Air Pressure (Vacuum) Test.
5:40
for leakage in accordance with ASTM C1244 -93, Standard Test Method for Concrete Sewer Manholes by the Negative
5:42
A Installation and operation of vacuum equipment and indicating devices must be in accordance with manufacturer =s recommendations and performance specifications
the manhole, including the casting
which
and
have been provided by the manufacturer and accepted by the Engineer. The vacuum equipment must be capable of testing entire
298
riser rings.
7:34
B. With the vacuum tester set in place:
7:34
1. Connect the vacuum pump to the outlet port with the valve open.
7:36
2. Draw a vacuum of ten (10) inches of Hg. and close the valve.
10:08
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 AUniband@ 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 within 5 -feet of paved roadways shall be backfilled with granular
d a minimum of 6 months after backfill has been in
material in accordance with Section 211. Backfill under sidewalks shall be granular, unless the wal',,s are constructe
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 Aas 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 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 e wer
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 pla, 3 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 it n 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 ab. ve 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 3271AC 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 reguic,tions (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 some 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
done 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%
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.
25. Laterals are to be traced with a minimum size of 14 gauge wire from the Wye t) the terminus. The contractor for the building or home will extend the wire from this
terminus to the building cleanout adjacent to the building.
