For all manholes deeper than twenty-five (25) feet, the Engineer will determine the applicable minimum elapse( time. D. If the manhole fails the test, necessary repairs must be made. The vacuum test anc repairs must be repeated until the manhole passes the test. E. Ifmanholejoint sealants are pulled out during the vactIL1111 test, the manhole must b( disassembled and the joint sealants replaced. F. Manholes will be subject to visual inspection Nvith all visual leaks being repaired. 5, BLItyI rubber coating with plastic wrap shall be applied around each manhole joint from 3. inches above to 3-inches below each joint. The appropriate pruner shall be applied prior tc applying the rubber coating. Inside joints to be tilled with prec-oat plug material. Entir( exterior surface of sanitary sewer manholes shall be sprayed with a bituminous coating am all exterior gap exposure of riser rings shall be back plastered or grOLIted with no11s11rinl, grout. 6. The manhole chimneys, including all riser rings shall be sealed using flex rib interna clrininey seal manufactured by Cretex, NPC, or a District approved equal. The flex rR internal chimney seal shall extend from a minimum of 3-inches Below the top of the coif Section to 3-Inches over the manhole casting f1'arric or per manUfaCtUrCrS installatior procedures if directed otherwise. Internal Chimney Seal shall be installed after manhole vaCULun testing and prior to final acceptance. Water test may he done, per manufacturer oI Districts recommendation, to provide assurance that internal chimney seal is water tight. 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 cxistia grade. New manhole ring(s) and cover shall be installed to establish grade. Maxirnun- heieht of adiustine rinas shall be 12-inch on existine structure adjustment and 10-inc]- 8. Backfill around all installed or proposed manhole structures, sidewalks, bike paths and/or at I paved areas shall be made with granular material (b-borrow)or No. 8 stone; up to 19-inches below crosssection thickness (which shall include "No. 53'' stone depth). If more stringent backfill requirements are set out per city, towvn 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 baekfilled with granular material or No. 8 stone in accordance with Section 211 ofthe current INDOT standard specifications handbook. 9. The Contractor shall be responsible for verifying that all state highways, city, and county permits have been obtained by the developeI' 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 sliall 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. SLICK asbujlt prints must be received by the Engineer before the final contract payment can be authorized. Asbuilts shall be submitted per the Districts current standard which can be found at wwvw.ctrwd.org. 11. 'file 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 lull connection is not immediately made. 12. All sanitary sewer lines upon completion will be required to pass a lose 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 ill accordance with Table I as follows with 0.5 psi being added for each foot of water above the sewer line being tested. Sewer lines shall be subject to visual leak inspection at downstream manholes with all visual leaks being repaired and subject to televising requests by the District. 13. Prior to final deflection test (mandrel test) all mainlines shall be cleaned and tree of any debris. 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.

The 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 [low into the sanitary sewer system during construction. Contractor shall utilize- a pump to keep the water level below the pipe. Primp discharge shall be directed to a storm outlet in accordanee 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 tune as all tests on the sewers and all punch list items are colllplete. 19. All sewver laterals installed shall be bedded the same as the main line sewver, 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.

Watertight castings shall be bolt - down East Jordan 1022Z I PT and also stamped SANITARY SEWER. 22, The minimum slope of the sewer shall be: Size of Pipe Minimum Constructed Slope 8-inch 0,40% 10-inch 0.29% 12-inch 0,22% 15-Inch 0.15% 18-inch 0,12% 23. The Contractor shall provide ❑leaSUrements 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 avai lable 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 sloes not Meet the nlininlulTI slopes, the sewer section and any other affected sewer'sections shall be reconstructed to meet such nTinilmlill slopes. 25. Laterals are to be installed with a minimum 14 gauge tracer wire from the wye to the terminus. Upon lateral completion the contractor for the building or horrie will extend the wire from this terminus to the building cleanout adjacent to the building.
