SANITARY SEWER MANHOLE
There shall be no physical connections between a public or private water
supply system and a sanitary sewer or appurtenances thereto which would
permit the passage of any polluted water into the potable supply. Sanitary
sewers shall be laid ten (10) feet horizontally from any existing or proposed
water line. The distance shall be measured edge to edge. In cases where it
is not practical to maintain a ten (10) foot seperation, the appropriate
reviewing agency may allow deviation on a case -by -case basis if supported
by data from the design engineer. Such deviation may allow installation of
the sewer closer to a water main provided that the water main is in a
separate trench or on an undisturbed earth shelf located to one side of
the sewer, and at an elevation so the bottom of the water main is at
least 18 inches above the top of the sewer.

Sanitary sewers crossing water mains shall be laid to provide a minimum
vertical seperation distance of 18 inches between the outside of water main
and the outside of the sewer. This shall be the case where the water main
is either above or below the sewer. The crossing shall be arranged so that
the sewer joints will be equidistant and as far as possible from the water
main joints. Where a water main crosses under a sewer, adequate structural
support shall be provided for the sewer to prevent damage to the water main.
When it is impossible to obtain proper horizontal and vertical seperation as
stipulated above, the sewer shall be designed and constructed equal to water
pipe, and shall be pressure tested to assure water tightness prior to backfilling.

"Uniband" or approved equal. Prior to placement, the top 4- inches of the manhole
cone and casting frame shall be cleaned and primed. The Uniband shall extend from
3- inches below the top of the cone section to 2- inches over the flange of the
manhole casting frame.
7. The casting elevations are set by plan. However, the castings are to be adjusted
in the field by the Engineer s representative, should a discrepancy occur between plan
grade and existing grade. New manhole ring and cover shall be installed to establish
grade. Maximum height of adjusting rings shall be 12- inches.
8. Backfill around all structures and all cuts under paved areas with granular material.
Trenches opening with 5 -feet of paved roadways shall be backfilled with granular
material in accordance with Section 211. Backfill under sidewalks shall be granular,
unless the walks are constructed a minimum of six months after backfill has been
in place.
9. The Contractor shall be responsible for verifying that all state highways, city and
county permits have been obtained by the developer prior to start of construction.
10. The Contractor shall be required to furnish the developer's Engineer with a set of
prints, marked in red pencil, showing actual sewer location and invert, to include lateral
location, depth and length. Such "as- built" prints must be received by the Engineer
before the final contract payment can be authorized. The sanitary sewer laterals and
stubs termination shall be indicated on the surface with a metal fence post set
immediately above said termination point.
11. All sanitary sewer lines upon completion will be required to pass a low pressure air
test. Said test shall be conducted according to ASTM 1417 -92, and shall be witnessed
by an Engineer and a representative of the Clay Waste District. The testing shall be in
accordance with Table 1.
12. Deflection tests shalt be performed on all flexible* pipe after the final backfill has
been in -place at least 30 days. No pipe shall exceed a vertical deflection of five
percent (5 deflection test results. *The following are considered non flexible pipes:
concrete pipe, ductile iron pipe and cast iron pipe.) The deflection test shall be
performed with a nine -point mandrel. Proving rings shall be available.
13. All mandrel testing shall be observed by a Professional Engineer for certification

