The Contractor shall provide and
maintain ample means and devices with which to
promptly remove and dispose of all water entering
the trench excavation during the time the trench is
being prepared for the pipe laying, during the
laying of the pipe, and until the backfill at the
pipe zone has been completed. Groundwater shall be
controlled such that softening of the bottom of
excavations or formation of "quick" conditions or
"boils" during excavation shall be prevented.
Dewatering systems shall bc designed and operated
so as to prevent removal of the natural soils and
so that the groundwater level outside the
excavation is not reduced to the extent that would
damage or endanger adjacent structures or property.
3) Trench Foundation. When, in the judgement of the
Agency, the existing material in the bottom of the
I trench is unsuitable for supporting the pipe, the
1 Contractor shall excavate below the pipe as
directed. The Contractor shall backfill the trench
to subgrade of the pipe bedding with trench
i , foundation material over the full width of the
trench and compact in layers not exceeding six (5)
inches deep to the required grade.
R) Pipe Beddinn . Pipe bedding consists of leveling
the bottom of the trench on the top of the
[ foundation material and placing bedding material to
the horizontal centerline of the pipe unless other
wise specified. The Contractor shall spread the
bedding smoothly to the proper grade so that the
,.: pipe is uniformly supported along the barrel and
excavate bell holes at each joint to permit prooer
assembly and inspection of the entire joint.
Bedding under the pipe shall provide a firm,
unyielding support along the entire pipe length.
Particular attention shall be given to the area
from the flow line to the horizontal centerline of
the pipe or top of bedding to ensure that firm
support is obtained to prevent any lateral movement
of the pipe during the final backfilling of the
gripe zone, Pipe bedding shall be placed the full
width of the trench.
5) Grade. The Contractor shall excavate the trench a
minimum of four (Q) inches plus the pipewall
thickness below the grade shown, or as established
t by the Engineer. The subgrade upon which the
bedding is to be placed shall be firm, undisturbed,
t and true to grade. If the trench is
over-excavated, the Contractor shall restore to
grade with material of the type specified for pipe
bedding and place the material over the full width
of the trench.'
Page 2

6) Backfill. Backfill shall not be placed in the
trench in such a way as to permit free—fall of the
material until a minimum of two (2) fent of cover
is provided over the top of the pipe. Under no
circumstances shall the Contractor allow sharp,
17 heavy meterials to drop directly onto the pipe or
I - pipe zone material around the pipe. If the
required compaction density has not been obtained,
the Contractor shall remove the back--fill from the
trench and recompact. This process shall be
repeated until the Contractor has established a
17 procedure that will provide the required field
detISit;. rho Contractor will then be permitted to
proceed with backfilling and compacting the
remainder of the pipeline under the approved
compaction procedure. With approval of the
Engineer, the Contractor may substitute water
settling as an alternuite compaction method. Water
settling shall be done only with approved jetting
equipment and methods. Water settlement shall not
relieve the Contractor of the responsibility for
compaction of trench backfill as specified herein
for standard compaction methods. The location and
extent of trench water settling will be determined
by the Engineer. The Contractor shall backfill the
trench as specified to a point level with or
t ; slightly above the required grade to allow for
settlement. After all structures are completed and
j all subsurface utilities have been restored to
E their original condition, the Contractor shall
-
place water in the trench section in such
quantities and in such a manner that all portions
of the backfill for the entire trench depth become
-" saturated. The Contractor shall determine the
procedures and provide the quantity of water
required in every case to effect compete water
settlement of the backfilled materials. Under no
circumstances will the jetting pipe be inserted
closer than two (2) feet above the top of the
pipeline. Any subsequent settlement of the trench
during the warranty period shall ho considered to
be the resultof improper water ' settlement or
compaction and shall be promptly corrected. The
.= Granular Backfill within four (4) feet of finished
grade shall be compacted to not less than
ninety-five (95x) -percent 'relative compaction as
determined by Method A of AAWSHTC T180. Backfill
more than four (4)_ feet from finished grade shall
be compacted to not less than ninety (90%) percent
relative compaction. Tests to determine compliance
with the compaction requirements shall be provided
t
as required by the Agency,:

air test must be capable of resisting the internal pressures and
must be securely braced, if necessary. All air testing equipment
must be placed above around and no one shall be permitted to
enter a manhole or french where a plugged line is under
pressure. All pressure must be released before the plugs are
removed. The testing equipment used must include a pressure
. relief device designed to relive pressure in the line under test
at 10 pi or less and must allow continuous monitoring of the test
pressures in order to avoid excessive pressure. The Contractor
shall use care to avoid the flooding of the air inlet by
infiltrated ground water. The contractor shall injuect the air
at the upper plug if possible. Only qualified personnel shall be
permitted to conduct the test.

