4. All sanitary manholes shall be precast concrete manholes in accordance with ASTM C -478 and Section
720. O -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 C 1244 -93, Standard Test Method for Concrete Sewer
Manholes by the Negative Air Pressure (Vocuum) Test.
A. Installation and operation of vacuum equipment and indicating devices must be in accordance
with manufacturers recommendations and performance specifications which have been provided
by the manufacturer and accepted by the Engineer. The vacuum equipment must be capable of
testing the entire manhole, including the casting and riser rings.
B. With the vacuum tester set in place: 1. Connect the vacuum pump to the outlet port with the valve
open. 2. 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 mist 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) `eet 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, the
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 chimneys, 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
Engineers 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
within 5 -feet of paved roadways shall be backfilled with granular material in accordance with Section
21 1 . Backfill under sidewalks shall be granular, unless the walks are constructed a minimum of 6 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
asbuilt 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 the 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 District. The testing shall be in accordance with Table 1. Add 0.5 psig for each foot of water above
the sewer line being tested.
12. Deflection tests shall 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 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 representative for certification and a
representative of the 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. 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 327 IAC 3 -6 -9.
17. Trench shall be opened sufficiently ahead of pipe laying to reveal obstruction, and shall be properly
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 level below the pipe. Pump discharge shall be directed to a storm outlet in
accordance with state and federal laws and regulations (327 IAC 3- 6 -20). 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 District prior to the start of sewer construction. Also, 48
hours notice shall be given prior to doing any testing on the sewer.
21. Manhole castings shall be stamped SANITARY SEWER (Neenah Casting R 1642A or equal) and be
self - sealing type. The casting flange shall be 34 inches and the clear opening shall be 24 inches. Waterproof
castings shall be Neenah R- 1916 -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`0 12 -inch 0.22% 15 -inch 0.15% 18 -inch 0.120
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.
25. Laterals are to be traced with a minimum size of 14 gauge wire from the wye to the terminus. The
contractor for the building or home will extend the wire from this terminus to the building cleanout adjacent
to the building.
