SANITARY SEWER SPECIFICATIONS
FOR
C�AY TOWNSHIP REGIONAL WASTE DISTRICT
1. Standard specifications of the clay Waste District and Indiana Department of Highways
shail appiy for all work and materials. Pipe shall be instalied in accordance with Section
715.
2. Sanitary sewer pipe shall be PVC in accordance with ASTM D-3034 (S.D.R. 35) and
ASTM 2321. PVC pipe shali have grooved beil and gasket. The pipe shall be made of
PVC plastic having a celf ciassification of 124548.
3. PVC sewer fittings shall conform to the requirements of ASTM D-3034-89
specifications. Fittings in sizes through 8'� shall be molded in one piece with elastomeric
joints and minimum socket depths as specified in sections 6.2 and 7.3.2. Fittings 10" and
larger shall be molded or fabricated in accordance with section 7.11 with rnanufacturers
stondard pipe beils and gaskets. Wall thickness of fittings shall be SDR 26 as defined in
section 7.4.1 of the specifications. Gaskets for elastomeric joints shall be molded with a
minimum cross-sectional area of 0.20 square inches and conform to ASTM F-477
specification. Fittings shall be manufactured by Harco or equal.
4. All sanitary manholes shall be "precast concrete" manhotes in accordance with ASTM C-
478 and Section 720. 0-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.
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 casting elevations are set by plan. However, the castings are to be ad justed 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.
7. Backfill around all structures and a{I cuts under paved areas with granular material.
Trenches opening within 5-feet of pave roadways shall be backfilled with granular
material in aecordance with Section 211. Backfill under sidewalks shall be granular,
unless the walks are constructed a minimum of 6 months after backfill has been in-place.
8. The Contractor shall be responsible for verifying that all state highways, city and county
permits have been obtained by the developer prior to stort of construction.
9. 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 "as-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 said
termination point.
10. All sanitary sewer lines upon completion will be required to pass an in�ltration weir test
and a low pressure air test, unless otherwise directed by the Engineer. Said test shall be
conducted according to NCPI Standard Method, and shall be witnessed by an Engineer
and representative of the clay Waste District.
11. 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 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 mondrel testing shall be observed by a Professional Engineer for certification and a
representative of the Clay Waste District.
13. The ends of iateral 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 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
shall be �II sand or equivalent. Manholes shall be placed on no less than 6-inches of No.
8 crushed stone bedding.
15. Water and sewer line crossings and separations shall be in accordance with Ten States'
Standards.
16. Trench shall be opened sufficiently ahead of pipe laying to reveal obstructions, and shall
be property protected and/or barricaded when left unattended.
17. 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. Any pipe entering existing sewers shall be plugged,
until such time as all tests on the sewers have been completed and the lines have passed
all punch lists.
18. All sewer laterals installed by the mainline Contractor shall be bedded the same as the
main line sewer.
19. Forty-eight (48} hours notice shall be given to the Clay Regional Waste District prior to
the start of sewer construction. Also, 48-hours notice shall be given prior to any testing
done on the sewer.
20. Manhole castings shall be stamped "SANITARY SEWER" (Neenah 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 acceptance by the Clay Township Regional Waste District
are:
Size of Pipe Minimum Constructed Slope
8-inch 0.40%
10- i n ch 0.28�
12-inch 0.229�
15-inch 0.15%
18-inch 0.12�
22. The Contractor shall provide meosurements of the slope of the sewer for each manhole
section as co�struction progresses. Such measurements shall be certi�ed 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.
23. ln the event the Contractor does not meet the minimum slopes, the sewer section and any
other offected sewer sections shall be reconstructed to meet such minimum slopes.