i
t
a) Clean the lines to be tested and remove all debris where
j noted.
b) The Contractor has the option of wetting the lines prior to
testing.
C) Plug all open ends with suitable test plugs; brace each
ii plug securely.
1 , d) Check the average height of ground water over the line.
The test pressures required shall be increased 0.433 psi
for each foot of average water depth over the line.
e) Add air slowly to the section of system being tested until
the internal air pressure is raised to 4.0 psig greater
than the average back pressure of any ground water that may
submerge the pipe.
f) After the internal test pressure is reached, at least two
(2) minutes shall be allowed -for the air- temperature to
stabilize, adding only the amount of air required to
maintain pressure.
g, After the temperature stabilization period, disconnect the
i air supply.
l
r h) Determine and record the time in seconds that is required
for internal air pressure to drop from 3.5 psig to 2.5 psig
greater than the average back pressure of any ground water
t, `hat may submerge the pipe.
i) Compare the time recorded with the time required as
determined hereinafter.
4) Acceptance. The system shall be considered acceptable when
tested as described above if the section under test does not lose
.l air at a rat; greater than 0.003 cfm per square foot of internal
pipeline surface, or 2 cfm, whichever is greater. If a line
fails to meet these requirements, the Contractor shall repair or
replace all defective materials or workmanship. This
specifications shall also be considered as satisfied if the time
as measured by the above-described method is not less than the
time as computed according to the following procedure:
a) Record the diameter in inches and the length in feet of all
pipe in the section to be tested, including the service
innections, in a table similar to the one shown below:
Diameter Length !{ c =
`^ (Inches) (Feet) 0.01id2L 0.0003882dl
TOTAL.
TIME REQUIRED BY SPECIFICATION — SECONDS
.= ACTUAL TIME AS DETERMINED BY TEST SECONDS
Page 35
t
B) Using the nomograph at the end of this section, place a
straight edge from the "d" column (diameter in inches) to
the "L" column (length in feet). Read the corresponding
4 "K"" and "c" valves and record them in the table.
C) Add all values of "K"" and all values of "C" for the section
being tested.
d) If the total of all the "c" values is less than one, the
time required by the specifications shall be the total of
all the "K" values.
F-
e) If the total of all the "C" values is more than one, the
time required by the specifications shall be found by
dividing the total of all the "V values by the total of
all the "C" values. The quotient is the time required by
the specifications. To make this division with the
nomograph, use the scales "C" and "K"" and read the quotient
(time) from the "t q" scale.
f) In the event that the "D" and "L" values for a particular
f section of the system do not fall within the limits of the
nomograph, the values "K" and "C" may be computed from the
following equations: "V = 0,OO1ld2L; "C" = 0.00036G2dL.
ca) Deflection Test for PVC. In addition to air testing and
when required, sanitary sewers constructed of PVC pipe
shall be deflection—tested not less than 30 days after the
trench backfill and compaction has been completed, The

3) Clean-Outs, All changes in direction shall be made with long radius
bends, 900, Aso, 22-1/20, 11-1/40, tee, or wye branches with
the straight-through opening plugged for a cleanout. Cleanouts shall
be installed in the building sewer between the building outlet and
the side sewer when the distance ;s greater than 100 feet or where
there is a 900 bend in the building sewer. All bends within the
sewer will not exceed 1350. Cleanouts shall be plugged to prevent
entrance of dirt, roots, or ground water. Plugs shall be sealed with
C rubber gaskets and secured against back pressure. Threaded plugs
l shall be terminated with an accessible cleanout outside of the
building line.
i
4) Size. The minimum size of any building sewer shall be determined on
the basis of the total number of fixture units drained by such sewer
in accordance with Table 4-3 of the Oregon State Plumbing Code. Each
single family residence shall be served by a side sewer discharging
directly into a receiving line.
C. Installation.
c
1) Location and Connection of Sewer Tees of Side Sewer Stub. The
connection shall be made to side sewer stub shown on the "as-built"
plana, The Agency does of guarantee and shall not be liable for the
accuracy of the measurements or locations of such plans. If the
sewer is not located at the measurement given, the installer shall
prospect three (3) feet in all directions from the distance and depth
i given, If riot so locate ', the installer shall contact the Agency.
