Pspecifications which have been r entm b the manufacturer and aces etl b the District En ith er. P Y Pt Y 9 The vacuum equipment must be capable of testing the entire manhole, including the CBSfln and /ISBN rings. 9 9 B. With the vacuum tester set in place: 1. Connect the vacuum um to the outlet port with the valve open. pump p P 2. Draw a vacuum often (10) inches of HE. (5 psi) and close the valve. C.

The maximum allowable leakage rate for a four (4) foot diameter manhole le 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 fives 5 feet in diameter, add an additional fifteen 15 seconds and for manholes six for feet in diameter, add an additional thirty (30) seconds to the time requirements forfour he 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. 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 with plastic wrap shall be applied around each manhole joint from 3- inches above to 3-inches below each joint.

The manhole chimneys, including all riser rings shall be sealed using flex rib internal chimney seal manufactured by Cretex, NPC, or a District approved equal. The flex rib internal chimney seal shall extend from a minimum of 3-inches below the top of the Cone section to 3-inches over the manhole Casting frame or per manufacturers installation procedures if directed otherwise. Internal Chimney Seal shall be installed after manhole vacuum testing and prior to final acceptance. Water test may be done, per manufacturer or Districts recommendation, to provide assurance that internal chimney seal is watertight. 7. The casting elevations are set by plan, however, the castings are to be adjusted in the field by the District's representative should a discrepancy occur between plan grade and existing grade. New manhole rings) and Cover shall be installed to establish grade. Maximum height of adjusting rings shall be 12-inch on existing structure adjustment and 10-inch maximum on new construction. 8. Backfill around all installed or proposed manhole structures, sidewalks, bike paths and/or all paved areas shall be made with granular material (b-bmrow)or No. 8 stone, up to 18-inches below crosssection thickness (which shall include "Ns,. 53" stone depth). If more stringent backfill requirements are set out per city, town, county, or District specifications those standards shall be followed. Trench opening within 5-feet of the back of the curb of paved roadways, shall be backflled with granular material or No. 8 stone in accordance with Section 211 of the current INDOT standard specifcations handbook. 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. Initial asbuilts shall be presented to the inspecting engineer prior to final submittal to the District for review, otherwise Contractor shall be required to furnish the developer's Engineer with a set of prints showing actual sewer locations and inverts including lateral location, depth, and length. Such asbuiit prints must be received by the Engineer before the final contract payment can be authorized. Asbuilts shall be submitted per the Districts cu rent standard which can be fan nd at wwW.chwd.org. 11. The sanitary sewer laterals and stubs termination shall be indicated on the surface with a detectable metal post set immediately above the said termination point if full connection is not immediately made. 12. All sanitary sewer lines upon Completion will be required to pass a low pressure air test. Said test shall be conducted according to ASTM F1417-92, and shall be witnessed by a District employee or the Districts representative. The testing shall be in accordance with Table 1 as follows with 0.5 psi being added for each foot of waterabove the sewer line being tested.

Such measurements shall be certified b a Registered Y 9 Land Surveyoro than beavailable oon-site for aonstrute by the District's Inspector. en mare 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 installed with a minimum 14 gauge tracer wire tram the wye to the terminus. Upon lateral completion the contractor for the building or home will extend the wire from this temlinus to the building cleanout adjacent to the building.
