and representative of the clay Waste District. �
11. Deflection tests shall be performed on al{ flexible* pipe after the �nal backfiil has been in
place at least 30 days. No pipe shall exceed a vertical deflection of 5 percent 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.
12. All mandrel testing shall be observed by a Professional Engineer for certification and a
representative of the Clay Waste District.
13. The ends of lateral are to be plugged tight with a braced plastic disc or cap capable of
withstanding a low pressure air test without leakage.
14. Bedding for flsxible pipe shall be No. 8 crushed stone from 6-inches below the pipe to

Contractor sholl utilize a pump to keep the woter level below the pipe. Pump discharge
shall be directed to a storm outlet. Any pipe entering existing sewers shall be plugged;
using a"screw" type mechanical plug, until such time as all tests on the sewers have
been completed and the lines hvve pa�se� aU punch li�ts.

main line sewer.
19. Forty-eight (48) hours notice shall be given to the Clay Regional Waste District prior to

done on the sewer.
20. Manhole castings shall be stamped "SANITARY SEWER" (Neenoh Casting R 1642 or
equal) and be self-sealing type. Waterproof castings shall be Neenah R-1916-F1 and
stamped "Sanitary Sewer".
21. The minimum slope for sewer acceptdnce by the Clay Township Regional Waste District
are:
Size of Pipe Minimum Constructed Slope
8-inch 0.40�
10-inch �•28%
12-inch �•22�
15-inch 0.157
18-inch 0.12%