If the Agency cannot locate the side sewer by different means, then a
line tap and gide sewer permit shall be purchased by the owner.
a) Direct Connection to Main Lines (Line Ta . No direct connection
into main sewer lines shall be made except by the Agency. When a
line tap is required, the perrson needing the line tap shall
purchase a tap and side sewer permit from the Agency and the
i
Agency shall construct the tap and side sewer.
i" b) Connection. Where two buildings are adjacent to ine another on
the same lot, each building shall have a separate connection pipe
1 to the receiving line. The pipes from each building shall be in
is separate ditches to point of connection on the receiving line. A
duplex may be served by one (1) tap and side sewer provided that
a deed restriction is placed on the property requiring the owners
thereof to be jointly responsible for maintenance of the building
sewers .and side sewer. A copy of the Gleed restriction shall be
submitted at the time of sewer permit application. No roof,
surface, foundation, footing, or other ground water drain shall
be connected to the sanitary systema
c) _Connection tooCCesspools and Septic Taroks.
1) Direct connection from all plumbing fixtures in the
building to the sanitary sewer system is required.
2) Any connection to a cesspool, septic tank, or kitchen
t.. grease trap shall be removed and proper connection shall be
made to she building sewer.
Page 45
k
3) When a private sewage disposal system is abandoned and no
longer to be used, all septic tanks, cesspools, and similar
private systems shall be pumped and backfilled in
accordance with Oregon State Plumbing Code.
2. Excavation. All excavations required for the installation of a
building saver shall be open trench work unless otherwise approved by
the Agency.
3. Alignments. All pipe shall be laid true to grade with the bells
upgrade. Pipe shall be carefully centered prior to jointing. The
bottom of the trench shall be smooth and free from rocks which may
[ injure the pipe. The pipe shall be laid on a firm bed throughout its
entire length, and any such piping laid in fill shall be laid on a
bed of approved materials and shall be adequately supported to the
satisfaction of the Agency.
4. Grade. All sewers shall be laid on a grade of not less than 1/4 inch t;
per foot for a four-inch (4") pipe and 3/16-inch per foot for a
six-inch (6") pipe.
I a) Special Release. If the grade of the side sewer or building
sewer is to be less than 1/4 inch per foot for a four-inch (4")
pipe, or 3/16-inch per foot for a six-inch (6") pipe, the
property owner shall sign and acknowledge a grade release in a
f form approved by the Agency. The effect of such form shall be to
release the Agency from all future claims for damages due to the '.
installation of said sewer. if there is doubt about the grade, a
grade release shall be procured before the pipe is laid. If upon
inspection the grade is inadequate, the grade release shall be
filed in the office of the Agency before backfilling takes
place. In all special cases, the installation of a back-water
valve will be required.
b) Elevation. In any buildings, structures, or premises in which
the house waste drain is too low to permit gravity flow to the
. sewer, the sewage shall be lifted by artificial means and
discharged to the sewer. Wherever a situation exists involving
an unusual danger of back-up, the Agency may prescribe the
minimum elevation at which the house drain may be discharged to
the public sewer. Sewers below such minimum elevation shall be -'
lifted by artificial means, or if approved by the Agency, a
back-water sewage valve may be installed. The effective
operation of the backwater valve shall be the responsibility of
the owner of the property served.
_., c) Sackfili. if common material is available which is free from
rocks one (1) inch in diameter and larger, it shall be used to
backfill the remainder of the ditch. If suitable material is not
` available, the 3/4-inch minus granular material shall be used to
backfill the trench to a paint six (6) inches above the top of
the pipe. The remainder of the ditch shall then be backfilled
with common material.
Page 46
1) A modified method of backfilling shall be used where the
house service laterials cross lawn, shrub, or planting
areas between the curb and the property line. In this
area, backfill shall be modified so that a minimum of
eighteen (18) inches and a maximum of thirty—six (36)
inches of compacted top soil shall be provided in the upper
portions of the trench. The lower portions of the trench
shall be backfilled as described above.
i d) Cover•. Cover on private property shall be not less than (12)
inches.
e) Sewer and mater Lines. Building sewers shall not be laid in the
same trench with water service pipes unless both of the following
1 '
requirements are met:
l) Separation. The bottom of the water pipe, at all points,
shall be at least twelve (12) inches above the top of the
sewer line.
2) Placement. The water pipe shall be placed on a shelf
excavated at one side of the common trench.
i 0. Testin . All building sewers shall be tested for leakage in the presence
of the Agency inspector prior to backfilling the trench. Sewers shall be
tested by plugging the building sewer at its point of connection with the
side sewer and completely filling the building sewer with water from the
lowest point to the highest point thereof. The building sewer shall be
watertight and have no visible leakage.
T
A tee shall be installed at the property line at the expense of the
is installer. After the test is complete, a plug shall be inserted in the
tee and securely wired in position to prevent dislodging the plug under
possible future back pressure. After a satisfactory test has been
performed, the trench shall be backfilled