3. PVC sewer fittings shall conform to the requirements of ASTM D- 3034 -89
specification. Fittings in sizes through 8" shall be molded in one piece with elastomeric
joints and minimum socket depths as specified in sections 6.2 and 7.3.2. Fittings 10"
and larger shall be molded or fabricated in accordance with section 7.11 with
manufacturers standard pipe bells and gaskets. Wall thickness of fittings shall be SDR
26 as defined in section 7.4.1 of the specifications. Gaskets for elastomeric joints
shall be molded with a minimum cross sectional area of 0.20 square inches and
conform to ASTM F -477 specification. Fittings shall be manufactured by Harco or
equal.
4. All sanitary manholes shall be "precast concrete" manholes in accordance with
ASTM C -478 and Section 720. 0 -rings shall conform to C -443. Kent Seal or
equivalent shall also be applied to all joints and between riser rings and castings.
Manhole step spacing shall be no more than 16- inches. Manholes shall be air tested
for leakage in accordance with ASTM C1244 -93, Standard Test Method for Concrete
Sewer Manholes by the Negative Air Pressure (Vacuum) Test.
A. Installation and operation of vacuum equipment and indicating devices must be in
accordance with manufacturer's recommendations and performance specifications which
have been provided by the manufacturer and accepted by the Engineer.
B. With the vacuum tester set in place:
1. inflate the compression band to forty (40) psi to effect a seal between the vacuum
base and the structure.
2. Connect the vacuum pump to the outlet part with the valve open.
3. Draw a vacuum of ten (10) inches of Hg. and close the valve.
C. Accepted standards for leakage will be established from the elapsed time for a
negative pressure change from ten (10) inches to nine (9) inches of mercury. The
maximum allowable leakage rate for a four -(4) foot diameter manhole must be in
accordance with the following:
Minimum Elapsed Time for a
Manhole Depth Pressure Change of 1 Inch Hg.
10 feet or less 60 seconds
>10 feet but <15 feet 75 seconds
>15 feet but <25 feet 90 seconds
For manholes five (5) feet in diameter, add an additional fifteen (15) seconds and for
manholes six (6) feet in diameter, add an additional thirty (30) seconds to the time
requirements for four (4) foot diameter manholes. For all manholes deeper than
twenty -five (25) feet, engineer will determine the applicable minimum elapsed time.
D. If the manhole fails the test, necessary repairs must be made and the vacuum test
and repairs must be repeated until the manhole passes the test.
E. If manhole joint sealants are pulled out during the vacuum test, the manhole must
be disassembled and the joint sealants replaced.
F. Manholes will be subject to visual inspection with all visual leaks being repaired.
5. Butyl rubber coating shall be applied around each manhole joint from 6- inches
above to 6- inches below each joint. The appropriate primer shall be applied prior to
applying the rubber coating. Inside joints to be filled with precoat plug material.
6. The manhole chimney's including all riser rings shall be sealed using Infi Shield
"Uniband" or approved equal. Prior to placement, the top 4- inches of the manhole
cone and casting frame shall be cleaned and primed. The Uniband shall extend from
3- inches below the top of the cone section to 2- inches over the flange of the
manhole casting frame.
7. The casting elevations are set by plan. However, the castings are to be adjusted
in the field by the Engineer s representative, should a discrepancy occur between plan
grade and existing grade. New manhole ring and cover shall be installed to establish
grade. Maximum height of adjusting rings shall be 12- inches.
8. Backfill around all structures and all cuts under paved areas with granular material.
Trenches opening with 5 -feet of paved roadways shall be backfilled with granular
material in accordance with Section 211. Backfill under sidewalks shall be granular,
unless the walks are constructed a minimum of six months after backfill has been
in place.
9. The Contractor shall be responsible for verifying that all state highways, city and
county permits have been obtained by the developer prior to start of construction.
10. The Contractor shall be required to furnish the developer's Engineer with a set of
prints, marked in red pencil, showing actual sewer location and invert, to include lateral
location, depth and length. Such "as- built" prints must be received by the Engineer
before the final contract payment can be authorized. The sanitary sewer laterals and
stubs termination shall be indicated on the surface with a metal fence post set
immediately above said termination point.
11. All sanitary sewer lines upon completion will be required to pass a low pressure air
test. Said test shall be conducted according to ASTM 1417 -92, and shall be witnessed
by an Engineer and a representative of the Clay Waste District. The testing shall be in
accordance with Table 1.
12. Deflection tests shalt be performed on all flexible* pipe after the final backfill has
been in -place at least 30 days. No pipe shall exceed a vertical deflection of five
percent (5 deflection test results. *The following are considered non flexible pipes:
concrete pipe, ductile iron pipe and cast iron pipe.) The deflection test shall be
performed with a nine -point mandrel. Proving rings shall be available.
13. All mandrel testing shall be observed by a Professional Engineer for certification
and a representative of the Clay Waste District.
14. The ends of laterals are to be plugged tight with a braced plastic disc or cap
capable of withstanding a low pressure air test without leakage.
15. Bedding for flexible pipe shall be No. 8 crushed stone from 6- inches below the
pipe to 12- inches above the pipe. Bedding for rigid pipe shall be No. 8 crushed
stone from 6- inches below the pipe to the spring line of the pipe and from this point
to 12- inches above shall be fill sand or equivalent. Manholes shall be placed on no
less than 6- inches of No. 8 crushed stone bedding.
16. Water and sewer line crossings and separations shall be in accordance with Ten
States Standards.
17. Trench shall be opened sufficiently ahead of pipe laying to reveal obstructions, and
shall be property protected and /or barricaded when left unattended.
18. No water shall be permitted to flow into the sanitary sewer system during
construction. Contractor shall utilize a pump to keep the water ievel below the pipe.
Pump discharge shall be directed to a storm outlet. Any pipe entering existing sewers
shall be plugged, with screw type mechanical, braced plug, until such time as all tests
on the sewers have been completed and the lines have passed all punch lists.
19. All sewer laterals installed by the mainline Contractor shall be bedded the same as
the main line sewer.
20. Forty -eight (48) hours notice shall be given to the Clay Regional Waste District
prior to the start of sewer construction. Also, 48 -hours notice shall be given prior to
any testing done on the sewer.
21. Manhole castings shall be stamped "SANITARY SEWER" (Neenah Casting R 1642 or
equal) and be self sealing type. Waterproof castings shall be Neenah R -1 916 -F1 and
stamped "SANITARY SEWER
22. The minimum slope for sewer acceptance by the Clay Township Regional Waste
District are:
Size of Pipe Minimum Constructed Slope
8 -inch 0.40%
10 -inch 0.28%
12 -inch 0.22%
15 -inch 0.15%
18 inch 0.12%
23. The Contractor shall provide measurements of the slope of the sewer for each
manhole section as construction progresses. Such measurements shall be certified by
a Registered Land Surveyor or Engineer and be available on -site for observation by the
District s Inspector. No more than three manhole sections can be constructed in
advance of such measurements.
24. In the event the Contractor does not meet the minimum slopes, the sewer section
and any other affected sewer sections shall be reconstructed to meet such minimum
slopes.
